My latest dyno run:
post-22311-0-42261500-1447717241_thumb.jpg

After adding in an addition 6 degrees of timing up top and about 4 in between 3900rpm and 5400 rpm the motor refused to make any more power. Ended up making 327kW but I was leaning too much on the timing so scaled it back and she made 325kW E61

If anyone is interested in the logs, I'll e-mail them to you.. can't seem to attach CSV files.

And here's a short video of 3x cars I tuned that morning (including touching up my own, ignore the AFR readout on the S15 as it runs blast pipes)

Hey Stao, how is the new version of the SS2 different, and how much time/cost would it take to upgrade mine to the new spec (If possible)?

I'm hoping I can keep the turbine housing as mine is modded for the external gate, if its too much of a hassle I'm more then happy with the way it performs now, more just curious about details on upgrading

Thanks :)

is that petrol AFR or E85 setting ?

E61, wasn't planning to put it on the dyno but I had some hire time left so pumped the 98 tank with E85

Some updates. This is from our High flowed 21U R33 turbocharger. It is currently a prototype.

It is currently fitted to my R34GTT, car made 287rwkws @ 20psi, full boost in 3500RPM. P98 fuel.

How do you expect this latest high flow prototype to compare (in total power and response) to a HKS GTRS turbo?

The GT3071 version? probably similar

On paper this is about the same as an SS1PU. stock manifolds, internally gated. P98 fuel

I love the response of the GTRS ~ With my setup I have 5 lb at 2000 rpm and full boost at 3k.

But I realise the technology is getting a little old now. I'm wondering if there is a billet wheel turbo that has the same response but will give more power through the rev range.

Car got tuned - Tuner wasn't very happy with the IWG/Actuator so I'll PM Stao about this later. Tuner said he can get a wastegate performance graph for me to send over.

With that said I'm very happy with the turbo and the power, comes on well holds you back in the seat drives great.

I reckon drop the cat and re run the car, there's probably some restriction in the system.

When I modded my cat back and introduced a resonator and a mid muffler (both straight through) I noticed a slight drop in response. Even on the dyno it a few weeks back I noticed a slight drop in response coming onto boost, even though I loaded it up at 3k rpm before starting the run.

Going to redo the turbo back when I redo the turbo setup.

that car is running return flow cooler. He actually made within 1kw of my result when I did return flow evaluations. Drop exhaust and PWR cooler it should be sitting around 330rwkws mark.

Thanks all (Stao included) It goes for a retune early next year for e85 so I'll get it looked at then. What are the options for a more free flow exhaust? Would decat see some gains? Does anyone know how PWR compares to Plazmaman?

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
