  1. .......fought, a Navajo always won; a 100% result, way better that today's lawyers when it doesn't matter how much you pay, one of them always loses. It has to be said that the Japanese Navajo-based Codes kept the Koreans out of the market for decades, so clearly a smart marjketing move. It was only when the Japanese learned to communicate in speech, that ..................
  2. I guess you could switch the phone to video and attach it to an email if the online form won't take it. The point is the world has moved on - it's 40 years since the mid 1980's and its not going back.
  3. We thought of that for the 500 and 800 tonne dump trucks, but the physics are different with applications like log trucks and urban work.
  4. We already need 20 speed splitter transmissions plus range boxes in some trucks and that's with a diesel engine set for intermittant power demand.
  5. because the can speak the edocb ut because they contributed so much to confusing the Japanese that after the war when they made friends with us and hung around the pubs picking up the code they branded the first cars with ..........
  6. For those in Victoria, take a look at the process used by an authorised Roadworthy Authority. Not only is every roadworthy checks and assessed against the standard but it gets a photo to show there is no bias. GA works to a higher standard, so its good to see RA is easier to work with. GA is also financially responsible for "mistakes" if someone is injured or killed, so they have to ensure that you are doing PRECISELY what you are supposed to be doing. Aside from the crossover of liability over the past 40 years, we've had the crossover of computers where much of the frustration you're talking about is probably occurring, particularly the repetitive work. By that should be automated. In one case I've seen a reduction of one week, plus involving an engineer plus a draftsman to do the same job with small variants over and over again. Today I do them in under 15 minutes and can save or print all the calculations.
  7. .....ceiling. Turbo has always wondered about Victorian Primary School teachers, but never said anything and Cappy's story has got him thinking if he's been doing things wrong, or .......

  9. See above. There were no emission standards in the 1950's After the collapse of the electric car market in the 1920s due to lack of range, GM was the first to introduce an EV, the EV1.

  12. Promotional; It was the 1950s; TV was feeding information about "Jets" and Americans couldn't get enough of how clever they were. The cars got "Jet Fins" and walked out the doors. People wanted Jet cars - one even had a modified steering panel and airctaft instruments. That Show truck was probably three parts wood/paper/clay, but clearly successful because both Ford and GM started developing gas turbine Tractors. Over the road trucks are close to cruise power applications, so it was a good bed and the engineers desperately tried to find a way of generating fast intermittant power, or covering the requirement with huge torque, but gave up. Here's a photo of the working GM version. You're being a little harsh on the GM financial story. GM was based on the 2 cents off a part equalling and extra million dollars net profit, and were one of the most successful companies in the world, but the US Government thought they were too rich and did a reverse Walmart on them, taking away their Frigidaire refrigerator division. That killed a complete factory in Dandenong Victoria and the area never recovered. They took their GM 2stroke diesel engine business , their Allison Transmission business etc. and GM was headed downhill.
  13. If I we're into nit picking terms, the POH for the Piper Cherokee Warrior II lists several type of pumps in its system; no boost pump but 45 mentions of "electric" pump. Many of these were explanations of how you could diagnose issues, so a POH is well well worth reading. The name itself is not the issue; I was using it to get people's minds off it doing a "BOOST" job in this category where it is used as a backup system for the failures you describe. What the OP and several others were taking about was a boost pump to boost pressure. Rotax and Jabiru engines have been developed for the upper end of the RA class doing much the same job as the entry level GA. However what to OP is talking about is boosting pressure and reading a flow gauge and drawing conclusions. Brendan has just given a good example with his XAir or what can be fitted to RA airctaft, where the basic engine had a hand operation redundancy pump, and it's been fitted with an electric pump. These pumps are supposed to fill the supply line then stop when the basic conventional carb float valve closes. In this class of aircraft, which can have all sorts of engines including Harley Davidsons, and with conventional car carburettors with a float bowl and float valve, it can be a a long process to adjust the shut-off leverage to get that valve closed against the pressure of the electric fuel pump. Thats a PRESSURE problem. In terms of saving money by not using too much "boost" FLOW in the cruise on the above system at cruise is controlled by the main jet(s). You don't flirt with reducing jet size because you're only a whisker away from combustion chamber failure of valve heads, broken pistons and seizures, so no savings here. What's more likely is Brendan's experience, the electric pump hasn't cut out and is pumping fuel out of the Carb overflow, hopefully into an open-bottom engine compartment. When you turn the pump off the fuel "burn" per hour get's better. Since, if you know fuel burn at cruise for your engine at a decimal point per hour (not per Nm), you will immediately diagnose a fuel puymp cut off problem. If you have been practising the basics of electric pump control you probably won't know there's a problem unless you have a closed engine compartment and there is wet fuel or stain at the bottom.
