Port flow relationships
« on: October 05, 2009, 11:10:34 pm »
Is anyone one willing to give up the percentage of port flow differential? I have collected a flow bench, and want to start tinkering with a 28 OHV. Thanks, Kevin

the exhaust 80% of the intake would be a good start

a great read is the website, mototune.com it's not only about flow through a head, its about keeping what flows in, in before the valve closes.  Search D port heads should give you some good informations as well.
