Forge Motorsport Bypass Valve?

I put in the yellow spring + a spacer last night and it sounded like poo this morning on the way to work. I can't describe the noise, it was a hybrid pssh + something else.

Really though, I've tried yellow, blue, blue + spacer and yellow + spacer and the performance difference is negligible. To me there is a slightly different sound though.

Blue or Yellow, no spacers is probably a safe bet.

100% Agree
 
Does anyone have this in their car that is otherwise totally stock? I'm curious to know how it feels with nothing but the FMBV.
 
It would most likely improve response and hold boost where ever its leaking, but It would be held back by the restrictive Airbox, probably won't be able to hear it either.
 
If you have the stock airbox, the noises probably won't be noticeable, but it does have a distinct sound to it.



EDIT: After looking around, you will be able to hear the new BPV, I don't know how audible it will be.

After driving a 2008 Dodge Ram Cummins Turbo 1000 miles this weekend (car from work while my company car gets a new non-leaking fuel tank) I know now that she'll never notice it since she only noticed the turbo in the truck when I pointed it out to her. Even after that she didn't really care, just wanted to listen to the radio. I think I'm in :)
 
I didn't realize what a difference the forge had until I took it off. I thought I put the stock on wrong or something there was so much difference. Its on right and forge gives you great performance for the price and if you don't like the sound, it is easy to learn how to stay off the boost and save gas mileage while you're at it :)
 
How long did it take to get to you? And I would like to hear your thoughts as well on the quality, noticeable improvements etc.. It would all be greatly appreciated! Gosh I just can't wait any longer.

I ordered one on Friday and I got an email saying it shipped out the same day. I should have it on Monday.
