as to an estimated percentage loss in hp through the driveline, whats the percintage difference from flywheel hp to rwhp? is there a number you can assign to this? and do torque converters and other transmission mods change this?

sorry if this has been discussed many times on here, but the question popped in my head earlier so i knew where to ask

 

I think that it's around 15% with a good tranny... probalbly around 18 with stock...

Yes, tighter TC and tranny work helps this...
