640 rwhp= 753 crank/flywheel assuming 15% drivetrain loss.
710 crank/flywheel = 604 rwhp

With the Ricardo six-speed the car loses about 7% and change through the drivetrain. So I'm told by an engineer who worked heavily on the car... fantastically efficient.

I was assuming between 7-9% loss on the GT as well, although I have no way of confirming my assumption :wink
 
Everyone I have spoken with says 15% is a good number. So its one of those subjects with many different opinions.

Gtx1...

Regardless of the actual HP after the pulley and exhaust upgrades, at least 3 things are evident: the HP is north of 600 (probably well north for many cars), you need a light foot in first gear but not in second and beyond, and the sound is what one would expect from a car that looks like the GT...very serious but not obnoxious.
