into the intake tract before the inducer? any formulas math involved to determine size/placement of the post inducer ports or is it a shoot from the hip kinda deal?

I've got a few comp housings on the way here to toss in the CNC and cad some stuff up for machining, but if I have a good idea/starting point it'll help me get this moving much quicker. I've got about 5 weeks to tinker with this idea before I have to give this particular car back to the customer ready for racing

Hmm...I own a Garret GT40 (soon to go in my Audi S4) with anti-surge mumbo jumbo inlet but frankly, I don't quite understand how it works. The anti-surge pockets don't look like something you could machine into compressor housing as intake mouth is much bigger on one with anti-surge.

The anti-surge part pushes the surge line to the left felt where mass flow is low but pressure ratio is high.
