Bought a five gallon jug of leaded 110 octane "VP" brand racing fuel. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)
My motor seems to have higher than stock compression. Lowest is 160 PSI. My speed shop guy says the valves will like the lead. (IMG:http://www.914world.com/bbs2/html/emoticons/chowtime.gif) Maybe I just like throwing money out my open windows at speed... (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) KT |

I've never heard my 6er ping, but have felt it...back when I was workin' on the tune.
According to B. Anderson, pinging in a 911 motor can be nearly inaudible....which would lead one to assume that if you can hear it clearly, it's not light. I'd back off the timing till you get it worked out or you'll be a sick freak with holed pistons. |
