Howdy Guys,
3rd and final post of the night. I am hopefully getting a complete 84DA 250 crossflow and am looking to make as much power NA as almost possible (If I'm not happy with it I'll supercharge). This requires some serious porting. Does anyone have a flow bench data table (0.100, 0.200, etc) of the CFM flow rate for the intake and exhaust? research online has led me with a max of 213 CFM @ 0.500-0.600 lift and some other person stated 340 CFM @ an unlabeled lift. Id be in the 0.543" lift range using 1.8 roller rockers on a 14650 Crow cam (292 ADV). I have yet to find exhaust numbers for CFM.
I am trying to use these to help develop a theoretical HP that the motor will make. I know valve choice will make a difference too. I'll likely try to use the largest I can ,reasonably, like the 1.94" (I even saw using a Cleveland 2.02"). what would you all recommend here as well?
Thanks!
