Bovs ...

[Jimlad]

Ok....

Am I right in thinking that it's the bov that makes the "Tssst" sound when changing gear ??

If so... I bluddy want one ?!?!?

I've been speaking with someone in Japan who says...

"The SQV and Super SQV are adjustable so will work with any generation as long as you can mount it."

Is this true ??

I'm gonna get on the blower to CRD about this and see what they suggest. Also want to talk to them about a Turbo timer.

The digital BOVs are from a company called Night Pager.

Easier to fit, won't mess anything up in your engine... will sound exactly the same.

[Bibbs]

The BOV WILL FIT any revision .. they have a mounting adaptor ..

But as I've said, cause they are AFM driven cars for the airflow, it can effect your fueling .. Mine is fine though ..

PM me if you want proper details or get on MSN ..

[Jimlad]

I want a BOV... I want a BOV....

"tsssst "..... yeah baby !

[Bibbs]

SQV - not a

tsssst

more of a "SKKKKRRRREEEEEEEE-tssss-tsss-tsss"

[KiwiMR2]

I want a BOV... I want a BOV....

"tsssst "..... yeah baby !

If you wanna sound intimidating get what I have:

so 150db is bluddy loud then..

most prob would knock everyone off their feet if you were driving along beside a pavement.. lol

[Bibbs]

Shame they can't get a 160dB .. every time you change gear, all the people within 50m are deaf ..

That'd be class :)

[Jimlad]

Proper "sunshine coaches" style ..

The loudest dump valve to my knowledge is a the Sard R2D2 @ 100db. The best part is that they have specific variants for the most popular cars/engines and have one for the ST205 3SGTE so I could a great bov for mine. Rev1/2 can still get a universal fit item tho.

But remeber the benefit of a recirc BOV is that the air discharge when vented back into the intake serves as a small boost of air to keep the turbo spooled up.With an atmoBOV this air just goes to waste. In a recirc its reused as a spike of air sent by the BOV and this air hits the turbo a split second after the BOV has opened helping spoolup.

So basically the recirc BOV better serves performance. An atmoBOV justs makes your car sound cool but at the possible exspence of affectin performance because of the difference in air that the AFM has already accounted for and measured has been vented to the atmosphere wasted.

I normally re-attach my recirc if im hitting b-roads and disconnect when im ricing about. But then again I wont have the fuelling issues you might regardless.

[nick_mcuk]

Jimlad....dont fit it if you have a REV1 or 2 it will run crap...i have an HKS SQV bov on mine and ended up buyung the HKS recirc adaptor.

The AFM on there gets confused whenit dumps already metered air and will make it run lean just at the point you are coming on the gas in the next gear!

DO NOT DO IT!

[Jimlad]

does it still sound good with the recirc adapter ??

[ZeroBlade]

does it still sound good with the recirc adapter ??

Lol, guess if u want this dump valve u'll havta get a rev3 engine transplant :P

heh

-Z

[Bibbs]

hope - the re-circ makes it quiet ..

mmmmmm....

Bibbs has no problems with his... so I may give it a go and see what it's like.

[nick_mcuk]

err he had a hybrid system his mate made where you can switch between the 2!

Trust me i have done lots of testing on this subject and if you have a rev 1/2 dont do it by all means have one but recirc it...I did testing on a RR and what it does to the mixtures is scary....

Besides its a very ghey and the noise gets on your tities after a while. Better to be stealth all day long!

And to answer your question..when you recirc it it makes no noise....and the car runs much better.

[Jimlad]

mmm...

but I want the noise..... :(
