My AL 104s are gapped at .054 on my 500whp turbo setup lol
No spark blowout with that much boost? Interesting.... I gapped at .048 bc that what knowlegable people suggested. When I dyno tuned the dyno guy thought I might get blow out at .048 but I didn't. Does e85 blow out easier than 93? i had the gap at .054 with 93 gas and a 3.2 pulley but made it smaller with the 2.8 and e85 with 15lbs of boost.
