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....

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

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 ?

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.

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.

    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option
