Awhile back several people were posting about making a homemade Super-charger by removing the exhaust side of a Turbo and replacing it with a pulley. (And how it would fit neatly in the A/C mount, etc.) The problem is that a turbo winds up to such hi speed, that to get that much boost you’d need some kind of gear-box to drive it off a belt. However, I would like to point out that an oversize donor turbo might work. Justabout every big truck you see on the road has a big honkn turbo under d hood – some engines making 600+ H.p. The big trucks have their own junkyards & turbo repair shops – a big truck turbo with a damaged exhaust impeller shouldn't be that expensive.
Just a thought for the Crazy Ideas Dept.

 

Aye, but those compressors aren't designed for detailed low boost applications.. they're designed to pump 30 PSI into a 12 litre motor at idle. A friend of mine who worked as a mechanic for Swift and I were discussing this at Denny's a few weeks ago and came to the conclusion that tuning the drive system would be hell, and getting it to produce a broad low-boost range would be next to impossible.

NOTE -------------
As long as you're not using my engine as fodder, though, feel free to prove me wrong

 

I was considering using a whiple charger off any doner v8 v6 v4 or what ever it came cheap off of, you only need to mount it for a pully and the AC is a good spot. Then all you need to do is make some duct work so the air comming out stays compresses and into the TB.

I can see a car now with one of them offset hoodscoops and the whiple charger would have a nice flat top for a big air cleaner and you could run a ram air/ hood scoop into it for a tad more boost.

NOw it may be best too move the alt and other stuff too the ac side of the motor, put the whiple on that side so an offset scoop would not block your view outside.

The cut a turbo idea would work but you would need a real real real small pully so it would turn fast enough then it might spin too fast once your moving and or belt slip could be a problem.


I still think a turbo installed after the y pipe with no blow off valve or intercooler [ cause it would get plenty of air flow around it] and you should get a good 5-10 psi all the time.

 

has anyone considered the twin eaton or even a single eaton similar to saturn5's setup?

 

ok, well first off you do not want gobs of PSI going through that tiny motor.

The PSI controller will HAVE to be a turbo style BOV(Blow off Valve) Second, turbos spin normally 'round 20-25K Rpms. So you will need a master pully, on the crank al least 4 times the size of that on the turbo backing. That way teh turbo will spin 4X the speed of the motor. Yu can "rough in" PSI limits by switching the pullies around, and then fine tune them with the BOV.

 

Maybe you already read this on the Power adder board. But I posted this several months ago, and here was the response.

Sounds like the exact same idea I was having a few months ago.

 

Joe_L- thanks for posting that thread, I'm impressed with your bud's job. How big is that 'charger- what did it come off of?

TechSmurf- (on using your car) 'IF' I were to tackle a project like this, I'd find an old S10 or Blazer - maybe remove the intire front cap & add lots of roll bars and a scatter shield, to use as a test bed - to try to re-engineer a motor is tough enough, even the auto manufacters don't try to do it all in one deft swoop.

V6sucker- Yea, I was pretty much thinking you'd have to use a Blow off Valve, sometimes called a waste gate. These truck turbos are 2 or 3 times larger than a car turbo.

 

I didn't know you all were engineers lol j/k

Anyhow it seems like a good concept but i don't think anybody wants to be the gin-e-pig.

All you guys gotta do is get a custom pass. side manifold for a turbo and get a junkyard turbocharger and intercooler.

I could get you a stainless header with the flange you need for a real good price

 

What $500?..... STOP YOUR ADVERTISING!

 

Sorry it was just a suggestion over trying to re-invent the supercharger

And $500 is a little steep. PM me if anyone wants a price quote.
