Roots or Turbo?

Turbos and DI seem to work very well together. However according to Keeks' info it looks like the FI applied to the C7 will be roots.

Turbo. All day long. Never was a fan of roots.

You shouldn't be taking any boosted Corvette to the track anyway. The root style blowers especially are known for major heat soak issues.

PD any day over a turbo for a street engine.

Turbos are fantastic for A to B cars. 1.4L turbo diesels make sense. Maybe that way the gas savings vs. other FI will be enough to service those turbines when they blow up or blow up something else.

Wasn't there a photo of an LT1 on a test stand wearing twin turbos that GM had pulled offline in a serious hurry.

Turbos. They don't have nearly the same paralytic drag, so they produce the more horsepowe at the same boost.
They do not "produce" heat. All of the heat of an engine is produced via combustion. Turbos will absorb heat and radiate it to some degree wherever they are located. Proper design and shielding will reduce this issue. They will heat the intake charge due to compression, but do so all forced induction conpressors, no matter how they are driven.
The only type of racing where turbos have not dominated roots or other engine driven compressors is drag racing.
Do they require a different style of driving? Yes, but any competent driver should be able to master it, if properly trained or they have a desire to learn.
Today's DCTs reduce one of the turbo's issues, coming off boost when lifting the throttle for shifting. No lift, no reduced boost.
Turbo's are a bit easier to intercool.
