Problem With Bov?

Keyword there - stock airbox.

You put a decent flowing panel filter into the airbox and you'll find that there is no really difference from that and a pod until your making some seriously big power.

I think Dezz did a back-to-back test Airbox & Pod (no cai boxing) on the dyno, there was a marginal increase in power and a skerrick in mid range.

However, the increase was so small that you would not notice nor feel on the street. The extra 2 or 3kw is dick all in the big picture for a street car.

And i would go on a leg to say if it was in a secenario with high under bonnet temps the pod would let you down noticeably

Basically for a streeter upto 250rwkw. Your better off with the airbox than a CAI/Pod setup if you look at the cost vs gain if your on a budget.

As it leaves money to be better spent in other areas

I found with the stock box the intake pipe would suck in and block under full load. Therefore this demonstarted to me the box has some restriction cos a pod does not do it at all. I found this to occur on the dyno at ~230-40 rwkw. You could replace the intake with a metal one, but your just masking the problem IMO. However a metal one is better anyway.

You could vent it better like some have done. But I CBF so I ran a pod.

I was suprised when this happened. but it did happen.

You're probably describing the sound from the stock BOV recirculating air on partial throttle openings to make your drive smoother. I guess you could hunt down an aftermarket recirculating valve that doesn't do this if you really want to keep the pod.

Hmmm... nice idea. Thanks - that might be the go.

Although I am starting to have fun with it now :P

when I first ehard the noise on friends car I though it was a BOV~~ the he showed me it's only th pod~~ sounds nice whats wrong with it~~

with regards having pod filter pipe going under the CAI box tray, I recon you'll get heaps of bug on there. Been considering it, I mean if you get some cheap ass $10 pod filter that's ok.. but if you get those Apexi $200+ and all the bugs splatered on your filter.. that's gonna cost heaps for maintenence..

Hey fellas

I just got my pod filter from Slide (thanks Aaron) and after installing it I've noticed something I didn't expect. Basically there is a really loud rushing air sound whenever I come on boost. I was looking forward to a bit more induction noise, but this is just embarrasing.

I've never put a pod filter on a turbo before, but on an N/A engine you just get a deep throaty growl and I was expecting something similar with perhaps a bit of a gushing sound when the BoV opened.

Is this constant rushing sound normal for turbos or is my blow off valve knackered?

Cheers guys

LOL embarrasing?

that hard/loud induction noise is pretty much what got me into turbocharged cars, specially skylines since they got very loud induction noise and you only need a POD to get it out of em :P

if you think thats a loud sound - come and stand near mine at 18psi with a 4 inch stainless pipe, and a GT3076 sucking at the other end..

Then you turn some heads.... Or maybe cause some people to dive for cover cause they think there is a cyclone coming to tear their house out of the ground..

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
