my buddy has similar mods to a 2000 regal GS. he ran 9.60's in the 1/8th with nittos. and 10.06 on street tires. We are at about 3500 feet here. youll be fine.

 

My friend had an A4 LT1 camaro and lost a few times with a few GTP's

 

I love the detail.

 

Update!!!

Well we raced from roll and dig,

Dig he jumped a head a tiny bit, but once in 2nd i started kreeping up, by top of 3rd i was 2 cars ahead. On a roll I raped him because of the RPMs i could choose... one time he got a good jump on me but by the end I still had him.

All my friends were rooting for the GTP and some were pissed that they lost.. poor them lol. Now I know I need some brakes because I have pedal to the floor, no lock up or good stopping ability... I think I'm looking into Corvette brakes.

 

Glad you showed them. Some GTP owners are total jackasses and really need to be put in their place more often. Good job.
