Prob been on here before but I thought it was kinda neat although prob not very accurate.

Do the math for me, what's this thing claiming percentage wiseI've been lead to believe that a manual trans looses 12-15% to the rear wheels.
Are you considering the t5 "modern"?The problem with trying to convert rwhp to flywheel hp is that each drivetrain is different so you can't assume that all RWD manuals have a drivetrain loss of 15% and that all RWD automatics have a loss of 20%. Losses of 15-18% for manuals and 20-23% for automatics were probably true on older vehicles.
The drivetrain loss of modern RWD manuals is probably more like 10-12% with a loss of ~15-17% for automatics. FWD cars have a ~5% smaller loss because there's no driveshaft and the drivetrain is more compact.
I've created a calculator that'll estimate rwhp from vehicle "race" weight and 1/4 mile trap speed, and it's probably the most accurate that you'll find:

So what are you callin old, the good ole 3 on the tree??The T5 has a drivetrain loss of ~13% so it's pretty close to more modern trannies.
The T5 is definitly not modern. Mine is 25 years old. LOLAre you considering the t5 "modern"?

The above calculator has manual drive train loss at right around 17.5%, not 13%. According to that calculator, my 285rwhp works out to be 335.
