CVH flow testing
I am having a 1.9 HO cylinder head reworked and flowed.
I would like to know what flow bench results have been obtained by others. Standard valve size and oversize comparison.
Here the flow bench testers usually test at 28" H2O, and at .100", .200", 300", .400" and .500" valve lift. Intake and exhaust are tested.
Anyone have results they would divulge?
Cheers

Have a look around this website. It has a few flow charts for various cylinder heads that they have machined. I don't know how good the CVH heads that they have ported are, but I know there is a couple of tuners in this country who are very good at getting big outputs out of the 1600cc CVH engine.
I know that the US (and probably Canada?) market had different CVH head designs to European cars so you may find different end results.
