I was watching videos on youtube of a supercarged 454 ss pickup truck, and the guy had something on it that sounded just like a blow off valve, is there anything we can put on our superchargers that will do this?

 

Search for it.It has been asked atleast 100 times.
It won't work unless you invent some crazy intake manifold.I'm sure he had a centri where there is cold pipes from the compressor to the T/B.

 

zomg...dude use the search button

 

please post the video so we can see it.

 

it was prob. a procharger or a vortech...
