Good trolling Harry. This is what Autosport had to say: The FIA Court of Appeal's hearing of Red Bull's attempt to overturn Daniel Ricciardo's disqualification from the Australian Grand Prix was a test case for Formula 1's new fuel-efficiency regulations. By rejecting it, the court ensures the viability of the fuel-flow sensor to police both the 100kg/h maximum fuel flow and the 100kg-per-race fuel allowance. As the FIA's legal representative, Jonathan Taylor argued, competition cannot be allowed to become the "wild west". That does not mean Red Bull's appeal was frivolous. While the media is not privy to the written testimony and data, based on yesterday's six-hour hearing in Paris, there are grounds to believe Red Bull did not exceed the fuel-flow limit. It was crucial to Red Bull's case to be able to prove this with certainty. This was difficult given data gathered from the fuel rail on which the injectors are mounted still needs to be run through software to calculate the flow rate. You can understand why Red Bull wanted to rely on its own, likely more accurate data. This was not a case of cheating, because it was done in plain sight. But it was a clear challenge to the policing of the regulations. These ultrasonic sensors are new technology. While measuring flow in stable conditions is relatively straightforward, to do so instantaneously in a moving car under demanding conditions is not. The FIA has established a calibration protocol and the error bars are big enough to ensure that only clear cases of going over the fuel-flow limit as measured by the meters are punished. In the long-term, the technology does need to improve to be as precise as is required for F1. All teams have encountered problems and there are discrepancies between their own data and what the sensors say. It's tempting to cast Red Bull as the bad guy in all this, trying to pull a fast one. But it had a legitimate case and the hearing cast light on the current state of this technology. No verifiable reason was given for why the fuel-flow meter it used during the race in Australia had started reading higher than before after the first three runs of free practice two. And as Red Bull's legal team pointed out, the sensor in question was in the possession of the FIA but without any subsequent testing to understand exactly why there was this difference. All of this points to more analysis and development being necessary because there are question marks about just how level this playing field is and whether race results will be distorted by the accuracy of any given sensor. For now, while the sensors are not perfect, they are necessary. It's not ideal, but self-policing is even more dangerous. This is why the verdict was probably the best one for F1

Mercedes-AMG lawyer Paul Harris told the appeal he believed Red Bull should face a stiffer punishment as their offence was worse than that of the now defunct BAR-Honda team, who in 2005 were found to have used two hidden fuel tanks inside their main fuel tank. Who are they kidding?

Pretty ordinary effort really. Why are Merc involved in it all anyway?

Just for other random people reading this: See the image above. The spring (preloaded by the variable length actuator rod) is there to hold the wastegate shut. By shortening the actuator rod you increase the load on the spring and therefore the wastegate stays shut for longer/under more pressure, all else being equal. Air under pressure to the diaphragm on the actuator works to open the wastegate. If you are running a bleed valve reducing the air to the actuator will give you more boost as there isn’t as much air flow/pressure to oppose the spring and open the wastegate. If you are running an electronic boost controller surely the last thing you want to do is reduce the amount of air supplied to the controller – simply because controlling airflow is the controllers job. The Blitz is a dual solenoid type which should easilly allow a sufficient range of airflow to work over a 22lb setup. Maybe it isnt the case for a single solenoid type and people put a restictor down stream of it but to my addled brain that is a dodgy way of fixing the problem and would surely reduce the boost controllers responsiveness? What I am guessing is happening in this case is that there isn’t enough air going through the solenoids to oppose a larger spring force - either because it has shit the biscuit or blocked with something. Hence insufficient preload can be applied to the actuators/spring to hold it shut at 22lb or insufficient air flow provided to open them up. (Choose your preferred failure mode). Hence I can only get a rather indifferent 16lb. Anyway fingers crossed a new solenoid will fix the problem.

Um dumps are shiney Tomei items (Well they were shiney once). Rest of system is 3.5 inch. Cant remember what was downstream of the dump pipes but they were round & stainless. Point is car will run to 22lb just not on the boost controller.

Well either that or there isnt enough air pressure/flow to work with them. Can you get different springs for the HKS actuators?

Has HKS actuators. I was told I needed to replace the stockers which I did. Still no more boost.

Yeah was hoping to price just the pinion & crown wheel. Glad you can hose stuff off the line. Went to a supersprint in Busselton (On the rally stage) last weekend. 5.5k plus clutch dump = humiliating fail of a motor bogging down to 2k.

