The SE 255 cams INTAKE close at 25*.. Good cam for MY purposes, 09FLHR.. I like the added lift and the early close of the intake,puts the power-band (lower RPM power) where I can enjoy it on the heavy bike..
Now on my FXDS, I liked the power band in the Mid and Upper RPM range so I went with a intake close that had a bigger number..
Intake open and close is NOT All that is needed to look at but it is a start..
When looking for a cam that HAS Low End Torque at Low RPM, The intake closing is where to look..
IF intake closes above 36/44/50* these are considered Higher RPM to get torque the RPM band is up, meaning you have to REV the engine to get INTO the power area...
There is a 4*(+ or -) wheel gear that changes the complete Timing Of open and closing the vales... this takes a little Study to apply BUT get results...
I think Steve07 uses this gear to make his power come on earlier on a later intake closing cam..
Making the later close on the intake close EARLY for more low end torque (lower RPM)..
