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?

    • There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)
    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
