Supermono 1300cc racer project.

[Propellor]

You were spot on Propellor, I just got word from Tony Foale. 30 hp

Well done.

Your postman just happens to be called Tony foale, right?  You're not talking about THE Tony foale, right?

Gulp.

Hee hee, only joking. No problem. I didn't really do much!

Next question is why?

[guest1306]

Yes Propellor , the Tony Foale. He says 29.3 hp.
Anyway now i gotta study those mathematics a bit harder, so i can work out for myself in future.

here are are a couple of videos of the recent dyno runs

[guest1306]

this is the clutch , and how it will sit on the engine. the outer teeth are gonna get pulled out.

[Propellor]

Making progress. Looking good.

Difficult to see on the photo, but are all the teeth on there involute gear teeth? I recall you mentioned somewhere in the thread that you're thinking of using a duplex (or even triplex?) roller chain? Is that still in your current thinking?

How will you go on with torque pulses? Will you build some sort of damper into the rear wheel?

Cheers, Andrew.

Propellor - i have to drop the clutch in rear wheel idea for now, otherwise i wont have a chance to get her running next year. This will have to do, with a sprocket behing the clutch, and a big ally spider to activate (and protect in case of wipeout) the clutch.

torque pulses- they will just have to be there , and do their worst. Hehe

Hi john.

How's progress going? Making headway?

[guest1306]

those outside teeth on the 1300 clutch are gone, otherwise not much progress apart from the brakebench is fixed up again, and ready to test the 500 Hybrid which now has Wizards of Nos laughing gas system installed (i am awaiting a fuel jet for the Pulsoid)

Looking forward to the results on the brake.

Regarding the last run (and this is probably not the case, but just a, thought) is it possible that there was something not working properly with the water turbine, preventing the turbine from fully loading the bike engine?

What I mean by that is that the engine will only load as high as the driven device will allow. If the driven device peaks artificially at 30 hp (due to an unknown problem)then that will set the limit for what will be shown on the load cell. Could be cavitation or excessive pressure loss? Just a thought and probably not the case.

Good luck. Keep us informed.

Well Propellor, the bearings were pretty much seized up in the turbine axle. I guess that if they had been new ones then the turbine would have maybe spun a bit faster than what it did. In 3 weeks  time we will see a pretty interesting video and results.

That might account for some torque which is absorbed but which doesn't show up on the load cell? With any luck!

I'll have to mull over that one a bit harder.

slight progress before Xmas - the final cut in the bronze head sealing ring bushings, an exhaust bandage and exhaust cooling flange

I've just read all seven pages on this project, and I think my brain has just melted! Actually, to call it a project is a total understatement. I'm totally amazed and can only wish you the very best Ellwood. Also, thanks to Propellor, for some of the explanation, though I'm afraid as a non-engineer, I only understood a fraction of it.

Ive been very out of fettle recently with a double lung embolism, but have managed a tiny bit on the head, and designed a few more bits on the autocad.





looking forward to picking up soon, and a possible new record speed in 30 days time on the Flying Kilometer on Ice race with my old 500cc Hybrid - never got around to proper bench testing with the laughing gas.

[Propellor]

Sorry to hear about the lung jobbie. Hope you get well soon. Good luck with the ice run.

[guest1306]

so now this is how the clutch will sit, for now anyway. there will be a spider around it, which activates the clutch, and protect during wipe-outs. now i can design the flywheel/clutch axle with necessary splines.
