I went back to Lapeer Dragway today and met up with a few people. I took my Subaru WRX, my friend (Chris) took his '99 Pontiac Grand Prix GTP and we met up with another guy I know(Tyler) in his '01 powered '98 Mustang GT (who also had his brother, Joel with him). Tyler also had a friend (Dominic) in a black '99+ GT Stang that met up with us later. We had a blast. Temps were in the low '60s but we had to drive into a 15 mph wind. Chris and I left before the others, so I am not sure what their fast times were, but here is ours:

Chris - '99 GTP 2-door (he wanted to run it like he would on the street, so he left in the jack & spare, child car seat, etc...he was also trying to launch on regular radial tires). His best run was a 13.371 @ 104.64 mph.

Myself - Subaru WRX wagon, 2.0L boxer 4 cyl, 5-speed, AWD, mods are a turboback exhaust, Cobb Stage 2 tune, K&N air-filter with silencer removed, kartboy short shifter and a SpeedMonkey heat shield for the turbo itself. My best was a 13.449 @ 100.77 mph. I also ran a 13.485, a 13.662, a 13.703, a 13.737, a 13.762 and a 14.245 (missed 2nd gear).

Overall I was very pleased with these runs and we all had a great time. Hopefully Tyler will let me know what they ended up running (last I heard he had a best of around 13.80's though he was having a hard time hooking up).

 

13.37 with a Grand Prix!?

 

Watch out. I saw one a grand prix website about Turbochargers out now for the 3800 series. They even have a special plate that lets you take off the nose of the Eaton Supercharger and lets you run the turbo with the supercharger. They say on the site that the maximum horsepower you can get out of a GP with the Turbo kit is 690.

That is awesome! I wonder how much power the rest of the drivetrain can take.

 

 

Probably not too much power without stuff having to be customized. Grand Prix's are a good car except for mine.
