i want the flutter noise thru my pod/airbox/air intake...whatever u want to call the setup.....

all i have is mass suction and then a massive whoooosh sound......but i want the flutter sound to come out instead...as it sounds better and all...but im not sure on which pipe i need to block or what exactly i need to do to the stock bov and piping to achieve this....

easiest way to do it is get piece of 2mm alloy sheet and take the blow off valve off where it mounts to the cross over pipe and place the pipe on the sheet and trace it out and cut it out and drill the 2 screw holes in it and place that in there instead of the gasket. That way it still looks like a gasket but the air cant get to the blow of valve and gives u the flutter sound.

thts the dumbest thing that u could do as it will f**k up ur car the way that it makes the flutter sound is by instead of releasing the air thro the blow-off it sends it back into the turbo and that will make ur car run lean u'll get shit fuel consumption and constant staling.

if u want the noise then get a screamer pipe any of the tuning shops will be able to do it its a lot better then blocking of ur blow-off.

ive got a turbosmart mega sonic BOV and apexi super intake pod filter on my r33

i get the flutter and a stadard bov cshhh sound. changes depending on the boost it hitting. but with my flutter, i have free reved the car while watching the piston in the bov and see the piston bouncing to make the flutter. tried putting a plate where the bov is and it sounded shit.

so id say get a aftermarket bov and a pod filter. unsure of other ways but mine has done 0 damage.

i had the stalling problems but cleaned my AAC valve (DIY section) and increased the idle to around 800rpm and have no problems with stalling anymore.

No offence, but your an idiot and have no idea what your talking about.

It won't make the car run lean, it actually richens up the fuel mixtures with a blocked off valve on the stock ecu, so will run rich for that split second.

What the hell does a BOV and screamer pipe have to do with one another? They are completely different things. Do you even know what a screamer pipe is?

Mate do a search on "flutter", its been covered a million times.

Thread lock?

      Original window sticker?

      By Celticsfan03 · Posted

      Hey everyone. Is there a way I can get the original window sticker (maroney label) for my 1995 R33 GTST? I doubt I’ll be able to ever get it but it’s worth a shot to ask

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
