I did some form flying on Tuesday a.m. trying to keep up

with some other

RV's.  A buddy of mine was in his RV-8 with a 180+ h.p.

with a c/s prop.  He

was lead and would set 19" MAP at 2500 AGL and I had to run

about 27" MAP to

keep up with him.

Dave,
what was ground level hight above sea level, and what was your

engine RPM?

Ed, I meant 2500 MSL.  At those settings I would be showing about 130 KIAS
and about 5200 RPM.

BTW, I ordered up an HKS manifold to go with my TO4E turbo yesterday.  If it
all fits I'll be getting the biggest waste gate I can find along with an
electronic boost controller.

I also need a bigger prop.  I have noticed that EGT is more closely tied to
RPM than to MAP.  With a bigger prop I could use more MAP at a lower RPM
without going over my "limit" of 1650 on the EGT.
