ok, i will have to check the plugs a bit more, they were black after the pull as it was very rich set. But i my buddy who has thge dyno has a lot of experiance working with high horspwer car engine on noss adn was thinkin he could see a couple of small dots of aluminum on the plug we pulled. say it might be detonation, we only did a couple of 6 second pulls. I hope your right on the premium black. that would sure make life easyhate to have to run race fuel. boss noss say premium only to 30 hp and 100 octane after that.
i usually run premium with my 60 h.p. boondocker kit, some people say boondocker don't make true stated h.p. though (i myself have never dyno'd to see), reguardless with many bottles passed through her i've never had a peep out of the motor on premium.
