Volumetric efficiency of RX motor??

[lakercr]

Anyone know an actual number for it? Freddie?

 

[DYNAREX]

it changes with any changes to intake or exh system-even atmospheric pressure changes it
a close guess on a complete stock engine at peak torque is about 90%
freddie filters definately improve it

Thanks - BTW I should have indicated Ve at 10,500rpm.
