Here is a clamp-on bov adapter kit that I have made for the tC TRD Supercharger. Available for either HKS or GReddy type BOV's. Has 5 ply silicon piping, high grade aluminum adapter pipe, and stainless t-bolt clamps.
After adding this I noticed faster acceleration, and of course you will get the BOV sound just like a Turbo BOV.
Any Supercharger guys out there interested in a kit?

Is this a 50/50? If not, I thought you weren't supposed to use a fully atmospheric BOV.
Official supercharger info thread:NO FULLY ATMOSPHERIC BLOW OFF VALVES- Will cause a lean setting when you shift, the MAF needs the air to recirculate back through it so it can get a proper reading.
I'm guessing it's working for you though. Did you plug the return inlet on the manifold.

That just a bunch of talk... Actually if you think about it, that is completely opposite from whats happening. Air is already metered and fuel is calculated for the right amount of air, then air is dumped overboard leaving a rich air/fuel mixture in the engine.
Just like the 05-06 s/c cant fit on a 07+. Already proved that wrong.
Yes, I just used a plug on the supercharger outlet.
Guess someone needs to change that OFFICIAL s/c info page.

I might be interested in one ... are you having any issues with it chattering at idle?
I was one of the first people to get the Forge SPLTR and it would hold perfectly at wot but it made an awful chattering sound when the valve fluttered in non-boost situations.
