Gator Supercharger

I see he finally woke up and admitted it was a supercharger. For a while there, he was a complete dick to anyone that said that it is a supercharger. He kept calling it a "belt driven turbocharger." @_@

At one point he kept bitching about how he had so much documentation, stacks and stacks of it. So I said i'd be willing to help him scan it all. Next thing I know there is a post to the board about 'forum members' wanting to steal his info and drive him out of business blah blah blah. The guy is a quack IMO.

Interesting idea, but you are trading the complexity of additional exhaust plumbing for the complexity of a belt drive.

In the end, it's just a belt driven centrifugal supercharger.

I have to think that this could be a cheap way to boost a small engine. You'd really have to overdrive this thing to 30-40k to get significant boost and belt slippage will be an issue at those speeds, but it's got possibilities.
 
I've been thinking about useing the constant velocity drive system off of a Honda Elite 80 scooter as the drive system for a supercharger. The only problem is that I can't seem to make it work. :(
My thought was to get the supercharger upto speed very fast and then just use an electronicaly controlled waste gate to control it.

One idea I had that will work is to use the 2 speed transmission from a Hondamatic equipt motocycle. The transmission would allow the supercharger to spool up quick and then shift allowing the engine revs to climb with out overspeeding the supercharger.
Problem: To big, and complex, that and the fact that the little Hondamatics are getting hard to find.

Then there is the hydrostatic drive supercharger. Basically it's a pressure washer pump that is belt driven off the engine and goes to a hydraulic motor that is powering the supercharger. boost is controlled by a cheap hydrostatic unit off a riding lawn mower. It will share it's oil with the engine via an expanded oil pan, about 9 quarts.
Will it work? Probably not, but at least I keep trying.

Dick isn't the only Nut out there. I see one in the mirror everyday! :lol:

Anyone else think it looks like a turbocharger compressor section mounted to a gear reduction unit and bracket so it can be belt driven off the crank?

It seems to be simple but hardly what I would call revolutionary.

It would have to have a fairly steep gear reduction to spin up to 50,000 rpm to provide the boost a conventional turbo does.
 
It is a turbo compressor. That's the point, they are easy to find.

I see major bearing problems. The life of a bearing is directly related to speed. Bearing selection would be critical and I see a sealed bearing failing very quickly at 30k rpm.
 
Well I'm taking the wait and see approch.
I would really like to see it work. It would be a big plus for all of us.

I agree and disagree with your statement.

A T3 turbo is designed to routinely operate at 48k-60k while pumpin out anywhere from 10-26 lbs of boost or more...but it doesnt do this at a sustained continous rate like a supercharger does.

On the other hand the turbo compressor side in this setup isnt sitting against the red hot exhaust side of the turbo so maybe it runs cooler?
 
It's just a poor boy version of a Powerdyne.
The Powerdyne also uses sealed bearings and a drive belt.

The nice thing about the Gator is that the bearings are about $10 and they would be easy to change.
I've got an old turbo off of a 3406 Cat diesel. I might have to try this some day.

To add a idea to the list.

I read last year about a U.K. company which has taken the basic design of computer drive motors and redigned them to run turbo's. These little sucker's will spin upto 100K rpm. I didn't keep the link for the company but if you look hard enough it's out there.

But the T03 bearing body is lubed by recirculating engine oil. These appear to be ordinary grease lubed industrial flanged cartridge bearings. They work fine at 1750 RPM in an electric motor powered driveline and would be OK at 3500 RPM or so for a high speed motor. Overdrive them by more than an order of magnitude and things may get pretty hot pretty quickly.
