Thats is because Stao's running lot more boost most of the time which really shows the advantage of a built motor plus the all the expansive supporting mods and he's only uses one of the top tuner in Australia.

He usually post result of a maxed out turbo, no one's crazy enough to run 24~28psi on a stock engine plus their tuners won't let. I hope he can post some results on 15~18psi based.

Most of Staos charts show him pushing around 20psi, rarely over, and getting 300ish.

17psi nets him 290kw. Check the first page. He updated it last week with his most recent results.

EDIT: That's on the G3 profile, by the way.

Havent seen any car that can match Stao's results on the same turbo so far, no matter how much everyone tries, I wonder why- they all read 10-30rwkw lower on average

Are we really complaining about ~20rwkw variance, with all the variables at hand, not the least being a completely different / seldom used dyno setup? Or that Stao's car has spent 20 x more time on the dyno, than any other car, finding ways to extract every last kw out of his turbos and his supporting mods?

The key to make more top end is making sure the boost control setup can hold boost at 7000rpms, people whoms are slightly down in power normally found them selves few psi down in boost at that point. There's a combination of method that I use including adjustment of preload on the actuator, wastegate controller and EBC. Pretty simple, normally just few mints while car's on the dyno. How ever i can not pre-set as final boost level varies between cars.

Good quality supporting mods do make a difference specially at high boost levels. I'm not concerned as those can be easily purchased.

How ever I am concert with tunner's ability and skills per discussion in page 182, without precise tune, the whole setup can not perform at its best, it is also frastrating as all the expasive research work that has been put in to the turbocharger turn meaningless

ssshhh... secersts of the dyno ;

If I give you back my turbo, and you you install it into your test car, and it makes less killerwasps than your published magic turbo, what is the prize?

I think we all understand what you're say saying Stao, it's just a very few who don't.

Refer to back to back test in page 213. The mainlane dyno read 5kws less then the current dyno I'm using and that was before engine rebuild at 300rwkws. The dyno is fair. What Turbo do you have to send in? Quite happy to do a test relating to it.

I don't own one of your turbos as yet Stao, my responce was pure hyperthetical, and sarcastic.

My point is:

All dynos are not identical,

All engineers/ mechanics have not the same skills,

All tuners have not the same skills,

...and yet I am 99.95% confident that all of your turbos will produce less than 5% difference in results than your magic [rollseyes/] turbo, given they are used with the same hardware.

like most things on the internet, people only come here to complain when it doesnt work..

but even a garret 3076r for instance, known performer..some people easily make well over 350kw with them while others struggle to crack 300kw..

Stao results are perfectly indicative of what his turbos can do..there are no tricks or gimmicks to the results just a shitload of R & D..Too many people think they can just slap this on for 1500$ and get the same result, but it doesnt always work that way..

Most of the people complaining about results aren't even HG customers though, lol. What Stao just said serves as the best clue to it all: engine rebuild. In relative terms: an engine that should be void of the power losses you can expect after 15-18 years of operation...

I don't think the foolish people are suggesting the turbo is different, but that Stao makes more power because of some secret squirrel business with his engine, i.e. it's not stock.

I agree. I think the main difference between Stao's car making ~320rwkw and others making around ~370rwhp is the fact that his tuner knows the car well and knows it has forged pistons. I know that my tuner is not comfortable running 20psi into my engine, and most tuners will setup boost controllers to bleed off boost up top not hold it to redline. Simple things like that, plus maybe give or take 5-10rwkw for differences in dynos. Very easy to see where results are differing.

I personally think that if you have been for a ride in a car with a HG turbo then you will know they are capable. Even if there is something not quite right yet in the setup, you can feel the potential is there. Hard to put into words on a forum, but I think most if not all the people who have had the luxury of being in a variety of cars with multiple setups will agree with me.

I agree. Luke's car is fun.

But a GTR is better pirate.gif

Also the AFR in previous tune is all over the places, its leaning straight up after 6200RPMs. is it pinning up top? DVS should be able to touched it up or I guess he would erase it for a completely new tune.

I agree the AFR is all over the shop - main issue the tuner is having is control of the 1000cc injectors with NISTune, bottom end is very very rich.

Top end should be fine that's actually 7000 not 6200, just too much slip in box and dyno for it to read properly, the lean out is just the back off once rev limiter is hit, doesn't ping, quite the opposite, backfire on gear change cause it's too rich.

Yes the return line into the hard piping has been angled away from the AFM - keeping in mind that that was happening with G3 and old piping kit. A new one needed to be fabricated cause the SS2 is a smaller turbo - almost an inch too short to fit to the old 4" setup.

Yeah I've already spoken to DVSJez. will get a retune from him once I get the car back, don't want to be pinging for the 80k trip from here due to being too lean (honestly though I expect it to be too rich over 3000) to Somersby, which is where he's located.

Had a big day with Kasko, made some decent results but will let him tell the story.

At the end but im very impressed with the ss1. Drives really nice, spins the tyres and sounds awesome

This is reassuring :)

Hopefully get my car back tomorrow and can tell a similar story :)

One of my favourite things about the SS1PU after installation, was the noise...very unique sounding turbo!

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