Yeah seems high. Think I will have to order a new solenoid to eliminate that from the list of possibilities. Appears to be most likely.

http://www.fairtrading.nsw.gov.au/ftw/Businesses/Advertising_and_marketing/Advertising.page Is bait and switch advertising legal? Bait and switch advertising involves advertising a small number of goods at low prices to entice customers to your business. When the advertised goods quickly run out, customers are switched to higher-priced goods. It is an offence to advertise goods for sale knowing that you will be unable to supply those goods for a reasonable period. You are responsible for ensuring that there are enough supplies available to cover a sale. You still may not be able to meet the demand during a sale but you should have at least planned for it and have reasonable stock or offers available. This is not just common sense, it’s the law. What is reasonable will depend on the type of product, the context of any advertisement and your previous trading experience. The period of offer should also be made clear in the advertisement. If an offer is available for a limited period then put this in the advertisement. If stocks are genuinely limited, such as a clearance sale, say so in the advertisement. When you can’t meet the demand, you may offer to supply the advertised item to customers at a later date eg. a ‘raincheck’. This generally avoids customer dissatisfaction as well as indicating that the advertising was genuine. Alternatively, you can supply equivalent goods immediately and at the advertised price if the customer accepts.

Ah ok. Was a bit doubtful about the wisdom of finding a 20 year old diff and then trying to track it. Guessing it is drug money for a new version from Nissan? By the way did it give you a good gain? I am sick of getting hosed by Emos out of tight hairpins etc on hillclimbs and the like.

I understand the ratios in the GTS4 are shorter and suitable for putting in a GTR. However my question is what is the best way do do this. Scrounge around for a wrecked 4 (Of which I cant imagine there are many), buy new crown wheel and pinion or is there an aftermarket option or different donor vehicle? The rear GTR diff I have has a Nismo LSD in it so obviously I want that to transfer accross.

Set is 82, gain is 4. Looking at the dyno chart the response is pretty good. 82% is a lot for 16lb.

Here is an enormously technical drawing of the installed controller. Looks fine to me.

It is nothing like Ferrari in the early 2000's. Didnt hear the call to have Britney or Homo act as number 2 - they actually let them race which is something Ferrari never dared do. Plus they key equipment (ie the motor) is shared with other teams and Merc dont have the FIA in their pocket changing the rules to suit them every five minutes. Dan put together a complete weekend. Did well in quali, raced well too. Beat his team mate and given the bullshit 10 place penalty he had did well to almost put it on the podium. Very, very good signs.

Ah ok. Will have a look when I get home. Anyone know why the race wasnt on One last night?

Tools radio: "Daniel is faster than you." I went to sleep after that. It wasnt going to get any better.

Valtteri. Bit surprised by how crap the McLarens have been this year.

Well he has done well to out qualify ze German twice in three rounds and given the way he went wheel to wheel with everyone in Malaysia the signs are looking very promising indeed. Is it to early to urge RedBull to put all their resources behind Dan for the rest of the year and get his team mate to do the support act thing?

Well yes. Which is why I posed the question "how do I diagnose it".

1. I dont have one and live handy to approximately no one (Country WA). Other wise a simple replace piece by piece would be the go.2. NFI. 3. Well it is a bit of a saga. Used to work but only at 16lb because that is what I previously wanted to run. Wanted to screw the thing up now but now it turns out it wont build boost. If it is fkd then for exactly how long it has been like that is anyones guess. The thinking was it was the stock actuators that were the problem. Replacing them was supposed to fix any boost spike issues but clearly hasnt.

Not my work! It is connected now, just working on 16lb, not what I want it to be which is 20+. Is there a way to diagnose a faulty solenoid. Can I force a signal into it and check it for, I dunno, clacking noises.

It will run to 22 psi or similar (without any finessing) but I want a decent controller. On the assumption it will go to 500 I would be looking for small gains, say 30hp at most. Would not bother if it was too hard/expensive. the last thing I need is something with a Hollywood number and no midrange. Brakes and suspension. Are they important? It is only 500hp after all. But seriously it has had a huge amount of effort put into the handling and the brakes upgraded. Yeah will do. Hoping someone may have had a similar experience and be able to finger, say the solenoids as a common failure mechanism for example.

Dunno why boost cannot be dialed in. To the best of my understanding it was that the wastegates cannot be kept shut due to insufficient flow through the boost controller. Controller is a blitz dual solenoid type. What does set correctly look like on the actuators?
