I dynoed the mark on sundayand this is with a built tranny with a 2800 stall that is supposed to be 10% more efficient. So can some one explain this to me, how to read this. It was about 75 out high humidity 93-octane gas, new filters and plugs and wire and tranny.

looks like your hp peaks at 5400 and stays up there and starts to fall off at 5700.torgue peak at 4700.and the air fuel mix is leaning down after 4400. thats the best i can do

WOW! that is BAD. how can you be 70-80 lower than stock with what you did?

Power train loss, every ones car dose the same yours is around 210 220 rwhp, you actually thought that was at the wheels, sorry man ford doesn't do things like that. Mine should be better than that though cuz of the more efficient stall. At least 10 % more. Typical is about 25-40 % loss. That is for automatic trans, 5 speeds have 15-30 % loss.

no drivetrain should show 40 percents loss, you should be looking at 20 percent loss max in a rwd car, 30 max in an awd car.

i have seen upwerd of 35-40 in some cars

an old awd like chev safari mini %50
or the jeep 40/60 awd
