Awhile back wasnt there a fellow Bueller on here with a home made? Supercharger unit on a Buell lightning?( might have been a modified pro-charger? It was fairly large ) I remember guys where drooling over it, and would have sold there Mother to buy the bike. Anyhow I came across this MINI Supercharger that due to its Small size, would fit fairly easily with a little modification. Also having relitivly little boost pressure boost regulating would be slim to none . 1324 You said you whee going to lok into turbocharging your lightning in the future. s a rule of thumb In motorcycles the Superchager is the tool of chiose over the turbo charger due to constant, linear turbine motion from Idle to redline with a supercharger VS the drag/lag then HIT of the turbocharger . the Supercharger uses more HP to run than a turbocharger. But the smoother delivery out weights the loss in everyday use . take care jake http://www.hscsupercharger.com  (Message edited by jake318 on November 23, 2010) | ||

For a Size refferance . The engine shown is ONLY A 5 HP BRIGGS & STRATTON mini bike engine . What do you think for dimentions ? 6 X 4 X 6 | ||
| Iman501 |
its cool, but how much is it? | ||

[Quote]We do not currently offer any automotive-sized superchargers. The "V-12" supercharger kit for the 5 hp Briggs and Stratton engine used in kart-racing is our exclusive product at this time.[/quote] WAS a great find until further down the page. | ||
| Jake318 |
RAT the last line was what DID make it a great find lol. With forced air , its safer to be under sized than over sized. And if comparing application look at the displacement not the HP. RATFINK beleive it or not that BRIGGS is almost 500cc !! briggs needs to use TONS of displacement to have ANY reliability/longevity being the metall is SO crappy is more like sawdust & glue than metal lol. With this Supercharger being SO little , you might be able to hook it right up without blowoff valves ect and be done with it ... I woulndt bet the ranch on it though lol. | ||

Probably need one for each cylinder on an XB, probably better off testing on a Blast since they have lots of extra room. There is a belt driven blower for other Harley v-Twin engines that should work on the XB if you can make it fit in the frame. | ||
| Terrys1980 |
That Briggs is no where near 500cc. A 5hp motor is around 150cc. | ||
| Wolfridgerider |
and for 900 bucks you can go from 5 hp to 7.5 I think I would just buy a different motor. | ||
| Ourdee |
I had a Briggs 5 horse red engine that dynoed 7.2 hp @ 10,000 rpm on one of my karts, just on the motor. Attention to detail can get you a lot. Little stuff like indexing the slot for the screw that holds the butterfly in the carb so it is in line with the air flow. The direction of the spark plug's gap in the engine. drilling little holes in the piston to get the top ring to seal better. Tilting the engine forward to get the splasher under the crank to work the oil differently, etc. It doesn't sound very impressive at 900 bones. | ||
| Xoptimizedrsx |
Ourdee They gave me a DQ for holes in my pistons....lol For splash I added a different shape to my part. (bent it) dont know how that happened. we was running 8.2 Hp on the 5 briggs. but it got a DQ for shaved pistons with extra holes. well that and the case was decked since they always measured the heads I tried to pull that off. Guess if you win It cant be by a lap. he he he. My pocket bike is high HP... no turbo. High Comp and running on E85. POS CAG bike. lol with flat slide carb, triple stage reeds, two stage ports, high rpm TQ crank, big bore kit, revo exhaust. +5 deg timing key and ect ect. all I used was the engine case. Its gauged at 15.6:1 compression so its a bull to start. with all this done its still a POS Bike... Mike | ||

Guys, I am not saying that this little supercharger is going to produce substancial ower like a REAL supercharger set up . I was thinking along the lines of an increase of say 5hp? And as far as the 900$ goes ? That number goes down to 200$-300$ after the kid loses interest and dad is now trying to sell parts in a garage sale . Dont read too much into this , it would just be a neat experiment . Jake | ||
| Greg_e |
I think it is actually going to restrict the flow. You still have to be able to pump the CFM into the motor to make power, and what is the flow rate of a 10 horsepower motor? This pump probably has about a 15mm diameter inlet, vs. the 30+ on our bikes, that's a lot of area. And then you still need an ECM that understands manifold pressure to mix the fuel. I think you would be better of with a good ram air induction system. (Message edited by greg_e on November 25, 2010) | ||
| Jake318 |
greg you will get much more pressure than you think .95% of TurbosSuperchargers can pressurie 5X more pressure than needed .Thats why pressure regulators/auto shut off valves are so critical. They are OVERSIZED so to speak to spool quickly. i wasnt going to do this project , but if i come across one of these at a friends tractor races (racers/families have garage sales of parts from time to time ) ill buy it and bolt it o someones ..rat bike 400/500cc no blow off or regulating valves | ||

