Top speeds

[Educated_Hate]

I was inspired by the motorcycle thread where the guy went 205 I had seen it on another forum a little while ago and decided to push my old 94 GAGT to the limit I hit 115 before my car was shaking to the point where I was pretty scared. Whats the fastest you've ever gone in your GA?

[WoR]

116 in my '91 4 door LE w/quad 4. Not bad for a 4 door 4 banger ugly family car. After i got there the computer said no no. Didnt have much more to go anyway, maby 118 and it wouldhave stopped.

[Artic]

120 in my old 01gt 80 in my 04 :)

[Chain]

My 97 GA would go faster but its held back at 107.
My 71 mustang after the rebuild would bury the spedo. But for sure was over 135 smooth as glass.

[Entombed GT]

about 110 (very stupid when I think back to it) playin around with a Cougar on I-75 in Sarasota.

My man was in the car and boy did I get a *****in for that one.

Dumb. Will never do that again.

[BleakGT]

sorry, the above post was me :)

Jeff always forgets to log out when he is done :lol:

[mthegodfather]

110 in my GA
150 in my Prelude

[GT2000]

Does anybody know in fact if the top stock speed in the 99+ GA GT is 150 like the speedo says? I haven't been able to find anything on that. Not that I would go that fast anyway lol, just curious. =P

[LoneRangers15]

Something I have found out from carrying my GPS with me is on my car the speedometer is less accurate as speed increases. When the GPS says 35 mph, my speedo says 35 mph. When my GPS says 75 mph, my speedo says 80 mph. This is all explained by math that I am too tired to remember.

[GT2000]

Yeah a couple guys I go to school with hit a tree at 100+, not sure the exact speed, two of them are critical and one lost an ear and is pretty beat up....like I said no need to go that fast, just curious if it was possible at stock.

[birdhouse]

I had my old 95' up to 116 before it shut off, and now my 00' SE shuts off at 106... Kind of pisses me off that I don't have that additional 10 mph, but hey, whatever...

the GA looks like it could go faster then it really can in reality - especially the SC/T GA. That is one hot-looking car
in my opinion!

And speaking of that... does anybody know what the
top speed for the SC/T GA is? I'm just curious.


Same as a normal GT... only the hood and spoiler are different :( no supercharger so it shouldn't be called SC/T stupid GM. Anyways, I believe that the governer is at like 110-115... beyond that you'd need some higher speed rated tires and a GM techie to remove it for you (good luck, but I know someone has it done here, read about it once).

Seriously though, the video that Pacman made makes me want to SC my GA as soon as I get some real money coming in. If you haven't seen the video, here's the link (http://www.gaownersclub.com/forum/showthread.php?s=&threadid=31577) .

[1996v6corsica]

car was shaking? you need new tires man.. my old corsica hit its limiter at 106.. and it felt like i was cruising at 55.. now.. my celica on the other hand.. i hit 100 in it and it felt like it was gonna fly off the road.. front suspension is shot and the fron bumper/ fender is all jacked up... so it acts funny in the wind

SHE JUST WOULDNT LET ME GO ANY DAMN FASTER!!!!!!!! It sucks hitting 110 and then it kicking you down. Drives me crazy.

Dont feel bad man, i used to drive a '93 single cam grand am and i got her up too 104 once and that was on a level road, a good tail wind, and 4min. on the floor. I loved that car, hated the motor...

[TA^Guy]

Took our GA all the way to 127mph
My '92 Z28 went over 150mph
regularly go 155 on my YZF600R
and have done 173mph on a '03 R1.

[WoR]

I cant imaging going that fast on 2 wheels....

[UGAkilla]

127 in my 00GAGT
135 in my dad's Corvette (Would have went faster, but it was dark)
Been to 150 while my dad was driving.

HELL YEAH!!!

Sometimes i will stop at 105 sometimes at 108. This time it was 105. That thing suck so much gas at 100. The ride is ok at that speed but their is a little wind noise.

