Please do:), cant ask for better than that.

JimX, Have to completely disagree with you there. We all know the dyno's in WA that read high, and all the performance guys avoid them as we want an accurate horsepower figure. If I was after a high figure there are other dyno's I could have gone to, but I know that SST is accurate.

Or 300 but felt like it had 250 - there is a big difference either way

Steve - definitely not :P I'm one of the people who know better. I accept that my fuel system is leaning out at its current setup regardless of whether it's really 214rwkw or 200 or 240. The shape of my power curve is the thing I really want to fix, not the highest numbers.

When I get my PowerFC and put my 550's in I might get Unigroup to tune it, not because their dyno reads higher (I've got nfi of how high or low it reads) but because I've heard good things about their ability from other forum-goers, and their prices are reasonable. I won't care what the final figure is like, the shape of the power curve is much more important.

Who do you mean by "we all"? Everyone in this forum, or everyone you know? Workshops that have "higher" dyno readings will often make a judgement call based on their customer base. If they get a lot of n00bers in, they may as well jack it up to get more customers in. Why else would they inflate their figures other than to try convincing people that they are a better workshop?

You or I may know better, but we are probably in the minority. People in general are stupid.

JimX, even Rev210, who generally doesnt like dyno power claims, agrees that rob77s car is making the power he claims, same dyno and tuner as did GTSt's car - so your WA dyno figures being jacked up theory is pretty much mute in this instance.

Even tuner of the car has offered to let the dyno dynamics rep run the car on the rollers.

On a different tack, did you Rob or Paul, get a run in at the 'plex last night?

JimX, "We all" means all the SAU guys in WA, it doesn't take long to develope a rep as a dyno that reads high. We use dyno's based on the tuners competance, not on the power figure we get. I could go get 450rwhp on another dyno, but what does that prove?

If you read the whole thread then the basis of it wasn't the power figure, it's the fact that it was done on stock internals, stock injectors and stocks cams, which manages to prove a few people's theories wrong about the RB25's:D

I think you guys misunderstand me. I'm not implying that the dyno GTS-t VSPEC's car was done on reads "high". I am talking of why some workshops might jack up their figures. The question was asked "Why would they do it?" and I was answering that question, nothing more.

Emre, good call :P "don't know any better" it is then :P (although they will probably use their dyno printout to impress their "don't know any better" friends :))

JimX, I think that may apply to kids wanting to impress there friends, but most Skyline owners that I know here in Perth aren't trying to jack up there figures, cause we'd all laugh if they took it to the dyno's where they do have high readings.

INASNT, I'm not planning on running it until after PAS, and after the new diff is in. If it helps at all I did manage a 118mph pass with my RSM and g-sensor on the 360rwhp setup , and no I'm not interested in peoples opinion on how accurate this speed is.

I'm not disputing that at all, in fact I wholeheartedly agree. What are you arguing with me about exactly? :P I really don't understand (and haven't for yours and Steve's past few posts)

JimX, I wasn't disagrreing with you there, just saying that most of the dyno's we (SAU WA) tend to use in WA are the accurate ones, and we leave the high reading ones to Silvia owners who need all the help they can get:D

They are making sure everybody understands that SST dyno reads true.:P

As true as it maybe the point is that, others may be using a dyno that reads different, hence the reason the power figures may not make much sense. The shootout mode hasn't become the dominant form of quoting power figures yet.

EDIT : Infact, just a few months ago, it was frowned upon to quote power figures in shootout mode.

JimX, I interpreted the vain of this message (wrongly) to be implying that the dyno readings quoted from SST to be jacked up to accomodate 'stupid' people.

Emre, I agree, for some reason Shootout mode had a bad reputation, but when you look at it it is the more sensible option, as it also writes all the details of the correction factors used, so it makes it hard, although not impossible to cheat. It looks like the tide is starting to turn though, with most people asking there cars to be run in Shootout mode here in WA.

JimX :grouphug:

Although I'm trying to minimise the number of runs I'm doing at that power level with the stock internals, due to obvious reasons, I will if we can set it up get DD to run the car to verify it's accuracy.

Nah if I was going to do that I would have done it much earlier in the piece. I didn't think it was that because GTS-t VSPEC seemed pretty confident that the dyno was accurate enough to not have such a wide margin of error. And I know he's not "stupid" so until proven otherwise I am choosing to take his word for it :P

      WA PITS: Am I screwed?

      By Butters · Posted

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      By Degzy · Posted

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
