Blow off valves are blow off valves. Purchasing an aftermarket brand name BOV doesn't always mean its a quality product. Leave your stock one on unless its leaking. There is no performance gain in adding an aftermarket one. Save up for a worth while modification that you will benefit from.

Sorry didn't answer your question very well. Yes the Bosch BOV's are decent. I had a friend with one installed on his VL Turbo and it was loud. Did everything a BOV was supposed to do.

Two friends of mine with MZ20 Soarer's have the Bosch BOV's installed.

One of them, if you hit a certain rev range and hold it, the BOV will sound like a continuous Hoot from an Owl.

I did a search and it seems this one is good for low boost.

It doesn't sound all that good though.

Where can one get this? I want it to plump back.

How much boost are they capable of sustaining? and are they really $50? If so, where from?

I bought one from AutoBarn in Brisbane. Apparently* they hold up to 15psi and are quite reliable.

However, they are quite loud. (unless thats what u want)

[Guest RaBZ3174]

yea i heard they hold like 15psi im not really interested in buying one just wanted to know if they were just as good as any other one i personally like my stock one with the cooler sound..sounds awsum

the stock bov is good for 18psi so y bother with a new 1 that will only hold 15psi?

and u get what u pay for, for $50 u wont be getting much

boys boys boys. The Bosch BOV is a great blowoff valve, CAPA actually use two of these on all of their aftermarket Supercharger kits for Commodores, Falcons & Nissans - 6's and 8's...

Volvo, Saab and even some other european turbo cars use these from the factory...

I will only say this once: A BOV will only work best at holding pressures when it is mounted in the proper the location, (before throttle body is best) and whether or not it's vacuum line is receiving the same boost signal as the boost pressure that is trying to push the BOV open... This will ensure the BOV remains shut (no leaks) when both sides of the chamber have equal pressures. When you let your foot off the pdeal, the boost signal travelling along the vacuum line suddenly disappears (closed throttle, no positive pressure in the manifold) forcing the BOV open by the boost pressure trying to get past the throttle butterfly(s). Simple. No S*** i hear you say...

Well most factory BOV's leak because they are usually located after the turbo and before the intercooler, therefore when you increase the boost, the pressure drop across the restrictive intercooler core causes a lower than expected boost pressure to travel along the vacuum line (from the manifold) to the BOV, which causes it to leak.

The Bosch BOV is going to be exactly the same as your original BOV, but offers people an option when they are going to have a different inlet piping and want to ditch the stock setup. It's more functional rather than w**k value compared to other aftermarket valves, i reckon. Can be either rigged up to vent atmospherically or be plumbed back to the intake.

Part# 0 280 142 103 and can be bought for under $50 if you're lucky and know someone who has an account with Robert Bosch..

LOL - that hooting noise...

[predator]

sounds like a pigeon juz got caught in your cooler..

[TTT]

to have the bosch bov venting to atmo without an AIR FLOW METER's car stalling, you will need to modify the bosch bov with a one way valve.

otherwise you MUST have it plumb back (unless your car doesn't have an air flow meter.)

if anyone wants details on how to make the bosch bov able to vent to atmo, I can post a link.

[S13 Silvia]

What other cheap BOV's are there that do the job but can handle more than 15psi?

[TTT]

I have a brand new GFB hybrid (half plumb back/half atmo vent)

for $200.

they retail at $320

[SHUTO-BOY]

BOV's sound different with different boost

[S13 Silvia]

How much do you want for that cooler that's linked in your signature? and do you have any pics of the GFB BOV?

[TTT]

cooler.

the front mount is up for sale for $320.

640mm wide x 170mm high x 60mm thick (width includes end tanks)

bov is below..

I just found these are $329 direct from GFB..

[T0nyGTSt]

If you really want a cheap bov, get the OEM and mod it as previously stated. If this Bosch falls thru I might do that.
