Thread: I'm new to GPForums

Hey everyone, im craig andi drive a 99 gtp, im getting headers, a 3.3 pulley, 3 inch DP, rebuilt supercharger with high speed bearings, a full exhaust and CAI, wit a dhp pcm, anyone give me a ball park estimate on the power it will produce?

Yea, its crazy the whole engine came out a friends car and idk what all he has done with it exactly but i know what i listed, and the pulley throws absoloutely no KR surprisingly.. and he told me that when he took it to the strip before he put the 3.3 on he ran a 13.2 with the stock pulley, so its pretty decent, no pinks all out winner, but i need a daily driver not a weekend warrior. what do you think it throws at the crank with 230 FWHP?

well drivetrain loss is ~20% so 230* 1/.80 = 287.5.

All rough numbers.

I'm trading off my GTP already... For of course another GTP, why go away from something so great. But the mods i was going to put on my car are on the car im getting, its got OBX headers, Solid Motor mounts, a full 3 inch maganaflow exhaust, DHP PCM, Wizarid intake, zzp shift kit, No overdrive.. lol.. i do believe its got an msd ignition system but dont hold me to that, 3.3 pulley, and im not positive of what else, but while he was at UTI they rent out a drag strip a few times every year and he ran a 13.2 with the stock pulley on it.. but compared to the 98 GTP he ran against he got his ass hammered, the car looked stock but it had a Whipple on it and alot of other stuff, i think he said it ran in the 11's

ALSO!! it only gets like 18-20 mpg, can anyone tell me why? mine gets around 32 on the highway and this ones all around better condition! any help would be appreciated!!!

MSD coils are worse than the stock ones, It can't be a 3" magnaflow system since they only make a 2.5", if its got no overdrive, that'd explain the mileage issue as well as suggest that the tranny might have seen better days... Be prepared to buy one in the future.

My bad, its got magnaflow mufflers, though they dont muffle much.. its got a 3 inch system that he built back to the mufflers, and we are taking the tranny out of my current gtp and putting it in this one, but it was getting gas mileage like that when the overdrive still worked...
