What is your trap rpm now? i trap now at 5000 in the 1/8 mile no 1/4 times yet./with the 306 mag it would go the 1/4 mile and trap at 7200/7400.What was it before the tire change? Is the M1 still on it? What compression is it? Any exhaust beyond the headers? i have 3'' pipes going ito flow master muff. and cut of right before the rear..
So i have a combo of somewhere around 12:1(?)///i think in the line of 11.1 i have drove this on pump 93 no problem but try to stay at a good mix maybe 5gal. 93 and 3 gal 111 in 8 gal. cell.
