Wow, impressive results Warlord... I've gone for super response with my GT-RS, by using a small diameter tuned length exhaust manifold and external gate, and your setup is not a great deal laggier than mine. I obviously make more power low in the rev range, but we make the exact same power at 120 kph and then you run away from me with an extra 80 kw at the top end.

my gt-rs was fun too but this spools real good once i corrected the boost controller from the way it was set up.

It is hard to tell spool from that with no rpm axis, but looks like a nice wide power band impressive power for the boost. Driven it yet? How does it go?

yer driven it ,its different to my old set up its not violent with the same power very different to have so much traction but it will break out once we turn it up,need to go back and get this tune sorted out a bit more tomorrow as its feels and smells a bit fat

Boost looks real stable, what boost control you use?

its a greddy profec b 2 with a tail wastgate.

ok so its 16 ish psi at 343kw on 98 petrol

injectors are 850cc sard

i now need a bigger fuel pump

that graphs a bit hard to read,it starts of at about 4200rpm ( 110k's)

looks very similar to my gtx3076 i must say.. bit laggier initially but stronger after the midrange

Bare with me on this, I could be off but it nonetheless sticks out to me that if 110kph = 4200rpm then it looks like it is hitting 16psi at around 4300-4400rpm. That is miles off full boost at 3400rpm, and puts it more in typical GT3582R territory - which to be fair is more like what I would have expected.

Have I missed something here? I am used to Dynapacks where they can do a proper rpm vs power curve and it's a bit easier to scrutinize this kind of thing.

ill be going back today as there is a few problems !!!!!!!!,the boost controller was set different as i mentioned earlier and boost was building slower than it should of, easy fix and feels much better. ill get the afr dyno print and power to rpm,boost starts at about 2400 500 and a video put up,i could rave on about some things that im not happy about but ill see if they can be sorted out first.

A friend of mine had his GTR tuned by DART at one stage and reckons the tune was also quite fat but he preferred the on road outcome to any other.

The same GTR has been tuned by a few different shops chasing the right outcome. To my understanding the DART tune was the best even though it ran fat.

dart is a great tuner and always has clean a/f ration lines and good power,but this time i went to my local pulse racing.any way all is good car is going back to be cleaned up on wed and hope for a better result with the same fuel set up for now.

o and as for engine builds you can not beat jim.nick at dart first engine build 45,000 km and thrashed with two different turbo set ups and when it was pulled down it was perfect inside.i thought id chuck that in.

i am hoping that this tune after round two will be the best ive ever had ill be sure to let you guys now.

also i would not spend to much time looking at the dyno for answers yet wait till its done properly.

Oh sorry I always get DART and Pulse confused LOL!

I was aiming to give some reassurance in the rich side of things with a DART tune, but it turns out that was irrelevant lol. I have also had mates tune at pulse with nothing but positive feedback too, so I'm sure it will turn out great.

Very strong power curve nick, looks like Mt Everest

That line is not far from running vertical lol

Firstly Nick, thoroughly enjoyed reading this thread, I applaud you for sharing your build,

Secondly, that power curve looks more like a 16 year olds pimply face!!!

A bit surprised paul left it like that

Hopefully you have better luck the second time around.

round 2

first dyno is what happens when the vct is turned on compared to be for when it was not !!

the second is when the fuel pump looses voltage and the fuel pressure drops & when you tune with a vac leak/boost leak from the hose that went from plenum to Bov were it poped off to charcoal canister it must of popped of sometime on the dyno and not picked up.result once hose is put back on bad idle/stalling at times and possibly leaning out now.

voltage problem now fixed with pump wired to battery with a relay and thicker wire.

round 3 on this F$$$EN Tune

      I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly.

      find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank.
