Ck my gallery.

Bottom line is that it will help you a little over a complete stock engine with a muffler.

For really max HP, go with a Brett Moorer, Bruce Bennett engine.

Or for a really high HP heli, GO ELECTRIC!!

no, really!

The fact is, you cannot supercharge a two stroke on the intake side. The reason for this is that the intake port closes BEFORE the exaust port, so any extra air you pump in while the intake is still open, easily escapes before the exaust closes. '
All it really does is lean the engine, which makes you think you are getting more power. You can install one of these and the motor will have more power for the same needle setting its true, but the only reason for that is that its a leaner mix... bad for the engine.

Then youll eventually end up blowing your piston. In order to run one of these you will have to pump more fuel to the engine. Or drill out the piston and make your own, which i highly doubt would be worth it.

You can supercharge 2 stroke engines. Since that’s what engine manufacturers use to do especially with diesel. And they do make an improvement, but with tiny engines smaller improvements. I have seen RB superchargers on RC trucks like the T-Maxx and Savage and the numbers before and after installation with richer needle settings after. But the improvements are not worth the 200 bucks

for those that don't think about it,, rather 2 stroke or 4 a carb inducted/induction motor does NOT fill full of air when running, that is 1 reason why the older OS 50 gained power with the larger 60L carb, the motor is simple taking in more air,, so with that a blower will work on a 2 stroke,, the blower in question in the link above is simply a piece of junk IMO, if it was made "right" it would work, up to a point,,

plus, do a net search for turbo charged snowmobiles, you can get a good 100% boost in power for your snowmobile with a turbo !!

the two stroke in a snowmobile is a whole lot different than the 2 stroke in an RC heli... apples to oranges....

Dacaur,, the snowmobile motors I saw with turbos on them were very much the same as our glow motors, meaning they were not piston induction motors, yet others were piston induction motors,,

""so any extra air you pump in while the intake is still open, easily escapes before the exaust closes"",,,

you have forgot about the transfer ports, the transfer ports do not open until the exhaust port is around half open, this will allow air to be forced into the crank,,


as I said, when a 2-stroke is running it's crank-case does not fill full with air, ask any good 2-stroke motor builder,,

think about this,

1) what does any carb do, it adjust how much air goes in the motor,,

2) your motor is running and the carb barrel is only half open,

3) you instantly add a blower,

question, with the barrel only half open is that motor going to use that extra air the blower is pushing ??,, yes !!

Looks like a novelty item. I've seen nitro cars and trucks with miniature NX kits (nitrous oxide) that looks exactly like the real things with chrome tanks and everything. When you think about it, it SHOULD work for drag racing. If it works, you can even get Honda Si stickers that should add even more HP...apparently, it works for those rice burners!

just add more stickers.

every sticker you add gains you a 15% increase in performance.

every sticker must be different.

Supercharger

Hi guys

Hahahaa what a cool subject to be debating lol.

Hey

Has anyone ever tried water vapour injection to see if they can get better performance/economy from a 2 stroke? I have read that (only 4 stroke car engines) that water injection can make the air denser hence more oxygen and thus improves rev range, fuel economy and also a slight power increase.

I would love to try it as these engines provide plenty of heat to get a copper line to boil water as it passes through it providing it is coiled around a header pipe or summat like that.

Ya never know, if it aint been tried yet it may just work

I think they used water injection on WWII Fighters.

Its better to break ground and head into the wind than to break wind and head into the ground.

Water injection wouldn't do anything for our little engines. What a water injection system does is prevent pre-ignition (detonation, pinging, whatever you want to call it) First off, it wouldn't do ANYTHING for ANY normaly aspirated engine, as all it does is lower the incoming air temp, so to see any benefit you need to have an outrageous amount of boost from a super or turbo charger which raises the temp of the incoming air above an acceptable limit. Something thats just not possible on the scale we use....
