I saw Predators run pretty good, but they are a PAIN on the street.
I am a Rochester fan. Had the good fortune to spend a week with Doug Roe in about 1980. I have his books, notes from the time we spent together. Best current book on Q Jets I know of is by Cliff Ruggles, but it only has some performance info on Q Jets and nothing else.
Roe was also a Corvair nut and a Turbo guru.
I put Q Jets on everything. I am not as good as Ruggles, will never rival Roe on anything, but I still try!!
Got a question - before I went to EFI I searched everywhere to find the drill bits to rework the idle feed restriction - never found a source for these @#$! extra long tiny bits. Roe referenced them in his book but never supplied a source. So where can you get them?
One night I got so frustrated with the QJet I started looking at EFI and never looked back.
I could get the WOT tune good but low and part throttle on a late Qjet no way without the damm drill bits.
