Gator Superchargers - need to stir the pot a bit

[fiat22turbo]

Things have been too quiet here, so to stir up some discussion, I present the following website:

http://www.gatorsuperchargers.net/photos/photos.htm

I'm thinking that I have enough worn out core turbo's and access to a lathe/milling machine to make this work. Might even make for an interesting product to perhaps sell.

I might even try it on the Girlfriend's Escort (hey what else you gonna do with an 89 Escort Pony? Can't hardly give the POS away )

Now discuss amongst yourselves.

Interesting....verrrrrrrrry interesting.

If you are to spin this thing, let's say, 50,000 RPM (barely half the speed a turbo spins), how big would the pulley on the crank be? If the one on the 'charger is 2" and your engine turns 5000 RPM, your overdrive ratio would have to be 10:1 which means you would need a 20" crank pulley. That's
bigger than the flywheel!

Hence the gear box built into the "center section" much like an off-road R/C Car gear box, multiple gears would be used to fix the ratio to something that would be usefull.

The Vortech blowers that the Mustang guys get all wet over are similar.

Not to say that it would be the most efficient system, its a fun engineering exercise none the less.

haha thats pretty damn cool..... someone get the plans and make one and stick it on a carbed omni or something. if i had the time and the car id do it in a heartbeat

I didn't see anything on that page about it having a gearbox. It looks like a straight-through design to me (which doesn't really get me too excited..)

A turbo compressor is made to spin at a different RPM than a super charger. Chances of getting any real air flow out of one of those is more slim. A reason they are HUGE compared to a turbo compressor per car

yeah and did you see where he was like you use a bigger turbo housing for a smaller engine?

A holset compressor setup off a Cummins on a 2.2 would be sweet. He has pictured a 2.2 compressor on one. The 2.2 Garret would be nice on a motor cycle though.

Did you read the bs about carbs being as good as fuel injection and just a waste of money. The whole thing is a BS spoof to get you to send him $200.

There is a reason why fuel injection is needed for turbos. To prevent detonation/overfueling at high boost. Also he admits that the thing is useless when he says it produces less heat because it is more efficient. It produces as much heat at the same boost as the turbo compressor it came from unless of course it does not produce any boost.

Thanks for your wonderfully technical post there dude. Perhaps you'd like to tell us how you really feel? Sheesh, dont' take it personally its just cars dude

Actually a properly tuned carb can be almost as good as EFI. the Key words are properly tuned and almost. A few years ago, the SCCA Trans-Am cars were using both carbs and EFI in the same series on the same motors (either Ford or Chevy V-8's). The carb motors seemed to make a little more power, but the EFI cars got better mileage. Figure that one out.

Basically, since a carburetor's fuel curves are based off of the amount of air flowing through them they can be pretty good at metering fuel. The issue with turbochargers and carbs is the non-linear delivery of the boost. Once they dump in the fuel from the power valve, carbs simply don't have much left to react to the change in load with. This is why they work pretty well with superchargers. Superchargers are a bit more linear with their power delivery, so it easier to tune the carb to this.

With that said, I prefer EFI to carbs any day. The tuning principles are the same though, even if the actual methods are different.

To be honest I wouldn't bother with his book or anything, I just thought that building a gearbox to drive the impeller side of a turbo might be worth playing with someday. Given the number of small but strong gears available in the local junk yards, etc I'd think it would be possible to come up with some parts to do it with.

the kind of gear increase needed to get any real boost from these compressors, or a Paxton is steep. They need to be of the highest quality to live. Last one I saw was a 5" gear turning a 1" gear. Thats allot for cheap crap.

I will be more than eager to buy your first one right after I see you make a pass in the 1/4 with that contraption and actually go faster than the exact same motor configuration without one installed