[WoR]

Wish i could run 105@3250 rpm's. Thats just not right, that motor doesnt make all its power at that rpm, borrow a buddy's smaller rims/tires and see if you can go faster with those :P you should be turning alot more rpms when your maxed out than that.

[EKling]

I had my car up to 105 for a KCGAC club meet and the thing could go much faster then that. My brother also had the silver GT up to 120. at 100 I felt like my brakes were going to rip off they were shaking so bad. (metallic pads)

It will accelerate faster but it would actually go slower if you used a shorter overall tire.
The vehicle speed will be inacurate due to the shorter tire. The actual distance traveled in one rotation of the tire is less, and if the vehcile thinks it needs so many rev's to equal a given speed the speedometer will be inaccurate and the speed limited governor will kick in sooner than actual 105mph.

If you want to trick it into going faster a talled tire is what you'd want. Although you suffer from slightly slower acceleration and a speedo that reads less than your actually traveling.

your 91 is a 3-speed so your rpm are going to be higher, With a 4speed like mine it going to be a little lower. In my moms malibu the gearing it so low you can hit like 75 in second if you push it. In my car it takes like a min or two for the car to get to 100. After 80mph the car has no power

[WoR]

OK, i guess what im trying to say is that your last gear is too high. If you hit 105mph maxed out and your only running a little over 3 grand then the car has alot more potential, you just need to get those rpm's up were the power is to overcome the wind resistance.

[grandamgt01]

I have hit 134 in my 2001 GT on the highway.

[WoR]

its not a grand am, about the exact opposite, an '89 Lincoln Town Car... Wrapped the 85mph speedo back around to 30!! Didnt shift into overdirve until it was at 5mph. Not bad for a stock low ouput 302 giant brick.

[gbe357]

104mph....still plenty of acceleration to that point...then...buzz..limiter hits and it stops going faster.

[kdiddy]

105 or 110 What ever the speed limiter was in the 99grandam SE

105 (speed limiter) in my 94 sc1 (sohc 85 monster hp)

124 in my 99sc2 (speed limiter again)
I might have run from the cops on that one im not sure...

kdiddy

[RocketFast321]

my dad has a 91 Chevy 1500 305. He he made the speed-o restart on it a few times he also wrapped it back to 30

[H.O. Driver]

I have had it up to 135 on the highway, had room to go higher but it wasn't worth it. I have DHP so the speed limiter is set to 299mph ;) Other wise a stock pcm on a 99+ GT is 126. Regardless of what the speedo says ;)

What exactly is DHP?

[Scrapy918]

114 mph and that's when the governor kicked in, and the car wasn't shaking I was just pissed that it would only do 114mph

[H.O. Driver]

Its a reprogrammed PCM.

[Rayz]

Has anyone done the calculations for their top speed using their tire circumference, final drive ratio and RPM and come up with an accurate number for their top speed?
My 64 GTO Toped out at a calculated 137 MPH, I still had RPM but it hit an aerodynamic wall and wouldn’t go faster.
My 72 Firebird 400 Toped out at a calculated 155 MPH, I wouldn’t take any fasted. “The
Telephone poles looked like a picket fence”

My 74 Nova SS (350/350 – 700R4 – 308 Positraction) went a calculated 125 MPH, it had lots more but I was getting old by then (1995).

Tthis could be handy.

[95GAinFLA]

my 95 went 110 easily. no rev limiter yet either...bridge ran out. i need a longer road..

[sunrunner_pei]

Here's a pic of my '99 SE at 140 KM/H... I've taken it to the govoner of 112 MPH on a few occasions. I haven't pushed the '03 that hard yet. Probably never will either.

[sunrunner_pei]

...and here's a pic Kelly took of me travelling at over 90 MPH that same day. :lol:

[doobiess]

ok well my comment in response to all those that were... threatening me and saying they can have me fined heavily... for removing my cat..

OK then you people are doing 110mph on the highway... and you say i should get a fine?

