Banks Brake / Exhaust Brake question
 

I currently have a banks brake. To make a long story short I will be adding a compressor and air tank to my truck to operate some hadleys I have.
Something I've always hated about the banks brake is the "Big Head" actuator. Mine sticks a little, although still functional, and I intend to change it over to + pressure air operated setup.

My question is this:
How much force do you think that bighead puts on the pivot arm of the butterfly?
In other words, how much force is drawn by the actuator or required to effectively operate the exhaust brake?

Thanks in advance

I'm thinking no more than 25 psi since the exhaust back pressure cannot see more than 30 (stock exhaust valves)

Any opinions at least?

bump for a response

How 'bout me rephrasing the question.

Does anyone out there have a air pressure actuated turbomount exhaust brake. What ever the brand. Do you know the size of the air ram/cylinder that is mounted on the brake? Dimensions please?
