Greddy type R recirc'd to compressor inlet! Anything really that is fairly large that you can attach a hose to so you can dump it back into your compressor inlet. I advocate not being a ricer, plus not loosing as much boost between gears is always a plus.

I know you can add an air filter to the Mondo Bypass valve. That quiets it down.

I never hear my Mondo. At all. I have it set up to dump directly back into the Vortech inlet adapter. I know it's opening and closing when it should, but it doesn't make a sound.

No you can't use your stock bypass for 16-18psi. You will need a Mondo or something in a similar size. Maybe get by with the next size down, but why risk it?

I thought the greddy valve where BOV and where not good for the bearings on a supercharger? I am also looking to upgrade my setup and I think the Mondo is to large for my app. and the procharger race bypass is just huge....

I want something that vents alot I missed 2 shifts both times I tossed the belt and heard a rumor the impeller does funny things when you goof? Something along lines of needs to vent alot for goof ups. I dont know how true that is?

I would use the ATI Race Valve and it has an option to recirculate.

You can weld a bung into the tubing to recirculate it.

The show is still going on today, very few vendors and very few people attending the show. Bob
