Subject: MUSCLE PLANES - CORRECTION

 

A normally aspirated 3-rotor with 2.17 to 1 reduction gets you started at
about 265 hp (loafing), at a weight under that of an IO540.  If you want
more power go to 3.5 : 1 reduction and get about 320 hp for just a few lbs
more in the cooling system.  Add a turbo charger and some porting, and go to
600 hp, but only if you want to win at Reno.

 

In a post a few days ago I referred to 3.5:1 reduction.  That should read
2.85 : 1.  Fingers on 'fast forward' - brain on 'pause'.
