  1. I wonder if they wouldn't be better off appealing to the entrepreneurial leaders in skateboarding/snowboarding, like Rob Dyrdek.
    I do agree on this one, but get Tony Hawk instead.

    On rap culture getting involved with "high" class brands like Dom Perignon, Lotus, Ralph Lauren etc..

    If the target audience can even afford your product. Such marketing only works for a small time frame,

    pop culture is always quick on changing brands. Like Chrystall, for a while it was nice, but the old reliable

    customer base in fancy restaurants changed to a different brand because of the rap relationship. Now they

    are left with nothing. Even without the bad publicity eventualy the rap community would have changed their favourite drink.

    I also do agree on the target marketing, I think the money in future Lotus buyers is in the Financial and IT companies.

    Better get some fancy 1 page adds in the lifestyle magazines that apeal to these people.

    Still my favourite lotus marketing tool is getting their cars in some nice computer games as one of the main event cars.

    Test drive 1 and Lotus Esprit Turbo Challenge 2, were hugely contributing to me owning a Lotus now.

    Although F1 and James Bond can also not be forgotten for that.

  2. When driving around at 110/120kph, there is a light judder in the steering wheel,

    No a constant vibration but a vibration going on and of every other second,

    I have all my wheels balanced. but this did not have any influence on it.

    Can this be due to brake disks, as this is rotational mass that is not balanced,

    or can it be due to worn steering rack or column??

  3. Hi Mike,

    Rebuilding a turbo is no problem to do yourself,

    just make sure you don't damage the compressor blades or R shape in the compressor cover.

    As explained all components are balanced separatly, although after assembly of the cartridge

    the turbine shaft and compressor assembly are balanced together in the normal production process.

    This will have only minor effect on durability and is mainly done for noize. (Which if you don't care is ok)

    Good quality parts in your neighbourhood can be found at BTN Turbo in Uxbridge

    Then when you rebuild make sure you use the correct torque value for the compressor nut.

    Also make sure you get the actuator values right, as you have a single turbo some deviation should be

    ok, but clearly mark the lenght in assembled condition.

  4. Agreed, the latest Lotus action against TF/TL seems beyond pointless, can someone explain what DB's problem is with TF's purchase of Caterham?

    What's not to understand,

    You have a car company and a logo, now somebody managed to get the license to use your logo and is buying a car company to put your logo on. And start competing you with your own brand.

    I don't think Lotus is against TF buying Caterham, as long as it stays being a Caterham, without any relation to Lotus. (Besides that its a old Lotus design) Now Tony even made

    a "Team Lotus" edition Caterham, that's almost as confusing as a "Lotus" edition Renault F1 car.

    This reminds me of saying, all the people who think Malaysia F1 is running a F1 team in true Chapman style, and Lotus not as they just bought themself into a existing company and not designing their own

    car from the ground up. What to think of TF then who bought himself into a car company, just putting purchased logo's on a purchased car company.

  5. Renault couldn't make the Team pay so sold it as a financial burden. Do you think Genii would be selling it if it was profitable??

    Honda couldn't make it work, Spyker couldn't, BMW, Jaguar, Toyota (with their huge spending power) etc etc etc.

    What makes you think that Lotus can?? I'm sorry but I just can't see it being anything but bragging rights and a burden on GL.

    I don't think Lotus is in F1 for the long run, they are only in there to counter F1Malaysia. (And maybe a bit for exposure)

    As soon as F1Malaysia will give up it's logo, Lotus can get out of it again and focus on making cars and money.

    Although Lotus would like to be in F1, they know they can't afford a team of their own. Certanly not before they have

    a Ferrari like status. Only now Lotus can't afford not to be in F1 and let F1Malaysia get away with their brand.

  6. Not even this Z?!...

    No not even the Z8, I don't understand what is special or advanced about it. For me not realy BMW,ish.

    What I do like about BMW is the level of engineering, I think they are the best by far in therms of quality

    innovation reliability. I only can't see myself driving one. Also I'm not to much of a fan of the ride feeling,

    I prefer the ride of a Mercedes, for which I'm way to young. So a nice E-class, that would also be a car

    I secretly want but can't quite see myself in.

    I stick with my Lotus,

  7. Most widely used method is the APQP method, which I think was originally developed by Ford.

    On the marketing side, thats not listed in the APQP, which is basically used only for development.

    Normally marketing comes with a plan and a direction based on marketing study and the

    level of predevelopment in their company. Or predevelopment will push one of their projects.

    When a decision is made, predevelopment will create a management vehicle for the big bosses to drive,

    based on this, a decision for the project is made, and it will enter the APQP phase. Which is not to

    different than the list you describe above.

    Mostly you have 2 or 3 design loops on rapid prototype process to make a prove of concept.

    After this the DVP will start based on soft tooled process. When the design is frozen Series process is

    launched and validated.

  8. As I have to much toe out on the steering and the U/J are already set to the maximum in, I'd tried to

    put some extra thread on the steering rack, I tried both 1/2UNF and M12x1.25. And neither of these fitted to the

    steering rack thread. Strange thing was that the M12x1.25 tap slid in the U/J very easy. And was even a bit loose.

    I cleaned everybit and no die would fit the thread.

    Anybody knows which thread size should be used?

    It might be that the U/J are non original, and forced on the steering rod ends. So a picture of the original setup might help to.

  9. Problem with VG/VNT turbochargers is not so much the controllability, but more the operating temperatures on which the VG/VNT turbine as limited. In normal automotive applications these can only be fitted to Diesel engines as the nozzle is limited by maximum temperatures of 830 steady 850 peak degC. (While typical Gasoline engines run between 930 - 980 deg). Also the nozzle system is a non oil lubricated system which in a Diesel application is slighly lubricated by the soot the Diesel exhaust generates. I expect the duarability of such a system in a gasoline application not reaching the 25 hours. The only VNT/VG turbocharger capable of handeling Gasoline temperatures is the Porsche 911 unit which is super expensive (Aircraft grade pricings)

    A better option to avoid turbolag is a more modern wategate turbocharger configuaration. With the latest compressor wheels a higher boost pressure and flow can be generated from smaller units which reduces the rotating weight (Improves trainsient response). With Mike S we are going to test a new unit for max 330hp.

    Also a option will be to go to a leightweight turbine wheel material like TiAl which only has again some tempreature restrictions and a high price. Althouh I think on the Esprit the temperature will not exeed 950degC anyway so this should be good.
