My son and I took our cars to Sacramento Raceway today. My son has a C6Z06 with heads, cam, intake, exhaust, nitrous and a tune. It made 606RWHP on the motor and 768RWHP on a 150 shot. My son did not get his nitrous to come on. This was his first time to the track so he made several passes, gradually getting more aggressive. He ended up going 10.70's on the motor. My car ran 9.56 at 143 on the first pass with a 1.46 sixty foot which is about a tenth slower than normal. I got more aggressive with the launch on the next pass and the car did a 1.53 sixty foot. I let up early and ran 9.90. It was a warm day so I decided to watch my son instead of make more passes. This was the first full pass on a 200 shot (76 nitrous jet). The car will definitely run 9.40's on this tune.

 

Nice!
