    Surprisingly, I apparently got one of the first '55 Studebakers that
    used the plastic-insulated wire rather than the cloth-covered wire that
    was used previously. It was still intact and flexible when I pulled the
    harness for repairs 5-6 years ago which made me happy as I was not
    looking forward to laying out for a new one.

    N54, but same principle.
    I've not found it to be that unreliable (touch wood.) There *are* a lot
    of electronics to fail, and that scares me a little, but that's true of
    every modern car with a few notable exceptions worth having and none of
    mine have failed yet (good lord I hope I don't regret posting that.) So
    far I've paid for fluid changes, aforementioned OFH gasket, and a bunch
    of random upgrades (euro light switch, spare tire kit, winter wheels and
    tires, alarm, sat tuner, etc.) Despite the reputation for being hard to
    work on I was able to install the alarm and sat tuner in an afternoon in
    the driveway following excellent directions easily available online, and
    without any unusual tools that a moderately DIY-oriented enthusiast is
    unlikely to have. Really, no harder than changing a car stereo in any
    garden-variety car. The biggest challenge to DIY work is actually
    lifting the car to get underneath due to the very limited ground
    clearance, but that goes with the territory of pretty much any decent
    handling car, and if it doesn't, an enthusiast is likely to change that :)
    Neither the Miata nor the Elise has a back seat or a usable trunk.

    I think having a 3er for a daily and a Miata or Elise for weekend fun
    would be a great combination. My mom actually has a Miata for a "fun
    car" and loves it (as do I) but I don't have the space/funds to justify
    another vehicle purchase.

    And where is all this BMW advertising? I must not pay attention to the
    same media that you do, BMW seems to really not advertise at all
    compared to other manufactureres; people buy them because of
    reputation/previous experience/glowing reviews in magazines and on
    enthusiast-oriented TV programming.

    what cognative dissonance trip are you on this morning? you catalog a
    bunch of completely unacceptable failures one day, then here you are the
    next saying it's not unreliable! are you not taking your meds?

    dude, what is wrong with you this morning????

    can we change who shows up with meaningless drivel on r.a.t?

    ah, got it - you idea of a car that "handles" is an extended cab pickup.
    got it.

    you sure won't have funds if you're driving a bmw.

    nate, i'm sure that if you're nice to your mom, she'll let you out of
    the basement occasionally. you can have the tv on while she hoses you
    down and changes your depends.

    What failures have I catalogued? I had a leaking oil filter housing
    gasket at the time the car was purchased, which was repaired and the car
    has been trouble free since. That is the ONLY issue that I've had in
    this car in about 6K miles/several months since purchase (car has 77K
    give or take.) There have been NO other repairs to this car under my care!

    <rest snipped because clearly there's reading comprehension issues here.>

  5. No shit!

    The BMW E46 M3 was the first normally aspirated production vehicle to
    make 100HP/Liter. PERIOD.

    Don't mind JB. He just likes to rant on about how his choices are the
    right ones and can't admit that anyone other than his short list of
    approved manufacturers can make a decent car.

    I'm trying to think if there are any reasonably mass-produced automotive
    engines that achieve 100 hp/l - I'm pretty sure Honda S2000 qualifies as
    well, FWIW. Not sure if there are any others. I'm not counting Wankels
    as similar to a 2-stroke comparing displacement isn't exactly fair as
    they have more power strokes/displace more air per revolution than an
    Otto or 4-stroke Diesel cycle engine.

    At the end of the day, though, hp/l is not really what matters - it's
    hp/weight, and also BSFC if you are racing in a series with limitations
    on fuel use...

    the e46 was released in 2000 wasn't it? the honda prelude SiR had
    100hp/l in 1996 if i understand the dates correctly. the s2000 was
    released in 2000 [though its tokyo motor show debut was in 1995].

    you forgot to add the important qualifier - "in comparison with a buick".
    irrelevant drivel.

    true enough. how's that 3200 lb behemoth working out for you?

    irrelevant drivel.

    I didn't forget anything.
    http://en.wikipedia.org/wiki/Honda_Prelude


    Type S

    One version of the fifth generation Prelude, a high-performance model
    called the Type S, was only available in Japan. It was equipped with the
    2.2 L H22A, featuring VTEC and producing 217 hp (162 kW; 220 PS) at
    7,200 rpm and 163 lbf·ft (221 N·m) at 6,500 rpm.

    Close, but not quite. Still respectable though.
    Quite relevant.

    It's much easier to achieve a certain hp/l number with a two stroke than
    a four stroke. Do you understand why? Same effect in operation here.
    It's great. It rides and handles acceptably well, and unlike a CRX,
    Lotus, or Miata, I can actually carry three passengers and some luggage
    in comfort, which is important if you have friends.
    Really? So if you have a limited amount of fuel, BSFC is not important
    at all? Fascinating.

    oh, but you did!

    so if i understand you correctly, when you were claiming "100hp/l" you
    were trying to do so for years 2001-2006 [the years the e46 was
    produced], while somehow trying to claim that it's better than the 217hp
    / 2.157l = 100.6hp/l of the 1996 prelude, correct? so year for year
    doesn't figure in your calculations? or are you just too spectacularly
    incompetent to otherwise avoid being confronted by the facts on the
    s2000 instead? [rhetorical]

    it's a red herring and therefore irrelevant.

    wow, not only do you answer rhetorical questions [sic], you do so by way
    of suppositional nonsense!

    how old are you nate?

    red herring irrelevant drivel. see above.

