There was no doubt in the figures previously recieved just interested in the variation between alot of cars with similar or more extreme mods than above mentioned, although closed on arguing this, will do my own r+d for improvement :P altho well done on that figure anyway Cheers A

Will be doing some r+d on this topic at my time will post results when i ascertain where i went wrong as my torque reading should be alot higher aswell especially with the mods and turbo choice i have gone? will keep people posted on this result and for those concerned YES i will use richards dyno again as this is the only best was to compare results and limit the possibilities of errors that could be very well encounted. Col is right on one area the comparison of results is very important hence why such use of the same dyno is important as it gives you far better chance in finding what you have done right what a certain problem may be. and if you change something does it improve or not improve results.

Lastly the original tune done by richard on the same dyno was read at 208 rwks with the same tyres but after noticed the tyres were slightly flat well 14psi difference so instead of 38 both sides one was 24 one was 36 psi checked the day after results. And aparently on the same boost. Interesting? So once my injectors are in my new boost controller is in will take back for a freshup tune and get results hopefully more improvement.

From here will locate the boost guage in too different spots one before inlet of cooler run that and then do a recheck on result verses outlet of intercooler, This will eliminate the source that the cooler is or maybe the bottleneck in my mods. This will clear alot of things up. Tyre choice could be an issue so if someone wants to let me there tyres/rims for this session would be also interesting to see if this improves/or leaves result as the same. Not many possible bottlenecks i can see after this. cam choice Maybe? As i am running standard cams, yet tho this may not be an issue. TB or inlet plenum it could be but have seen these items past 300rwkws (Col) and many more on this one im not sure if that is such a restriction issue.

But once when i have further results i will be surely able to clear a few issues up here.

For those interested my torque figure was 1364 N.M at 132 kmph. For those wanting of my mods those members may clear that up on page 4 in mod thread of members section.

Thankyou

Cheers

So was my car the only car to piss out oil onto the floor :P Something that i dont understand tho, I had a max torque of 1259 Nm on my printout. But from factory is 353 N·m. Whats going on there ?

1259 Nm is at the wheels, so your diff ratio will multiply your real fly wheel NM's...

In short find out your rear diff ratio and take thr 1259nm and devide it by the diff ratio to get the fly wheel NM... Simple... :)

As i am running standard cams, yet tho this may not be an issue. TB or inlet plenum it could be but have seen these items past 300rwkws (Col) and many more on this one im not sure if that is such a restriction issue.

Hey Adam, have not be ignoring you just be super busy with photos/video and trying to answer a million questions via PM.

Ill give you all the info you need to know in the next few days, but yes in short I have stock cams and a stock inlet manifold. But a few key modifications are needed to push the extra ponnies... I will talk to you soon...

Edit... Oh forgot, its a Garret brand GT30 0.7 front cover and 0.82 rear with external wastegate. The trim is standard GT30/40 Garrett issue.

No problem col, i realise the busyness you are in at the moment, must say is this alway like this for ya after a dyno event :P lol
No fortunatlly... :)

But ideas and feedback via PM is always welcome, cant improve unless you know where to improve...

glad you can see and understand out point of view col. again hats off to the execs.

power figure wise, it doesn't matter if it's reading high or low. as long as it is consistent (which it wasn't)

i suppose people prefer dyno dynamics to other dynos, because not only does it have a higher power reading. BUT it is considered a standard i.e. autosalon, etc.

edit: what nathan said.

top stuff

What a great day...

Thanks to everyone....

i had so much fun! hey col it was 181 sif rob me of the extra 1 kw :D:wacko:

met some new people had fun with the old sif post photo of my looking so seedy....,,

once again thanks to everyone who organised and ran it.... i love Marc's sausage.. it tastes so good :huh:

Who owned that white 33 with the bomex/veilside looking kit with the nose off? That was the most incredible engine sound i've ever heard, and i'm not even into cars that much.

Seriously wow :wacko:

That would be me by the sounds of it. I love the sound of it too I cant get enough of it

I only had the bar off because there no way I would of got over that hump to get on to the dyno.

Spewing about the power figure thou. Theres something wrong somewhere. I got 330rwhp ages ago with a lot of problems and clutch was one of them. This time 90% of the problems have been fix and cams put in but I got a lower power figure but the car feels a lot faster on sure of that. Ill say the std clutch would not of helped it in anyway thats for sure,

Ill the car to gavan woods to find the problems, install the new clutch, and tune it and hopefully then ill be pushing 300rwkw's

EDIT: And it only hit 0.55 of a bar on them runs. Thats the other thing I need fixed

Oh Please explain on this lol. sounds like fun. Cheers A

One thing I learned from the day...

Remember to ensure that your bonnet is properly closed before hitting the gateway at 100km/h driving home afterwards :|

Spewing about the power figure thou.

yeah no shit, 230?kw as opposed to me expecting 330-350 ish

thats quite a variance

i had fun regardless, and the SAU crowd *always* makes the sunburn worth it

Oh Please explain on this lol. sounds like fun. Cheers A

Obviously they opened the bonnet to check before the dyno, and when I drove it out again, I never noticed they'd only just laid it back down and not shut it properly (probably shouldn't have been staring at all the far sexier skylines and paying attention ahead instead).

So I hit the ramp onto the gateway, hit 100 and just see my bonnet start wobbling like crazy (it seems that 100 is the magic number for getting it to do that, doing 60-70 all the way up sandgate road and it just sat there and didn't move).

I was just like... oh shit... the first exit wasn't for at least a couple of k's down the road, those where some "fun" k's.

I believe shootout mode was created to remove differences between dynos and conditions at different workshops on different days. Whether shootout mode reads high or low is irrelevant as it should always be consistent.

Agreed

Ill the car to gavan woods to find the problems, install the new clutch, and tune it and hopefully then ill be pushing 300rwkw's

You'll be there in no time Jarrad...

Yeah at half a bar with a slipping clutch i reckon you did well to get 230rwkw...

Cant wait to see her with a new clutch and some more boost...

You should catch up and ill have to put some cams in to reclaim bragging rights... :wacko:

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
