Now I have a 1998 Pontiac Grand Prix GTP. I am keeping the lesabre but i might let it go for the right price. The supercharger is fast and the car has good road feel. The Quarter mile times are bone stock without the modifications. With the SLP exhaust i expect 10hp and with the K&N aircharger intake kit i expect a 13%increase,(But with supercharger around 15%) Adding this up i believe i will have close to 280hp. I am going to run the GTP on the dyno at tech school soon to verify the results.

6rossa's 1998 Pontiac Grand Prix

I have a 1989 Buick Lesabre T-type. It is white with a black interior. It has the GM 3800 V6. It has minor rust and is in fairly good condition. I have just installed a custom setup to hold a K&N High Flow air filter. I will have pictures soon. I estimate that the K&N will bumb the hp to 178. The car has only been in one car shows so far but there is a whole summer ahead and alot of work to be done.
The front facia/air dam is damaged so i am in the process of restoring it. I have fiberglass on the inside to create a stable base. I will then try to bondo the rest(hopefully the bondo will stick) I will then put many hours making it look as best as i can. I hope to have it done by july.

I don't have very many pictures at the moment but will have some soon.

hey nice GTP. Once you get the exhaust and intake done, go with a smaller pulley than dyno it. You'll see a big difference. Check out my GTP sometime, let me know what you think.

nice gtp. the new pcm helped a ton, i did also have a smaller pulley, intake, spark plugs and wires. i'm not sure much it will help a stock gtp but its worth it if your gunna do more upgrades. it does also take off the electronic speed limiter which is always fun. i got mine goin 145 haha.
