I haven't used any VRP products. I have a 72mm fixed SC pulley and upgraded from frozen boost hx and 1x CWA50 to DTK hx and 2x CWA50s and and massive improvements. Went from 22ish above ambient with terrible recovery to 14 above ambient with great recovery.

Looks like a good product but with the mods in your signature I don't see much of a benefit. I think it would benefit the guys stacking pulleys or running a 77mm SC or smaller.

I have one. It didn't make much (if any) difference in peak IATs, but it did significantly improve recovery time, especially at low vehicle speeds. It sits right in the path of the radiator fan so it does a lot more than the stock or oversize coolers do when your moving slowly or not at all.

The issue with this whole unit, is the little intercooler that sits under the supercharger, nestled in the Hot V of the engine.
No matter how much cold coolant flows thru it, your fighting against heat soak. Hopefully you have enough flow to counteract the heat soak.
