Paul,
            Just for interest sake, just how long is the intake runner
 supposed to be, and where do you measure it?  If I start from the inside
 rotor housing I get 5 inches to the slide throttle.  Then around my very
 tight radius I get another 7 inches(Hard to measure a curve with a rigid
 ruler), then I get another 10 inches over the top of the motor to the
 mouth of the runner.  Is this too long ??     Neil.

 If you have a 2.85:1 gear box should be about 18 inches.
 Peak power will be about 250 at 7500 RPM.
 If a 2.17:1 gear box should be around 22 inches.
 Peak power will be about 200 HP at 6000 RPM.

 HP = ( Torque X RPM ) / 5252

 You must divide the Le Mans engine's torque and HP curves by
 2 because these curves are for a 4 rotor. Also it had 3
 spark plugs per rotor and other minor tweaks such as ceramic
 apex seals.

How about a 3.17 Ross drive single rotor?  A little shorter?

Lewis.

Yes. About 14.9 inches giving close to 150 HP per rotor at 8400
take off RPM.
