whats THE best plug GAP for 12psi boost ?
what plug gap would you recommend for a L98 with mid range cam and mast 11 deg heads and a maggy 2300 on 12psi I have come down from 35thow to 28thow is a lot better now in 3rd
1st 2nd 3rd are very strong but forth feels like the spark is still blowing out if I WOT under 4000 rpm if you ease it on it seams fine
plugs are NGK TR6 v power
thanks

thanks
