Hawk 250 supercharger
Hey guys I was wondering if anyone has put a supercharger on a hawk 250? I ask that because why not? I know I could rig something up just don't know how well it would work. Also felt like it was worth asking about before I try and do it and see what others have tried....

I have read comments from some of the vets on this site that it's a bit risky for these little motors because parts aren't "proformance " rated.

I was reading about people using smog pumps as superchargers on small engines. I don't think I will ever try but it's nice to think about.

Interesting, I was thinking of putting a battery of sterling engines on the exhaust, just a thought though and I guess more of a turbo then a super.... (point stands) while you may not get more than 4-5 psi hey its something.... Good to know about the smog pump I will most likely try that....

I think I seen electric blowers on the Web for about 75.00 not sure how they work

Seriously though... don't spend your cash on that crap... it's just a small fan that does nothing but cause air flow problems

I heard of one that does in fact work, catch being it only makes 4 psi and lasts about 10 seconds before the battery dies....

As for the actual project, I look forward to seeing what you do I'm all for 'More (reliable) POWER!' by any means

A smog pump won't work and neither will one of those electric blowers. To supercharge it you'll have to rig a way to get a pulley onto the crank or drive it off the chain but then it'll only work at high speed. A turbo would work but it's gonna be hard to find an adequate one without dropping a bunch of $. Either way you'll have to figure out plumbing, carb set-up, timing retard, possibly lower compression, possibly a fuel pump, etc. Unless you can design, build, and install the majority of the stuff yourself it'll probably be cheaper to just buy a more powerful engine.
A nitrous set-up would be cheaper and much easier. Being that it's so cold entering the engine it helps off-set the extra heat made by the extra power, especially when compared to the super heated air off a turbo or SC. I've searched a bit and haven't found anyone who's done nos or forced induction on a china bike so no clue how much the motor will handle before blowing. |

The smog pumps have been done by others you can see video of it on youtube. Would need to rig up a pulley for those. There are also some electric smog pumps not sure if those would work. I also doubt the stator puts out enough juice to keep it running.

The stator would probably keep up with an electric smog pump because they move very little air at low pressure, you'd get no boost at all. I did some rough math with a friend of mine for an electric SC for his Dodge pickup, I think it came to somewhere around 600 amps to just keep up and not make boost or be a restriction using 100% motor and pump efficiency which won't be achieved. If you strapped a leaf blower to your bike you might get some boost 'till you ran out of extension cord. At 12 volts it'll take well over 100 amps to run it and the stator makes less than 20 I'm guessing. |

NOS is the only thing I would even begin to humor.
