Paul,
Using only two pipes will require fairly big injectors (or are you using
4) - anyhow you have taken an off-the-shelf manifold , cut off the top
because it is sloped for the car use and will attach 2 aluminium pipes

etc.

A Question if you don't mind:-
Have you  calculated the diameter of the 2 pipes to allow for the usual
things.

Do you have some knowledge on this subject that
indicates that this set-up will be satisfactory and can you explain your
rational - as I'm thinking of going the same way, but don't want to

restrict

intake !!

Hi, George....yes, I am only using two large injectors.  They are the same

as Dave Atkins in using. (I purchased the throttlebody, EFI, etc from him).
As far as the tubing goes, I tried to copy a wrap-over manifold that I
purchased, but could not use because of cowling clearance problems. I made
my manifold with slightly larger intake diameters, and approximately 5 1/2
inches longer than the "factory" intake manifold, so my best SWAG (Stupid
Wild-Assed Guess) is that since I am only extending the runners by about 5
inches, and increased the runner diameter approximately 1/2 inch, it has a
chance? Attached you should find a picture of the manifold I tried to
copy/improve upon. I hope this works OK, as it gives me plenty of clearance
above the engine in this configuration. I also tried to make it look
something like the Powersport and Racing Beat's aircraft engine's intake. I
should know in a couple of months.  I'll be happy to give a report ....good
or bad.   Paul Conner