I will up the anti one, this was back in my live to die stage of my life, :lol::lol: This was done on RS-A's that were bald with 50,000 miles on them.

[TheNewLMHDesign]

Doobies, let me say, do with your car what you wish. As far as a side comment. That dude in your sig really scares me.

And as far as what buchajo was asking. 110 MPH really doesnt bug me at all. I drive like this all the time, so I have complete control over the car. I also drive the same route to and from school every day, as well as to and from work. So I pretty much know the route. But ehh, i guess even when driving to places i dont know its really never mattered. I am very add, and driving the speed limit.......is just way way to slow. As far as the pictures, its just quite easy. You dont look through the lense. You just turn on the LCD monitor and line it up, if your a good enough photographer, it should turn out fine.

[doobiess]

LOL that dude is from return of the living dead.... your the first person to comment on it so far

[RocketFast321]

the way i take pics is to keep the camera in my lap and ready. Point and shot. And thats it.

[sunrunner_pei]

pictures of your speedo, while you're going at that speed?!

I can only speak for myself... But the pic was the last thing on my mind. My eyes were on the road, not on the camera or the dash. I just held the camera in one hand and snapped the shutter. I took a couple pics, then put the camera away before getting on the gas again. Only one of the pics turned out, which was the one posted. :)

BTW, I do NOT recommend anyone attempt it themselves. I did it out of my own stupidity.

Well breaking the law always comes with the chance to be caught and fined.

I nearly never drive the speed limit. In residental areas I won't drive more than 5 over if that (not counting the ones when they don't catch me, just warn me or I talk my way out of it). But on the open road 10-15mph over, and highway at night with no traffic... limitless.
Probally the same reason I have five tickets since april of this year. I never claim to be prefect, and you'll never hear me cry about getting a ticket. Because like 99% of the other people out there, I usually deserve it when I'm caught.

[aurorabusa]

I just got my 04 se1 but i have pegged the speedo on my 2002 Hayabusa. It pegged at 185mph at 9500 rpm and i ran it up to 10100 on the tach.I was tucked in pretty tight but the bike was real stable

[MagusXIII]

I have gone over 120mph in my ZX2 because I cut the single wire that reads data from the vehicle speed sensor and sends it to the governor. Of course, I was able to get away with cutting a wire because I had no cruise and it is a 5sp. The speedo was buried at 120 and was past it a little bit, but the tach climbed a bit higher. I was driving on Ohio Route 8 between Cuyahoga Falls and Peninsula. For those not familiar with the area, there is a straight section that is 1.5 miles long.

For those with lots of shaking, I bet that is most likely the tire balancing and/or tire quality. My Dunlop D60-A2 tires on steel rims would shake at the 120 mark. Yet when I placed Bridgestone S-03 Pole Positions on the car mounted on aluminum alloy rims and mounted/balanced by The Tire Rack, the car was smooth as glass at that speed.

[RocketFast321]

I had three people in the car with me this last weekend. We was coming back to town. Had the music up so you could not hear wind (very loud) It was dark no cars on the road. We jamming and out of no where the car starts jerking back and forward. Turns out i had the car peg at 105 and did not know it. That was too fast for me at the time so i set the cruise at 85.

Same speed as if the GT's removed their limiter. It's hit 143 and is pretty well done after that. The supercharger just gets it there faster.

GT's are fuel regulated (Shut off) at 127 from the factory. Anyone that tells you they've gone faster either has an out of wack speedo, removed the limiter or is full of crap :)

[urweak]

electronicly controled at 105-108

[DarkPhoenix]

I havn't taken my GT to top speed yet, but my Formula I have had to 120 before the Governor said, "no!"

My Talon I've had it up to 145, but I ran outta revs, dam short gearing!!

My T/A i had up to 140, and then I saw a cop!

