Aside from the Cobalt winning the Time Attack with the second fastest time ever
I thought this was quite interesting...

I believe the '+' in Stage 2+ is the nitrous setup.

According to other press releases Stage 2 is supposed to be 241hp.

If you take 241hp / 283hp * 100 you get 85.15% which looks to me like a 14.85% drive train loss.

I'm going to go ahead and start believing that Stage 2 is going to give us 283hp at the crank... SWEET.

Also looks like our rev limiter will be raised to 6840 not 7000 as some have speculated.

 

WE discussed this already its not nitrous we guessed that it was a hybrid M62 S/C as it says in the discription. w/ nitrous it bumped it up to above 300

 

article in S3 magazine said 6700 red line

1 of the guys from GM , that was part of the time attack car told me that they were not raising the redline on the stage kits


even thought the grand am cup cars redline at 7000

 

I'm going to keep my fingers crossed and hope that M62 Hybrid means "Stock M62 with smaller pulley".

I think the numbers make sense. GM is saying 241hp, if that's at the wheels then a realistic drivetrain loss of 14-15% would put us at 283hp crank.

 

The article also said that they were using a smaller pulley than the stage 2 kit, But i really like the number of the raceattack, really surprise they beat the evo... by that much time
