Detuning?
I know it's early and not much info but how far can this SC motor be de-tuned you think?
In order to stay in my current class, I would need an 8:1 power to weight ratio (including driver). Basically let's say the car puts 590 to the rear. Could it be de-tuned to 460 without damaging anything?

And less weight = faster cornering
even if the power:weight is the same as a heavier car.

What are you allowed to do detuning wise, is it an air restrictor only?
If not, the Z07 should be the best base. Take out the supercharger entirely. What's left will basically be a most reliable engine option ever. A normally aspired LT4 should last far more than the LT1 counterpart.

More power will make it to the ground via lighter moving parts: crank pulley, CF drive shaft, CF rotors.
Then there is the stuff that will really make the car faster, like 335 section tires, aero, and tireless CCB brakes.
The Z07 looks like a no-brainer to me.

I read where the LT4 has 3 modes...V4, V8, and V8 with supercharger...no where did I read these modes are user selectable. I suspect this is a grand way of saying that developing boost when AFM is in V4 makes not sense, and when in V8 mode if you stick your foot in it the boost will kick in.

What class are you running? TT2? I just can't see you being that competitive trying to detune a Z07. Why not do TT1?
