My only injector experience is with motorcycles, and there the hot setup is
injectors that are completely out of the plenum. They spray towards the
inlet bell. Seems like the further away, the better.

Subject: Tr6 PI and racing
I am setting up a TR250 for racing. Have decided to use PEtrol Injection.
So now the questions begin [I know Charly Mitchel here in Seattle area. He
is running PI this season in his TR6. He has had a lot of contact with Kas
and I hope to benefit from his learnins.
None-the-less, I thought I would quesry the august group about any PI
experiences, modifications, etc.
I located a whole PI system from a Mr. Priestly in NZ. $750 US inclucing
shipping.
Does anyone have have or know of any written resources [or URLs] regarding
modifying/imporving PI for competition purposes? Saw one where someone
suggested using one throttle butterfly before the plenum chamber and
eliminating the six butterflies in the throttle bodies
[seems reasonable -- no sync problem and simple throttle control.] Do
n ot know if this would be legal for 1969 racing specs.
I know Kas has suggests getting the injectors as far away as possible --
even outside the butterflies. Has anyone had any experience with this?
Other ideas/enlightenments other than replacing the Lucas fuel pump with a
more reliable one [Mallory?].
Thanks,
Chuck
