Hello around here.
Hey Joe, are you having any pinging issues while using 87 octane pump gas?

 

Hello - I have been running 89 octane with no problems. I havent run 87, but the engine builder dynoed the engine using 87 octane and indicated that there was no sign of detonation during the dyno pulls after viewing the plugs.

 

Nice for a boat anchor !
