  1. 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.


  2. I just did a drive from Amsterdam to Friedrichshafen via the 61 from Venlo to Karlsruhe, what used to be unlimited speed.

    Now the 61 is only unrestricted from Venlo to Monchengladbach which is a small stretch. All the rest is now 100 -> 130km/h.

    Any idea's for a better Netherlands to Switzerland routes?

    P.S. good general topic, this should be sticky.


  3. If you read the interview with David Hunt, he clearly states that Tony Fernandes approached him to get the Lotus name back into F1, and Hunt said to him to give Group Lotus the chance first, which they took. He may have planned to buy the rights to "Team Lotus" later, but not a year later, only the circumstances with GL causing him too.

    This I don't understand,

    - Why would Mr. Hunt say please try it with Group Lotus first, thereby reducing the value of the Team Lotus brand to zero.

    If that is really his statement, he allows to have a second Lotus name in F1. So the current claim of F1Malaysia to not allow Group Lotus in F1 is not legal.

    - If the "Team Lotus" name of Mr. Hunt is so valuable as it is claimed now, why din't F1Malaysia continue to push for the licence of Mr. Hunt, and ignore/or get the the Lotus Racing name afterwards. Did Tony really expect when acquiring the license from Group Lotus that he could use the real Lotus brand (Logo)?


  4. I cannot see that "Team Lotus" name / IP rights giving exclusivity on the Lotus name in F1, or Hunt would have been starting litigation in 2010 as owner of "team Lotus" rights at that time.
    .

    Why didn't Mr. Hunt protest to using the Lotus name in F1 last year. Or did he had a contract with MalaysiaF1 from the start, and was that the trigger fot Group Lotus to stop them?

    What is REALLY clever though, is that in 2009 it was seen by enthusiasts as a bad idea for Litespeed to dig up the Team Lotus name and use it on a new British F1 team. After a stormy one year relationship with Group Lotus, we are happy for a Malaysian businessman to use it for a malaysian flag carrying team - Fernandes media management is awesome IMHO

    Mr Fernandez was extremely lucky that Mr. Bahar appeared to the podium who did al sorts of things to make himself very unpopular (Changing Lotus into a marketing oriented company) thus having being given the situation that Lotus was not anymore the nice lovable sportscar brand, but a big bully OEM, while he could play the underdog. If Mr. Bahar was a car guy, and did not do all this marketing nonsense while building the nicest lightest new cars. He would have gotten away with the F1 situation and people would accept the rebranding of Renault,


  5. The statement said 1Malaysia not only wants the fee to include the sale of the Team Lotus name, but other factors including the development of a new brand, and loss of income from merchandise and sponsorship.

    Proton confirmed that it is willing to pay only for the name."

    How can you count development of a new brand as you sell a old brand.

    also loss of income from Merchandise won't count as they are not allowed to sell Lotus merchandise,

    So that's only the name and some sponsorship, (Which sponsors for 1Malaysia are non TF related?)


  6. For the first bit of the trip.

    - Arnhem to Oberhausen, via the E35 "Oberhausen straight", for a nice full throttle ride

    - For a scenic route try the route from Mastricht, Spa to the Nuburgring, and stay on the west side of the Rhine

    Also good, hurry yourself to Marseille, "or take the route Napoleon", and follow the coastline from Marseille/Nice to Firenze.

    P.S. Good topic.


  7. I know it has the wrong flange, only as these turbo's are the latest in MHI turbocharger technology that have good match to generate up to 330hp, I think it's worth the effort to create something of a adaptor flange.

    Then I'm also investigating what we have available for a direct bolt on solution, we have a unit available with the connection dimensions as in the picture below which look rougly the same. Only this is for a up to 450hp application. And would not help transient response for lower than 370hp outputs.

    But if you have any engine data I can also assist you in finding a nice solution. Normally this requires:

    - Peak kW @ rpm

    - Peak Nm @ rpm

    And the following data at both peak kW and peak Nm

    - Pressure and temperature @ Compressor in, Compressor out, Turbine in, Turbine out.

    - Brake specific fuel consumption

    - Air and fuel flow.

  8. Me and a lot if others, because the real fans of the team don't care about the name, just like Virgin have their own fans,

    The fans that were only there for the name, have jumped ship over to Lotus Renault GP, because they think it has more to do with the old Team Lotus.

    That probably makes you fairly unique.

    I think most people admire a team for it's unique caracteristics, McLaren being the super clean technical perfectionists.

    Ferrari the team about passion. Sauber the team next door swiss underdog. Even Red Bull has a identity of their own,

    as the thrill seeking danger sports brand. Only I'm struggeling with the identity of F1Malaysia. Did they think they can

    buy a identity of the brand of technical innovations and seeking the edge of the regulations.


  9. Last year Lotus paid nothing and got lots of publicity from having a Lotus F1 team..

    Other way around, last year F1Malaysia paid nothing for a brand that gave them instant credibility and access to sponsors.

    Sure Lotus got some free publicity. That was the agreement on which both parties would be happy, but it never

    was the intention for Lotus to give F1Malaysia the ownership of the brand.

    For F1Malaysia the Lotus brand is absolutely necessary to make a good business in F1.

    While for Lotus it's nice but not vital to be in F1.


  10. I find that hard to believe, especially at a time Mr Bahar was in charge.

    First there was the naming deal with Proton and F1Malaysia to use the Lotus Racing name,

    Then Dany was installed as the CEO of Lotus, and was not so happy to see the naming deal

    with F1Malaysia. At that time he certainly was interested in the Licence of Mr. Hunt but did not buy it.

    Only when F1Malaysia made a breach of contact by using the Lotus logo (And maybe some other stuff)

    F1Malaysia bought the license of Mr. Hunt. I can't think Mr. Bahar just forgot about that option for F1Malaysia.

    It can be that Mr. Hunt tried to sell the license to Lotus earlier in time, an naturally Lotus was not interested

    as they could not afford to be in F1 anyway.


  11. I'm still really amazed that people regard the team of Tony F the real succesor of Team Lotus,

    He only bought a name. Which may or may not be legal to use in F1.

    It's like Spyker, nobody thinks that the new Spyker is the resurected Spyker brand or factory.

    It's seen as a total new brand. Which uses styling influences of the past.

    Same as the team of Tony F, they are a F1 team which is using the name and some

    styling cues from a team from the past.

    Both Tony and Danny are business people handeling only for their own good.

    The people in the company's make who they are and carry on the culture and legacy of a brand.

    The legacy and culture of Lotus is there in Hethel. Not in Sepang, nor in Hingham. and maybe, not yet or ever in Enstone.
