why are v8 are generally supercharged and not turbocharged?

Availability, plus the V8s don't rev that high, so you only get boost for around 2k rpms, vs from idle to redline with a SC.

It depend of philosophy of country where you live.In USA, you use SC against in Europe, we prefer TC.
I think it's more easier to install and tune a SC instead install a TC.

TC sounds better! LOL.

I think its because it cost alot more for a turbocharged V8 then a supercharged V8.

Plus, we are all about throttle response, screw spooling.

Ever heard of a TWIN TURBO Corvette or Mercedes?

People do it.. but it's a bit more expensive and 2 turbo's get costly.. and turbo manifolds... and intercooler's.. and fuel managment etc...

45K for the TT kit for a corvette

54k for a corvette, lol.

Turbos are catching on, and the technology is old. V8s do rev high, they just don't have to rev high to make power. Plus, the most popular type of supercharger on the planet, the centrifugal, will spool up slowly as well. In fact, with proper turbo planning (getting the correct size turbine and compression map), a turbo will have no real lag at all. Just look at the new line of Audi turbos and VW and you will see that peak torque arrives at 1900rpms for some cars. Try that with a supercharger.

thats what my brother says, turbines are being made of very light ceramics that pick up speed extremely fast.

Very interesting

5K for mine. There are quite a lot of turboed vettes out there...single and twin. It's more expensive mainly because tuning is a real pain. If you've got a good performance shop close that knows how to install them, turbos are the way to go. They hit peak boost sooner, so the power really comes on lower in the rpm range. Mine starts hitting boost at one or two psi at just over 2000 rpm. Some turbos will be hitting their peak by then.

I think most Americans prefer the SC.
It isn't that their are not any TT v8 engines...it's more of a "why TT?".

You see more TT applications with the smaller engined cars....and it is more typically a "ricer" add-on.
Plus...in TT you are talking a much more involved process. I think someone here already said something along those lines.

87-93 Mustang Supercharged kits start @ $1,799

Mustang best bang for the buck

Lots of TT V8s if you look in the right places. I can think of quite a few TT Corvettes. Ligenfelter, TTi, Extreme, and Halltech all make TT kits for the C5 and Rob Raymer is working on one right now. The main reason there are more SC vettes than TT is the cost. That's why mine isn't TT. That, and like you said, tuning is a real pain.