DQ = Don't Qount  The lap thing will make em open it up. | ||
| Greg_e |
I'm guessing at the size of that thing, and I don't think it will have enough volume to make pressure. It appears to be a Roots type blower which is a positive displacement device. Only a certain amount of air gets moved with each lobe during rotation. Spinning them faster to compensate for lack of volume takes away efficiency because the space doesn't have time to fill the void when it comes around. Maybe I'm wrong but it just looks too small to move the amount of air needed on a 90+ horsepower engine (at the crank). | ||
| Srwitt |
To expand on what the others have said, that supercharger is probably too small. If it did produce usable boost for our engines it would probably be well off peak efficiency for the supercharger leading to unnecessarily high inlet air temperatures. A lot more to designing a PROPER forced induction system than the that looks about right method. | ||

maybe this will get you there for a lot less money | ||
| Glitch |
maybe this will get you there for a lot less money I have a Kawasaki backpack blower. I wonder...  | ||

Rotrex supercharger on a XB engine here: http://www.hillbilly-motors.com/html/xbk.html | ||
| M1combat |
I think Rotrex is the way to go. | ||
| Jbolt |
This is a roots style blower from a 1.6L mini cooper s.  There has to be a better way to place pulleys to make more knee room. Any ideas? | ||
| Delta_one |
but who do you trick into hanging onto your hood with a leaf blower and a bottle of nawz? LOL dang that was an awesome video 
I would run a shaft instead | ||

If you really want to waste money on pontless (and worthless) 'go faster' gadgets then this as to be the ultimate..... http://cgi.ebay.co.uk/HARLEY-DAVIDSON-ELEC-SUPERCH ARGER-AIR-INDUCTION-KIT-/150513262629?pt=UK_Motorc ycle_Parts&hash=item230b4a2025 Claims of 20% power increases should of course be taken with a large dose of salt, but then somebody will doubtless fall for it. | ||

Here's one that claims 30 day return policy, anyone live near them? They claim up to 5 psi, I'd like to see that from that type of fan, I doubt it would do that even against a closed pipe. http://www.dragtimes.com/parts/HONDA-VORTEX-ELECTR IC-SUPERCHARGER-AIR-INDUCTION-KIT_250732486291.htm l VSS, LLC (DragTimes.com) P.O.

I would put the charger where the front left air scoop is at, then run the tube up through the frame. But I have the old style frame and maybe they didn't. | ||

Sorry, but "95% of turbos/supers can do 5X pressure needed" = False, unless you really don't need much over atmosphere. Superchargers are limited to fairly low boost (a few psi), and most need a bypass to keep from being too large a restriction at higher speeds. I agree with previous comments that the puny one shown above would choke an XB motor. Turbos with wastegates are technically UNDERSIZED for their applications, not oversized, to improve low end response, at the expense of having to bypass excess exhaust pressure at higher speeds. If your car turbo is doing 14psi max boost, it is certainly not capable of 14x5=70psi. State of the art heavy duty diesel turbos for OEM's run in the 40's psi, and they are far more advanced than normal passenger car turbos. They are typically sized near their max capacity. The wastegate in many cases is more to keep the turbo from overspeeding (they are already running well over 100,000 rpm in most applications) than to limit boost. $ per HP would be a pretty lousy deal if you only added 5 HP, compared to an exhaust, intake, or calibration change. That's why most folks that go super or turbo charged go for big HP, since it usually takes big $ no matter what size you power increase target is. Sorry if I went off the deep end. I have run an engineering group for turbo design for the past 4 years. | ||
| Delta_one |
that's sad if your turbo will only run 14psi, the turbo on my old Audi was a serious air pump. my waste gate developed a hole in the diaphragm and my ECM would kill the fuel pump at 1.5 bar of boost. the turbo was still spooling at that point too. | ||
| Blake |
+14 psig is more than most engines will tolerate and live for long. That about doubles the density from ambient. Most aftermarket bolt-on turbos will be at or below that amount of max boost setting. Hardly "sad." | ||
| Skidonenko |
"boost" is just a measure of the intake restriction (not meaningless due to the heat). It is all about the air volume they can create and the engine pump through it. Waste gates and blow off/bypass valves are to get rid of the excess pressure, during closed throttle and deceleration or to keep the max intake pressure at wot at a given amount. Example you have a supercharged engine running 14psi of peak "boost" at WOT and the bypass is set at 15psi. If you take said engine and install a more suitable cam, larger valves, better heads etc. the "boost" number will go down but power will go up because you removed some of the restrictions in the engine. | ||

Sounds like someone has been doing their homework... |
