Just to let everyone know, you didn't build it and truth be known, I'm not upset with who did. I further understand that if you (or anyone else) wants to be competitive in a market you have to use the same "standards" as the competition does or you'll shrivel and die. Kudos to you (unlike the other forum builders) for being willing to openly discuss these issues that have positive and negative conentations...
Actually, if you were quoted flywheel hp, the 474 rwhp is just about right on the money. If you subscribe to the roughly 20% losses through the Cobra drivetrain, 474 rwhp equates to 592.5 fwhp.

Of course, if you were quoted 600 rwhp, ignore all of this senseless typing....
