Thanks guys, do like Millweld box also, was a bit concerned with the snorkel flexi duct but see now it can be solid pipe mod. With box, was looking for proven H/F design as running higher end boost (need >600CFM). Will ring thru to Mill and see what the go is and he may have some results I can look at.. Had Mill do may rear bar at Mansfeild 5-6 yrs ago as it was one of the first new GU body shape builds. Like his work, and he can draw on a lot of experience. Do also like ability to easily observe Fatz air box contents and provides 1180 CFM flow(as quoted).

I run a Fabwitz sys (box/induction piping) but looking for possible improvement low down torque 4&5th. Fabwitz has offered to take back air box and I make dollar contribution for supply SS 4" snorkel (fwd face/safari ram hd) and swap pipe from box to turbo. Understand they do pipe to turbo for Millweld box also..

What boost / approx pwr you both running with your TDs?
