Auto. engine >> vertical shaft power output

Anybody know of a bolt on device to get a vertical shaft output from a 100+ HP auto. engine? No transmission.

Current options:

1. A RWD car with IRS. Turn IRS 90 degrees and block one IRS output shaft from turning.
Problem: Transmission weight and "crude" design.
2. Shaft drive motorcycle - turn the rear wheel axel shaft 90 degrees to give a vertical shaft power output.

There are many companies that make industrial gear boxes of various configurations. Chelsea is one that comes to mind but I don't know what they offer.

Are you rotating the engine? You will probably need a dry sump system and fuel injection.
 
No, by rotating I meant standing it on end. Sorry about that.
 

Rotating ( your definition :<) )would be an acceptable option but I have seen nothing on it anywhere.
I would be very interested in any information you can provide.
Thanks.
 
Output shaft up or down, what output Rpm ?

If it is down, how about a 100Hp engine from an outboard motor ?
 

Up or down shaft and rpm doesn't make any difference as I want to split the power into additional pullies/belts/chain drives downstream.

Re: Outboard motor

I recall someone experimenting with this idea several years ago but do not know if it was successful - probably not as I have heard nothing further....?

Someone once suggested that it would be easier to take the outboards power off the top flywheel . . . but I have heard nothing more about this either.

What I would like is to find a developed/commercial option.

PS. I think it is strange that will all the thousands of different types of machines available in the marketplace that there is nothing readily available that will give 30-150 hp in a vertical shaft.

 
The only real advantage of the outboard is that the oiling system, sump and carby are already designed to run with the crank vertical.

If a gearbox is needed anyway, might as well stay with a horizontal crank and turn the drive through 90 degrees.

How about a transaxle gearbox, with the bellhousing rotated ninety degrees ?
 
What is wrong with a normal differential with the differential gears locked, or replaced by a spool type centre, which converts the differential to a non differential bevel gear drive. That way you retain designed axle speed and do not load up the side gears.

Agree with amorrison. Lots of PTO driven mower decks have right angle gearboxes.
 
A stern drive unit from a power boat uses a 100+ auto engine and two 90 degree drives to transmit power to the prop.

Perhaps you could find a boat drive for sale that has had the lower unit damaged. You can bolt something in place of the customary gear box and skeg.
