[No Groc Getter]

When we talk about RWHP vs. Flywheel HP I see 10 to 20 percent for drive train loss to get to a flywheel number on a 5-spd. Here is why I think that logic is flawed. Lets take my bone stock 93 LX wife driven coupe. 205 factory rated HP (or 225, thats another post). Using 20% loss through the drive train would equal 164 RWHP. Now throw in a 1300 HP Outlaw motor under the hood and use the same 20% conversion. That would equal a 260 hp loss and equal 1040 HP at the wheels. If you took this to its logical extreme that means that the stock motor would not even be able to turn the transmission much less move the car.

I'm not saying there is no drive train loss, I'm just saying the the loss is a fixed number and not dependant upon how much HP your motor makes.
