True but the sound of a blown motor is pretty nice I really wanted to hear to see if it sounded like a blower cause the nitro ones didn't sound like anything

I doubt it makes any noise.
 
The biggest downfall to the design is how it passes the fuel through the supercharger. In a roots style supercharger this theory works however in a centrifugal design you will have unequal fuel distribution to the engine at low rpm speeds. Wide open throttle is the only way this will even work in a sense.
 
I think a turbo charger would be a better option but even then I dought it. It looks good at first but the more you look at it the gimmikier it gets
 
The issue it there is no way to control the fuel delivery with the additional boost, it will blow the fuel charge through the cylinder as there are no valves, just ports that are exposed based on piston location in the cylinder. The point is to pack a denser fuel charge into the cylinder, this is hard to do on 2-stroke engines, you just waste fuel ultimately..

This goes for turbos and all trypes of belt driven chargers, it does not matter. They both do the same thing, just one runs off exhaust pressure and the other requires power, to make boost.

If you are to make any super charger or turbo work efficiently, you would need electronic fuel injection and EXACT fuel timing to be sure the exhaust ports are closed before fuel enters the cylinder, otherwise there will be a TON of unburnt fuel, not to mention ZERO improvement in power.

Im sure an engine head kit could be made just for Boosting. A special injector would need to be tapped into the cylinder, the most logical place is right next to the spark plug for direct injection. Just swap a bigger injector and add boost to make more power! This idea would work good with ANY charger capable of creating boost. Your carb would act as a throttle body and thats it.

soo- perhaps that noise was not music. it was the sound of horsepower!! lol.
 
I forgot to add possible HP numbers to my last post, if an actual supercharger system was made for these engines, I would almost bet a stock engine would see around 10hp .. With ported intake and exhaust runners and a fully worked lower end I would not doubt a 30cc engine would be able to produce 15-20HP. Also, I would imagine the intake throttle body would need to be the same size as the intake runner, not like they are currently where the carb is 12.7mm then jumps to 30mm or whaetever. I would really like to see one of these engines supercharged the right way and if they would hold together lol
 
That much power would kill these trucks. It would be fun for the minute that they hold together though
 
I was just about to say that mota lol. The drivetrain would have to be beefed up significantly. Actual drive shafts & not dog bones. Aluminum diff housings. Talk about a mangled mess lol. This is why I'm currently (notice I said currently) happy w/my oem detuned motor.
 
That power would not go to the ground, the vehicle would be all over. Sand drags would be sweet with some huge paddles! Titanium parts would be madatory at 20hp lol
 
Ok, so I found this. 1HP 4-cycle engine for weedeaters. If the block is around the same dimensions as the 2-stroke counterpart, we might have something here.. This motor would be easy to supercharge to make some power, not to mention, quieter and cleaner running! 4 -stroke engines put torgue down better due to the fact they have broad power bands.

Im just not sure if these motors have valves, or not. Still researching it.
