The reason I say this is my 122.9 puts me at about 144.6 at the crank. 20% would equal 153.6, which I seriously doubt I'm getting. reaper4tour dynoed at 123 on an ATX Duratec...a 27.6% loss. Running an MTX, he likely would've gotten around 144.5, assuming 15% loss. As with anything, this isn't written in stone...just my thoughts after some observations. 125.2 FWHP - 126.5 FWTQ SVT exhaust (#4 of 9) - B&M FPR - Custom CAI - bnoon optimized TB #1 & 2 (beat that!!)

It doesn't really matter anyway... what good is horsepower that doesn't get to the wheels? 2000 Mercury Cougar V6 ATX. 16.0@87MPH, 155.0 FWHP

Thanks Demon Sounds about right. --- The reason the TQ loss is less is the dyno measures torque and then derives HP from it. So the HP loss is further skewed off of the initial driveline loss. 2000 SVT #674 - Check it out! Whoever coined the phrase; "If it ain't broke; don't fix it" ~ Just doesn't get it...
