Custom/Hybrid Blowing a 701?? Has it been done?

[Shadow7874]

By blowing i mean supercharging.
I recently read about a guy who has made some electric supercharges for cars that were able to achieve 4-5 lbs of boost.
Anyone ever tried making some sort of forced induction for a stand up?
I heard someone put a super charged sea doo motor in their ski, bit i mean something more of a bolt on.

I dont know much about super chargers but im studying to be an engineer so it would make an interesting project to try and ive already got a few idea, but its kinda a far out idea im thinking.

i don't see how it would be worth the effort. price/ cost per power gain.
just to make it because you want to or for engineering aspect, maybe
it's been done i'm sure.. hanging a (bottle) would seem a lot easier gaining the same effect.. just a lot less work. With the motor work and r/d that other people have in there engines (team scream for example) im sure they are more power the the average joe adding a forced induction type system without loosing the reliability.. just my 2 cents :crutches:

I see what your saying, and i could just have my head in the clouds but the idea i have seems simple and cost effective. Only one (big portion) im not sure how i could do.

But whats in my head, if it would work, is a bolt on blower that would be compact enough to allow room for the normal mods, but be able to achieve anough boost to make a little more HP

Ill do my homework, and get back later.

In the mid 90's Odyssey Racing used electric blowers (about a half dozen) to pressurise the intakes of their seadoo race boats. I have the mold for the carbon airbox they used. It worked well enough that IJSBA banned it from competition.

I have no real experience with this, just theory. Engineerd in training as well, almost done.

The two stroke concept makes it tough to use forced induction. Since the intake and exhaust port timing always overlaps. So you're basically going to waste some of the boost into the exhaust. Not saying it can't be done, just not sure if its really worth it.

Properly tuned expansion chambers can create up to 8 pounds of vacuum on their own.

I'd read some of the two stroke theory books. The two stroke tuners handbook by Gordon Jennings is a good one and there are other ones too.

If you look at the Detroit diesel engines, they are supercharged two-strokes with just an exhaust valve. Just a cool concept IMO.

quick question,
What recharges the battery in our skis? a Magneto or something like that? Im not sure what a magneto is but if thats what we use ill read into it. Anyone know how much power they can produce?

 

[Matt_E]

Yes, a magneto.
Stationary coil, rotating magnet, on the flywheel.
Enough power to charge the battery.

The lightning coil with the green wires attached supplies an AC voltage to the regulator which converts it to DC current and charges the battery.

The charging coil with the brown wire supplies an AC signal to the CDI to energize the ignition circuit.

The trigger coil is just a reference point for the CDI for crankshaft position.

Nice work... that's going to be expensive when that thing grenades. :biggrin:

I don't beleive that carb is going to work well with a blower, especially the way you have it mounted.

 

[Matt_E]

I believe Jared has stated before that the whole thing was a joke.

 

[z00m]

if you mean the 12v super charger that fits to the intake , they are s..t and have been proved to reduce power has they block off half the intake,

That was one of Glen Perry's great ideas.

Back in the day when there were only Kawasaki stand ups, Johnny-O (brother of racer Doug Silverstein) was selling belt driven blower kits, worked well.

stock system provides around 4-5 amps, if I remember correctly
