Thanks AlexCim for doing some research into heater core's for me, here is his findings:

My wife loves the stagea, but if there are no parks she can drive into, then she goes and finds one.

I think the stall issue is more the fact that the stock ecu is expecting the rush of air and richens fuel ratio's accordingly, and it just puts too much fuel in and floods it I guess? I fail to see what spring rate you set your bov to will change this, because that air is still not being fed back to the intake of the turbo. Too tight and the bov wont open and the air will go back through your turbo, making the intake side of the turbo spin one way and then the other and so on untill the pressure is equalised. This is what is happening when you here that "cool" flutter" sound, it's actually really bad for the compressor wheel, or so I have read........? Well at least that is what I "think" which could be totally wrong, as I am not a mechanic, nor a turbo engineer. It's just all the stuff I have read from other people posting, mainly here on SAu.

Yeah thought I'd post it, then there is two places people can find it

And before you go saying that you cant find it: |------------------------+------------------------+------------------------| |Engineering Instructions|Vehicle Accesories | | |------------------------+------------------------+------------------------| Date Of 17/04/2 Date Of 17/04/20 No VA.06.04.0 Replaces/A Issue: 002 Effect: 02 : 2 mends: It has come to the notice of the Vehicle Safety and Industry Reform Section that a common modification to vehicles equipped with a turbo-charger installation is the fitting of an intercooler and a blow off valve. Forced induction methods such as turbo-charging or super-charging have the potential to substantially increase the power and performance of a motor vehicle. Apart from the engine itself, turbo-charging or super-charging affects four main vehicle systems. These are exhaust emission controls, vehicle noise suppression systems, braking system performance and driveline components. Option 3 of Section LA of the Code of Practice (Light Motor Vehicles) permits the fitting of turbo-charged and super-charged engines to light motor vehicles in accordance with Schedule B of Section LA. A part of this approval requires that a “Safety Upgrade” of the vehicle is implemented in order to provide for the increase in vehicle performance. Braking system performance and driveline components are addressed in the upgrade requirements. Additionally, the modified vehicle must continue to comply with the Australian Design Rules relating to emission controls and noise levels to which it was originally constructed. Whilst it is recognised that a large number of the vehicles referred to in this instruction are factory fitted with a turbo-charger or super-charger installation, considerable modifications are carried out to install the intercooler, blow off valve and associated pipe work. The installation of these components is acceptable, if fitted in accordance with good engineering practice, i.e. it should not significantly affect the noise and emission levels of the vehicle. Installation of blow off valves/intercoolers are regarded as accessories and do not require approval under Section LA of the Code of Practice (Light Motor Vehicles). However, a number of vehicle owners are installing additional “whistles” to the blow off valves (or alternative blow off valves with whistles). This procedure has attracted Queensland Police Service attention. A number of infringement notices have been issued to vehicle owners for, it is understood, excessive vehicle noise. Whilst the blow off valve in an unmodified state is of little concern, valves fitted with a “whistle” attachment can be quite loud. The Transport Operations (Road Use Management – Vehicle Standards and Safety) Regulation 1999 requires that a person must not drive a motor vehicle on a road if the vehicle’s silencing device has been modified so as to reduce, or be likely to reduce, the effectiveness of the device. As such, the silencing devices fitted to these vehicles have not been modified and the noise is not attributed to the exhaust system. The Transport Operations (Road Use Management-Road Rules) Regulation 1999 raises issues in relation to devices fitted to motor vehicles and excessive noise emitted from motor vehicles, and is as follows: Making unnecessary noise or smoke S 291 (1) A person must not: (a) start a vehicle, or drive a vehicle, in a way that makes unnecessary noise or smoke; or (b) wilfully start a vehicle, or drive a vehicle, in a way that makes unnecessary noise or smoke. Example of subsection (1)(a): Driving a vehicle in a way that causes noise or smoke because of: (a) disrepair of the vehicle; or (b) the way the vehicle is loaded; or © the condition, construction or adjustment of the vehicle’s engine or other equipment. Example of subsection (1)(b): Driving a vehicle in a way that causes noise or smoke by wilfully and unnecessarily causing the wheels of the vehicle to lose traction and spin on the road surface. S 291 (2) A person must not drive a vehicle to which a noisy instrument is attached or on which a noisy instrument is used. S 291 (3) The driver of a vehicle or a passenger in or on the vehicle must not: (a) ring a bell or sound a horn, except a horn or similar warning device under section 224; or (b) play or use a noisy instrument. It would seem appropriate that the Road Rules legislation is relevant to vehicles equipped with these devices and which are modified to allow excessive noise to be emitted. The Queensland Police Service should be utilizing the Road Rules to enforce the issue, and, the owner would need to remove the device to avoid continually being issued with infringement notices. Inspectors Action: Transport Inspectors are advised not to issue Defect Notices solely for the reason of a vehicle being fitted with an intercooler or a blow off valve. Any enquiries relative to this matter may be referred to the Road Use Business Management Group on telephone number (07) 3253 4851 or (07) 3253 4778. Inspectors should telephone (07) 3253 4778 or 4308 for additional information.

