Anyone having a problem with the boost blowing off the carb boots after closing the throttle? Would you not install a dump valve?

Haven't had a problem in two years running between 10-14 lbs.

When I run it up with a track stand, stab the throttle then release, the silicon carb boots blow off.

I've only run as high as 12 lbs but hair spray on the boots works fine for me.

If you do not have a blow-off valve or a bypass you will benefit from installing one. These valves keeps helping the compressor in the turbo from stalling. When you abruptly close the throttle the pressure in the charge tube is spiking and that pressure spike flows back to the compressor. With a BOV installed the pressure spike is vented to atmosphere, this also helps keep compressor spinning building boost faster when you get back into the throttle, it also helps keeping your intercooler/carb boots in place.
MC-Xpress makes carb inserts to be glued with epoxy to the carb intake, it makes the hose seat properly to the carb when the host clamp in installed.

I just notised you have a supercharger - And I'm talking turbo, what a bummer. What I said may not apply to your application.
