quick comment about GTP

[irishpenguin13]

just thought i'd share...kinda took me by surprise. went to the track today in florida and there was one of those new (i wanna say 04, or 05) GTP's there. old dude driving it, completely stock, ran a 13.8. blew my friggin mind. so there ya go.

[Hi-Po]

yea there pretty quick. But there wrong wheel drive.

[irishpenguin13]

also, i didnt even know that the supercharger was that loud.

[irishpenguin13]

is there a difference with those superchargers and the ones that they put on the cobras? or just same kind, different series?

[Mr. Luos]

Shouldn't have gone 13's stock.

If the S/C was that loud...sounds like there were mods.

[irishpenguin13]

IT WAS HAULIN' ASS! what you said is true though, i just went by what i saw in the engine bay at the staging lanes. just looked untouched and i didnt think that there were many performance parts for those cars. hmm...ya learn something new everyday. what times should they run?

[Hi-Po]

supercharger--I dont know about that..... i copied and pasted this from a diff. forum..

Opps, your right...

A quick Wiki search digs up its a 5.3L V-8, they call it a LS4.

The LS4 is a smaller 5.3 L (325 in³) version of the Generation IV block. Though it has the same displacement as the Vortec 5300 LH6, it differs in that it has an aluminum block rather than an iron one and it uses the same cylinder head as the Generation III LS6 engine. A version of this engine is adapted for transverse front-wheel drive application. In order to fit into the smaller engine compartments designed for V-6s, in the front-wheel drive Pontiac Grand Prix GXP, for instance, the LS4 engine block had to be shortened by one inch. Displacement on Demand is also used. Output of this version is 303 hp (226 kW) and 323 ft·lbf (438 N·m). Applications:

14's.
Mid I believe stock.

[Hi-Po]

not bad for whati it is.... good daily driver for sure.

[irishpenguin13]

damn straight. even though i think the 97-03's look better....'specially the coupes. i remember test driving an '02 GTP for my wife..the coolest thing was that little digital boost gauge.

[third_shift|studios]

i thought they were GXPs

[Hi-Po]

i thought they were GXPs

yes they are..... GXP replaced GTP.... GT is a supercharged 6 cylinder.

i'm badass

[Hi-Po]

i'm badass

sure...lol

[irishpenguin13]

i thought GXP and GTP were both still being made. am i wrong i guess?

[ZAPFOOL!!]

most likley pullied...I know when I but on my 4 pound pulley my eaton became a screaming bitch

yes

[irishpenguin13]

really? is it pretty safe to do? i mean, it doesnt hurt the motor or the supercharger does it?

[Hi-Po]

well..... its not gonna blow a rod out the block or nothin.... but anytime you up the boost its gonna havea slower life. Ive known a couple people with older GTP's that had them pullied etc... one of my Hi-Po instructers had one.... parts are way to expensive and your never gonna go fast. Just a DD.
