Peripheral ports

[Grant Monkhouse]

has anyone got any other picture of peripheral port shapes?

just been searching for PP shapes and came across this, herringbone port 13B, put it in google and click on images, takes you to ausrotary and tells you the reason behind the weird shape of it!!!

no one has yet explained the reason for the shape of the inlet port??
 
only way i can see it is to reduce overlap but to gain maximum size inlet?

Maybe. But such reduction of area would do next to nothing in terms of overlap.
I think that they found through CFD simulation that additional area in that part of the port does nothing for flow and just hurts velocity...

Just to bump up this - What are the costs for having a housing peripheral ported in the uk?
 
~£500 each?

Like Carl says, it depends on whether you supply the housing or you have them supplied for you.

If you want to know the price of them then you could ring any of the rotary garages, Hayward, WGT, reworks, oldone, dragon, jaydee, I\'m sure I have missed one.
