also i've heard that the lD9 has a base horsepower of 150..is this crack or wheel?

lolol sorry this just cracked me up.
but you can't expect to add those hp gains like thinking you'll get 30 hp from tb, intake mani, and exhaust. It doesn't work like that. If I were you, I'd just save till you had 2g's and buy the GM/eaton s/c kit and the only things you'll need to make it work are: the smaller 99+starter, larger fuel injectors, an afpr, and an s-afc. You can sell the gm s/c map sensor that comes with it, and the high impedence injectors, or find a used kit that just includes the blower, and do the rest yourself.

but also the other mods you're thinking of will add a lot more ponies than if you didn't have the blower.

so how much of a gain do u think i could expect from those things

[loud2kse]

i'd say 15ish. Mostly on the top end. Only one way to find out for sure tho. Do it and dyno it b4 and after.

[Matt95GT]

^I agree. 15 at the most, and that powerband will be shifted towards the top end.

[jayhawk]

Lets just say I had exhaust and a warm air intake on my old 2.4L GA, I think it was good for a whole 5-7 HP, if that.

ya boost is good with the LD9.

3400 is good for bolt ons, i gained 29 hp over stock at the crank with an intake and exhaust.

i was told that a simple cat back 2.25in exhaust will produce 10 whp???

Explain that printout, because I'm seeing rpm's in the 8500's! And something about 29 hp off of exhaust and intake sounds a little odd. I'm not calling BS just yet, I just want some explanation as to what I'm looking at. :)

[99blackSE]

There was signal interference from the tach, so the RPMs and torque ratings are screwy, but the hp ones are correct, and not bouncing around like the other 2. NeoBlue99SE seen similar gains over his stock ratings, remember an SE is only rated at 170 hp stock.

[dballz]

and a gt is only rated at 175... so I gained 24 hp from my intake, and catback???? I doubt it!!

[99blackSE]

and you're saying the dyno lies? Go ask NeoBlue for his dynosheet too, and go doubt him too. Read the mods list, youd be surprised what a good custom exhaust job can do.

[ChevelleSSLS6]

I'm a believer with the v6s+boltons, I went from crappy stock airbox, going from paper to kn yielded better response, and now I have a KN cone filter and it's better over 3000rpm, and I'm soon to buy a CAI made by a loyal forum member, Red99GAGT.

That is assuming we get enough serious buyers to make his effort worthwhile.

[Matt95GT]

Can we please curb the thread hijacking (this didn't start as a V6 dyno discussion) and pimping of group buys? Thanks.

J/K my photoshop skills are really good, notice the pen and the pencil. :roll2:

Lemme guess your intake consists of a chopped airbox and your exhaust is a muffler... Hey man, no need to get all pissy.

24/29 hp is a little hard to believe. Besides out of all the numbers you have circled there, none of them in corresponding rows are 29 apart...they are all about 50-60 difference...explain please.

I am pissy, I just got off of the clubgp boards (no offense to clubgp'ers)... and a great day topped it off. My apologies, its just that I remember people calling bs on NeoBlue too back when he said it, then he posted his sheet.

One column is wheel horspower and torque, the other crank.

Im not sure if its a dynojet or a mustang dyno, even if its a dynoyet (which i think are the ones that are slightly less accurate than the mustang dynos), thats still not gonna make up for the mysterious extra 15 hp im getting... If it is then all the readings on a dynojet are 50% higher than what they should be? I would find that hard to believe myself.

Why does it only make 147 to the wheels? Probably transmission problems; 75k miles and the previous owner lived city and did rush hour everyday, its probably got decreased efficiency since 1999.

Also I didn't mean a 29 hp gain at the crank over the whole power band, its just peak hp. Sorry for the inaccurate clarification.

It was done in 2nd gear indicated by the speed, because 3rd would hit the governor. I had one run done in 3rd, and it was showing similar numbers as well up until it hit the governor. Id have to dig for that sheet at home.

On Topic:

I don't know myself of too many people who run all bolt ons on the 2.4, and since it has smaller displacement (under the assumption bigger displacement = better power from bolt ons) it can rev higher, better for boost. With boost youd probably see those gains, maybe even greater, I can't tell you. Ask Matt95GT or Spy on GAGT or anyone else with a boosted 2.3 or 2.4 what they would think the gains would be with those mods with boost.

Edit: Looked at some of the descriptions on that site, and some of them say "with supporting mods" or something similar, so theres some of the explanation...

[dballz]

Actually I have the civic CAI for an intake, and SLP catback exhaust. I highly doubt that i have gained over 20 hp.

[99blackSE]

Don't doubt it... freak motor + right conditions can = bigger gains than what they say, and DS and SLP are well reputable companies. Can't see any reason as to they would overbias their ratings that much. Freakish motor + the rated gains = ~25 hp gain, (10 for the CAI at the crank, 12 for the exhaust)

[dballz]

???? lol i thought 10+12=22???? I know I graduated 6 years ago, but did i forget that much??? Freak motor maybe i could see this, but its called a freak for a reason. Its very RARE!!
