turbo....

hey,
dont know if this is the place to post this up but meh oh well.
ive got a hold of a 100cc 6speed 2 stroke motorbike engine that im putting on my go kart that im making at school...
and my mate n i were drinkn 1 night then wondered if it was possible to turbo a 2 stroke engine of this size?
i know its not efi n u cant have it n shit... but yeah im interested in running a blow through carb setup.. im interested if it would be done?
 ive been told that im amde for even trying, ive done alot of research on google but found nothing much of use.
also would a charde turbo have trouble sppoling up even a little bit with i because iv got a video of a guy with a 5hp briggs motor with a garret turbo from a volvo bout the same size as the motor and it manages to get 4psi outa it, would it be possible to spool up something small?
well hope to hear from somebody on the matter
cheers

i suppose you could rig up a set of computer or similar fans and use that... although the power gains wouldnt be very noticable..
i dont think its possible because of the amount of shit 2 stroke exhaust has in it, oil and whatnot, talk about high maintenance!
plus, with a turbo on there, it restricts the exhaust flow, so with the power and exhaust strokes being in just one stroke, youll create backpressure while the turbo is not moving, and youll just end up forcing crap back into the cylinder, and thats not good...
i just say forget about it or use a ram flo system?

Supercharger? That wouldn't have the problem with the exhaust gasses fuckin' up the turbo.

as far as turbocharger choice goes, you could consider using a turbocharger of a kei car, they engines are generally very small capacity 600-900cc, and are probalby about the smallest turbo ur going to find.

Forced induction on a 2-stroke doesn't really work; any positive manifold pressure will cause most of the inlet charge to get blown straight out the exhaust. No valves you see...

Get a 4 stroke and then use a decent leaf blower for forced induction? Always been thinking about trying it out on one of my paddock bashers but I've been too lazy. Reckon it would work?

Should still work, the excess fuel air mix should burn before the turbine and spool the turbo even more if not should atleast give a nice flame out the pipe! i suggest if you try it you have the exhaust enter a large say 3inch pipe for X ammount of length to let any excess fuel burn before the turbo..
anyone got a spare victa engine and tiny turbo?

Couldnt this be countered by an appropriate tuned pipe to provide more back pressure? Which is how a 2 stroke stops the fuel from doin a straight through anyway.

dude it was a joke.... all the best for your turbo go kart.
dunno if this site will help at all but i found it ages ago. its an escort with a Honda CBR 900 RR engine that has been turbocharged.

Where are you going to put a tuned pipe with a bloody great turbine in the way?
Anyway the pressures generated by a tuned exhaust are tiny compared to the pressures generated by a spooled turbo.

There's also the fact that all turbo's I can think of require a pressurised oil feed and an oil drain. Not a lot of this with a 2 stroke.

well i was thinkn about using a datoo 1200 fuel pump n run thin oil, wouldnt the fuel pump be pressurized?? would it put pressure in the oil pressure thing, n have it run from the turbo back into like an oil catch.

from what ive read its probably better to use a smog pump as a supercharger rather than the turbo but the turbo would be fairly interesting.
