As for the superflow engine dyno they do have an SAE setting and we request it is used and our results seem to be within 1-2% ..

Also keep in mind a 3000lb roller can't create an equal a load esp on a 4000lb car .
Those are a little on the low side, but either way, your math is wrong. To correctly find the HP would be to DIVIDE 422 by .8x to find the loss. EXA) 422 / .85 (15% loss) would be ~497 hp.
