Forge Bypass Valve Owners!!!

[Adammazda06]

i have the forge valve and have been very happy with it. i was using the blue spring which most people suggest, but i installed the yellow today just to see the difference. if i want to put in a shim, what side does it go on? bottom or top?

Is your car fully stock other than the vavle?
What improvements did you notice, if any?

i have intake, cbe, and motor mount. the blue spring builds and seems to hold boost better than stock. the yellow spring that i installed today drive more like the stock valve. still seems to hold and build boost better than stock, but drives smoother than the blue spring. i will drive with the yellow spring for a week or so and the install a shim to see what that does. yes it sounds cool, but the butt dyno feels a difference in the way it drives. i am selling my car for a white one and the only part i am taking off of it is the forge valve if that tells you anything.

Why not keep the other parts too; CAI and motor mount...?

The shims go beneath the spring. You can shim a soft spring to the same crack pressure of a stiffer one but it will have different characteristics as it compresses.

Hey Patty, will this piece hold stock psi with heavy bolt ons. For instance,
3"TBE, CAI and upgrade TMIC?

It will "hold" pretty much any amount of boost. As to whether or not your boost will remain the same... from what I've been reading the factory valve is so bad that bolting on ours will "raise" your boost.

Which isn't a fault with our valve, it just brings to light the inadequacy of the OEM piece. I just had to refund someone for this as he couldn't comprehend that the problem was with the stock unit and the HKS that he had on the car (with ours he was running out of fuel, presumably from the factory fuel pump not flowing enough).

Valves cannot raise boost, they can only lower it. In this instance the car as delivered from the factory is equipped with a valve that lowers boost and ours fixes that problem...
