What octane gas with riva pistons?
Looking for opinions on what octane gas people are running with the RIVA high comp pistons.
I have the RIVAs in my ski and it motor is not broken in yet. Cam timing is fully retarded and static compression looks to be 155 to 160. I will be running x charger to start with and will likely upgrade to a mini rude later. Les Cooke ECU spinning 8800 and the rest of stg 3 stuff installed.
For break in I was going to run 10 gallons 93 octane with 3 gallons of 110 to give me some safety margin. Is just running straight 93 safe?

there are a lot of missing variables. How much boost, how much final timing, and what intercooler?
I run high boost and an aggressive setup, and run 50/50 mix Sunoco Supreme / 93 pump (prefer Shell)

What if it were a Riva ECU @ 8500 ? Would it be more pump gas friendly ?
