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

      R34 Skyline climate control unit transistor

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
