I'm also after a particular sound. If anyone's a fan of futurama it's like zoidberg "woop woop woop" heh heh.

It's sort of "wup wup wup" or just "wup" in a higher pitch. It's definately not a woosh or psst sound.

It was featured in a HPI dvd on a 4 door r32 with crazy rims and custom paint (from a K class car I think they said). It drifted around on the track and I believe the last thing they said was "lets see if the driver can keep the panels straight" or something.

Anyone know the one?

:)

AHHHH HAHAHAHA. Thats a good one. I was in class when I read that. I know what your talking about someonestolecc but i've never heard anything that sounded like that.

Possibly the most similar noise would the sound of a VL commodore with no BOV and a large intercooler which sounds like a CHOO choo choo choo....

yep thats what i was picturing

i started saying these out loud softly to try and work out what the sounds were then i stopped because im at work and thats just really weird, like keep your children away kinda weird

either way - my turbosmart sounds like a crisp CHI CHI CHI, im after a low pitch BURRRRRRRRRR which my mates gtr with a half plumback makes.

Just get an angry pigeon and put it in the engine bay, shut the bonnet. no one is the wiser. i think they have kits for it. If not, then gimmie a coupla days to catch one of those magic AP-S1 and ill do a professional installation for $45. Bargin!

BWAHAHAHAHAHAHA

i'll take one as well.

I dont know about you guys but im in the market for getting a BOV thats similar to the sound a WRC makes with its wastegate. Its more of a high pitch squeal than a conventional "WHOOSH" sound. ANy ideas?

lol.....

hey CC, u hit the nail on the head mate, that's exactly the BOV i'm after, been looking for ages and still can't find it....

anyone?

Yeah me too.

And for those saying it's pipe reverberation it's not - in the HPI video the BOV is visible to see it's got one, but not close enough to see what it's like.

It also sounds different to the reverberation VLs etc get.

Someone mentioned the wastegate on WRCs I think it'd be great to get my car sounding like them off-throttle, but I think the grumble is anti-lag so er... yeah I won't mess with that, although my 351 used to do it :P

If anyone knows what the wup wup wup one is please lemme know as it's the only one that would interest me :(

the vl pipe reverberation makes a low wuv wuv wuv kinda sound, but as cc said its probably not what anyone is after

Yeah i hear what ya saying. The WRC screach is what im after or somethign similar, but the pigoen squealing sounds very interesting as well. Might be worthe looking into that if someone gets more details.

my god..

The total IQ of this forum dropped 200% with this thread.

1.) bov's don't make fluttering noises.

2.) SARD R2D2 makes a single psshh release sound.

3.) if the car on the vid had a bov and made a flutter sound, chances are the bov was set really tight and wasn't opening.

4.) The standard VL sound is what you are hearing on all thse cars going woop woop or chi chi or whatever the **** you want to call it. it just sounds different on different cars.

the pitch of the sound, the length that it goes for, the speed of the flutter all depends on many variables..

eg..

turbo, ball bearing, non ball bearing, number of blades on the turbo's inlet wheel, their angle, the speed at which it is spinning when you release the throttle.

the intercooler pipes, diameter, length, material it is made from.

intake pipe, material it is made of, the length.

the WRC car's would make the same noise as a road driven W or EVO with the bov removed and plugged up, except with anti lag, it makes the sound different again due to the amount of boost. and lets not forget the 32mm inlet resrictors on their turbo's... all these add up to making weird and wonderful noises.

The sound from S14's and S15 with stock bovs is another one.

the reason they make it once you increase boost is that the plumback return line is too small and it can't vent enough back to the inlet.. this causes fluttering.

onec again.

THERE IS NO BOV THAT VENTS MAKING A FLUTTERING SOUND

It's possible, but never the less you're talking out of your arse.

That's obviously not what we've been talking about.

... Considering a WRC car and a road driven STI/EVO are a "bit" different I would imagine they'd sound different too. I also doubt the WRC cars have BOVs that are blocked up. Either they have em, or they don't.

The sound from S14's and S15 with stock bovs is another one.

the reason they make it once you increase boost is that the plumback return line is too small and it can't vent enough back to the inlet.. this causes fluttering.

You say that BOVs don't flutter. Here you say they do.

I guess it doesn't matter anyway because I have a s15 stock BOV and even with 20psi it handles it fine and goes a nice woooshkaa through my piping when it "blows off".

THERE IS NO BOV THAT VENTS MAKING A FLUTTERING SOUND

Flutter - noun,

Rapid fluctuation in the pitch of a sound reproduction resulting from variations in the speed of the recording or reproducing equipment.

If we take out recording and reproducing equipment for the sake of what the word is being applied to here I think you'll find BOVs do flutter. They just don't cause reverberations unless they're tightened.

So thanks for dropping the IQ 200% ... :Bang:

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
