Plumb Back Blow Off Valve

[dd4321]

Since petrol price is skyrocketting, can't afford to let my R33 keep running rich, therefore I am thinking of getting rid of my HKS SSQV atmo BOV. Can anyone recommend a good plumb-back BOV? Also, perhaps a dumb question, but would plumb-back BOV make flutter sound? I note that there have been some arguments that the 'flutter' sound is actually made by air bouncing back to intercooler - doesn't really make sense to me though...

Cheers,

DD

Why not put the stock one back on?

Anyway my GReddy Type-S can be plumback and yes it makes the flutter sound - more to do with the FMIC than anything though.

Does plumb back help fuel econemy? That been tried and tested?

Seems my R33 GTST is using alot of fuel.

BOV

3inch exhaust (all the way)

Pod filter

How many K's do you get off a tank mate? I usually refil 50L every Tuesday night (Petrol at its cheapest) and that lasts be about 425 - 450 K's. Still takes around $75 to fill tho.

All I've got for mods atm is a Deceptor Pro BOV. Might try running it Full plumb back next week and full atmo this week and see the difference, will Keep you posted.

I've onlt had the car a week. Havent worked out kms/tank yet.

But i see the needle dropping a bit too fast. Of course, the first few days i was giving it quite a bit.

Does the BOV really blow fuel out ?

I notice when i'm city driving in 4th, doing 60kph, the rpm's show about 2200.

Does that sound high?

Mate you shouldnt be worrying about fuel economy, yours is awesome already.

I feel sorry for the guys with stockers who get like 250-300km's/50L if that.

[Liiger]

Yeah but some ppl say that they can get 500K's+ . Would love to get that. Would a 3" turbo back exhaust and Cold Air Intake help too yeah? Or would that eat up more petrol os of more air?

Has anyone get one of these plump back adaptor? Is this original HKS item? How much? Also, dumb question, does it still make any noise?

[skybee 93]

3.5inch all the way

BOV = POS. Waste of money. Run stock and save hassles with stalling and fuel.

If you want your car to make sounds then fit a pod...

[RBFIRE]

yea, i bought it,

its genuine HKS, I bought it for $70.

and yes you still can hear it.

that is just your opinion!

some ppl dont like stock BOV.

Pod noise is realy one of the anoying sound i ever heard.

I got no issue with stalling or fuel with HKS SSQ,

well that is my experience anyway!

[Madaz]

yeah i get 300-350 on a tank but boost it alot too POD, factory blow off factory turbo on a RB25DE engine had it converted (by previous owner)

i like the sounds a POD gives your turbo, i wouldnt get blow off to scared to get it defected

I forgot to add backfire...

Anyway I was crazy for atmo BOVs etc... until I saw the havoc it was causing with my car... maybe I am harsh but for the money I wasted on buying/installing/removing the BOV... would I ever do it again? no thanks!

um.....

[FSTR32]

SSQ BOV's are rubbish...go for something like the turbosmart supersonic stealth version. Awesome BOV whether u plumb it back it or atmo it. Flows alot better than the SSQ (less lag) plus its an aussie company. Just my 2 cents

[R31Nismoid]

Less lag ?

[dd4321]

Just bought the SSQ plumb back kit from BD4, genuine HKS item for $35, but just the nozzle though. Still trying to figure out what kind of plumbing I can use to connect to the intake pipe.

In the mean time, I tightened the BOV adjuster, making the BOV not to vent on low boost. Now I can get flutter and whistle noise at the same time... sounds better than before I reckon. But by doing this, will I harm the BOV itself or the turbo?
