Granted it's always amazing what the aftermarket industry comes up with but with as tight of an engine bay as the C8 the thermal management is going to be crazy. I think a TT kit is going to be really expensive and not very practical Vs a TVS/KB/Whipple kit. But with all the rumors of a TT Z06 car who knows.
That same thing has been said and disproven in many MR cars. Look at all the lambos, ferarris, and R8s with TT kits. No MR car has a lot of room in the bay.
