Doing some head flow testing for a customer. He sent me a set of CNC ported SE110 heads for a blower Application to test. Well, not that impressive for a CNC head for blower setup. His heads are 289.0 CFM@28″ and are done at .500″ lift. Ours are at 325 CFM@28″ and carry to .700″.
The green line is his heads and the blue line is a set of our heads. Both are tested with a 58mm TB. Ours was SE 58mm and his is S&S 58mm TB. His has way to big of a body for this Application. Looks like we will be fixing his setup.