If you buy an aftermarket plumb-back bov, then it should sould exactly the same as your stocker. Now about the legality of aftermarket BOV, here in QLD TORUM (the legistlation that QLD police are governed by) states that anything that could release petrol vapour into the engine bay is illegal, so technically a fully plumb-back bov is fine, and all types of atmo bov are illegal, because the air that is vented "could" contain petrol vapour. If you do some searching in the qld section I posted up the whole sections of TORUM that covers the legalities of pods vs airboxes, bov's and underbody lighting.

That is such a cool page, look at all the goodies you waste *cough* I mean invest in

I think they are either built fully plumb-back or fully atmo. But you can buy adjustable ones, like the GFB Stealth, but they are not cheap, about 2yrs ago when I looked at prices a brand new stealth was worth around $500......... For something that gave you no real outcome, other than a bit of noise, it's not a very good investment, or so I thought. I was just lucky that when I bought my stagea, it came with one. I "tried" on my old r33 to make the stocker bov dual, but it was just too much of a problem, mainly with stalling issues, so I gave up and just went to fully plumb-back.

I am guessing that the "Hard" and "Soft" settings are the spring setting, meaning that the harder you set the spring, the more pressure is required to make it vent. There is a lot of stuff on SAu regarding this subject, and the only two ways of getting rid of the stall, to my knowledge, is get a dual plub-back/atmo, like the stealth which you can set to both atmo and plumb-back and set it to varying degrees, from 100% atmo, 0% plumb-back, through to 0% atmo, 100% plumb-back. OR Get either a plumb-back OR Get a atmo venting and get some sort of aftermarket ecu or piggyback ecu to tune the stall out.

Well when I dissconnected the plub-back on my stock r33 bov, whenever the rpm dropped below ~2k it stalled. When I set my stealth to anything more than about 80% atmo, I got the same issue re-appear. But I was told that if I wanted to keep it like that, all I needed was the lower rpm range remapped on the poer-fc, and that would fix the stall issue. Instead I just set it to 100% plumb-back, works fine and no "wake the dead" PPPSSSHHHTTTT on gear change now

Yeah the very first meet you organised ado, and the crazy russian drove all the way from Brissie for it. Where we all put down people who dont let thier motors warm up before giving it heaps, and then nearly everyone chucked a skid leaving How close did that, "he dont care cause a v8 twin turbo next week", come to taking out bowser 12, I was so ready to take the bolt eh!

They cost a lot, we looked at doing this when I was a part of the SAU Qld club, Erin did a lot of research and it was gonna cost a fortune!

Still you did not stop and consume the heart of the owl you hit! AND CONSUME ITS SOUL!!!! http://www.skylinesaustralia.com/forums/in...94&hl=glowworms BAHAHh HAhHA hAHHHAH ah haHAHhah HAaaa that was awesome, you pushing me to lose mindflux and then him carrying on like a girl when we stopped And who could forget that flacondore wagon that "tried" to do a burnout in the parking lot at mermaid beach petrol station NA_R33 to 13yo pertol skanks - "No girls, these arent skylines, they are Excels with Skyline bodykits" 13yo pertol skanks - "Wow they are cool body kits..." Where has MJ dissapeared too?

Hey I have heard that this has worked in the past.......

Stagea's make great tow cars Blacky has one very lucky owner there! Well done!

LONG LIVE THE ALFA!

Just take a lot of smokes, and if a copper comes over, everyone quickly take a smoke out and light it and smoke like hell

Looks nice I searched for ages to try and find the same sort of design but in 6 spoke, couldnt find anything available.

Mine looked worse after 9hours of night driving up from Brissie to Rocky! Might be the mountain air, I always copped a lot of bugs running up and down where Hugh lives, esp coming down or going up the goat track

Same as mine, if you want noise then two clicks from fully atmo is the furtherest I got without having stall issues, if you want no sound then it works just fine set to fully plumbback.

Stock RSFour-V+S It's slow

Dust off the flag Smooth!

Where does warwick pitch in....? meh musta missed it, anyway deleting all this crappy talk about cash in the thread, it is meant to be about the event!

he he he raws/dotars/sevs/etc you all know what i meant

So maybe the funds needs to be forwarded to slip so that he can get his car going and attend this event?
