Thanks for the insight 95imp and King.

So lets look into the Octane issue further:
In its NA, stock format, the LT1 combusts 93 pump gas, even lower octane 91 and I dare say, 87 without damage. Timing retard comes into effect, in order to mitigate detonation. What about heating of the rings/pistons? There should be a protection mechanism in place for this as well I guess? Your average person does not mix Meth or additional "E" into his fuel and the motor lives on happy.

Why would the same not hold true on a boosted application (I.E. TVS 1760 unit on an LT1 motor), as long as boost levels are kept at ?PSI and Timing Advance is kept at ? Deg. and Injectors PW is kept at ?mS for pure-straight 93 gas off your average Chevron/Exxon/Shell/Texaco pump?
Talking about a "good / responsible-safe" tune.

What is your take on this King? Can't it be done? Driving an LT1 motor with ZL1-like R-WHP levels, using LT4 fuel parts to support (Inj., HPFP, LPFP) reliably without blowing the engine.
There are even quite a few CA people with such setup (LT4 blower on LT1 engine), who daily drive at a lower 91 Octane without mixing "additional" substances in their fuel. For many good miles so far....
