10v cylinder head flow numbers

Postby dustin4kq » Mon Mar 05, 2018 10:51 am

Has anyone had a 10v turbo head flowed or have the numbers from someone who did? I have a head I played with but don’t want to pay to have a stock head flowed.

This is all I could find
He found that on an already "mildly" ported 1,800 cc, 8 valve VW head I
THINK (if I got any of the numbers right) that:

Valve Exhaust Exhaust
Lift in ? As Is / Was After P&P
FlowBefore FlowAfter
.01 of lift 71 cfm 88 cfm
.02 of lift 118 cfm 160 cfm
.03 of lift 134 cfm 184 cfm
.04 of lift 139 cfm 186 cfm
