Bill,

          You do give me relief concerning the EGT’s.  I have no trouble in getting into the mid 1800 on takeoff at  6500 rpm.  Will try an advance in timing to see what happens regardless.  Other than that the motor absolutely Purrs, although idle below 1800 seems to not exist.  The resistors are for the injectors as they are the “peak and hold”.  The inlet manifold is the second attempt.  Originally I had a slide throttle which refused to slide under load, which would have been very awkward on a go around or having to “pull power” in a panic.  So I had to chuck it away and long story short, bought a throttle body assembly from EFI Hardware (google, in Melb Aust)  Only trouble was that the centres on the throttle body and the P ports were 10mm out of line or a little over 3/8 inch.  Had to make two adapter plates with a 7 degree 2 inch hole bored in them to get the two to fit.  Then the sexy double injector rails put the top rail right where the original inlet pipes went.  Was about to put a bulge in the top cowl, until I found that I had the room to bring the inlets in from the sides. Much adapting and polishing later, they are in place.  The PSRU plate and engine mount  is from Jeff Dodridge, and extremely well done.  Everything I look at has been done multiple times through ignorance, stupidity and necessity, but as usual there is no other way.  Neil.
