Standard 1G-GTE Dyno.

[SoarerTT]

hey dude here is my dyno chart although my is a single high mount conversion. this was donr by the previous owner when it had a t25g on it. runnnig 14psi i think. it had stock intercooler and a 3 inch with high flowed cat exhaust.

Ie if it pings in the heat it won't gently pull out a half degree of timing it will rip out a massive chunk of it to save your engine.

While I understand what you're saying, it technically wouldn't be hard to mimic the way the factory does it, as is, the Adaptronic has some controls over the severity of the retardation, and the duration. What I was more thinking of though is regards to the ignition trims. No, you dont want it trimming when it doesn't need to be, but if you spend the time on the correction maps, there is no reason it couldn't be the ideal result for each temperature. Problem being, that takes ages, and people don't want to pay for ages That would be the reason I come to for most tuners not setting them up.

Hope thats clearer dude, its always so easy to take things the wrong way in text

No wuckas mate, thats why i'm trying to throw in as many smileys as possible

[JustCallMeOrlando]

I just thought I'd throw this out here, because I didn't quite realise exactly how different the curves were until I plotted it out using Excel.

The original graph was from the last dyno day I went to where it made ~164rwkw, with the boost controller set to 17psi. What it was making psi -wise at peak power I have no idea because XSpeed never got back to me with the graph. Twas also with a suspected BHG. The second is from the Adaptronic now it's tuned. AFR's were abysmal with the factory ECU, and a perfect 12:1 ruler line now it's tuned. The new run peaked at 167.5rwkw and boost is set to ~17-18psi, once again i'm not sure what boost it made at peak power (Rod if you could be a total champ here and possibly grab the graph with the boost curve, I think it's XX81WA.027, I don't have it handy).

Linearity and consistency wise, the tuned setup owns. It's nice having that consistent top end. That said, it'd be even better if I had the matching mid-range. As I said in my thread, I'm officially confused

[1jzracing]

this is all very interesting, depressing and encouraging all in one!

i have just dynoed mine and we got 173.5kw on 16psi and thats with a single manifold, gt2530 frame turbo and ecu!

i was thinking it should be a little more but i still have standard intercooler with 2" pipes and 2.5" tail pipe (3" head pipe) so they may hold it back slightly... maybe the turbo is running out of huff too, it holds good steady boost

it comes on very strong and early with broad power curve so its good to drive, cant see how people are getting similar power with the twins

1jzracing
What ECU are you using?

[1jzracing]

1jzracing
What ECU are you using?

wolf 3d v4,

its running multi coils waste spark and boost controll

[SIKTOY]

What's the driveability like on the road
And price of the ECU

[1jzracing]

ive had the ecu for ages, it was running the bm engine

drivability is awsome it feels like its got more power than it actually does because it has such big torque, max power is reached at only 5700 and holds right through to over 7000

we were a tad late on the throttle with the power run, it actually made over 100rwkw at only 4000rpm when we were tuning it

[SIKTOY]

You will find that the intercooler is the main restriction of your power,
When I tuned mine it could have made more power but the cooler wasn't efficent enough

Are you using standard injectors or 7m ones

[1jzracing]

yea i think the exhaust housing is a little on the small side too

im using 7mgte injectors, the std injectors were just hitting 100%

[YelloRolla]

The 2" inlet pipe is unlikely to be holding the power down to 173kw. My car has made over 190rwkw on a couple of different dynos with 2" piping (50mm from turbo to cooler and 60mm from ic to t/b).
Who tunes your Wolf? I am asking as matter of interest, and nothing to approve or discredit your tuner. I also happen to run a Wolf - but mine is the ver 3.1. My car is tuned by Alex Blackson at Redline Rotary - he is a Wolf nut.

[1jzracing]

i know alex he has helped me on many ocasions, he is a top bloke

i do most of the tuning with the help of a mate on his dyno just up the road, hes not so familiar with wolf so he just runs the dyno and i tune, makes for a quick result

in reality a tune only needs to be as good as having the right mixtures and timing after that there is no "hiden horsepower" to "magicly unlock" ...its all down to pure physics

it is still only a t25 frame turbo with a .64 exh housing and 2 inch piping all the way from turbo through standard intercooler to the inlet, plus 2.5" tailpipe so if you add all that up its probably not too bad,

like i say it makes 170rwkw at only 5500rpm so the torque is huge, feels pretty fast

will take it to the strip over next few days and see what it runs

[YelloRolla]

I realise this - I was asking out of interest.

I also agree that it's not too bad - I think that it is even good. I have the HKS GT2540 on my car too.

[1jzracing]

so how do you find that turbo? whats your setup and power

have no comparisons to pass any judgement, again feels fast especially in a little beemer

i think its the same turbo, its badged 2540, i picked it up second hand so cant be sure of anything, it has the housings to suit a GTR skyline, which is a pain in the arse as they have a unique rear flange, must have been an unbelievable LAG monster with 2 of them on an rb26

[YelloRolla]

Mine is one of a pair from a Skyline too. I got the correct flange from Liverpool Exhaust (which was good because it saved me from making one).

My car makes 190rwkw - at around 6000rpm - power is over 170 from about 4500 to 7000.
I use 32mm primary tubes - so a little smaller than yours, and I use a 50mm throttle body.
The T/B is set to change with an improved intake manifold that I have designed.

edit/ should clarify that I run 22psi and I use an external gate with 3" exhaust.
