Paul,

I don't know how much my static RPM's will help,
becase I have an adjustable pitch prop.  I adjusted it
to get about 5000 static.  Actual, at 5 lbs of boost
on the turbo in a climb, I'm getting about 5300.
It's a 72" prop, and I believe that the pitch is about
75".  I have the high pitch blades, and the pitch
range is 45-105" on the pitch.  Mine is about in the
center of the range. I'm using a 3 blade Ivo prop, quick adjust.  I bought
it because, I didn't know what pitch to run with the
turbo, it was cheap, and I can make it in flight
adjustable if I want to.

Hi, Steve...unfortunately, I tried that. I installed
two switches, one for each fuel pump, and turned them off first. Still had
the fuel drip.  Since my intakes run downhill, and the TWM throttlebody is
also pointed downward at a 45 degree angle, apparantly the fuel coating
the insides of the long intake tubes slowly runs downhill toward the
throttlebody, and eventually leaks past the butterfly.  I'm considering
installing the short intake I have from Atkins Rotary. It puts the injectors back
on the hot side of the engine, but should eliminate all that downhill
plumbing I have.  Thanks for your input.
      What kind of static rpm's are you getting on
your takeoff roll ? Thanks again.  Paul Conner
