Post BOV needed for high hp applications

About the Adjustable BOV from stratmosphere, I took a look at the site, they are nice units. Will it work with a bigger turbo and more hp? I'm getting my Vitesse stage 2 kit and I was wondering what BOV I would need. Will I need one that vents into the atmosphere or can I still use an aftermarket unit that works like the stock unit? Thanks guys.

It´s always best to have a BOV that don´t went in the atmosphere. I went for a open one but now in afterhand i should have bought a closed one.

Check out the HKS SSQL BOV. This one and the Greddy may be the best on the market.

I Bought the Turbo XS open BOV, but that is just for the sound.

The one that vents to atmosphere will cause problem on a closed system

Get the one that works similar to stock.

Unless your stock BOV is bad, there is no need to replace it. I still run the stock one on my car.

If You don´t have a Map kit or stand alone system You have to go with a closed one as long if you have a catalytic converter.

The stock one can´t handle high boost and horsepower. There is cheaper alternatives to for example the Forge BOV. They works great.

Does anyone know if the HKS SSQ will fit under our hoods without major modification? i found a part on ebay that lets it vent back into the intake by replacing the little fins with a pipe.

Hi,

The SSQ can be ordered with a closed application to.

It will fit under the hood but You need to attach the adapter to the BOV on the IC hard pipe. It will not take any silicone hose.

The best thing is to manufacture a new IC pipe (not expensive) and to attach the fitment to the BOV on this one.

Regards

Hey, Thanks for the replies guys. Since I am going to be getting a MAP with the kit, I don't know. I think I'm going to go with the HKS SSQ. I would like to have one that doesn't vent into the atmosphere so it will reduce lag. Is there REALLY a noticeable difference in lag between a BOV that vents into the atm, or one that vents back into the system? Thanks again.

I can post up pictures later, the pipes is superb made. As long as you stay in the 2.5" if you go bigger the turbolag will not meet your satisfaction due to all the air that have to be pulle thru the pipes.

A Swedish exhaust company made my pipes and they are one of the best producers of exhaust system and this sort of applications in Sweden. Why go with original when you can have a polished good looking piece under the hood?

Pictures will come soon on my website.

"use two of them. people use the 993 units but forget that they are only meant for 200hp worth of air."

How do you use two of them?? Is it really neccasary to run two?

Are BOV based on hp or amount of boost??

i.e .Could be running 200hp with 20 psi or 400 hp with 10psi Which is the determining factor, hp or boost???
