sorry.. a eaton supercharger with pulley and tune and full exhaust WILL NOT come even close to 650 hp to the ground.. you need a twin screw supercharger (Kenne Bell or Whipple) pushing 20 psi to get those type of numbers..
I must agree.
I have recently raced a cobra doing 630 to the wheels with an eaton and hes done some serious work to get there.

Either way, it was exciting and I am sure he makes LOTS of power. Of course for the Nay-Sayers, power to weight comes into play. 3040 w/driver & 360whp (8.4) vs est 4200lbs w/passengers & 465whp (9) = Bascially a drivers race, with a slight advantage to myself.

The guy runs 630ish to the wheels with spray.
Its very doable. I have no clue what his boost is at.
He had always been at our dyno days before I raced him. Slowly climbing the ranks. He started at 410 and worked up fairly quickly.

My 03 did 380RWHP stock...with a 2.80 upper pulley, Bassani headers, Magnaflow x-pipe and exhaust, intake and Diablo flip chip I was right around 500RWHP and the stock Eaton was running out of steam. It's possible to put those numbers down with spray as the Cobra block is extremely stout...you would need to run about 100 shot on a direct port set up to put down that kind of power. Most would rather buy an aftermarket blower as they aren't very expensive and there's more room for growth. It's pretty easy to put down 600RWHP without pushing the limits of the blower with something like a KB.

A Cobra does not weigh 4,200 lbs....Google is your friend.
Again...the stock Eaton will not support anywhere close to that kind of power. The stock Eaton starts running out of steam around 15 psi (w/ aftermarket pulley) and with full exhaust, chip, intake, etc. the Cobra will put down around 500RWHP.
