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

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 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

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

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

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.

      Run it in open loop for now, and drop the frequency down. This lowers the resolution and requires more duty cycle to do anything, however good to troubleshoot.

      According to Josh, one of our local Americans, it seems the USA still can't get turbo systems quite right at a lot of places, so possible that they're not running great at all, but they've just not complained as NFI about getting it right...
