I'm using the rudimentary method for calculating quench. Volume of cylinder from top of piston to deck height (.025) + compressed gasket thickness (.026) = .051"
My SCR I used the calculator at CSG's site (
http://www.csgnetwork.com/compcalc.html) and DCR with the calculator at Wallace Racing's site (
http://www.wallaceracing.com/dynamic-cr.php). I'm calculating at 340' altitude for mine, just above the sandhills region of NC. I asked about intake valve closing after BDC to get a ballpark of how much DCR you'd be running. You have more than I thought you might. A lot of folks I've heard say above 7.8-8.0 you'll want to run gas with an octane rating higher than 87 vs. detonation. Being that almost all 87 octane fuels have 10% ethanol it actually pads that ever so slightly. How much would be pure speculation. But I'm accounting for the difference in stoich for ethanol blended fuels in my EBL/TunerPro stuff.
