well... had I not seen it for my self I would not have believed it, had to do some work on a fxr today and what ya know it had a blower on it... forced induction.
I have some pics giz a bit for the batts to recharge and ill down load em, got a good vid to sounds awesom but I dont no how to load a vid.

Looks like a plenum chamber , it might be to keep the compressor out of the inneficient stall region, as the engine is a twin it doesnt require air for all 720 degrees of the cycle . the compressor likes to supply a constant flow of air so it is stored momentarily while it is waiting for the inlet valve to open. electronic equivelent would be a capacitor

I think it is a pressure box for the carb.
The carb is designed to have air 'sucked' though it.
If you try to blow air thu it without a box around it imagine what would happen, Fuel wouls piss out the vents every-which way.

hahaha... look see its not even a turbo as I thought, well it is but modified to run with the engine revs so what you say isent quite right as the turbo spins with the engine not with the gasses so therefor a plenum which is a fancy name for surge isent nessaserly nessary... Koba has the right idea.

While super charging gives a more even power it takes power to make power, wereas a turbo uses wast energy to produce power.

I'd be really interested to know if the bike had carbs fitted. If not, and I cant see any sign of them, I suspect the red thing may be some sort of throttle and fuel regulater with possibly some sort of blow-off function as well.

As for the supercharger, they have fitted a similar sort of mechanically driven turbo compressor to lots of cars, Holden V6s for a start.

Ha ha, no not enough static pressure in an electric fan like that - ie pushes a lot of air with no resistance but put you hand in front and block the nossle of the leaf blower there will be almost zero pressure pushing your hand away. Those fans don´t have enough "bite" on the air. TTS do a range of pulley driven centrifugal rotrex turbo blower kits for bikes. Not so expensive either.

So I guess you just turn up the boost. . . until it goes pop & everyone laughs;)

Would an XL100S engine blown actually be compettitive against a tuned FXR?
An XL std puts out about 9-10hp and an FXR about 16-17hp (crank).
I'm guessing a tuned FXR 19-20 (crank-wise) so that's a lot of work to get the 100S engine competitive !!

You only need to increase the manifold pressure to about 15psi gauge inter cooled. Twice the air in is twice the power out, twice the power from a 100S, would make a light nimble bike. This would be good. But I think the big problem will be the original air cooling of the motor.

A supercharged motor does not have to go pop. Plop a supercharger on an ordinary motor and it will rev to buggery, but they can be set up to be very broad range high torque motors where instead of reving them out you short shift and use the extraordinary low end torque to pull you out of the corners. Great for wide ratio boxes.

You can get a small roots type blowers from small Japanese engines (diesels?) that were used for lean burn or stratified charge or sum such thing that would be an ideal size. If any one has one??????

But heat and muffling a supercharged motor would be your problem.

I would love one, in fact don't get me excited or I might just make one.

28th April 2009, 20:23

One could use a more powerfull leaf blower thats driven by its own two stroke engine for the supercharger. Just fire it up before the race. I spent a bit of time in Bunnings looking at leaf blowers as I was toying with this idea for forced air cooling on my GP125.

Others have run their water pumps from a battery as there is no rule that says the supercharger or forced air cooling fan or any other accessory has to be driven by the prime mover and can't be run by its own internal combustion or electric motor, but I didn't really want the controversy and it looks like the copper is working out.

As the GP's carburettor is in its own plenum chamber a fun thing one day when we have the bike on the dyno would be to pressurise (supercharge) the chamber with a leaf blower and see what happens.

Or maybe I could get one of the other's to let me do it to their bike, now thats an idea. ;)

.

TZ350

28th April 2009, 20:56

Now here we go:-

Drive the compressor end of a turbo with one of those cheep 2-stroke mini bike motors to pressurise a plenum chamber with the carb in it and you have an arrangement like this. I reckon it could be done. I almost want to do it, dam superchargers are exciting.

I reckon a Turbocharged CB100 would be a formidable weapon. The little 100's go quite well if you keep them wound up. Avalon/Keith Biddles is a good example. In the right hands it's at the front of the 'A' grade pack

The Turbo from a 3 cyl Diahatsu Charade is one of the smallest around and quite a reliable unit (If you can find one). I saw one setup mounted to a manifold for fitting to a pit bike. No reason why it couldn't be set up for a CB100 tho

I was playing with the idea. But when I told granma Wobbler she had a Hissy, told me I crash too often as it is. :yes:

Nos is great but when you squirt Nos you have to squirt extra fuel too. Easy to do if the extra fuel is from a small LPG bottle.

But just in case anyone needed to know.

If the compressions not to high and you have the bike all nicely set up and tuned just right on petrol.

You can dribble lots of nitromethane in front of the carb and allow the motor to just suck it in when you open the throttle. More nitro = more power, lots more nitro = lots more power and I expect it will run perfectly.

Thats easy piesy chemical supercharging. Nitros about $25 a litre from your aero model shop.

Don't tell anyone you heard about it from me.

I like Yow Ling's idea of using Nos to supercharge the XL100. The rules don't say the super charger must be driven by the engine or even be mechanical in nature.

29th April 2009, 22:53

350, you're freakin' crazy........ I think you should try that copper head setup thingy in a model airoplane......... Nitro Methane till you're heart's content.......

Anyway, correct me if I'm wrong but my understanding of NoS is that it doesn't really add power, it just assists with cooling therefore allows you to get more power out of an engine without additional cooling etc. With that in mind, could it be legal on a bucket? It's not fuel, more like total loss cooling system..........

29th April 2009, 23:42

NOS is an oxygenator, when burnt it produces oxygen which allows more fuel to burn.
RE, the turbos and superchargers from 660cc cars, there are just not made small enough engine would be peakier then an old 2-stroke.
But there is a bucket way, oh yes!
Get an air con or smog pump from a car and use that to supercharge it 7psi no problems
Loads of info here http://www.elsberg-tuning.dk/the%20bikes.html
