I would not take a turbo car to the track. I don't like the throttle response. I don't like replacing turbos. I don't like how it muffles the engine symphony. I don't like how it generates massive heat.

Different strokes for different folks
And yet they have better fuel economy, more efficiency, don't require a taller hood, and have way more power potential.
You shouldn't be taking any boosted Corvette to the track anyway. The root style blowers especially are known for major heat soak issues.

Odds are pretty good the LT4 will make 750hp or so. A Rotrex is 3-5% more efficient so the peak power would be slightly higher. A turbo could probably make close to 800hp. Less than 50hp on top of 750hp going from Rotrex to turbo might be worth the tradeoffs to you, but not to me. In fact, at 750hp I wouldn't worry at all about getting more power, but rather HOW to make it in a more civilized manner.
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.
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.

Roots or Turbo?
