ok this is the real xaivior ..my little cousin has been talking with you he has just moved back up to michigan so ill be the only one talking now ..sorry for the confusion

ok ..i was just looking at a yahoo blowthru group that i joined and they where talking to my cousin and the topic of belt driven turbo came up ...i found this interesting .. i have a small turbo sitting in my shop right now i am going to use as a guenni pig ..i think i can pull this off im good with gearing and im above all very patient i already have a design put together in my head of a way this might work but it will take time ..if it works ill find a larger turbo and use the same method (diffrent gearing of course) on it and see what happens ..guys i think i can do it so cross your fingers and we will see what comes about!

Ill keep you posted on my progress into this project

 

In essance a centrifugal supercharger is a "belt driven turbo". Read up on centrifugal superchargers and you will understand.

 

Look @ the map for the compressor that you are going to run & see where the sweet spot is going to be & devide that by the Max RPM your motor is going to spin & then you know what the step up ratio is going to be for the belt drive. My guess is that it is going to be somewhere about 8:1. now create your drive assy for it & now you have a Paxton (more or less).

Turbo compressor maps are in the 80,000 to 120,000 range. So at 5000 RPMs, to get 100,000 RPMs at the turbo, you'll need a 20:1 overdrive gearing/pulley ratio.

 

Has anyone ever made a turbo/supercharger? It could run off of a belt and exhaust. The belt would get It spinning at first, and exhaust gass would relieve the belt at higher rpms. This woud eliminate the lag of a turbo, and the power usage/belt slipping problems of a supercharger.

 

hmm that could work but it would be very difficult i think ..

 

I don't see it being feasable with a single power adder, but 2 might work. A very large turbo can be helped to spool up quicker with a smaller supercharger. Actually big boost applications use nitrous to do the same thing.

 

I agree ...but piggy backing them could get expensive i would think if thats what you are talkin about doing..then you would need 2 of them instead of just one i would go with the belt drive

 

just a thought but how do you plan on keeping the belt on the pulley when the super/turbo hits 100,000 rpm's.good idea however once it is spooled up it will be spinning 20x the crank pulley you are driving it off of. going with a step gearing might work but again all you would have is a supercharger. if you really wanna think it through use the normal design modify the shaft for a pulley but develop a clutch behind it(i.e. fan clutch) so that at a certain speed the clutch disengages letting the exhaust do the rest of the work...

just my .02

 

Man, talk about being behind the curve, a belt driven turbocharger compressor, what will they think of next?

Um, they’ve been doing it at Bonneville since at least the 40’s, and what do you think all the centrifugal superchargers are? All they are is a turbo style compressor attached to a step up gear drive (to turn 6000rpm into something that a turbo compressor could use) with a pulley on it. I know that at least the smaller Vortech blowers actually use common turbo compressors (I’ve seen a chart of which ones they are).

Of course, once you take the exhaust turbine off a turbocharger you’re just left with a supercharger anyway. That's what the name means: turbocharger = turbine + supercharger.
