Cylinder Heads...

[NCTURBOS]

Fresh off the SuperFlow... These are for Twin Cam Harley's, with Ferrea valves. 1.94" intake, stock exhaust. They flow approx. 270cfm on the intake @ .600 lift, and approx. 225cfm exhaust @ .600 lift. A larger 1.625" exhaust valve is another option, as well as a CNC'd intake port that is hand finished with a larger valve that flows over 300cfm. :biggrin: However, that is for a race application only!!

Very nice. What are they going on? Good numbers for "smallish valves". I bet the low lift #'s are great. Everybody likes to kill Harley heads with the biggest valves they can stuff in them.

Honesty, they're not set to go on anything yet. Just another avenue for the cylinder head services we offer. I wish I had the flow sheet in front of me to quote the under the curve numbers. These heads would work great on a 95+ cui with some S&S .585's, etc... :wink:

We're anxious to do some more testing with the different sized valves, and real world testing on some bikes.