    Actually I came in late to this conversation, you were discussing
    power/displacement ratio with someone else and I just jumped in because
    I found it interesting. I don't know really anything about Quaaludes
    other than that they really were supposed to be some of the nicest
    handling FWD cars made, I just hopped on wiki and tried to find which
    engine to which you may have been referring. The bit that I quoted was
    the highest hp/l ratio that I saw; 217 hp/2.2l is still not quite 100.
    Now if the actual exact displacement is less than 2.2l, then OK, you get
    that one.
    It's quite relevant, unless you're the type that likes to compare apples
    to oranges to "win" a usenet argument.

    OK, in that case: You're both wrong. The very first Mazda production
    rotary yielded 110hp from 982cc. In 1965. I "win."
    I'm just saying, your "approved list" actually includes some good cars,
    but they are not generally practical as a primary vehicle. You're
    attempting to compare sports *cars* to sports *sedans* (or coupes, as
    the case may be) and then running down the latter because of the
    comparison. Dissemble much?

    The fact that you consider it irrelevant is telling. Results matter.
    How you get there is less important.

    If you need an explanation of why my example is not actually a fair
    comparison, see here:

    http://www.drivingsports.com/site/2008/12/rotary-vs-piston-engine-equivalency/

    Likewise, a two stroke completes all its power strokes in 360 degrees of
    crank rotation as opposed to the traditional 720 of a four stroke
    engine, therefore to normalize it WRT most of the engines that we
    encounter and the traditional methods of calculating displacement, their
    actual geometrically calculated displacements need to be doubled to make
    a fair comparison.

    Alternately, instead of just using "displacement" as a raw number, we
    could use "displacement per revolution" e.g. an Otto or Diesel engine
    with a 3-liter displacement would have a 1.5 liter/rev displacement,
    which would actually make more sense, but the convention has been in
    place for so long that a change just to allow for fair comparisons with
    the exceedingly rare (only found in the current RX-8) Wankel engines and
    the similarly now rare (although somewhat common in the past, and we
    didn't appear to have confusion problems then) two stroke gasoline and
    Diesel engines.

    That all aside, with the increasing prevalence of various forms of
    supercharging, actual displacement seems to be becoming less and less
    relevant anyway...

    i didn't "get" anything - you simply shot your mouth off without any
    attempt at basic fact checking. as per usual.

    you're just grasping at truly pathetic straws.

    you're putting false words in my mouth, then not even making sense with
    what you say i said. fail to comprehend much? [rhetorical]

    you really are brain damaged. anosognosic.

  15. Nate Nagel

    Nate Nagel Guest

    Um, I *did* attempt to check your facts, and I found that it was a
    nominal 2.2 liter engine with 217hp. If you have cites to the contrary,
    I'm willing to be corrected, because, as you well know, hondas are
    something that I have little to no experience with. In fact I am trying
    to remember if I've ever even driven one. Since you're the supposed
    expert, please, enlighten us.
    No, if you consider power strokes per rev irrelevant, then the Wankel
    wins, hands down.
    Man Look! I came here for an argument.
    Mr Barnard (calmly) Oh! I'm sorry, this is abuse.
    Man Oh I see, that explains it.

    nate
     
  16. jim beam

    jim beam Guest

    then you're simply incompetent because you didn't check properly.

    i've already given you the numbers, retard! do you want me to repeat
    them??? [rhetorical]

    no. and i'm not wiping your ass for you either. retard.

    he said, grasping at pathetic irrelevant straws.

    so why do you keep coming back? [rhetorical] you are truly brain damaged.

    Nate Nagel Guest

    Hey, you're the one making the claims, you back them up.

    I'm not even saying you're wrong. I *am* saying that the burden of
    proof is on you because I (and likely many other readers of this group)
    are going to take your word for jack shit because you're hardly an
    authoritative source. And before you get your nosehairs all in an
    uproar, that's the way life works - unless you're a published expert,
    when you make a claim you need to back it up. And if you *are* a
    published expert, then the backup ought to be in your published works.

    I shouldn't have to spend more than a minute or two researching anything
    you post, you lazy satchel.
    In what way is it irrelevant? If you want to name a winner in the
    "breaking the 100 hp/l mark in a production automotive naturally
    aspirated engine" unless you exclude them and/or apply an adjustment
    factor (generally accepted as 2, e.g. the nominal 1.3l 13B engines
    should be considered to be 2.6l for purposes of this discussion,) Mazda
    wins.

    Unless you want to start looking at two-stroke motorcycle engines... do
    those count, too? I'm sure I could find examples of those putting out
    over 200 hp/l before applying an adjustment factor.
    Boredom? the need to feel better about myself? Who knows.

    Clearly most of the intelligent people have left Usenet; I guess I'm a
    little nostalgic for the good old days when we used to have actual
    intelligent, enlightening discussions. A little libertarian/egalitarian
    part of me truly believes that a moderated forum is inferior in most
    ways to an unmoderated group; however, you and others like you are
    starting to make me seriously question that belief.

    nate
     
  18. probably, although I've never seen anything from lucas here.
     
  19. nope.

    But I have had to do parking lot wiring repairs of modern german cards.
