265/35/18 on the rear...granted I do have them at 40psi, so there's probably traction to be had in lowering the pressures a bit. They are only KU31 so nothing special in the grip department. Thinking of swapping them for Nitto NT05s, as Ric (HEKT1K) is running them in 235/40/18 form @ 280rwkw with no loss of traction in 2nd. If I could fit 325s I would lol.

what EBC u running? try adjusting the settings so it doesn't ramp on as hard.

did that with mine and it only breaks very little traction so the power is very usable in the dry.

running same sized tyres but with achilles ART sport.

Good to hear your result Birds. I still need to post my updated dyno result.

Its funny how before there weren't results for the ss1pu, I posted mine and everyone is acting like there is something majorly wrong with the car when it initially made 242kw..

Meanwhile now we have:

Birds 252kw

Kasko 250kw

Myself 251kw

And that now appears to be accepted as normal. Gotta love forum e-mechanics :)

On another note, I took my car to Wakefield park on Sunday...I think I may have had a bad batch of fuel since it was pinging on the freeway during the drive down however I put in a new batch of fuel then 'tested'' it after which it didnt ping at all so decided to take it to the track. Only did 4 sessions and was taking it easy since I didnt want to risk the car but the turbo is pretty nice on the track. Good power to use out of corners, more top end would be nice but whereas the car felt super underpowered on the track with the stock turbo, it now feels... i wouldnt say fast, but normal.

The turbo is torquey enough to lay long black lines out of corners in 3rd gear if you wish, nice to see them getting longer and longer in the rear view :)

Nice to see they are on par.

How much boost are you running on the track?

Dude i think you need better tyres if you're painting in 3rd :P

Haha nah I run one of the grippiest street tyres you can get, with my power I can usually get full traction even in first on a good surface... Federal 595 RSR.

You just wait till till they overheat a little on the track then flick it sideways and paint all you like ;)

Nice to see they are on par.

How much boost are you running on the track?

I run full boost, 251rwkw around 17psi. Did you go to the SAU track day on Saturday?

I think there should be more improvements to be made on Bird's car, I've seen it before as it had lot of stock egr and epa legal stuff on and the cooler isn't great either. Other thing is the ss1PU tested on mine was running on ebay side mount exhaust manifold.

Not sure if that did help making the extra power. its available for ss1pu people whom's interested to find out at samll cost.

Nah I was getting the things ready for the tune.

Really keen on getting out on the track just don't know how the stock engine will hold pumping 20psi through it for the day.

Might invest in a few more things first such as oil cooler and better radiator as I am still running stock

Not to split hairs, but I did produce a rather restricted 258...it would have run fine on this, but we altered parameters purely for engine longevity. This isn't too far off Stao's own test figure and I'm confident there is more I could do to push the number higher. But yes, an increase in sample size does add to the consensus of what you can expect with a given turbo and your average setup. I think we've established that, if you plan to just whack an SS1PU on your car and not do absolutely everything Stao has done, then you can expect results closer to ours than his. Therefore there's no more deception here, the results speak for themselves and the only way that you could fairly say Stao's results are misleading, is if someone did exactly what he did with his car (right down to rebuilding the engine, using the same tuner and same dyno) and came up short.

As a side note, I think some of you guys get way too caught up in the dyno queen figures. When I dropped my car off at Race Pace, I said to Chris...I don't care about the top end, this is a street car. Shoot for what we can get, but in the end I'll take a drivable tune over bragging rights. And these days you're not winning any pissing contests bragging about having anything >300rwkw, so what's the point? If you want something useful to gauge the peformance of a turbo, either hit the track or the quartermile like siks has done and let those numbers do the talking...because these are the numbers that matter. Dynos are first and foremost tuning tools. This turbo moves me through the traffic, it burns rubber when I want it to (and sometimes when I don't), I have no regrets about any of my purchases :)

PowerFC boost control kit. It's basically an HKS EVC without the fancy screen. Adjusting so it doesn't ramp on hard may fix my traction issues, but I think it is also the nature of the turbo...it comes on quite early and when it does, boost climbs real fast. If I can just find a way to foster it (e.g. more grip), then that should translate to a faster car than trying to tame it (playing with boost etc.).

  • Like 1

The bit that puzzles me is that a year ago everyone was saying " we want a turbo that looks stock and produces a responsive 250kws"..now stao has busted his nut building exactly that and there seems to be a bunch of people complaining its not making enough power when it's making exactly what was asked for..

And to those who keep saying " oh but stao made....power"

He has probably spent more just on tuning than we have on our cars

Stop trying to squeeze blood out of a snail people...

lol well yeah that's it isn't it, look how far we've come from the turbo upgrades of yesteryear. A few years ago they would have killed for responsive high flows that put out the numbers we're seeing. Now with HG and Kando you've got some cheaper and, dare I say it, better alternatives to the old "get a GCG highflow" or "get a Garrett 3071/3076" solutions for chasing power.

I think it will be very interesting to see what, if anything, Stao can do to improve the Kando turbos.

Ok so you three are running an atr43 ss1pu or similar hybrid turbo. I'm running an atr43 ss1. How does the pu change the turbo?

Edit. What boost control are each of you running, I need to get one but undecided what one.

agreed, if he pulls off the sl2-20 int gate, it will be a hot product!

From memory anything with PU indicates a larger hotside. So its probably got a bigger rear housing and possibly a larger rear wheel.

Stao can clarify.

Yes from memory the PU is a bored out rear housing with a larger rear wheel. Your result looks about right if yours is the non-PU model. Despite ~25kw less, it looks a bit more responsive than mine or Kasko's.

WTF is with all you nuffers using electronic boost controllers having MORE boost drop than myself using nothing?

On internally gated turbos EBC's don't do much, it's more about the actuator. When I had my old internally gated HG, I never even used mine, just switched it off. Can mess around with the gain setting and all that, but the turbo worked well off the spring so I didn't bother.

Externally gated, different story.

EBC do help abit. because it can cut out all pressure on the cold side to the actuator which MBC don't. still need a strong actuator to eliminate boost drop thou, but I'm working at a different direction at moment.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
