So the question becomes... just what fraction of a PSI is required?
If it is below about 4inches of water column you might have some vague chance.
It will come back to a hassle worth doing is worth doing well... that is 6PSI?
I bet at an idle you could boost reasonably OK but once you get to 100 cfm you must earn that boost.
This is were you need a big frikken blower, an engine on a dyno. And a Variable AC Drive to run the blower where ever u want it. Or even a a damper to waste gate and control the boost. And a manometer to track what boost is needed.
I know, I know, should have let it die. :LOL:Quote:

G'nite, Mark
Supercharging two strokes by using another cylinder or piston is as old as two stroke motors.It's been done lots of times and many racing two strokes of the thirties were set up like that,But if you want to see the ultimate blown 2 stroke,haver a look at diesel locomotive,All the older EMD's ( a GM product) have engines ranging from 1500 HP V8's up to 6000HP V16's ,all 2 stroke ,all blown by the biggest GM blowers you'll ever see!!!
Get a cheap turbo and a air box ,mount the turbo under the wheel well like a cold air intake , use compressed air to run the turbo and use it like u would N2o,all u need special is the little flapper thingy in the air tract so when it comes under pressure it closes off the outside air and uses the turbo air untill pressure drops back off and then the flapper releases and u go back to the outside air!!!!!!! sorta a sleeper setup!!!!!and if u figure how little air pressure the exaust actually puts out u can see that compressed air will give u much much more than a normal motor can handle:whacked: This would be a really hot setup if u used it in say cali where N2o is illegal on the street.All I can say is hold on because this isnt going to come on slowly like a turbo normally spools ,this thing will go till u blow the head gaskett off or limit the air with a regulator.This is experimental and as with exsperiments it could get outa hand pretty quickly I would be thinkin safety safety safety!!!!!!!!I think this will fall in the catagory of home brew for u and actually work!!!!Like most things home brewed ,there is almost always a way to do this more easily ,and more efficiently,but probably not any cheaper.Just though I would give a idea to cobble on that would produce some impressive gains for all that effort.U will see this applied to alot of turbo cars here soon,normal turbo installations using compressed air to spool the turbo on the line and leave under full boost :eek:
your real name is "Rube Goldberg"? right?
shawn, that's interesting that you would bring that up. Back in the 60's, there was a company called Turbonetics that had a product like that. They used a charge that could be replaced to spool up a compressor wheel. It was sort of like a stick of dynamite, but it burned much slower and the gases released provided the pressure to spool up the wheel. They even had a unit that bolted into the third member of the differential and drove the ring gear. You can find their ads in some of the old Hot Rod magazines.
Two last words . . . JATO Bottle . . . .
That is all . . .
JATO ........ now wer're talkin'............:DQuote:

LOX too...................:LOL:
Shawn don't you run into the problem with onagain offagain boost of mixture control ?!?!?! You'd need computer controlled fuel injection that includes anticipation. Or the engine goes psychotically lean the instant you hit the button.
Ahhh, remember Mel Gibson's ride in road warrior? The clutched blower? Musta had a fuel injection!
Hey Guys this was a neat thread and I appreciate all that was put into it. Alot of fun. Streets and I are going to put together a mean SB with either a 6-71 or 8-71 blower. Now my 305 has turned 102 guess what it will do now with a bigger engine and a REAL BLOWER!!!!:D:D:D
Tell Streets 'ya wanna' put EFI on top o' the huffer. Just to see what reaction you get. HEHEHE:LOL: :LOL: :LOL:Quote:

If you ever wondered where the "roots" blower came from, here is a little history:

Pro 70 Already did and he wouldn't speak to me for a week:D:D
I thought the air operated JATO turbo was a fine cobblin project:HMMM: :LOL: :LOL: :LOL:
"Tell Streets 'ya wanna' put EFI on top o' the huffer. Just to see what reaction you get. HEHEHE"
You just KNOW he's gonna insist on 2 Predators :LOL:
Roots-type blowers are used for gas meters also, only the process is backwards. The gas turns the rotors, which turns the gears, which turns an index or counters. I've seen a Roots meter the size of a small Buick. They can also be used as vacuum pumps. We used to say "if they'll blow, they'll suck."
Please refer to the second post.....
NO SUCKING ALLOWED!
