Need a Good Website Calculator for ET to HP

Gotcha. Sorry, forgot to mention I get almost 0 slip at the wheels, hot drag radials, 2500 stall, I know it is slight, built high performance trans, manual shift valve body, no missed gears, very limited tire slip, 8-3/4 built to race. 3" Exhaust out the back minimal mufflers. And 0 bog, hooks straight up.
