  1. Thanks for sharing, will watch all of them for sure Attached links to two old articles from the vehicle dynamics magazine. The first one is more positve, the second one a bit less, so the balance is right :-) Enjoy !

  2. interesting subject attached link to an article with some details on engine additives http://www.skepdic.com/slick50.html more links at the bottom of the page Cheers marc
  3. Hi Thread on G-car fuel filter with a few cross references May be helpful Cheers Marc
  4. Many thanks for organizing this excellent event ! really enjoyed it. Cheers Marc
  5. Hello Marco Find attached a picture of the fuel pressure regulator (85 turbo). Connection underneath goes back to the right fuel tank Cheers marc
  6. Hi I will be coming from Frankfurt Hahn with Ryanair, but only on the 18th. Can't make it earlier. Plane should arrive at 6.50am on London Stansted airport. Have reserved a rental car and will come to Hethel asap. If anybody wants a lift, let me know. Cheers Marc
  7. Simon Have balanced mine a while ago and the effect was pretty significant. Engine was running smoother afterwards . I posted a few pics on how to balance the carburettors with a MAP sensor on the forum back then. Cheers marc
  8. Hi Wayne Think you don't have to bring it up to date, imho the S3 is really nice and timeless in its original form. like the title "purists beware" :-) Cheers marc
  9. Steve I actually did some tests with closed throttle. All I can say is that readings were significantly lower (80-100) , and not at all repeatable. There's nothing wrong with an enquiring mind :-) Cheers marc
  10. Hi Here are my compression readings cold vs 1/2 hot (+/- 45 deg) cyl. cold (PSI) at 45 deg (PSI) 1 120 122 2 118 120 3 116 120 4 115 120 measured with Motometer compression tester range: 250 PSI (http://www.samstagsales.com/mercedes/mm6230011101.jpg) Open throttle is essential to get a proper reading. Cheers marc
  11. on an turbo esprit you can change the filter without "cutting" holes. you'll have to remove the underbody for better access though. as the fuel filter is a part that "is meant" to be replaced I would be astonished if you had to cut holes in the bodywork to do that. Would assume that Lotus has thought about that - but you never know. Cheers marc

  13. Hi Have tried to balance the carburetors on my 85 turbo Esprit recently. A carbtune II borrowed from a colleague somehow allowed me to do something, but fluctuations were pretty significant. I wasn't really confident with it. This is why I tried to do something with a manifold pressure (MAP) sensor. Conclusions In combination with an analogue voltmeter this setup gives a stable reading, thus allowing a precise balancing of the individual carburetors. Having balanced the carburetors the car's response has improved significantly. Cheers Marc
  14. very sorry to see this, especially on a G-esprit same fate for my cousin's speedster - but that doesn't really help you

    Judder!

    hi I can really understand your problems - but that doesn't help Have been working my way through the ignition system recently as well. You can buy the gunson flashtest to get an approximate idea about the HT voltage, or try the setup with the two "modified" spark plugs. Guess you should be able to determine if the ignition is faulty or not that way. The pressure of the fuel will also drop if the voltage at the pump drops - maybe something to check as well. Cheers marc
