seriously? I was at the tuner yesterday for 5 hours.. sure it must be a dream loll I just do not brag about my setup on the internet like some of you. I have nothing to prove and couldn't careless if you don't believe me.

but for the people really interesting ( because, yes I actually got 3 pms regarding this) about the -9, yes its possible ot achieve great number.

and here, we do not run E85 ;) we run 94.

Lol, you did brag.

Considering what sean posted, then you should get ahold of some e85, better than that 94 stuff you boys seem to run :P

dont laugh, my mate is making 286kw @ 14.5psi with gt-ss

Yeah on my built motor i made 280rwkw @ 1bar as well

End of the day mate -9s aren't going to flow 380rwkw @ 18psi, that's the simple truth.

If you really "do" have that power, take it to the strip and run near 130mph.

I bet you don't get any better than 124mph :)

True, I also referred back to the dyno comparisons spreadsheet on here and the -9's (GT-SS section) average at 303.1kw at 18.3psi which is exactly what I'm aiming for.

Maybe Cobra was running ridiculous boost? Some guys get around the 330-340kw mark with 22psi....but even that is still 40 odd HP short of 500. Not sure how far the -9's can be cranked but if you can run R33 N1s up to 25-26psi then I'm sure you can do that with the 9's as well....and that might be getting you quite close to say 360kw even though there'd be more heat created than anything else....guess it depends on where the -9's sweet spot is.

There'd always be some people out there who push parts to or past their limits....like Xkalaba and his ceramics :yes:

Already did. Last intervention in this thread.

I'm just trying to help out the folk considering buying the GT-SS and all I get is whining and '' your a liar'' i don't believe you'' . Well, unless you pay the plane to ship my car and me to australia, unfertunately, you will never see me rollin on your drag strip.

Look at some japanese setup, they can achieve 600whp with gt-ss.

Jing R34 GTR

http://blog.nengun.c...26-tuning-world

The Jing R34 GTR has been slightly modified with Tomei and Reimax internals and two low mount HKS GT-SS turbo's. Generating 1.3kg/cm2 of boost and producing 467ps this GTR has been perfectly tuned for the street. Volk Racing CE28N wheels cover Brembo Monoblock brakes and Ohlins DFV suspension.

The concept from Jing was to retain the standard engine and easy maintenance and combine it with improved power, torque and appearance. While mildly modified, this R34 looked great.

at 18psi he managed to make 467hp but he doesnt talk about any cam and cam gear tuning etc etc. just a standard RB26, nothing else. Add bolt-on power adder and he could easily break the 500hp marks.

Okay I'm seriously done here. do your own research, I did 3 years ago, and I'm 100% happy that I went with gt-ss instead of -5 or -7

We're just all very astounded that's all mate. Like Piggaz asked, do you have any examples to load up? Even some video of your own car in action?

Either way, even if hks gtss can make 380 odd kw, a bigger turbo would make that much eaiser and less stress on the internals.

Though do you have hks gtss or -9s. Even though most say its the same dam tubo, There is a comp sheet thats shows otherwise. but thats not the real point here

Edited by sydking

Hoping to have mine at about 25 psi,

Though if its not making much extra power past 20 then theres no real point pushing them in my books

So where are you at with your ride these days Sydking? From memory you were in my boat with too much lag? I've ended up sorting out my actuators and am just waiting to get my diff's sorted and possibly get an EBC of sorts

Did he tune it?

Yes i tuned it. Theres a few bits of info that have not been told with the setup. 2 main factors are built motor and higher comp.

Also all my dyno runs are done in 4th gear. Piggaz had the same question about the end speed with my GTR. I have alot of mechanical sympathy so i dont like to rev the engine to redline on the dyno. Most runs stop around 7000is maybe 7500.

CobrAA said 18psi

If he said 28 psi than I would believe him....maybe

But for now I still maintain mostus dynos (mustang excepted)

Over inflate by approx 100hp to what we see here

Generating 1.3kg/cm2 of boost and producing 467ps

That's 340kw... which is nowhere NEAR 600hp. PS is also measured at the motor.

So 340kw, minus drivetrain losses... It's under 300rwkw (at the wheels).

Do you know how to convert?

I'm just trying to help out the folk considering buying the GT-SS and all I get is whining and '' your a liar'' i don't believe you''

you will never see me rollin on your drag strip.

You don't have your own drag strip?

Doesn't matter where the drag strip is, you'll never run more than 124mph - and if you do run 128-130mph, i'll gladly eat my words that you can make 380rwkw @ 18psi on pump gas.

End of the day a turbo can only flow, what it's compressor wheel will allow in terms of airflow. Simply put, at 18psi you cannot make 380rwkw on pump gas. The turbo's are not flowing enough air to do so on a 2.6ltr motor. It's simple fact mate regardless of what you have printed on a piece of paper.

Ah, I assumed you went to 8000 RPM man. Maybe I missed that bit.

Never assume anything haha

Seems like people in here wanna make 20psi @ 3000rpm and make 350kw at wheels LOL

Not me lol gees...I'm hoping to run around 18 pounds for now and make around 280-300kw. I made about 270kw with my N1s so am hoping to improve on that a bit.

Which reminds me, I should throw them up on here for sale :D

Hoping to have mine at about 25 psi,

The bloke who owned my built engine before me was running GT-SS's and he reckons it made 355rwkw at something 26-28 pound (can't remember the exact figure). Tuned and built by Creatd in Vic, so dunno if their dyno is happy but it was impressive

    • Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?
    • Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened. 
    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers 
    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
