Qtr mile or ENGINE dyno results

Looks like you are right - the wallace uses flywheel hp. It appears to use the Patrick Hale formula that also was used for the old Moroso speed slide. It's the same formula all the other internet hp to 1/4 calculators use, just a lot of them give the same output as the wallace when using rwhp, not fwhp.

I couldn't find anything definitive about if patrick hale built the formula for engine hp - but I'm sure that's the case.


Emil - what does Mike's duster trap? And what's the weight of the car with driver?
