Sorry I have been out of communication, I have been busy settling

into

my summer job. Attached are some pics of the CF manifold I am
designing
to fit Jerry's PP. Nothing in the design is sent in stone so

everybody

feel free to send comments. The plenum is placed so as not to
interfere
with spark plug removal and currently has a volume of 1 liter. The
plenum intake can be towards the front or back of the engine.   The
length of the runners is 21.5 in. With the PP TB and runners the

total

intake length is 25.7 in.  On each runner 1 fuel injector will be
placed
near the TB and 1 near the plenum. Instead of fuel rails I would use
the
Electromotive Injector Cap Assembly which has AN-4 fittings on top.
That?s all I can think of for the moment.

The runners are too long Alex for 7500 RPM.

Alex,
Why did you elect to have one injector on Plenum side and one near the TB -
rather than two near the Plenum?
I thought conventional wisdom was to have the injectors at the far end of
the runners. I thought the reason was that excess heat in the fuel-rail was
returned to the fuel tanks.
