I want the 4 and 6 wheel version ... Would there be a problem with The type approval in Belgium?

Hi everyone, My sweet almost 14 year old daughter entered a charity project/competition on Facebook. She painted a gnome/goblin/kobold/... (there are a lot of words in the beautiful Englisch language for these little men who live in our gardens) and she posted a picture and a story on Facebook. I persuaded her to choose one of our beloved colours ... green and put the figure in Ireland, origin of the BRG. So everyone who has a BRG Seven, and also everyone else, please help her because she really needs "likes" https://www.facebook.com/#!/photo.php?fbid=520013558035169&set=o.295579320556594&type=1&theater Thanks and if she wins, everyone who passes my home this year (on the way to Spa-Francorchamps, Nürburgring, ...) will be treated on a good bottle of Belgian beer.

Hi guys, To start with Elie, it' s still for the Elise. I could not resist buying a pair of mirrors for only 50 EURO. The next Seven project is still in the negotiating process. :-) If I get my hands on that VVC Seven, I' ll put a next silly question on BlatChat, "how do I remove effectively paint from a Seven". Thanks for the sandpaper suggestion. I was afraid of damaging the carbonfiber with sandpaper and was thinking of a mild paint remover product, heat, ... I have no idea about the quality of the carbonfiber, so it' s going to be trial and error. I did a small piece with a 200 grain and the result is very good. In fact carbonfber looks much better without lacquer on it! I' ll probably go for a matt finish. Jack Flash

I got a set of seconhand carbonfiber mirrors, but with the clearcoat damaged. That' s why they were cheap. 😬 How do I remove the clearcoat in a reasonable time? Fingernails are effective, but ... Ideas to prepare the carbonfiber in order to put new laquer on them are also welcome. Jack Flash Edited by - JACK FLASH on 13 May 2013 11:06:40

I know, these alloys do not fit on a Seven, but nevertheless ... This is a set in pristine condition and perfect for some-one wishing to have a spare set for his or her 340R since these are long out of production. These fit also on an Elise Mk1 but the mounting of longer studs is advisable. The location is Belgium but transport to the UK or another country in the neighbourhood can be arranged. Make a sensible offer and we' ll discuss an "all inclusive price". j.jackflash@hotmail.com

Hi again Kenny, I also might be interested in the badge, just nice to have, if it is an original badge and not a reproduction. It looks indeed almost mint on the pictures. But perhaps it is impossible to be absolutely sure ... Jack Flash

Kenny, I would like to continue the questions/discussion on the theme of the cam cover. I'v got a Caterham Twin Cam 1979 and I always thought it had the wrong cam cover. I got it with a sixties cover, with LOTUS written on both the left and right side. BTW, in the beautiful typical LOTUS font and black crackle paint. Also with the three eared oil filler cap. Which type of cam cover did you find on your Elan? In the mean time, I changed the cover to the last type with LOTUS BIG VALVE on the front above the chain and adapted to a dry sump system. Jack Flash

Guys, A lot of usefull and wise advice. in the mean time, I had the toe in adjusted and I must say that the values Elie stated are much better. As for the bump steer, this weekend I'll start playing with the tyre pressure and soften the dampers. Technical upgrades are for the next stage. Today I have passed the Belgian MOT and apart from some fidddling at the carbs to get below 4.5 % CO, everything worked out. At the first test I had 5.0 % and afterwards I managed 1.6 % with idle at 750 rpm and a lot of backfire. An interesting remark was that there was a significant difference in the left and right dampers at the front. I know the front is always critical, I never have problems at the rear. To be continued after the tests in the weekend ... Jack Flash

Great ideas and valuable information. Everybody can imagine my difficulties. So I' ll start with the easy things: 1. Set the toe in at 0°20" +/- 0°10", thanks Elie (walking encyclopedia) 2. Soften rear dampers, I stiffened them last year and they stand about halfway 3. Consider rose joints at the back, I heard about it but is there advice on suppliers. I have no problems with the front, it is neutral and has a sharp response. I know that there are ways of improving the front but to my opinion that is not really the priority. The only thing is perhaps changing dampers and springs. Is there some-one with practical experience of other makes of dampers and spring rates for a LA. Another variable is wheel / tyre combination and tyre pressure. I use the standard 185/70 with pressure between 1.6 bar and 1.8 bar. I believe that is about 22 psi and 26 psi. Is there any benefit in going to lower tyre pressures for road use? Jack Flash j.jackflash@hotmail.com

Doug, I know your problem because I have been thinking for 5 years to find a decent and neat alternative for the plastic washer tank. Reason for it being lack of space since I did some improvements on the brake piping and put the battery on the position of the heater. For the time being, I use a classic Lucas bottle with a separate pump. This however is still too big for me, the best solution is a small aluminium bottle but unable to find. Jack Flash

The first 6 years of Twin Cam ownership I spent most of the time working on the car, doing test runs and getting it 100 % reliable. Finally I am starting to "use it" and I have come up with following questions. 1. The settings at the front have always been "straight ahead". What is the experience with toe in or toe out for road use. Values for settings? 2. The rear axle has the annoying habit of surprising me with serious bump steer at unwanted moments. Ideas for improvement? This is an absolutely standard Super Seven Twin Cam with the absolute standard LA suspension. A set of new Spax shocks and new springs were mounted a couple of years ago. No intend for trackdays or racing, this is a strictly road use classic Seven! Jack Flash j.jackflash@hotmail.com

Hi again everyone, Finally I found the time to take the plugs out and I also discovered NGK BPE6's. Since I want the Twin Cam to have optimal performance in its standard specification, I am going to try the NKG BPE7's. They are not that expensive, so why not trying to see if there is a difference. I checked some websites and found following NGK plugs "7" Twin Cam engines: NGK B7ES : short tip, fast road NGK BP7ES : fast road NGK BPR7ES : resistor? NGK BP7EVX : fast road platinium NGK BR7EIX : iridium (replaces B7EVX), short tip? Who knows the difference and who has experience with these types? Jack Flash j.jackflash@hotmail.com

Hi, Great to compare, I was planning to take off the valve cover in the next couple of weeks. I' ll let you know what I find. The cams I have were checked by Burton and they confirmed that these were the right ones for a tall block for road use. Jack Flash j.jackflash@hotmail.com

Hi everyone, Very interesting thread but also confusing about which type of NGK plugs are the best for a Twin Cam. Is there perhaps a difference between the "normal" TC in an Elan and the tall block in our Sevens. The NGK website gives the NGK BP7ES or the NGK BPR 7EIX (iridium). Has some-one got experience with this new iridium type? Elie, the lotus Ypres tour on the 2th is impossible for me. This due to a massive workload and several commitments for the daughters. I am happy to have a one hour blat each weekend, just to keep the Twin Cam running. Jack Flash j.jackflash@hotmail.com

Hi again. Just by accident I saw pics of your Twin Cam on the internet. The chassis plate is very interesting. You have chassis number CS3 3844 TCRS and I have CS3 3851 TCLS. So there is only a difference of 7 cars between them and both have the RS2000 Mk2 rear axle. There us even a possibility that they have been together in the old Caterham site up the hill during the building. A great opportunity to compare these Sevens and exchange information.
