Who Says You Cant Turbo A 2 Stroke?


Yes, it can be done, and done successfully. It has been done for many years on banshees which are reed inducted, twin cylinder, 2 strokes. The most hp made, is 180 @ 29psi. The motor is stock, no porting, just a turbo kit and on alcohol. A stock banshee makes 34hp so tell me that isnt successful!

However, it hasnt been done successfully on a SINGLE cylinder due to the pulse.

Oh yea, here is a video of my friends mild turbo banshee, running only 18psi of boost.

It runs 3.8s in 300ft sand drags at 90mph, where has a stock banshee is in the low 5s.

The biggest and baddest 350cc banshes that are naturally aspirated are only running 4.2s and 4.1s on their best days.

The turbo is consistent and successful, and very reliable.

here is another video of dans turbo bike going 85mph up oldsmobile hill. He has been the fastest at 89mph as well.

Oh yea, a turbo charged banshee also holds the record for the fastest trap speed by an atv during the pikes peak hill climb. His name is kevin gigot of GP Engineering. So tell me that isnt successful?

You can successfully turbo a reed inducted 2 stroke. Boostedboogie, you must have been riding the wrong ones?

i know they can be turboed. because they have reeds. OUR 2-stroke engines for the midbikes do NOT have reeds. they are built on a skirt design. this is why you can't turbo our stock engines. the smaller cag engines are reed-based engines.

The reason i posted this thread is simple. In the other thread you stated.

out of my experience, i have yet to see a 2-stroke reed-induced engine turbocharged successfully. when i say successfully, i mean actually pulling hard, making lots of power, and making lots of torque compared to stock. i've seen it done before and i've ridden a few reed 2-strokes that have been turbocharged, and all i've felt was the lack of backpressure which is REALLY needed on these engines. all the turbo serves is to push that needed backpressure out the exhaust... along with the unburnt fuel/air.

that reed-induced was a typo. i was going for that word where an engine isn't reed-based. that entire thread was mayhem, it would be easy for me to get things mixed up w/ each other.

piston port or case inducted works.

let me just say I've read alot about things like this and this is what I got:
Turbocharging a two stroke can be done but it is not as effective or as easy as turbocharging a four stroke.

like i said in other posts "has anybody thought about making an alternator that runs off the transmission, and powers and electric turbo and a fuel pump, so the faster you go the faster the fan spins, and the more the fuel pump pumps, that makes up for the whole "running lean and running rich" situation and...because of the electric fan, their wud be no cooling problems... i have created a system were as the electric alternator spins, the fan spins, but i havent got a hold of a small enough fuel pump" but i have been looking at laboratory liquid pumps they looks perfect for this project
