The flow numbers we are seeing on the production cylinder heads are very similar to the other flow numbers posted. We are very pleased with our initial test of the intake port on the prototype cylinder head we are developing. They are: Lift cfm .100 101 .200 162 .300 234 .400 344 .500 349 .600 380 We will have both a standard production cylinder head and our version with us at Cecil.
wow !! is that a 110 cfm jump from .300-.400 ? if thats accurate then that is awesome, looks like a 72 cfm increase between .200 -.300
The testing is ongoing on a Super Flow bench at 28. We did visit the Bulldog both at the PRI show last year. We are currently working on the intake port. We have yet to develop our own exhaust port for this cylinder head. The intake numbers that we posted are on the conservative side. These numbers are without any back cut on the valve, and dont include our race style valve job. We know these additions are worth between 8 and 20 cfm depending on the port design.
