I am building a Shredder (with some minor mods). Engine is 6.5HP @3600, to which will be attached a TAV2 with a 10 tooth sprocket. Rear tires will be 18" on a 1' live axle.

What tooth count should I be looking at in a drive sprocket?

All help greatly appreciated!

If it helps, the low ratio for the TAV2 torque convertor is 2.7:1, and the high ratio is 0.9:1; I just don't know what I should be looking at for a final ratio at the low end........

So I am thinking a 54 tooth sprocket (10 on the TAV2)

Comments?

Dude Im trying to picture your shredder,I had a ground hawg which sounds like the same thing. If you have any pictures it would b most helpful.My ground hawg with my 6.5 honda would almost lift the front wheels.It was fun!

This is the place that I ordered the plans from:

There are some pictures there.

I am making some modifications to the plan, such as using a steering rack rather than the chain system they use, and my tires are slightly smaller than what they spec'd. Also, the design calls for a torque convertor with jackshaft setup, but it is designed for up to 18 or 20 hp. I am using the TAV2, which is both simpler mechanically and cheaper.

Should look pretty much the same when done, though.

You are throwing me off with the tav2 what is it?

Sorry, it is the Comet Torq-A-Vertor, which is an all-in-one, and good up to 8hp so it is plenty for my 6.5hp

The TAV2 is a model of Comet torque converter:
