To be losing 20+% at the wheels, you must be running a 9" rear end + an inefficient transmission, such as a C6 or maybe even a TH400.

Right the point is there is no way that 5th gen has only 12% loss .. Not even close . For instance Engine dynoed 402 ls motor made 607 at the crank on a superflow engine dyno . Installed in Corvette C5 [ I'm sure all who know whould agree 18% dr loss for 6spd car ] It made 514 whp on our mustang dyno .. that
We have done a large amount of testing as well as baseline runs on SAE Certed motors . Also back to my first post The 6l80e takes more power to turn like a 4l80e so less then a 4l60e
