belt turbo
#1
#3
To me a supercharger is like a blower ... Which direct mounts between the carb and the intake ... This is a turbocharger that can be mounted (for example: in place of the a/c compressor) remotely and not run off the exhaust but off a belt from the crank ... Seems like this way it would be cooler running and not need an intercooler ...

A belt driven unit like you describe would be a centrifugal supercharger.
The "turbo" in turbocharger refers to the turbine driven by exhaust gases. Both sides are turbines, but the other side is the "charger" side, providing the pressurized air for the engine.
Turbochargers run to 100,000 rpms, so a cetrifugal supercharger has to have a gear set up to spin its turbine fast enough to make boost. Thus the comments by detractors here, as well as other info and links:

The heat removed by an intercooler is not only from the hot exhaust running the turbo, but mostly from compressing the air. A centrifugal supercharger would benefit from an intercooler almost as much as a turbocharger.
"Blower" is a slang term for supercharger, although the Roots boys designed theirs as a "blower" for blast furnaces.
Superchargers or Turbochargers can be located upstream of the carb for "blow-through", or under the carb. (also known as the "blow up" design as you have a supercharger full of air-fuel mixture--this is what blows the entire body off a funny car or launches the supercharger into orbit)
Google "belt driven supercharger" for dozens of examples and more info.

That would be a supercharger as previously mentioned, and the one that looks most like a turbo with a belt is the paxton NOVI
here is a link to them.

Tanx y'all ... I am now trying to make more room under my hood to accommodate one ... Project in order is:
1. remove bed ...
2. true dual exhaust to stacks centered behind cab ...
3. relocate batteries to inside frame rails ...
4. rake hood from stock on the front to a 4 inch rise at the rear ... (already mocked it with cardboard to check possible vision limiting) ...
I want a good airflow to reduce engine compartment heat ... I might even try to mould in a cowl induction when I raise the hood ... I miss being able to shut the hood and still have room to work ...

It can be as little as bolting on the components and the changes needed, which would have to do with your carb or efi, or it can be a complete rebuild if you want to run a lot of boost--you'll need to go to forged pistons and lower compression. If you bolt it on a stock engine, you won't be able to put much boost on top of stock compression, unless you have something like a 534 or 360 with low compression to begin with. (and then the fun begins with engines like those...) And if you overboost your old, tired stocker, you get to do the original install AND a rebuild!

I know my car runs at 8.5:1 Stock around 11 PSI. I would advise using a intercooler on most vehicles that have a SC or TC added to help keep the Charge air temps as low as possible.

What about H2O-Meth injection in lieu of an intercooler when running a centrifugal supercharger?
Most centrifugal superchargers have an internal 'transmission' in order to get them spinning fast enough to produce a noticeable amount of boost. I have seen some on Ebay that look homemade and use a pulley run directly off the crankshaft mounted to the compressor shaft of a turbo in an attempt at a centrifugal supercharger, but they look extremely inefficient. The 'charger pulley would have to be TINY in order to get that thing spinning fast enough to produce a usable amount of boost.

I use a hydramist on my miata with a supercharger. I'm not running high boost though (yet) since I haven't re-built the bottom end. The hydra is really easy to use and will auto-retard the timing if things start getting out of hand.

Another option to H2O + alchohol is Co2. It can be cheaper to run and produces a much colder air intake charge than the alcohol setup. DEI makes a pretty good setup. This one is actually a pretty good setup for just about any car, boosted or not as it does a really good job at lowering the intake temperature, which increases head pressure. And, it'll bolt into just about anything, won't screw with the computer, doesn't inject anything into the motor itself, and can be disconnected and removed easily if you need warranty work
