Thanks you Gentlemen,

I will get the CAD drawing done from one these CAD freelancers on
the net and post back the results. . Just one question - which of
the three SAE 1,2,3 will go with the FORD transmission parts from
slausons ?

I saw this photo o various Ford planetary gears on the website, how
does each one effect the reduction ratios

The planet carriere with the square theet is 3.12 and the other is
2.85. Hold the ring gear in both cases. The flange # goes with any
gear box. The big flanges are for wood props.

Paul Lamar hold off on the email. I'll be back in a few days.




You said the planet carrier with teeth is 3.12 and the other is
2.85. I was looking at this gear box
http://www.aeromomentum.com/gearbox.html he described the ratio of
his gearbox 2:5:1  Designed for 4 cylinder engine up to 210LB horse
power. In terms of horse power if that is the correct way to view
the ratios what horsepower should be used with 2.85 and 3.12

Any HP number.

Here is a little quiz. If I have an engine that generates 200 HP at
6000 RPM what is the torque?

Paul Lamar

(Torque * rpm)/5252 = HP I think this is the equation, off the top of
my head (too tired to check it...) .  Solve for torque.

Chris Cosman

Looks right to me.
