Thread: 2005 Grand Prix GTP Comp G

Didn't realize I never made a thread in here.

2005 Grand Prix GTP Comp G

Bought in April 2010

48K Miles (72,000 currently as of 5-5-2011)
Sunroof
HUD
But, cloth interior. Actually perfect since it is used as a family car. lol

Only Mod is a Motorsports Performance CAI


Plans:

3.4 pulley
Tune
Headers
CAI

YouTube - Walkaround the GTP with the S95



















































Bought a buffer shortly after getting the car......










Don't have an engine pic since installing the CAI



Vid after the CAI

YouTube - 2005 Comp G 0-80



Hope to get some more current pics soon.

Progress will be slow since this is our only car right now. Not trying to go too crazy with it. I would be happy with a consistent low 14 car. Maybe mid 13's if it wasn't the only car.


Here's my latest project I did a few weeks ago.



Pictars

Passenger Side








Process and Before/After sidebyside

I did 400, 800, 1000, 1500, and then 2000 grit wet sanding.

Then I used Prima Cut with a cutting pad. Then 3M Rubbing compound with a lighter pad. Then a coat of the urethane. I'm probably going to do a 2nd or 3rd coat once it dries 4 hours between each coat. Any suggestions on what grit to sand inbetween coats?

You can run a 3.4" pulley on these cars with those mods as long as it is tuned. Any smaller and you need an LQ4 MAF and 42.5# injectors to support it.

says who?

you run out of injector at 3.1 or so.

can't imagine requiring a new MAF until then either.

Either way, 3.4 with those mods wouldnt have much timing, which means higher EGT and more wear on the exhaust valve/seat.

hurray for accelerated wear!

Could still have a factory monster, but its unlikely.

3.8 is stock.

love the ride! wish I could get my lights looking that clean! glad to also see someone else with the same color car as me! jealous of the rims and sun roof though!
