I thought turbos are exhaust driven, superchargers belt driven.

Show us an example.

An old friend of mine runs an ATI setup on his 69 GTO. 421 (or 428 - I forget), blow thru carb setup w/6 psi of boost, stock iron heads, unknown (to me) cam, 2500 stall, 9" rear, 3.00 gear, th350, 28" tall tires, 6k redline, full interior street driven not optimised for the dragstrip and he has to use a throttle stop to keep it below 11.50 since it has no cage (60' time in the 1.6 - 1.7 range).

Early on he had some tuning issues and burned up 3 pistons (lean on the top end) but got it all sorted out and the car has been very reliable since then.

That's a procharger.....a centrifugal supercharger.
Not a belt driven turbo....they work well....drove a fox body deep into the 12's with procharger, gears and exhaust and nothing more.

In definition a turbocharger is powered by a turbine that is driven by the engine's exhaust gas

And in definition a supercharger is mechanically connected to the engine's crankshaft by means of a belt or gear.

Now what your talking about is a centrifugal supercharger. Some people see it simply as a belt driven turbo because basically it is. Like a Turbo it's also powered by a turbine but instead of being powered by the engines exhaust it's connected to the engine's crankshaft by means of a belt or gear.

I put a Centrifugal on my old 99GT Stang, here's a few pic's

I honestly didn't know what a Pro-charger was. Searched and found this:

ProCharger Carbureted Chevy Systems

I know it's a procharger, just assuming that's what Gary was really asking about since I have never heard of a belt driven turbo.......

Gary these things with a centrifugal compressor like the Procharger or turbo-charger are both examples of using a centrifugal impeller to generate air flow with pressure. How that compressor is driven gets into the naming.

You vacuum cleaner uses a centrifugal compressor powered by an electric motor. The Pro-Charger takes its power from the crankshaft like a classic GM Roots blower using a belt to make the coupling. The "turbo" powers its centrifugal compressor by ducting hot exhaust gases into a turbine on a shaft common with the compressor.

Quite literally a turbo jet engine is little more than a turbo-charger with a combustion chamber where the piston engine would have been. In fact a turbo charger can be used to make a turbo jet engine, it just doesn't last long doing that because of the temperatures of jet exhaust against the turbine.

I do know about (somewhat) about turbo's.Yrs ago I did the wrenching on a friends ET GN.It was the belt driven part I wasn't sure about at first.Do think it is neat idea.Maybe doesn't take as much to drive them as a roots.

A supercharger is any device that pressurizes the air intake to above atmospheric pressure. Both superchargers and turbochargers as they are called today do the same thing. As a fact, the term "turbocharger" is a shortened version of its official and original name "turbo-supercharger" Designed and most valuable on WW2 planes! Whether a belt drives the turbines impeller or electricity or the exhaust of an engine its still a turbo-supercharger

Sorry in my last post that should read:

I'm a supercharger nut, I've had 8 Supercharged Vehicles now and have used @12 different types and sizes of Roots & Twin Screw Superchargers. Once you experience the absolute INSTANT power you will be hooked for life

What makes a Centrifugal Supercharger a little different and a great choice (especially as an add on to a vehicle that wasnt made for a supercharger).
IS they have small ones that you wont even know are there under normal driving yet they will increased power and maintain OR BETTER you MPG.
And when you stomp it to the floor the difference in power is just mind blowing. For example my old 99GT had a pathetic 235/270 to the rear wheels and when I put the smallest Procharger made on it (P-1SC at 8-9 lbs) it went to 385/385 rear wheel. Thats @ a 60% increased in power and I installed the entire mess one Sat all by myself. They also offer units like the F-2 at 23 lbs that will increase your power over 200%, (but you better be built for it). And yes they are clearly less stress on the motor that a Roots or Twin Screw
