He hand builds prototypes as they are being designed. He's been on this Corvette project from day one. They are having huge issues putting big power in the C8 as the floor pans twist.

So the c8 has what according to the article... 520 something to the wheels.

A quick math check reveals that's an estimated 656 hp and 606 lb-ft of torque at the crank if we assume a 15-percent drivetrain loss c7 stingray was 455 at the crank...

Rod Posted October 21, 2019 Author Share Posted October 21, 2019 A mustang dyno is one of the best dynos for tuning, but they aren’t the best for comparing hp because you can manipulate the readings with user inputs. Properly set they’ll read low, improperly set they’ll read high a dynojet is better for comparing numbers. Way less to manipulate. Quote Link to comment Share on other sites More sharing options...

That’s ridiculous. My “09 3L 6 cylinder bmw was close to that with no bolt ons parts. Pathetic. No wonder why I won’t own an American car.
