Why Do Only R33's (turbo) Have The Pod-suction Sound?

Well fellas,

as the topic suggests... I've driven a few of my mates's R32's and have recent been driven around in a mate's R34 and for some reason - even though my mods and his mods are very similiar, e.g. BOV, FMIC, Blitz/Apexi Pod - how come only the R33's have the nice and aggresive suction and flutter sound as opposed to the R32 and R34 where close to no sound comes from the Pod?

I don't understand, the engine set up e.g. is pretty much identical?

Cheers,

SM. :whistling:

dude my 32 has more induction sound then i can poke a stick at. its almost annoying. even light throttle so its only boosting like 1psi will have a slight sucking sound more then able to be heard in the cabin. nothing out the ordinary either, normal pod/cooler/exhaust mods.

maybe your mates 32's and 34's are non turbo. :)

seriously though... dont know where you would get that . All have the fulli sick suction sound if there turbos and got a open exposed pod. Some pods will be louder than others but still...

my mates 32 has similar mods as my 33 and his is louder.. go figure

at the end of the day, who cares.

the suction sound can be affected by the filter itself, some are louder than others.

the suction sound can also be affected to what boost level your running, more boost, more suction, more noise.

The "flutter" sound is compressor surge, and that is affected by the setting of the bov. If the bovs spring is set hard, then its not going to release the intake charge as much as a soft set spring, therefore you will have more "flutter" going back through the turbo and out the pod.

Even though you and you mates may have simular mods, ie pod, bov, fmic, the brands themselves and they way the are setup can affect the noise

I have loud as shit induction noise while I'm still at 10mmHg!

You don't even wanna hear it when it comes on boost! It sounds like a pure animal if you're driving alone beside it.

Mind you, 3" stainless pipe from motor to filter helps with this... Then I must also have a "noisy" pod...

yeah metal intake piping makes a huge difference to intake sounds. The stock rubber intake absorbs quite abit of the induction sound, put a nice alloy or stainless pipe in place of it and you'll notice a nice jump in db's haha

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
