Adding horsepower??

**TeKmInIbI** · 04-28-2011

Hi,
Im new here and have a couple questions.
First off, i own a 2001 GTP Supercharged.
It a 4door, and white in color.

What MINOR things can i do to add horsepower?
What MAJOR things can i do to add horsepower?

I already have a K&N Airfilter, but i want this car to be around 300-350 HP.
How do i go about doing this?
Chipping? New exhaust?
What are the things that need to be done FIRST before i do anything else?

Any help with this would be much appreciated!!

pulley drops

3.4 pulley setup with ALL supporting mods
Headers
1.9 roller rockers
A good tune (Knock free)

And you'll be at 300 HP.

Reading is free and proven to add 15hp.

knowledge of your car and motor is the best hp you can have. (a) your car will still run, (b) you learn to do it safely, (c) your car will still run. have fun modding away

For your power goals, I'd hazard a guess and say that turboing the car may actually end up being cheaper than trying to get that kind of power to the ground on the M90, but I could be wrong.

to the wheels maybe... a good tune on a 3.4 setup would net about 300 to the crank its really not that hard to get up to 300whp on the m90...

now much passed that go go gadget turbo for sure

headers, GOOD tune..., 3.4 pulley, plugs, new wires.. ported blower possibly. TB spacer never hurt.. anything past that and be ready to start fixin sh** when it falls apart..
Major? well.. I think of this car when I think of major.. lol but you'll need a very flexible budget.

YouTube - 9 second gtp oh and yeah thats a wheelie bar on a FWD.. just for traction purposes I'm sure..

TB spacer DOES hurt because you have to spend money on something that gains zero hp.

Also, those aren't wheelie bars, they are indeed traction bars. Plus, that video is OLD. Matt has since ran an 8.65 back in 2008 YouTube - World record 8.65 FWD 3800 GP, and to this day he hasn't been faster then that. Maybe this year he will.

they keep the cars weight from transfering off the front tires to the rear tires....

I even doubt it would be 300 to the crank...these cars don't have that much drivetrain loss. MAYBE 20% if your transmission is tired.

+1 traction bar sound better? lol it keeps the weight on the front end. I said when I think of a sweet GTP thats the one I think of? not the fastest.. lol? Matt's GTP is also bad*** your right lol

i'm still learning myself here, but i would look into intercooling, headers, etc first. i like doing things that do multiple things at once (reduce knock, increase gas mileage, etc.)
