smog pump supercharger!!!

[Kenny_McCormic]

I would come up with a manifold and inject after a butterfly robbed from some random carb.

you could do methonal injection too..... i still got to port my engine and shave the eyebrows along with building my minibike and mounting the supercharger

Meth+boost would probably blow the piston apart if the head holds on.

and it would not be good if the engine was between your legs.............

Stolen form 4cycle

Read that thread quite a while back, IIRC he said the pump didn't like gasoline and (IIRC!) it failed later.

Seals are cheap.

interesting.

Me and my friend are taking on a new project that has something to do with this. We are building an E-85 powered draw-through carb'ed smog pump supercharged (man thats a mouthful) Tecumseh 3hp flattie (I bet you can tell we have plenty of 'em around here, huh? ) It's actually a lot simpler than it sounds, but since you have to make the jets bigger for ethanol, and tune it rich to compensate for the condensation in the pump, It will drink ethanol like a mofo. Also, I was also thinking about using an air conditioner pump instead, because I heard you can build more boost than with a smog pump. (oh yeah, and the ethanol is an added bonus because it acts like a built in intercooler )

I'm hoping to achieve about 1 bar. of boost (that might be a bit optimistic though, and I'd be happy with 12 psi)

Good luck!

Thanks, I'm gonna need it

A AC pump with a hacked clutch(so its always on) might work better, they can take oil and might hold up to gas.

I'm going to attempt to build a semi-functioning turbocharger out of a vacuum cleaner engine. D'ya reckon you could use one of these to Supercharge as well? Might get a couple of psi boost.

 

[Kenny_McCormic]

your gonna run exhaust through a plastic vaccum cleaner? A turbo runs from an exhaust driven turbine, a super runs off the crank.

 

[BradenM]

The only part I would be using from the vacuum cleaner would be the motor itself. Would be independently driven by a battery, with custom plumbing, to empty the combustion chamber of exhaust gasses quicker, and to force induction. So I'd probably run 2. No lag from exhaust mounted motor.

i dont know how to power the smog pump lol, i have a belt and the pully is on the smog pump, how could i attach it?

 

[I like karts]

get another pulley and mount it to the crank. If it's a v-belt and not a serpentine type, it will be a ton easier to find a pulley.

Serpentine pulleys are easy to find.

 

[I like karts]

Not one that fits a 3/4" shaft or whatever. You can just find an old tiller and snag the pulley off the crank. Voila! 3/4" pulley
