happy time with a super charger(a theoretical debate )???

Boost bottles are still a debate. I built a lot of racing engines and we never used them, one of the guys I knew tried one and claimed he was never able to tell if it did anything. If you read the technical papers on them, you will find that they use the shock wave from the reeds closing, on a reed engine, not a piston port engine like ours, and a twin cylinder at that. I saw a few on Moto bikes but our bikes beat them so why would we do that. There are some here that claim that it helps, I think I would try just to prove a point, but I don't want to mess up my intake runner. Have fun, Dave

The main problem that I can think of (off the top of my head this early in the morning) with either the leaf blower and PARTICULARLY with any type of nitrous setup would be getting your AFR correct (air-fuel ratio). With the leaf blower setup, you'd either run correct at full throttle and rich down low, or correct low and lean up high. It would be very difficult to get this just right. The nitrous setup would be the same times 100. With nitrous you are basically injecting more oxygen into the cylinder(s), which leans out the AFR tremendously and if it goes lean with nitrous you get a nice popping sound (esp I would think with the low quality chinese engines) and scatter parts and probably oil everywhere. Even if you could get the AFR correct, I question just how much additional stress the parts in one of those Chinese motors would take.

Good luck and let us know if you try either setup,

With nitros part of the system is a direct injection of fuel with the gas. You are correct in assuming that the parts would scatter all over the place. If you could see the size of the bearings this engine uses you would not attempt it. The main bearings are 6201Z, there are some with 6202, they are larger but not that much larger. Have fun, Dave

Sometimes. There are three basic type of nitrous kits and with all but the dry system you need a seperate fuel pump (usually high pressure to properly atomize the fuel with the oxygen (nitrous). The three type are:

The Dry System, which is the NOS system in which no fuel is sent to the intake charge outside the vehicle's normal means.

The Wet System, which is the NOS system in which fuel and nitrous oxide are supplied through a fogger and then sprayed through the throttle body (or intake manifold).

The Direct Port System, which is a Wet System in which each engine cylinder has its own fogger. (which obviously wouldn't apply for a single cylinder engine with a carburetor)



I think putting a nitrous kit on ANY of these little engines is just asking for trouble, but I'm SURE the Chinese stuff would be even more vulnerable. There are so many variables that are difficult to control with nitrous (tank pressure is one big one). It's not even worth exploring on these little engines. I would think that carb, compression, and exhuast mods would get you way further with less comlexity and more reliability. How fast do you want your bicycle to go?
