My 87 Turbo T seems to have a very well balanced combo, and is running terrific on 93 pump gas. I'm running 20psi boost with ZERO knock @ 18/20 timing. O2's are a stable 760mv @ 1620EGT during 3rd gear WOT blasts. With previous owner, the car reportedly ran 11.8x @ 114 on 23psi with an older non-progressive system that has since been removed. The car sees 200 miles a week as a daily commuter.
So... tell me what performance benefits I would get with a ~$450 shiny new alky injection kit.
I'm thinking the most I can "safely" push things with alky would be 24psi with 21/23 timing. (right?)
This would only net around 50 to 60hp?
I don't think I can run much more than 24psi without lifting the (never touched) heads. (right?)
Thoughts/Comments welcome.
