No Induction/suction Sound Why?

[RamR33]

I have no induction/suction sound with my hiflow PU turbo why is that..have 3inch metal intake and podfilter and nothing like my stock one but car goes fine.

any ideas...

thanx.

Turbo cars don't suck air like na. You can always hear it on a na. My rb20 don't make noise and every other turbo car iv been in don't make the sound y do you want it when you can hear the turbo spooling much better the gay induction noise

[RamR33]

na dnt wont the sound just thought from my stock turbo was like shhhhhhhhh wen on boost and my bro car put a bigger turbo on his n does it so just thought something up with mine but every turbo/car different I guess

Just the turbo spooling mate nothing to worry about

I would still expect it to make some noise. What filter is that on there?

[theponyremark]

Put a mesh filter on and you will get it.

What do you mean turbo cars don't suck air like N/A's? You don't think that turbo is pulling in extra air to flow enough to create pressure? Every single person i know with a turbo skyline and a pod filter makes a hell of a lot of induction noise.

If it has the standard air box and panel filter it will make minimal noise

saas filter i have on and tryed k&n pod and really nothing but just a lil bit like if i go past a car on the side u can hear it but very faint and the flutter is low as,but no where near my stock turbo which is strange cause i used the same pod and 3 inch intake and had a killer induction/suction sound.

Dont think i need the mesh one to get it cause my stock turbo didnt need it,only diff with this turbo is its hiflow and bigger and would think it sound awesome or better then the stock skyline turbo.

just strange that it would have full on induction sound on stock and not on a hiflow bigger one

could it be the plump back bov or something like that but wouldve been the same as the stock turbo...

The na motor sucks the air in and dosnt get compressed and you can hear it a lot more plus engine noise a turbo sucks air then compresses it hence forced induction its a totally different way of induction tell me how many turboed cars drive around having that na intake sound (really drowny) rather then ssshhhh (air compressing)

I also have a 3 inch alloy intake with a pod can hear it when bonnet is up and sitting right next to it but otherwise it's quite. Remember noise is caused by friction and vibration.

[markdem]

i would assume it has something to do with less turbulence. more turbulent airflow probably makes more noise. i think quieter would be better for your engine

I was more focussing on the fact that you said no turbo car you know makes any induction noise, where as all the people I know with turboed cars that HAVE pod filters make plenty of induction noise.

Noise comes from the blades on the turbine cutting the air basically.

Tell me how a turboed engine is not "sucking" in more air then an NA, this goes against the whole point of forced induction. Your putting more engine into the engine, its not just appearing in there magically, its getting sucked in there. NA induction noise is different but unless its a V8 etc, my old VL Calais had a Pod filter and barely heard any induction noise, Where as my Skyline with the stock turbo, stock piping and my HKS Turbo and custom piping both make/made induction noise.

Video evidence

OP: If your car is boosting and running fine then I dont see it having any problem, Just thought it was a bit strange that there was no induction noise

Yea car is fine, boosting fine np there,just thought everyone with hiflows has it so just wonderd why mine didnt thats all,maybe cause its a big turbo thats why....cant complain if its running nice.

I'm not saying there is no noise I'm saying it's a totally different with noise and how it sucks air. Some turbos spool totally different my td06 spools quite loudly with minimal intake noise. We are arguing over such a stupid thing all I'm stating is a na motor sucks air totally different to a turboed car and yes the compressor wheel makes noise as it is compressing air in the (compressor housing) and forcing air into the motor. If you have intake noise great I don't I just hear my turbo spooling end of argument you have induction noise I don't who gives a f**k really? The bloke was worried if this is something wrong and the answer is no his setup is fine can we agree on that atleast

If you want induction noise/whistle, than get a turbo with a shrouded comp cover, ala GT3076/HKS T51R/T88-38gk etc

Think we might just be on two different pages here, hence the confusion

but yeah your right, its a pretty pointless argument and I probably should have left it at the first comment lol

Interestingly but, my HKS GT2835 KAI seems to make alot more noise with the anti surge slots blocked off then with them open. Probably because the air has nowhere to go once it gets into the anti surge holes and creates more of a whistle. Still a disapointing turbo so far

[Bsa]

Ill try and get footage of my induction noise vs turbo noise. My theory may be wrong but the more flowing it can be the less noise there is because there is less friction

[RamR33]

Im happy its quiet until it hits full boost then i can hear the turbo SCREAM lol :

Appreciate the advice guys...
