My 32 has twin blitz blow off valves, which are perhaps a lot more audible than I would like.. see, Adelaide is known as the defect state.. and I can't afford to refit the entire car back to standard if I get caught.

Q) how loud (if any noise) are the standard gtr blow off valves? considering I have twin pod filters.. it sounds pedantic, but the nazi cops love seeing imports to fill their duty quotas.. and if they hear any light 'swooof' they'll slap a sticker on my car for a full inspection. As unfortunately is the way here; your guilty till proven innocent. :)

If you want, check out the outstanding ‘regency experiences’ thread by Steve in the Adelaide section to see what we face.

The stock BOV's do make a fairly audible "chooooof" noise when fitted with pods. They are however perfectly legal as they do plumb back to the inlet. If the cop is being an ass, just try and confuse him by saying ltos of big words like "the pressure release valves are perfectly legal, they are recirculating back into the intake of the engine" etc. Most of the time (in ACT at least) they give you the benefit of the doubt.

Cheers,

Though if I fit the standard blow off valves back on (as my car is WAY too loud now) I've heard about issue's with them leaking. I'm currently running 1bar, and would like at some stage to run a tad more.. can you effectly prevent them from leaking when raising boost or even running what I am now?

Generally you will be fine unless you make a point of "venting" within hearing distance of a police officer/car.

Luckily, aftermarket bovs on a GTR are not visible in the engine bay, assuming of course that you have your aftermarket bovs fitted in the factory location.

Police normally have a go at you for what they can see. Out of site out of mind.

Theres cars making in excess of 500kw using the standard blow off valves, they are really good. However, you can occasionally get a dud one which does leak...

    • Long time no random post about shit. So I went down this deep deep rabbit hole of battery storage for the home, ended up locking in a 41.9kWh Fox ESS EQ4800 with 9 units stacked. Battery uses Lithium Iron Phosphate, similar to what you find in those deep cycle boat/caravan batteries. And yes, why did I go with a cheapie brand and not like Synergy? simply because I don't plan to stay at this house for more than another 3~5 years.  The entire install, DC coupling (removal of existing invertor, connecting the current 6.6kW array direct to the battery invertor), new 8kW invertor is $6K all up (after all the rebates etc.). Going with this lot: https://www.aussiesolarbatteries.com.au/ It did seem a bit too good to be true, however seems like the Whirlpool community has vetted it and when it comes to this kind of stuff, they seem to be all over it: https://forums.whirlpool.net.au/thread/9pxj8482?p=38   I've requested for the battery to be installed outside, next to my meter board and not inside - rather have it combust and ignite outside lol.    
    • In Vic it would be a defect regardless of whether or not you cut a hole in the sheetmetal for the return pipe. The rules in Vic are shitful, and are generally interpreted as you can "make 2 mods to the intake system". Putting an FFP and an FMI onto it will almost certainly be seen as some huge number of intake mods. You really need to speak to an engineer before doing this stuff in VIC.
    • planning a r34 rb25 de+t with some other work, rather just have it done in a shop due to space limitations any recommendations? I have most the parts already I seen online Moore Performance and DR Drift any advice appreciated thanks 
    • I’ve read the previous posts so just looking for latest information on how people have dealt with front facing plenum is it a defect etc or didn’t pass roadworthy or was it not noticed? Have a r34 and deciding if I should make a hole on the driver side or not.  I know some people have said blitz return flow but I might get rid of the stock intake down the line for a plenum so I rather set up for that now plus I already have a standard Intercooler. Car is mainly stock  Thanks. 
    • Actually, if having and keeping the stock ECU is the plan, the correct answer is to put Nistune into the ECU and improve the situation, not just look at it.
