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.

JimX, would you feel happy if you car had 230rwkw but only felt like it had 200?

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

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
