When we put down 606 HP to the wheels, there is a drivetrain power loss of approximately 15%. The engine HP required to put down 606 Wheel HP calculates to 712 at the crankshaft. Since this run, we've turned it up, and now put down 639 WHP, which calcuates to 751 engine HP!

In round numbers, for engine build and turbo/fuel systems, about $10-12K.

Wow! How much would it cost to build this motor/turbo setup for a Cobalt?
