I had a idea Why not using 2 dc motors. One being a dynamo the other one powering a high speed fan. The good thing about the dc motor is that the speed of rotation varies according to the voltage it is powered by. SO the principile is easy and puting into practice can't be two difficult and the efficiency should be around 65 to 70 %. I have plenty of 120w dc motor so i just need to make a bracket find a high speed gearbox for the second motor. He Voila. You have a electric supercharger. I will give you some news! Jack

I have a tacho with a mind of it's own! The needle varies from 0 to 6000rpm in a blink of an eye and it's not me pressing the accelerator. I would like to know if someone had a similar problem and which part i need to change. Which is the most likely to be damage? the tacho or the sender unit? Jack

Cheers For the Offer Craig What about Sunday? Can you remind me where you are based? Jack

Hello I need to replace my rear tyres, I have now the michelin Pilot 16 x 45 front and back I would like to know what consequences on the handling if i fit some 50 or 55 at the back and keep the 45 at the front? Jack

Cheers Guys I call the guys in Alyesbury to see what they can do Jack

It's leaking from one bolt which i don't no the function! I've manage to reduce the leak by a minimun but the smell of pretrol is very high Jack

Hi Any one in Chesham or nearby I could borrow a 20ltr or more petrol can? I have a leak in my fuel tank and of course it's the leak is 3/4 down. I'm going to repair the leak with " Leak Fix" from plastic bond. Will this be a quick fix or will it hold? Any other ideas how i can do it? jACK

Hi Hoopy I would be interested. The solenoid is loose but not dead yet! Drop me a mail me you have you magnetron repaired Jack

Hello I'm looking for a starter motor for my VVC powered 21 or just the solenoid. The current one is a Magneti Marreli Thank for your help Jack

Hi Pete Are you talking about an FPR? If yes i need one as well so if we order two it might be cheaper for both of us Jack

Cheers Bare Does this mean that the idea of a fan inside a air filter is not a good idea? Jack

I have some oil leaking out of oil cap from my dry sump. I believe it the cork gasket which needs to be changed. Any ideas where i could get one? I'm looking as well for a solenoide for my starter motor. Can't find any thing on the web please help me Jack

Last winter i had a very good look at super charging my 21. The main advantage of the supercharger is that it doesn't produce as much heat as a turbo. Which is a very good thing in car which have heat troubles There is something on the market called an e-ram which is in fact a fan inside a K&N air filter http://www.electricsupercharger.com/ I wanted to control the speed of the fan according to the position of the throttle which will result in the quick death of the electrical motor as it in only design to work at full throttle. The other option is to go for an Eaton supercharger, or pinch the one from your neihbour's Merc 230 Kompressor. This unit will fit nicely under the bonnet of a 21 and i'm sure an SV will accomodate it. The addition of an intercooler is recomended as well. Jack

It look like i have a completely different hot start problem with my 21. My starter motor will turn but the engine will not start. When it start there is a massive missfire, which clear after a few minute. I took the heat shield off last night and discovered that the small connector to the coil was broken off. Which can explain some mal functionement but not the miss fire Anybody got a spare coil? Or any idea where i could get one? Jack

I have an old fashion speedo which i've just change the cable (las night). This morning travelling to work it was indicating a 120mph @ 4000 rev which is not possible as in fith the ratio is 25mph per 1000 rev. this is nearly a 16% error. Is there a way of recalibrating a speedo? Jack

Tiddy Can you give me the place where you bought it from! No reply from Bennetts Jack

Hi Luke I've emailed Darryl Richards and this is his answer:

Looked into it! And it will be done! Jack

Thank you very much Luke I've been looking on rthe web for it and so far i have been fairly unlucky. Could you pointme in the right direction to find them? Jack

Halfords do a good one for around £60. If you are leaving in windy place my 21 use to be underneath every night. Jack

Sorry, I don't know the cost. Best is to talk to Clive. Regarding ground clearance you have to be careful on speed bumps and that's it. Jack

Hi Martin Who's 21 is it? And where are you? We are, 21 owner, a nice bunch of people. As your friend to register to our mailing list http://mailman.se7ens.net/mailman/listinfo/21s I am sure we will be able to help him Jack

Thank very much for your answer The way i would like to go it's to have a fully mapable ECU but it is not ready...Yet Luke I will have my head done and have the exhaust cam fitted by DVA power latter on this year. I would be very interested in which Weber adjustable FPR you are using. Jack

I'm sure a lot of you have the 52mm TB of the MGF fitted on thier engines Well, i had it as well! And I reverted to the 48mm! When i was running the 52mm, i had a lot of hesitation, didn't notice any hike in performance but did notice in a hike in the petrol comsumption which isn't cool. I wonder if i am the only one who did experienced this problem. My car is a 21 and the engine was fitted in 1996 Jack
