ok, well, maybe ill go a different direction haha...im new to compression stuff, according to wikipedia (i know, i know...) then higher compression can make your engine more susceptible to knocking and reduce efficiency, but earlier it said it can get more energy from a given amount of a/f mixture. so it should increase power and efficiency unless it knocks, so do i need to run a higher octane fuel or additives? sorry i dont know much about this, anyone know of a good link to help me understand, didnt see what i was looking for by searching on here, maybe ill go the dist recurve route (wvenable, know how to do that?) and maybe put my bigger focus on stopping it haha! it still has 9in drums all the way around, going to go browse the brake forum now
