05 Grand Prix GXP w/ LS4
#21
What's Up GXPeople, I made it over here as well, for all those inquiring about how the GXP runs at the track, my personal best so far is 13.811 @100.96 & 13.905 @100.57 (i've also run multiple 14.0's over 100mph) this car is 100% BONE STOCK !!!!!!!!! with 30psi in all four tires and 50lbs of stereo equip installed as well, weighed in with me in it at 3805 (or so) stock airbox, exhaust, EVERYTHING!!!! & a half tank!
We're limited with this car as no "real mods" are out there yet , most important being something to allow a hard launch at the track (Torque Management System uses the Traction Control to limit Torque Multiplication at very low speed) if it hooks up too well, it bogs down for a second. to see my slip (13.811) click:

Nice car! As long as they V-8s can be efficient they will be used in the cars too. DOD allows this to happen! I think these cars get almost 30 mpg HWY! Very nice/powerful sedan!

Well, depending on track prep, it can be tough to get a good launch. If the track is really prepped well, I had some trouble with the torque management system because it would reduce power if the wheels hooked too hard, causing it to kind of stutter. If the track isn't prepped as well, they'll start spinning pretty easily. There is a ton of low end torque, so the car launches fairly hard, and keeps pulling. The back end seems to squat quite a bit on launches, which could be a problem if the power increases.