[Duster]

I hit 105 in my 94 Grand Am i think it was and i hit a patch of pebbles ont the road from a dirt path of to the side and i spun out luckly there where no cars around and it was a wide road! After that i promised crystal(cars name) to never scare her like that again and to save it for a dragway

[HondaCivicsSuck]

i had my GA up to 140 and shut it down. kinda scary to go that fast in a GA

[GrandAm95]

the fastest my GA did was 112mph when the gov. kicked in. my lumina stops at 103 grrr which is where the gov. stops the car. the fastest i've been was 180mph in a BMW over in Germany, at those speeds the trees look like a plur and the white lines looks like its just one line

[Bruce Gabriel]

When the need arises to go fast a friend who's a pilot & I will go rent an airplane for an hour. In spite of the recent tragic crashes ( If you have to abort a landing 'cause you can't see- Never try again!!) flying's still the safest mode of travel.

[Cacicgt7]

There's my speed! Took awhile though.....

[jds_truck]

ya i did about 110 area as wel govener stops ya there thats why i want dhp so no stop speed hehehe

[Customized]

I did 107 and got stopped by a pig, for a nice 263$ fine

[zomb]

105 up a bridge on the express lane, slowed down at the top to a steady 90 mph and followed another car doing the same for 2 mins.... was stupid because I had broken engine mounts and was in my 93se

and 85 in my 92 SE before it was shaking so hard that I thought the dash was about to fall to pieces.... Ti-rods (sp) or something could be the cause of that. Also, both times speeding, I was behind 2 other cars speeding, so I took the opportunity to see if I could keep up before slowing down and getting back into the slow lane.

[510flynn]

140 in my 91 2 door w/a 2.5 and 5 speed tranny and clutch. still didnt find the govner!!!!

[2003 GAGT SC/T]

I haven't maxed out my 03, haven't got used to the tall gearing on it so whenever I see I'm doing 2500 RPM I think I'm flyin but only goin 85 - 90

My 97 SE I always topped out at the limited 105mph. Once I set the crusie at 100mph and the car actually held there the entire time (45 min trip, should taken me 1.5 hrs lol)

I got my 01 Tiburon up to 137mph on the mass pike once. That was interesting considering I had two ppl plus me in the car and it woulda gone faster, but the radar dector went off so the brakes went on.

This takes the cake. in 1997 when the c5 Vetts came out my dad was a salesman at a Chevy dealership, and when they got there first one in we got to take it out. The thing idled at 80mph, and he pused it to 165mph on one strech of highway. Yeah that was a rush!

[GA2002GT2]

I had my ecu tuned at a local dealership. After thet having things changed I went and maxed it out. Took my ga up to about 148 mph. Then my buddy in his SHO keeped going. It was fun at hell. I think my girlfriend had to change her panties after thou LOL.

[Snoochies]

110 in her 99 GA
160 in my 95 Z28

[want2modmygt]

i havent maxed my car out yet. im waiting to get my level 3 license so i can drive after midnight. if i get pulled over that wont happen, not to mention my parents will sell my car if i got a ticket for 105-107 (my cars gov supposedly)

[Yuppyweird]

ive taken my 95 ga se 3100 to about 115 and then the gov kicks in it really dosnt take that long to get there either anyone know what the top speed on a 95 se 3100 would be without the govener and by any chance how about stock hp/torque?

[mattw]

well i have beat all of you well not in my new car i had a 97 twin turbo toyota supra i have been at 180 mph slowed down to about 60 and my front tire blew so i told myself i wouldn't do that agin

[GTon9teens]

cruised at 126 with 2 other people in the car- with RPM's to spare, didn't get to governer, car handled really well, a cop passed me in the oncoming lane, detecter didn't go off, just kept going
did it once, and dont plan on doing it again

[ixi0n]

ive had my 00GT up to 142......ill get a pic as soon as the weather here warms up again.

[Night Wolf]

1993 Coupe DeVille - hit the speed limiter.. many times. the limter is 110mph, but with my new wheels/tires, it isn't accurate, she was turning over at 4,200RPM in 3rd gear... I did the math and it came out to be 122mph. There was alot left too, it was noisy form the wind (recessed windows) but once i start drving her again, I am getting the performance chip which removes the speed limiter. On this car 2nd gear lasts until 85mph, then it shifts into 3rd

Now that I have the GPS, I want to take the '93 up and see what the limiter really kicks in at.

