Hey on RevItUp Motorsports web site they have BOV's under the Cobalt SS is there something i missed i thought they would not work ?

 

They don't. The LSJ uses a boost by-pass valve, which is not the same as a blow off valve.

 

shouldnt there be a way to convert the boost by pass valve into a BOV?? to a DEGREE it does do the same function...i dont know how GM has it hooked up but may be vent it outside?? but that would probaly throw a ECL...althought bov's can be exremely annoying so mayb not lol

 

when you start to push high psi out of something other than the stock blower (s/c) you'll want an atmospheric bleeding bypass valve (over 12psi), other than that, you don't need one, or want one yet.

once people start with the twin-screw swaps, they'll be using the atmospheric type if they're pushing well above 12psi

blow off valves are for turbo cars that need to release the pressure built up between shifts when the throttle plate closes

 

so then if u plan on installing a PSI FI kit it might be beneficial since i hear itll bring boost up to abotu 15psi, but then again i havent seen to many people with concrete results on how much boost they are running...

 

bov's are for people doing turbo and tein charge kits, a bov will not work on our superchargers

 

were can u get these psi fi kits and were are they placed on the engine once u decide to get one?

 

Psi Fi kit consists of a smaller supercharger pulley (2.8"... stock is 3.3"), large idler/tensioner pulley (To pickup the extra slack from the smaller supercharger pulley), and a piggy back computer (which is soldered into the engine wiring harness).

You should do a search on the kit... There is quite a bit of information out there on the kit.
