UTI had a invite and I was able to have 2 free pulls. Like stated you need to be in high and close to stall. First pull n/a with 406sbc was 525 hp. Car was pretty steady tied down. Next pull with N2O car made 770 hp and with loose front being tied by operator you would have thought the car would not move. The higher the rpm's went the higher the front end would rise. It was getting pretty scary and the kids started moving away.Anyway with those numbers it showed around 20 percent loss using et of car and BG calculator to calculate flywheel hp. 10.2 et n/a and 9.1 et on n2o.
