ok so i got my hands on a GTR BOV and a bigger hose for the plumb back and connected it all back up just like the stock GTT one was.

all is well but when i come on boost say around 0.5bar maybe more (highflow turbo set to 1 bar) while still in gear and and let of the accelerator the car makes the normal psssh sound but it also makes a (very hard to describe) different noise also. kinda like a viberation noise but not quite.

ill see if i can get a recording of it.

but has anyone else experienced anything different with a GTR BOV?

im not having any other problem. car is holding boost fine. idleing fine. just the noise. and the strange noise is pretty loud too if your outside or have the window down.

help.

around 6seconds into the vid, does it sound like that? If i get it onto boost abit and then half throttle, it will do that sound. A mate thinks it sounds like a poo going down the pipes LOL

thats the sound hahahaha

thats it. like taking a bog with your ass sealed and you get that deap noise lol

any idea what it is??? if its anything bad? at first i though it was just the stiffer springs not opening enough. if i accelerate hard, change gears and accelerate again its fine. only whne slowly getting of boost it makes the noise.

hey ash,

long time no speak... i changed my gtst bov to a gtr one and also got that exact same issue! but i got rid of it..

i dont know if its the same for u, but the pipe i got to suit wasn't exactly perfect and I had a guess that the sound was of some air in the pipe as it was expanding or contracting... anyway, got a hose joiner to try to keep it more solid, and worked fine, not an issue any more!

can send u some pics if u want :ermm:

i thought that was normal? i swear there are some threads around about that and it turned out fine... my gtr bov is alot softer then my gtst one, but it does the job better so I assume its fine...

O great, another thread with somebody being worried about how their blow off valve sounds :(

oh wow thanks for your input...

vidospace the advantage with a GTR BOV is it holds more boost. only worth it if your running more boost then stock really as its a plumb back so its nice and legal.

alright, took some shots.

not the prettiest thing in the world, but she works well. definitely alleviated a lot of tension across the pipe.

im pretty sure it was a radiator hose bleeder or something, because I had to buy that gold blocking screw. was like 30 bucks all up and works fine.

Like air was blowing past the rubber pipe making in vibrate sounding like a fart. Another of my friends gets that too. Wonder why that happens. It atmo again as I got the sticker off. so meh

      If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.

      If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.

      MAJOR FUEL ISSUES 25det neo r32

      By MBS206 · Posted

      Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