The Olds... well, just until last week I had old, worn, dry-rotted, off-balance tires so I never took it above 80. but with the new tires, and GPS, I wanted to see what the 16 year old, 127k miles 3800 V6 could do.... it was in the day and the road was clear, I had my foot down, slight incline going up and my max speed was 113mph.... only because I had to slow down for traffic up ahead... when I get a chance at night when the road is dead, I want to see what it'll top out at... I know there is a speed limiter somewhere... where it is though, I don't know. The Olds has the sporty FDR, and while the 1-2 shift is the same as on the '93, the 2-3 shift is around 75mph... this car, for what it is, pulls pretty good (it is my slowest car)

This is also the only car I tested the speedo with, 60 and under it is dead-on accurate, but when it says 75 I am really doing 80... that is at the edge of it's readings though, so no big deal.

The '79 obviously has no limiters, I don't know how fast you are going when the speedo goes past 85, past the trip odometer and then starts to go down inside the dash to the point that you don't see the needle anymore, then even when looking down into the cluster, you don't see it... but my bet was over 100.... those tires are really old, really worn, sidewall damage (curb rash) and kinda off-balance.... so I am kinda hesitant about reaching triple diigt speeds in a 4,500lbs boat.... but, the ride is smooth, the car glides along like I am doing 70, and if it wasn't for the engine being really loud right now (*exhaust leak*) you woudln't even hear it.

Something I found out though, the car, in stock form, can actually reach it's top speed in 2nd gear. I think in stock form the top speed was about 115mph... that is because when shifitng into 2nd at 55mph, it shifts around 4,300RPM, but when shifting into 3rd (top gear) around 90, it is only shifting around 3,800RPM, so if you had a tach and manually kept it in 2nd, it would reach the top speed, with revs to spare.... I need to get a tach, and once I fix the door latch, I am going to see what she'll do with the GPS.... but with the aerodynamics of a brick on top of another brick, high side wall (235) tires, and stock 180hp, there is kind of a limit, but even at 70, if i floor it, downshift into second, secondaires open and it'll push you in the seat... I can't wait to see what it'll be like when even some basic work is done to her :)

112 in my 04. it tried to stop at 110, take foot off the gas, and push easy on it, and she goes up more.

Yea, it it senses that a tire is spinning slower than the rest it will assume its going flat, this is only after a decent amount of time. Plus it will go off if you have a bad abs hub :(

I am not sure, why they did that, but there is no lights behind them that I know of, so I am not really sure why they are there. I don't think the white face gauges have opening behind them ;)

LOL:lol:

[Night Wolf]

well, some updates....

the Olds still remains at 113.... but like i said, I had to slow down, so top speed is uncomfirmed for now...

the '93... I had the GPS with me... it topped out at 111mph witht he speed limiter.. I will be buying the performance chip to remove that limiter once the Spring hits...

the '79... kinda disapointed, but I was going up an average average grade hill, and for some reason I don't think the secondaries were fully opened.... and I also let off for a bit then got on it... but so far I topped it out at 106mph... I thought it would be more, but going up a hill, the car and all the weight on boardf was tipping 4,700lbs, and no such thing as aerodynamics.... trow in a stock 180hp engine... and I guess 106 wasn't too bad... I wonder what she would do on flat road... that was in 3rd (1:1) and the final drive is a 2.28... so that isn't helping top speed either...

to keep myself from sounding like an idiot.. the hp on this car dosn't really matter... stock, it has 320ft-lbs torque at 2,000RPM... that is what gets the luxury liner moving :)

[Customized]

Whats the limit on the 2.2, I've hit 107 but got nabbed by a cop!!
Me and my buddy in his 99 Mustang v6 convertible were racing around 2 am on I-95??

