At 11.5:1 compression on a stock rod what IVC will put DCR between 8.5/8.7?
Help much appreciated. I've been playing with a DCR calculator on Keith Blacks website and it uses .050 figures plus 15degrees duration and it doesn't add up right. The SCR calculator seems spot on.
62cc head chambers, 2cc piston reliefs, .040 gasket, 4.030 gasket bore, 4.005 cylinder bore, .006 out of the hole, 3.622 stroke, and 6.098 rods.
SCR came out to be 11.515 I believe which is perfect. I'm looking for an 8.5x-8.7x DCR.
I'm wanting to spec out my own camshaft not only to learn but to keep busy while moneys coming in until this things back together. Problem I have now is my computer is getting rapidly slower daily and I deleted Adobe and others
to help it along. Little did I know I wouldnt find a DCR calculator without downloading something
