I got a Greddy RS BOV for free and I Installed it on my Stock Turbo Evo IX and I'm wondering is the Bov any good or is the stock one better? How much boost can the RS hold before it starts to leak?

 

It's good in my opinion. I'm sure it will hold well over the stocker. 30-35 psi if it's set correctly. I would recirculate though if you can.

 

if your car is stock don't bother with it....


on second thought...just don't bother with it

 

stock or aps. i would put the other back on

 

You have an EVO9...its 10x better than that POS. I just got rid of a GReddy RS that the previous owner put on my car. ALLLLL, I had was compressor surge. You should know this by now with all those mods in your sig, unless you bought the car that way.

 

I had an HKS BOV on my car but went back to stock and the car runs much better.

 

I do have it recirculating and the car runs the same with the greddy and stock i didnt feel a difference besides hear a differnt sound. I dont feel the compressor surge ur talking about.