Matt

[RocketFast321]

around 105-110 :)

[Vinaashak]

Ga - 107 with limiter
GTP - 141 with no limiter, ran out of road. It runs a bit warm up top like that though so i dont like to do it much. There was that z28 on the highway. I took it up to 140 and was walking away then i saw a spike of 14.3 degrees kr and shut it down

[MagusXIII]

Took the Cav up to its limited speed of about 107-109mph earlier this week. The Hyundai Accent that was also doing the same thing hit the same limited speed as we stayed dead even.

It was not a street race but a friendly top speed contest.

[GAGTRA]

ive got an '04 Ga Gt took the governer off and hit 147 mph real slow gettin up there though took me a good 5min (well it seemed anyway) to get from 140 to 147 and i still had 500 left on the tac.

What do you have done because i dont really believe that? just a few little tricks:D

[Vinaashak]

And this make it more believable because?

You have at least a pcm, and the only other people i know that have got to that speed before all had boost.

Can we say "heat soak?" Yea my friend's got a '96 Bonneville SSEi w/ the Series II S/C, sucker loves to heat soak, especially after a few runs at the track :lol:

I've been to 115 in the Altima. Only about 110 in the GA, but it felt like it could keep going, I'm not sure where the governor is, most cars in this class are limited to ~128 I believe. I know that Bonneville has the fuel cutoff at that speed.

I am not sure, why they did that, but there is no lights behind them that I know of, so I am not really sure why they are there. I don't think the white face gauges have opening behind them ;)


From what I've heard... only the 99 GA has a tire pressure sensor. Supposedly GM took them out for 2000, and didn't bother to design a new gauge face.

[Carson]

I have a '95 GA and i've gone til it hits the steering column (my dashboard only reads 110 {SE}...so i'd guess it'd be bout 120 ish) ....then it SHUTS OFF! yes just shuts off...and to ones surprise *rolls eyes* NO! your steering wheel doesn't lock up! haha (inside joke)....and i'm sure it's still got more kick....since the last gear shifts at 90! now if that don't piss u off more! lol...my bud almost crapped his pants....and it didn't feel to even be going that fast....and for him to say he's gone 160+ in an older ta! BS!

GO DAWGS!!!!!!!!!!!!!!!!!!

All in fun Man..

[KM96GASE]

you got hella nice dad! my dad would never go that fast anyways. The fastest i've gone in my 96 GASE was 105 on freeway. I couldve gone faster but there was a curb. and after that, i realized it wasnt worth risking my life. So when i race random ricers, i just go up to about 60-70(enough to beat most ricers) and just put my blinkers on for the nice feeling!

[xbomb]

I did 125. Im currently looking into the dhp's.....maybe ill get one

[shagmobile]

ive had my grand am going 120 on the highway... it was fun:D

1990 Grand Am- 75mph on the back of a flatbed towtruck :(
1993 Taurus SHO - 145mph, smooth as glass, Not even close to redline. :eek:
1996 Contour GL - 120 mph with room to spare, a little too scary w/o suspension mods.
1997 Mustang Cobra w/ mods - 180 mph closed track, man that was fun. :D

[AleroGL]

107mph

[neomnj]

i hit 107 and the car stops giving it gas, 2001 pontiac ga se 4 door. how do i kill the speed limiter. would the jet module be a help or something

[not2good]

I went 160 im my friends GaGT with a state troper behind us our friend ofcourse

[GAGTRA]

160 in a ga? boost or not? cuz unless his running boost i highly doubt that. and how do u know you were going 160, my speedo only goes up to 150.

[TA^Guy]

Just broke my personal all time top speed tonight...
New personal top speed... 182mph.
Had more to go but backed off because I was coming up on traffic... and fast.

Maybe 160 kmph, but I would put money saying it's not 160mph.

My '92 Z28 lowered with mild modifications and a reburnt PROM topped out slightly over 150mph and that was with a TH700R4 tranny backed by a tall 2.73:1 limited slip differental.

It's going to take a heck of alot of power to push a GA to 160mph.

