As far as I know, when it comes to factory forced-induction, Corvettes have always shipped with superchargers. What are your thoughts on why GM has never embraced turbocharging for their factory-hopped-up Corvette offerings? Just curious.
Good question...nothing against it, but SC always felt “AMERICAN” and Turbo always seemed import...not sure why, but as others have said a Turbo looks to be on the horizon for Corvette (on th4 C8R at very least).
V8's with 90* angle are wide, and turbos usually sit on the side of an engine. Superchargers sit on top and it's easier to put a bump in the hood than widening the chassis.
Which is why you see turbo V6s and 4s, they're smaller blocks.

True, but some of the latest generation turbos/exhausts, such as the ones from Mercedes, are nestled in the valley between the heads so the packaging has become almost as compact as a SC. The leaked C8 CAD drawings depict this same configuration so we may well see this as one of the higher end C8 power plants.

Mercedes hot-valley configuration
I interpreted the question to be why no turbo in the current Chevy configuration, of course they can redesign the small block engine and change the engine compartment to fit it etc etc, but for the current package, and historical package, it's size IMO.

Wow that looks like it would put a LOT of heat into the heads and valve train!

At the C6 ZR1 reveal this very question was asked of Tom Watson. The response was there was insufficient room to accommodate the large diameter piping associated with turbocharging.

One of the main reasons is the immediate kick in the butt you get when you nail the throttle at low rpms. No Turbo Lag. Even small Turbos lag when the engine rpms are low. The SCs on the Z06 and ZR1 are there with gobs of torque from 1000 rpm on up. As somebody said HP is what counts and torque times rpm /5252 gets you HP so lots of torque is a lot more HP at low rpms. The LT4 in the Z06 has around 440 lb ft of torque at 1000 rpm. That is more than the peak torque on some engines.

Why Never Factory Turbo?
