High compression and turbo

Couple of points, with that much compression your tuning window will be very small regardless of fuel used. The common understanding is either higher compression and low boost (10:1 and 10ish psi) or low compression and higher boost (8:1 and 20ish psi). You didn’t say if this was a street car or race car, or both, but IMO its to dicey to do a boosted street/strip car with that compression. Race car only is a different animal. If you decide to try I’ll make a few suggestions. I wouldn’t attempt this without standalone EFI, I use AEM infinity. Blow through and a standard distributor can work but precise control of fuel and spark will be the keys to making this work. I wouldnt do it without a custom grind cam, work with a cam grinder familiar with turbos. I wouldn’t do it without an intercooler, unless on methanol. Meth injection on top of gasoline is a crutch at best and shouldn’t be relied on in the tune up. FWIW everything I own is turbocharged, in that car 8-10 psi even at 9:1 compression and the correct cam, will be mind blowing the first time you stand on the loud pedal. Have fun.
