alright guys, i have a few questions about getting a little more power out of my 2001 GTP. right now the car is completely stock. so it has 240 hp, 280 ft-lbs torque, as you all know. it runs 0-60 in about 6.5, as far as the rest goes, i don't know because i haven't done any testing with it. what i am wanting to do is increase the hp, and TORQUE to get it to run a little faster, to be able to back up its looks a little better. i'm not the most mechanically inclined person, i just have the general knowledge about it.
question: how much smaller of a pulley can i put on, without putting to much pressure on the engine and supercharger. and how do i know what the engine and supercharger handle?
so if i wanted to put say a 3.5" or a 3.4" pulley on it, would adding a borla exhaust and cold air intake be enough. or would i also need to upgrade the headers? also a few other questions, what about putting in a performace chip( i dont actually know how to do that or where it goes, but i've heard of people doing that to get a little more power.) another question, i've read some other posts about exhaust systems, and they were talking about a downpipe and ubend, what is that? and ive seen post about scanning for KR, what is KR?
so overall would adding:
borla exhaust
cold air intake
header upgrade
performance chip(maybe)
be enough to handle a 3.4 or 3.5" pully.
as i said, all i'm wanting to do is add a little more power to get it closer to 300 hp/tq and closer to under 6 second 0-60. i just want it to be able to back up its looks a little better (i will be adding a ram air hood, new wheels, chrome grill, and a new paint job with effects, have already put LED taillamps, and clear corner lights and new fogs). right now it has 72000 miles on it. its in pretty good shape, haven't had any mechanical problems since i got it with 50k on it. i do all the routing maintenance myself, and i dont mash the pedal all the time(just half the time, LOL. and when im in the front of the line). i dont want to put too much strain/pressure on the engine, and i dont have the money to upgrade everything, but i dont want to anyway. just a little more power is all i need. ANY comments or questions, and for sure any suggestions are welcome. THANKs for your time.
also, to anyone who has done exhaust system, what have you done? im looking for a deeper and louder sound, but not like a rice wagon cherry bomb
and does the downpipe go in place of the u-bend?
