According to my calculations, with an ET of 12.510 and assuming a weight of 3440 for your car (including driver), you were laying down at LEAST 346.02 whp. Nice!
The car w/ a half tank of gas & me in it, (155 lb's) hit's about 3,220.
Oh yes, I do feel better about those low dyno #'s. Charles @ Auto Motion was pretty sure I had a bad tune and a few other people that know their stuff about these engine's & ECU's thought so too. But there is some disappointment too. I knew my car was pretty fast assuming what my G-tech #'s were (12.3/12.4) so I thought with a better ECU tune I would have a MONSTER. I had pretty well decided I was going to take my car to Jerry at LET and have him do a 3 to 4 pull dyno custom ECU tune. Jerry went down the track doing a data log with me twice and said the ECU could use a little adjustment - it was pulling the timing a bit, but it wasn't that bad. Jerry offered to send me a data logger for me to run on the car a few day's if I want, then send it back to him and he would put it in a file for me to send to RENNtech with my ECU to fine tune it a little better. But now after I winning the R/T trophy that included some dyno time, I may go ahead up to Chicago and get a custom tune.
