While I know there are other differences, the main distinction between a turbo and a supercharger is that the former is exhaust powered, while the latter is driven my the engine directly. Would it not be possible to modify a turbo to be engine driven like a centrifugal blower? I know it would be tricky, but with used turbos plentiful at $20, and centrifugal blowers much more expensive, I'd be willing to give it a try.

What do you all think?

yeah, I think this is possible. Do a search, I'm sure I just saw something like this posted, and it may have some more solid answer for you.

I seem to recall that somebody here has attempted this already, but in the end it may have been easier, and more cost effective to just go out and buy a supercharger (or a turbo, can't remember which way they went)

It will be just as expensive to run a turbo setup in the longrun. The plumbing is whats hard. It will end up costing a lot of money to get the headers and the plumbing ran. However turbos are more efficient and do not take HP away from the engine to run them.

A roots or centrifugal (spelling?) supercharger will add a lot of hp but normally not as much as a turbo setup. Mainly because superchargers can be but usually aren't intercooled. Also they run off the drive-belt so that takes away a little horsepower.

Cheapest thing to do if you have a carbed or TBI car is to run a weiand 142 blower. It is alittle over 1300$. I work at advance and I can get one for 1100$ so I may do that soon I'm not sure.

I've been looking into the costs, and assuming I got a turbo/supercharger steup, seeing as I run a carb, I'd need one of those carb boxes that come in the Vortech and Paxton carb kits. The vortec carb box costs over $600 for the most basic example. I'm still going to look into it though, 'cos I've become addicted to speed.

Sorry if this post is incoherent, I'm afraid I'm quite drunk.

simply put, a turbo can more efficianetly make power due to it not requiering a direct drive. driving a turbo by a belt would in th esimplest way of looking at thing, but the same thing as a supercharger... you would still need to gear it up to turn the turbo much faster than the crank shaft, which is why supercharegrs pull power to make power...

read up on it, you'll see what im gettin at- im tryin to keep it simple for ya.
