There is a way to answer that question. smoke

Taking the net hp and multiplying it by the correction factor for that run gets you within 30-35hp of your dyno numbers.
I have to believe that “some” of that missing power is being lost with the exhaust system.

Did you try the 1/4 mile version of that calculator to see how the numbers compare?


This was our best mph run, short shifted first he said......Wallace suggests that to get your mph/hp the same @10.47ET it would need to be 130+, how many cars run 130+@10.4's, unless there 60 really sucks, ours was a 1.47 on that which sucks!!, guess the 2mph is in the exhaust?.
