If by direct coupling you mean bolting prop to the crankshaft. Thereall that way. With an engine that developes most of its horsepower inthe mid 2000's theres no reason for a speed reduction unit. The onlydraw back is you need a prop that turns the other way.Ted .T________________________________________________________________________________

Ted,Just a thought, find out what prop the corvairs are running, and comparethat to what the fords or 65 cont. are running. See if the direct coupledCorvairs are turning a twice horsepower prop.walt-----Original Message-----

That makes since. I wonder what the horsepower/torque is being put out atthis RPM on a direct drive unit?I started to build around a Corvair but just came upon a Model A engine andnow I'llprobably us it instead.GY-----Original Message-----

My point was that you are putting out less than 85hp. My friend whogears the corvairs, is trying to get more of the 110hp out.waltps I think that the one he has now, the engine turns about 3800rpm andhe wants to gear it to run about 4300/4500rpm, more into the hp curve.-----Original Message-----

The engine puts out 110hp @ 4400rpm; But, the max torque is produced @ 2800rpm,and is 160 lbs. The hp at this point is 85.3 if I got it right. Should be one sweet engine.________________________________________________________________________________
