Hiflow Turbo Sucktion Noise

[RamR33]

Hi guys,

before ppl say dont worry about the sound or as long as it goes,im just trying to understand still why my hiflow turbo which is a pu hypergear hiflow turbo .82 doesnt have loud sucktion noise hardly at all like my stock turbo.

i have an aftermarket b.ov plum back,3 inch metal intake pipe and drift pod.same as wat i had on my stock turbo.

the car pulls fine been on dyno power run but not really tuned full on.it does make a slight flutter and the pssshhh sound from the bov but at almost fullboost/full throttle.

theres hardly any sucktion sound as i thought this turbo being big and all would sound awesome.the minimal sucktion sound ive noticed does sound a lil rough like shhhrrrrr not that clean loud type.

is there some problem with my set up to this turbo or maybe thats how they are......

Does anyone have any experience on these turbos or how they sound cause doing my head in lol at the moment cause feels great but doesnt sound rite....

Spooling later? /guess

Wouldnt worry bout the sound if it drives good mate ive found the stock turbo induction noise to be quite loud. Ive gotta Garrett Gtx3071 on my car and i was bit pissed like you initially as you can barely hear my turbo compared to the stockie and its a 560hp turbo lol! But enjoy the stealth sound mate as it doesnt attract the wrong attention

I've got the ss2 hypergear turbo, it sounds awesome, low deep flutters but no where near as loud as the stock turbo.

What about the actual spooling/suction noise from pod is it loud sargerx8 on yours when hitting boost? i removed the b.o.v and hardly hear any flutter at all or suction noise from pod ...

what intake type pipe and pod do you have ?

[SargeRX8]

I can definitely hear it but the stock turbo is louder. I've got a metal intake pipe with a Apexi power intake.

Its not a big turbo

But not all turbos make loud noises. Just for some reason RB turbos make ridiculous suction noises with a pod. I guess its the shape of the wheels idk.

HKS turbo's make mad induction noise

i just thought hi flowing/bigger wheels would just make it sound great but hey the performance improved by 20rkw on stock boost to stock boost from the factory turbo so i guess its doing its job

i got the rb25 turbo on my rb20 and its really noisy, sucking and hissing, probly the wastegate slightly open when not on full throttle,

When i put my foot down i cant hear the turbo hardly at all, just a big pshh when i take the foot off.

Try driving around with less throttle. or if that doesent work you could set it up shit like mine with no computer upgrade or boost controller.

Split dumps can sound cool too, i got a cheap and nasty one (JJR) and it has a stupid flange bit which doesent fit and has to be ground back so it makes a whizzing sound when the gasses go around it.

Im hoping to eliminate some of the noise, its ALL THE TIME and im over it.

[RamR33]

Yea i do have an upgrated ecu and boost controller and still nothing...can hear the turbo spool slightly when i put my foot down and a big psshhh release from bov. sound like n/a lol

everyone is over the sound/noise spool and i wanna be over it too haha...maybe get it checked out by someone just incase.

My Garrett 2871 is pretty loud all round.

If you want noise, HKS t51r KAI, you will have a jet under the hood lol!

I think it's just rb's stock turbos are loud a prob the loudest standard turbo I've ever heard.

The new turbo will be more efficient and the blades will be more aerodynamic etc and it will be doing a better job with less air/friction resistance hense your power increase and less noise.

Wouldn't worry bout it mate.
