Why do petrol cars have vacuum pumps?

Discussion in 'General Motoring' started by -, Aug 1, 2004.

  1. Heh heh - R-R engineers were tearing their hair out trying to find out why
    Packard manufactured versions of their V-12 couldn't make the required
    power output. Came down to poor tolerances.

    Yours must be the Hollywood version...

  2. Typical Merkin response to being proved wrong.
    So by this little tale I take it no US engineering ever goes wrong?

    Wonder why you buy so many imports, then? And Packard still make the
    finest cars in the world...

    Packard has come on greatly since merging with Bell and starting to make
    computer equipment instead of cars.

    Typical arrogant British know-nothing prick. I worked with a bunch like you
    back in the '70's in Saudi Arabia. The L-1011's we worked on had the Rolls
    Royce RB211-524B engines, made especially for the Saudis. Hot rod engine.
    All they did was increase the thrust rating a few thousand pounds and up the
    turbine max. temp. limit with virtually no design changes. Time after time,
    they'd scatter compressor bearings, shred turbine sections, and generally go
    to pieces. You Brits had every excuse in the world for it, except the right
    one. You built a shit engine and wouldn't reengineer it. I was reading the
    local Saudi Gazette amongst a bunch of types like you one morning. There
    was an artcle about how Rolls Royce had gotten a contract to provide energy
    generation to the city where we all lived. I said,"You assholes better
    stock up on flashlight batteries." Funny thing, we had very little trouble
    with our Pratt and Whitney engined aircraft. Don't, by God, tell me about
    British engineering.

    In the years since I've seen a couple instances of GE and P&W make some
    mistakes, but they sure tried to rectify them no matter what the cost.
    Never saw that happen with Rolls Royce. Their tech. reps blamed every
    operating circumstance and environmental condition they could drum up, but
    refused to point the finger in the_right_direction. Britsh arrogance and
    shitty engineering.

    And the sun has most assuredly set on your empire, tough guy.

  6. My - you have got a chip on your shoulder. Wouldn't they let you play with
    their planes?
    It's never risen on yours, wimp.

    Of course, this is a car group, and we could talk about the shitty US
    products they export here. Right at the bottom of all reliability and
    satisfaction surveys.

    There's precious little engineering in the US anymore, sadly. It's all
    bean counters.

    Packard's demise was due to their ill-advised acquisition of Studebaker
    in 1955, not to any engineering shortcomings (and secondarily, to their
    decision to go a little downmarket with their vehicles.) The only
    engineering shortcoming that I'm aware of is the weak oil pumps in the
    55-56 V-8 engines, which no doubt would have been corrected had they
    stayed in production longer than two years. But for the most part, a
    Packard is a thing of beauty, both aesthetically (OK, except for the
    "bathtubs") and mechanically - you may not know this, but Packard was
    the only "small" auto mfgr. to produce its own, from-scratch automatic
    transmission (by "small," I mean "not GM.") Hell of a transmission too
    - had a lockup torque converter and everything. Got one in my 56J and
    it is great when it works right (age has taken its toll on the seals,
    every time I let it sit a couple months, I have to dump in about 5
    quarts of ATF to get it to work again...)

    Why would it take any longer than a power brake car with the same size
    rotors and pads? Je ne comprends pas.

    Funnily, the *worst* electrical parts I've ever had on any UK made car
    were distributors by Delco.

    And this from the nation that birthed Lucas Electrics. The firm that
    invented darkness. They also made the fuel control amp. for the
    aforementioned boat anchors on the L-1011 and were totally unreliable like
    the engines. Also the grievous toad of an autopilot on the Fokker F-28.
    You know, I wouldn't have what you call a "chip on my shoulder" if the Brits
    I worked with every day could have at least admitted to such sorry design
    and reliability problems. The Boeing and Lockheed tech. reps had to eat
    crow at times when we'd draw their attention to deficiencies and they'd make
    an honest effort to sort it out. It wasn't just me, it pissed off the
    Germans, French and the other American workers there. But you're right,
    this is a car group and I'm off topic. I remember how it was, and is, and
    it got on my fighting side. We'll just have to agree to disagree.

  11. Oh, do let's; it'll be jolly good fun, old bean. We can start by
    discussing how the Jeep Grand Cherokee beat out your homegrown Range
    Rovah for best 4x4...IN YOUR OWN UK MARKET!

    And when we've finished chatting about that, we can make a comparative
    list of profitable, volume-exporting US and British automakers. You know,
    a friendly game of pick-up-sticks to see which country has the more
    successful, more robust auto industry? That'd be splendid.

    And once that game's won, we can talk about Lucas electrics -- the
    justified laughingstock of the entire automotive world -- and maybe have a
    couple laughs over SU and Zenith carburettors. That'd provide a nice segue
    for talking about how the UK's pathetic attempt at an auto industry
    managed to keep modern emission regulations out of the British question
    clear up until *1991*, due to a claimed inability to meet such tough
    standards.

    H'm...naw, better not talk about that last one; it could lead back to a
    discussion of Lucas electrics and SU and Zenith carburettors.

    Tell us, ol' chap, what British car do *you* drive?

    [/QUOTE]

    Odd, that. Delcos are some of the best distributors around, it's the
    Prestolites that are notorious junk. What era are we talking here? The
    "window" distributor had a run of over 10 years and it's a good unit.
    Or are we talking the newer HEI stuff?

  13. Homegrown? Bought by Ford from BMW? Are you mad, or just living in the
    past? The concept of the Range Rover as a reasonably comfortable go
    anywhere vehicle at a sensible price died years ago. It's now just the
    same as any other expensive bloated lifestyle 4x4.

    But I'd still like your reference for that.
    As in Chrysler being taken over by M-B? And all your other majors loosing
    money hand over fist? Having to buy 'foreign' makes to try and stay
    competitive? And you wonder why you're in a recession?
    You bought that too...

    Strange you should worry about the reliability of car electrics given the
    number of electrical fires you have in your homes through inadequate
    wiring standards?
    So you want your emission standards imposed on the rest of the world
    whether needed or not while you're the biggest waster of oil resources?
    That's logic?
    Perhaps you'd name the makers of your much more reliable electrics and
    carburettors when Lucas was the major supplier in the UK? Of course, I've
    not got much experience of US made cars - they were never exported to the
    UK in any quantity. You don't need to be told why, I'm sure. The couple I
    did have dealings with had headlights so poor as to be dangerous.

    Some makers here did use US electrics. Delco distributors. Now they *were*
    a bad joke. Delco batteries are common too. They don't last either.

    Almost all the American auto makers used vaccum wipers at some point.
    They were very common up until 1958 with Ford still using them on the
    Brono up until 1968. Vacuum wipers slowed to a crawl under heavy
    accleleration but they worked wonderfully at idle :)

    Are there any "British" cars extant? Didn't Ford, GM and -horrors- the
    Germans buy up everything?

  19. However, I do have a great deal of experience of older UK cars fitted with
    Lucas equipment, and have found it no more unreliable than any other make.
    Perhaps most electrical problems on old cars are caused by grounding
    problems, and Lucas haven't any control over those.

    Being such an expert on UK cars fitted with Lucas products, you'd give
    some actual examples of poorly designed or manufactured parts?

    And your opinion of a mass maker who did better at the time?
     
    Dave Plowman (News), Aug 10, 2004

  20. The only mass maker left is Rover who produce a range of now getting
    pretty out of date cars.

    The 75, which was designed during BMW's ownership, is rather a good car
    of its type, especially in diesel form.

    However, I'd hardly say the US car industry is in fine form - would you?
