Paul,
I had researched the Holley system for my truck a couple of years ago
and found that it is not capable of suppling fuel above 3-4 psi of boost
pressure. I spoke to an engineer friend at Holley and he confirmed
this. The system is designed to run on low pressure and simply
referencing the MAP sensor to boost pressure would not have worked. I
forget all of the particulars now since it was a while ago but this is
the gist of it. You may want to contact Holley direct to confirm this.
But if it really cannot supply fuel above this boost pressure then it
will lean out your motor and cause a serious melt down. If you do find
a system which works for you and is a reasonable price I would be
interested in one for myself also. I still dabble a little with turbos
now once in a while.
Regards,
Ron

I have a friend who is using fuel injection on his Alpine. He has bought
a Holley Pro-Jection ECU (model 534-24) second hand but is missing the
manual. It's a long shot, but does anyone have a book for one, or have
any tips for the use of one on the 'Pine?
He is using a modified manifold with injectors in each runner, a Ford
throttle body, and once this is working a turbo will be added.
BTW - he has it running quite well at present with a GM J-car ECU.
Cheers,
Paul.
