i have been running E85 now for three years now with no problems. i have a 3 circuit 1050 set up with the qwk fuel kit. i have went to 99 MJ and bumped up the timing 2 deg over my starting point in 2009. others i have converted also run with no problems. at MMW i ran a best of 9.89 with the trottle loose to run the 10.0 and john cope (CRT) ran a best of 9.94 and jerry hayes (MOPARPITTBULL) ran solid 9.80's with a smaller carb to slow it to the 10.0s. E85 ROCKS.....
