Well now I'm just trying to wifure out which of the 2 I should get. They have the regular one which looks like this...

I still run a 2g MAS so I'd be getting the one on the bottom for recirculation. Mike at Forge Motorsports told me that this will hold without a problem at 30psi.
Also he told me that I can get the RS model with a 1g flange attached. The RS model he said is larger, so it can bypass more air. It looks like this...

Basically from what I've gathered, it'd be comparible to like a TIAL, able to bypass a larger amount of air.
Of course I'd like to have the larger one, but it will cost $85 more then the first one. I am running a 50trim, so I'm thinking the first one will probably work fine for my setup. Anybody have any thoughts on that? Does a 50trim at 25psi really push out that much to justify getting the larger one?
