Ok so the fuel pressure to 43psi at idle im running 93oct with smc alky kit.... boost is at 20-23# i never get on the car from a stop i always roll into it at about 25mph roll. (anything under that i'll sweep the street left to right) im on street tires. not sticky..im planning to hit the track this weekend so want to be tip top...i noticed tonight at wot i got a o2 808 / 0.5 knock on scanmaster and my knock gauge went into the 2nd/3rd green light.... know im wondering if if the car is over revving.? anyways....so i let off** i was running a boosted prelude anyways, should i raise fuel pressure? or should i try a different alky mix? or turn the pump speed higher? current pump speed is at 6 and its a single line alky... im currently using HEET with -20 windshield washer fluid ive used ethyl alcohol from cvs before and also home depot denatured alcohol with a cap of klotz oil? ive always tried to feel the difference but i honestly cant so im still on the quest of the right mix? what do the guru's think should i raise up my fuel pressure a couple psi try a different mix??
