Driver Jeremy Swenson took this 2001 Chevrolet C5 Corvette to a GLTC season championship win.

How did he do it? Luckily for you, he shared his formula for success with us–and now we’re sharing it with you.

230 hp.   Wow.  I wonder how he tunes to that.  Restrictor plate of some sort?

In reply to A 401 CJ :

That caught my attention as well, since he said it was because of the power to weight rules it must be a real featherweight.

Got a shot of them at COTA last year:

Most corvettes in GLTC (or all?) Are a DBW throttle body setup, with standalone ECU, or hacked Oem ECU, and use throttle angle as a means of detune.  As rpm increase, throttle angle drops, and they shoot for a flat power level.  We test most competitors on a chassis Dyno, most events

does that mean that they can have the mathematical limit of torque so long as HP never exceeds 230hp?
