Blower Belt....

[Ron Hill]

I've been thinking....which if you know me could be dangerous....but aren't a lot of Harley-Davidson motorcycles driven with belt???
A blower belt with take how much horsepower?? What I've been thinking, why use a V-Drive? Why not a blower belt or even two blower belts...I don't smoke anything, but I do drink...
I've just been thinking... What do you all think??

Ron, it could be worked out, or in, however you want to say it. Interesting concept. No directional change, gearing at the switch of a pulley or two, much less friction of moving parts...........It would take a re engineering of the shaft log to allow for the side load needed to make the belt work, and the motor would need to be parallel to the shaft in order to keep the belt aligned. Interesting indeed.........What about the in/out part? How would you dis- engage it? Idler pully?? I've got a flywheel driven v drive Olds hydro we could play with.......Ray
PS: Bump up the octane, and give me another.........Yeah, the same as he is having.........

Gear ratios would be a little difficult....but you could drive the propshaft "out of the box" w/a constant velocity joint. (unsure of the power loss, but I can't imagine it really being that much).....and the engine would have to be "turned around" again. :boxed:
You could then mount the engine as low as possible (w/ drysump) to keep the CG as low as possible and then make the propshaft whatever degree you want it.

Cog belts are used on aircraft all the time to connect the engine and the prop. :cool:

Kevlar.

Kevlar.
Well that pretty much clears up all the details! :crossx: :mix:

I have seen this set up in a 4.2 litre (253cuin) hydroplane called "Beer N Boats" owned and driven by one of the true characters of hydroplane racing in Aussie, Greg Holland.
This class uses a stock 253 Holden V8 engine. The shafts are set up parallel and the set up is lighter than a v-drive, and ratios are easily changed as mentioned in an earlier post. The boat is extremely reliable and competitive, and runs well over 120mph.

Seems I remember hearing that turning the blower on a top fuel dragster takes over 1,000 HP. What is that belt made from?

Ok here is what I know. There is a guy that has built a 27 or 28 foot cat style tunnel boat with this type of set up. From what I know and seen he is running a single 600+ cid Blown Chevy around 1600 hp I was told. The set up goes through a W drive Casale because they are driving two Arneson Surface Drives. He is using kevlar belts to go from the W drive to a trans that drives the Arnesons. I don't remember how long the belts were but they are 5" wide 14mm kevlar belts. It is quite a set up. They are still experimenting so I have no idea what the reliablity is.

We plan on setting-up a deal with a 1400cc engine out of a rice rocket.. Turns 16,000 rpms, shaft driven w/ 5 speed trans..

That Jones tunnel I have, from what I understand was originally set up to run the prop shaft off a blower belt. After Dicks wife sold the boat somebody removed that set up & installed a transmisson & v-drive box.
