I have a blow through on my Turbocharged 86GT. No enclosure, I have heard they can be problematic but I don't have any experience directly. I'm just using a CSU 750cfm blow through specific carb. It's capable of handling the fueling for double what I make. I'm essentially a stock longblock, F cam, Weiand X-celerator for an intake and a Chinese 69mm turbo. Home built kit but has run 117mph at 6psi and just over 123mph at 9psi.

Not much help setting up an enclosed setup. Mine is just the carb sitting on top like normal with a CSU bonnet on top. Simple and effective.

My driveabilty is excellent, idles beautifully and transitions into boost clean. Kevin builds a killer carb and is working just as well on mine as it was on a blown 349 making 900+HP. I think I only dropped the rear jets 2 sizes to get the A/F where I wanted it.
