Harnessing rear wheel power

[ecycle]

Greetings . Pitcher a motorcycle with its rear wheel sitting in a 2 roller dyno cradle. The object is to bevel gear the out put off one roller 90 degrees. Similarly I want to try to match the engine rpm on this shaft.( at least 3/4's) The rear wheel to the dyno roller is a speed increase . However the roller needs to be large enough to provide good contact to the tire. Figure 4 : 1 So all the reduction cant happen here . Which leaves the rest of the rpm increase to be made up in the bevel gears. And this is where things start getting fuzzy . The bevel gear out put shaft is pulling a axial flow jet pump which in most cases are direct coupled to the motor. Using the massive rear wheel torque to regain RPM to power the pump is what I'm after. Any ideas on how to track this down ?

Just a round about way to get there would be grate. Anyone ?

You don't really say what you want to do. Are you trying to use your motorcycle to power a pump? Building a test stand? I don't think you are getting any responses because your question is hard to follow.

I figured it out , 4 revs on the drum roller off of 1 rev from the wheel will work just fine. The rest is 1 to 1.
Thanks.
