what up. Ive been searching the net and asking people but nobody has been able to answer my question. I wouldnt mind building a crazy NA motor but the problem i face is compression vs octane. I no if someone wants to build a NA motor u need high compression, but the problem is that the higher compression u go, the higher octane u need to go. My problem is that in my area the highest octane u can buy at a pump is 94...i can buy octane boosters, but i dont want to buy a booster everytime i go to the pump. Does anyone no whats the highest compression u can have inside your engine using 94 octane before the gas spontaneously explodes because of compression instead of spark. Thanx
