hightest we run is 94...in high compression motors, some b seris...so 95 is more than enough..

retarded timing can sometimes be a good thing when you mill the head. the higher compression gives you back the bottom end while the retarded timing gives you power up top

so is better go to near 15 avance timing ? (i have a chip that raise tha avance it self)from 15,5 now i put it to 16 and i see a drop in power after 8000 can it be real ? somebody told me that 0,5 in avance cant effect anything ....ohhh and 95 octane is not ron but purest than your 94 ......

so i do not have to put cam gears to abj the timing to cam gears ? ......or from compration only avance timing is effected ? and boys how can i find my compration ?
