<<   Lynn,
      At the rpm we are using in our aircraft (Typically 5500 to 7500 <with 2.85 to1>) what is your gut feeling on using the Weber jets "and/or" the race rotor bearing if you were going to fly behind it.....?
    As for my "Delta" I have two 26 gal saddle fuel tanks behind main spar in the
outboard part of the center section. They are aluminum, not fuel cells.

There is no advantage that I can see. If the temps are under control, the engine is under no stress below 8500 RPM. Anything over 75 pounds of hot oil pressure is adequate. Plus you can have a 800 RPM idle and oil pressure at the same time.

The ITA class runs the bone stock RX-7s from all model years. They shift them as high as 8,000 RPM all summer long without a problem. I would leave it stock..........

Who would believe that?

I would leave most of it stock. I would have a big street port and Tracy's apex seals, a new pump and chain and a modified oil pickup.
I would add one of Richard Sohns pump adapters and run regular Redline racing 2 cycle oil from a bottle on the fire wall, and 40 WT Redline in the sump. Everything else stock.  Well, OK, maybe a crank triggered ignition firing both plugs in a housing at the same time, at 24 degrees BTDC using a double output coil like an Oldsmobile. So no distributor or anything else in that hole.................................... OK, I would use the distributor hole for a breather, but everything else stock.  How about a 10% bigger Dyke with fixed gear and full coverage gear doors on the wheel pants and a full swiveling nose wheel.  Two gull wing doors. 4 real seats. A 300 HP three rotor and a 2 speed 6 pinion PSRU and two 22 gallon fuel cells? Lynn E. Hanover
