Mark --
Now I am really confused.

By my calculations, if I applied a 25% correction factor to my Mustang dyno numbers, I would get 529 rwhp x 100 / 75 = 705 flywheel hp which can't be right. Is your 25% correction factor unique to your Mustang dyno? Since my dyno guy could not give me a definitive correction factor, is there a way I can figure out what my flywheel hp is? Thanks for any insights you can provide.
