Right... Helen of Troy rode on up the drive on her soon to be Bucket racer, a mint wee road legal FXR150.
Well 3 hours later it was a F4 bucket race ready for the track.
At about the same time a few of the BMRC lads arived for a club comette meeting, I was sent inside to get the beers and when I returned I walked into the garage to the sound of a howling wistle and a putta putta of a engine, cant trust them farkers as far as I could through em...

Welcom to the world that is bucket racing HOT

NB: due to the MNZ ruling that only a naturally asperated engine can exceed 100cc the blower has been removed as it was less work than re sleaving down

Of course, I recommend you head down to Bunnings first thing tomorrow!
Make sure you get the 1500w one though, anything less won't pump the right amount of air.

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.

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 !!

**F5 Dave** · 28th April 2009, 17:53

yeah it is, but in those dreadful 4 wheeled things F1 they had 1500 turbos racing against 3L normally aspirated & they managed ok I understand

(all my car knowledge is 2nd hand at best as I hate the stupid fings).

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

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.

Well DieselPig did it, but had issues with the oil presure so is lookin at a super charger.

mmmm, supercharged VFR800

Hey D, why not splash out and get some proper number boards for HOT's racer. The lapscorer will thank you! or her, or somebody maybe ....