I post that at 2am when I was tired but now rereading it I just realize I forgot an obvious point... there is no Police car that will go 160mph, unless your area gets ultra cool exotics or special patrol vehicles. Even a normal Z28 without roof lights, 4L60E tranmission and standard 3.23:1 gear ratio will just hardly get close to 160.
Sorry I call :bs: on this one.If you want to prove it I have a machine to pace you with.

[GAGTRA]

New top speed record for me not in my ga but still....160mph riding an '05 susuki GSX-R600. my best friends bike he let me ride it tonight and told me to go as fast as i feel comfortable going. scariest shit ive ever done. but then again im getting an '05 kawaski ninja ZX-6R 636 in about a week or 2 hopefully.:O

[CharlesP2001]

My Grand AM will do 107mph before the limiter shuts me down. It ticks me off because I'll only be at 4,300 RPM!! And she's smooth as glass at that speed, and I know she can do more!

I've heard that bypassing the limiter will make a stock 3.4L GA do about 121MPH which is awesome for a 4 door SE. Some moderate modifications can push the GA up to 145mph.

[SilverGA2001]

In my GA, held an indicated speed of 134 in 3rd, oddly if I keep it in drive it stops every time at 120. I'd like to have a GPS unit to check the actual vs. indicated though.

In my 02' Formula, got to 147 and decided this was taking up vast amounts of road very quickly.

In my friend's '99 C5, indicated 149 on his heads-up, which is VERY nice to have at that speed. Though with my father's GP GTP with heads up, I pass the speedo read out at 110 and have to rely on the heads up all the way to 124.

[CharlesP2001]

You must have some mods to do that. And you had to have bypassed the limiter. Most GM vehicles have limiters (their trucks at 100mph and many cars at 105mph) and I hate them!

IIRC, the factory GT limiter is 120ish. Apparently if you keep it in 3rd, it gets around it. Only engine mods are some better plugs, Taylor wires, APOC, and Borla. I know others that have done this with the 3rd gear get-around. Like I said though, I'd like to have a GPS unit to see what it's actually doing, but according to the speedo, you can sustain 134, though your pushing your RPM's to the very end of the road. If I have a chance, I'll put someone in the rear seat behind the driver and snap a pic.

You would be surprised the difference between 120 and 140. With a car that has the frontal area like a Grand Am that 20mph can be a big difference.

[robry]

I just had my car out on the one highway very late at night. I have a DHP so no limiter. I was able to wind out 3rd gear to somewhere around 130-133ish, however I have 18s, and my speedo is definitely off. My guess is I was in the neighborhood of 140mph :) Maybe I'll try it with GPS sometime.

[Kanati]

160mph riding an '05 susuki GSX-R600

Indicated... Don't forget that with bikes. The speedo is most likely 10-20 mph off at that speed. So you were probably closer to 145-150.

My top speeds... 90 in the GA. Just not made for top speed runs so I keep it down in mine. :)
150 in the WS6.
175 INDICATED on my GSXR750.

It's just not bikes but cars also.

[Kanati]

Yeah, unless they are running a yellowbox on the bike it's almost always off by 10% or so. I haven't seen anywhere near 10% on my cars, but you are definitely right. Cars included. :)

[CharlesP2001]

I tried that 3rd gear thing mentioned earlier unfortunately it doesn't work on SE Grand AMs. I still topped out at 107 and had the engine pull back. The really exciting part came when I passed a cop parked on the side of the road going about 105MPH. Luckily he didn't have his radar on and all he did was follow me (riding my tail I might add) for 3 miles or so. I was very glad to see him turn around and head the other way.

[Desert Stallion]

Well, let's see. The '89 GA has gone no faster than 90 so far, but it takes a little while to get the 2.5L to pull the car along that fast. ;)

Now, my turbocharged Mustang LX coupe has gone 128mph... in a quarter mile, and roughly ten and a half seconds. :travis:

Cars included. :) My top speed in a car was calculated by a friend using the overall tire diameter, gear ratio, final drive ratio and engine speed. He knew the formula for it and came out slightly over 155, so with head wind and rolling resistance it was most likely around 150 or so.

