Did anyone go? Anyone watch it?

I just got back from spending a couple of days up there and it was awesome.....

Gotta love the yobbos on the top of the hill..... pitty no women took them up on their "magic Carpet Ride" which consisted of a piece of carpet with a hole in it :P

The weather is ever changing.... sunny bottom, freezing top.... some good grid girls to look at and the new pits are awesome.....

I think ive set a new record... Cracked open a burbon and coke at 5AM.... was sitting with my mate in about -10 degrees in our good position on the main straight and it had to be done..... trust me at 5am the place was reasonably packed.....

Pitty about the result.. i was looking forward to seeing lowndsie up the top... it was a feat in itself getting that car to finish with missing front windscreen, rear windscreen and drivers window......(sports tonight to find out why)...

Sorry about the lack of layout in my post..... ive just got home after driving since 5 and had maybe 2hrs sleep last night.....

The bogans were blowing up stuff all night which shook cars and set off alarms in the surrounding streets :)

The "heated exchange" between Ambrose and Murphy was interesting....

I was half hoping that Murph would deck Ambrose when they had their little standoff after their incident. It would have served Ambrose right as he is the most arrogant piece of work going around in the series...can't say I felt sorry to see his car on the back of a tow truck either :)

Was a fairly good race overall, but I couldn't believe the amount of incidents that happened during the first half of the race. You would have thought it was a sprint race they way some of the drivers were acting.

Good to see the red car back at the front where it belongs :P

pff red car :P dont get me started.......

Everyone was yelling for them to deck each other it was awesome.....

This was a ford year..... i saw so many FPV cars on the way there, parked and way back and saw maybe 2 hsv's.. weird huh.....

Channel 10 missed both lowndes incidents... you would think that with so many cameras they would have captured it all.

How unlucky was lowndes and how luck was not to be hurt.... can be pretty nasty when a wheel goes through your window

Yea I was down there :D I had a seat just on the end of the main straight...looking up Mountain straight....was there at 4am....loads of people there too!

Great race...Good to see Skaife back on top

But damn! No bloody sleep....I was camped the back of a Volvo XC70 next to some bloody piromaniacs from Blacktown....Didnt sleep at all :P

But overall....top few days :blink:

The "heated exchange" between Ambrose and Murphy was interesting....

it's a pity about Jim Richards and James Courtney... I was looking forward to seeing how Courtney would go.. he's a top driver

Top driver or not, I don't think Courtney will be getting a start in another AUS enduro any time soon - there's no excuse for fcking it up by trying to hard that early on in a 6 hour race. Plus he deprived us of the chance to see Jimmy on the track!

I would have liked to see Lowndes win (yep, I'm a secret Ford Fan from way back). The first mistake was his fault, but the tyre through the windscreen was the worst bit of bad luck I've seen since Jimmy's visit from Skippy last Bathurst!

Also nice to see Ambrose come unstuck - I used to be a fan but his arrogance this year has been astounding! Murphy's not much further up that food chain, so I guess it couldn't have happened to two more deserving blokes!

damn you must have been 30m away from me...... i was camped in the skyline.. passenger side... watching pimp my ride trying to get to sleep with the bombs going off..... :)

Damn...didnt see ur skyline down there...shoulda come over and said hello :blink:

