I'm running 10PSI right now. I had it up as high as 14, but one pull sounded like incipient detonation, so I backed it down for now.
It's a very simple +T setup - I used the Bosch LH 2.1 ECU (#507) from a '84 760T which is plug 'n play compatible with my LH2.0 setup. Added Ford Browntop injectors. I kept the stock Chrysler ignition box. The compression increase was from a Cometic gasket (0.027" vs. stock 0.049"), which took my 10.3 up to ~10.7. A T3 .60 trim compressor and 0.63A/R turbine housing with the ATP Ultimate Wastegate add power up top and flow well. I already had the K-cam installed.
Since this is just for fun, I wanted to keep things cheap but effective. Tight squish increases detontation resistance and lets you run boost. Higher compression gives you better off-boost response, and can let you run a wilder cam more effectively. A wilder cam will tend to come in a higher RPM. Making power over 3K RPM helps the NA pistons and M46 live longer. I sized the turbo compressor to come on with the cam for a synergistc effect. I sized the turbine to flow effectively at higher RPM. I put a TurboXS RFL BOV on for entertainment purposes only.
Wow! Interesting setup! I forgot to ask about hg thickness thanks!
Does the stock chrysler icu pull timing under boost?
What kind of trim do you run on the turbine?
