How much ET should a H & C + nitrous car pick up on.....
10.80 @ 125-6 on a nitrous tune (all motor)
1) 100 rwhp nitrous
2) 150 rwhp nitrous
3) 200 rwhp nitrous

 

Well I have not run that fast on the motor in anything yet, but I am very familier with n20. Here is my educated guess of a good setup with the right timing and a 11:1 AFR.

Motor....10.80@125
100shot....10.20@133
150shot....9.90@137
200shot...9.70@140

 

Not sure on your set-up, BUT my car

11.33 at 118 on motor only

100 shot: 1.45 60'; 10.70 at 125 (DA at about 2200' at our local track)
150 shot: 1.44 60'; 10.57 at 126 (DA at about 300' in Cordova IL)
200 shot: 1.35 60'; 10.08 at 132 (DA at about 600' at Thunder ShootOut)

My SS has heads/cam on stock bottom end, weight is about 3550lbs.