    • Nah. For something like boost control I wouldn't start my design with PID. I'd go with something that originates in the fuzzy logic world and use an emergency function or similar concept. PID can and does work, but at its fundamental level it is not suited to quick action. I'd be reasonably sure that the Profecs et al all transitioned to a fuzzy algorithm back in the 90s. Keep in mind also that where and when I have previously talked about using a Profec, I'm usually talking about only doing an open loop system anyway. All this talk of PID and other algorithms only comes into play when you're talking closed loop boost control, and in the context of what the OP needs and wants, we're probably actually in the realm of open loop anyway. Closed loop boost control has always bothered me, because if you sense the process value (ie the boost measurement that you want to control) in the plenum (after the throttle), then boost control to achieve a target is only desirable at WOT. When you are not WOT, you do not want the the boost to be as high as it can be (ie 100% of target). That's why you do not have the throttle at WO. You're attempting to not go as fast as you can. If the process variable is measured upstream of the throttle (ie in an RB26 plenum, or the cold side pipework in others) then yeah, sure, run the boost controller closed loop to hit a target boost there, and then the throttle does what it is supposed to do. Just for utter clarity.... an old Profec B Spec II (or whatever it is called, and I've got one, and I never look at it, so I can't remember!) and similar might have a MAP sensor, and it might show you the actual boost in the plenum (when the MAP sensor is connected to the plenum) but it does not use that value to decide what it is doing to control the boost, except to control the gating effect (where it stops holding the gate closed on the boost ramp). It's not closed loop at all. Once the gate is released, it's just the solenoid flailing away at whatever duty cycle was configured when it was set up. I'm sure that there are many people who do not understand the above points and wonder wtf is going on.  
    • This has clearly gone off on quite a tangent but the suggestion was "go standalone because you probably aren't going to stop at just exhaust + a mild tune and manual boost controller", not "buy a standalone purely for a boost controller". If the scope does in fact stop creeping at an EBC then sure, buy an EVC7 or Profec or whatever else people like to run and stop there. And I have yet to see any kind of aftermarket boost control that is more complicated than a PID controller with some accounting for edge cases. Control system theory is an incredibly vast field yet somehow we always end up back at some variant of a PID controller, maybe with some work done to linearize things. I have done quite a lot, but I don't care to indulge in those pissing matches, hence posting primary sources. I deal with people quite frequently that scream and shout about how their opinion matters more because they've shipped more x or y, it doesn't change the reality of the data they're trying to disagree with. Arguing that the source material is wrong is an entirely separate point and while my experience obviously doesn't matter here I've rarely seen factory service manuals be incorrect about something. It's not some random poorly documented internal software tool that is constantly being patched to barely work. It's also not that hard to just read the Japanese and double check translations either. Especially in automotive parts most of it is loanwords anyways.
    • If you are keeping the current calipers you need to keep the current disc as the spacing of the caliper determines the disc diameter. Have you trial fitted the GTS brakes fit on a GTSt hub or is this forward planning? There could be differences in caliper mount spacing, backing plate and even hub shape that could cause an issue.
    • Hi there I have a r33 gts with 4 stud small brakes, I'm going to convert to 5 stud but keep the small brakes, what size rotor would I need?
    • First up, I wouldn't use PID straight up for boost control. There's also other control techniques that can be implemented. And as I said, and you keep missing the point. It's not the ONE thing, it's the wrapping it up together with everything else in the one system that starts to unravel the problem. It's why there are people who can work in a certain field as a generalist, IE a IT person, and then there are specialists. IE, an SQL database specialist. Sure the IT person can build and run a database, and it'll work, however theyll likely never be as good as a specialist.   So, as said, it's not as simple as you're thinking. And yes, there's a limit to the number of everything's in MCUs, and they run out far to freaking fast when you're designing a complex system, which means you have to make compromises. Add to that, you'll have a limited team working on it, so fixing / tweaking some features means some features are a higher priority than others. Add to that, someone might fix a problem around a certain unrelated feature, and that change due to other complexities in the system design, can now cause a new, unforseen bug in something else.   The whole thing is, as said, sometimes split systems can work as good, and if not better. Plus when there's no need to spend $4k on an all in one solution, to meet the needs of a $200 system, maybe don't just spout off things others have said / you've read. There's a lot of misinformation on the internet, including in translated service manuals, and data sheets. Going and doing, so that you know, is better than stating something you read. Stating something that has been read, is about as useful as an engineering graduate, as all they know is what they've read. And trust me, nearly every engineering graduate is useless in the real world. And add to that, if you don't know this stuff, and just have an opinion, maybe accept what people with experience are telling you as information, and don't keep reciting the exact same thing over and over in response.