The best way to positively know your speed other than being radar'd is to use a GPS unit.

[Import_Sound]

i made 107 when the computer stopped me, kinda sad too i had alot of room left

[replica9000]

I had my GT up to 140 while racing a bright orange Lamborghini Murcielago for 15 miles on 295

[mandi]

The Beretta has gone 140 mph. Here is video to prove it....
http://www.berettaspeed.com/canada/Videos/Canada's%20Top%20Speed%20Run.wmv

The Grand Am is still governed at 108 mph.

The Grand Prix is also still governed 125ish.

The Cobra has only been to 125 or so.

You went 140 in a Grand Am GT with a couple bolt ons? Thats pretty impressive.

You have worse aerodynamics and a larger front area than this Beretta.....so it takes more power. I'm surprised DHP's programming, cat back exhaust, and intake were able to do this.

Plus, you have 3.29 gearing, verses the 2.93s in the Beretta....so you would of had to of gone to 4th gear.

Well that's what teh speedometer told me, plus I had 15 miles to get it up there. I could have gone faster, but on Memorial Day weekend I wasn't gonna be the first car for the troopers to see.

[replica9000]

I don't have any other ways of testing my speed other than driving by things the cops use to show you your speed, and usually both my speedometer and the radar have agreed fairly accurate up to 90mph so far, and I don't know anyone willing to be in my car at 140 filming either. Basically what I get from what you're saying is that not that my car can't do it, but that the berreta can do it faster.

[mandi]

So at ~4450 rpm (4th at 140 mph) you are saying you have 150+ whp? I doubt it, considering you have a DHP flash, intake, and muffler/cat. At best, I think you might have 150 PEAK hp (at roughly 5k rpm). Certainly not 500 rpm before this. I think it's likely your speedometer is optimistic.

Where did I come up with 150+ whp? Its known that it takes almost exactly 130 whp to get a Beretta to go a true 130 mph(going off of multiple dyno charts and top speed runs of ungoverned Beretta's). Assuming your GA has the same aerodynamics (which it doesn't...but lets assume), to go 140 mph you will need ~1.16 times the power............you are going 1.077 times as fast [140/130], and since aerodynamic drag increases exponentially with speed (you need four times the power to go twice as fast....so 1.077 * 1.077= 1.16), you will need 150whp and change to overcome the aerodynamic forces at 140mph.

And again, that's for a Beretta with a smaller frontal area and better C.D.

The only reason *I* went 140 mph is because I had a 8-10 mph tailwind. Since then, I haven't gone past 135 in calm weather.

So YOU do the math and tell me whether you actually went 140 or not?

[replica9000]

Well how about you come to RI and I'll give you a ride.

[mandi]

Okay. But I live in Iowa, so thats not going to work anytime soon.

I'm just saying your speedometer is likely off at that speed.....or whatever you are using to measure your speed.

[Krusing]

110 in 5th gear, it would go faster in 4th gear but i don't like keeping the engine at high rpms

note:that was before the wing was put on, i'm probally slower now :(

[RickHigginsHtbr]

I don't know how i ever missed this thread... :)
The GA - 100-ish.... i dunno of the exact speed... did it once on 202 playing with an old couple in a '63 vette, then slowed down on 88 goin to Albany when I saw a cop....
The T/A - between 95 - 100.... I think. I did it at atco in that car.
The Go Kart ('89 Horizon) - Whatever wrapping it around to 25 equals... 120? 125?
The '89 Mustang - Whatever wrapping it around back to 5 was... that was a couple of months before i bought it off my friend.

[99WhItEGaGt]

I had my 99 gagt going 117 then it didnt really cut out i think it just ran out of power that needle wasnt moving hardly at all

^ im in the process of getting my private license :D good fun.

113-115 then the motor kicks off....speed limiters ottabe outlawed

Give up it up for 85mph! :woot:
