 Expert Posts: 4458    Location: Jelling, Denmark | A picture of the results from the spring training-like event from where the pictures above is taken. I think they are pretty good compared to the other cars there.  Edited by DotMatrix 17/4/2013 11:06 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | an other race "succesfully" completed. The route was 1.6km and was a very fast route which was great until someone spilled all their engine oil up the route which was then covered by dirt by some officials which made for exciting braking and turns and kind of took the top off everyones speed. I spend the route inspection and both training sessions fixing my car. it started fine and drove up on the trailer, drove fine down the trailer and into the place where we should park when not driving. then when we were to go out the car would not start due to the key not turning on the ignition to the coil etc. so I went about routing a wire from the battery to the coil which worked, then all of a suddon the pump couldn't deliver petrol to the carbs, so I continued to fix that. when finally both things were fixed my engine bay looked like a mess, but the car drove nicely as always  but I had missed all my three non counting drives so now only had three that counted but never seen the route before as it was a brand new route. anyway it was a great day and a great route, cant wait till next outing  anyway. here are a few pictures. the rest of the pictures can be seen here: http://www.skjulestedet.dk/bilogmc/2013nordjylland/Gallery1.html      | ||

 Elf eating dog breeder Posts: 10531   Location: Guildford | Absolutely love your car. Can I have my roll-cage back now  One question, how are your carbs setup? They look like HIF38's due to the 4 bolt flange but cant work out how your throttle linkage works as normally they run with the cable to the middle of the two carbs?! Also the fact that the stock MG twin su mani is for HS2's with a 2 bolt flange not 4 bolt : Really want twins on my metro and short of running midget HS2's im stuck! | ||

Expert Posts: 4458 Location: Jelling, Denmark | FreddieS - 13/5/2013 6:51 PM Absolutely love your car. Can I have my roll-cage back now One question, how are your carbs setup? They look like HIF38's due to the 4 bolt flange but cant work out how your throttle linkage works as normally they run with the cable to the middle of the two carbs?! Also the fact that the stock MG twin su mani is for HS2's with a 2 bolt flange not 4 bolt : Really want twins on my metro and short of running midget HS2's im stuck! thanks, I also quite like it no you cant have the roll cage back but at some point in the future I will be changing it to a fia approved light weight one, but wont be the next couple of years. my carbs is two normal HIF44 carbs (one off this same car (austin) and second off a rusty mg I bought for spares, so not 100% identical, but close enough normally dual HIF's consist of a left and a right carb, but these are two normal ones linked by a shortened linkage from a xj6 4.2 with dual HIF38's. the butterfly valve-axle thing sticks out on both sides of the carbs so I used them to link the carbs. see this image http://www.skjulestedet.dk/bilogmc/metropower/08082009/100_2584_resized.JPG from page three in the journal. here you can see the linkage. I didn't bother to link the chokes as it was more difficult, only connected one up as it isn't particular lean when cold anyway. the inlet manifold is an old mini item. I cant remember the cast number but I believe its a special tuning item meant for HS4/HS6 carbs. I had it on a shelf together with a lot of dual carb mini stuff. It was 1,5" internal diameter which I bored out to 1.75" when I did the carb set. edit: just want to add that dual HIFF's on a manifold like mine will not clear the stock brake servo which is part of the reason why I run dual servos. should I make something like this again I would fit a single DCOE 45 or 48 weber and keep the stock servo. much much easier than what I did Edited by DotMatrix 13/5/2013 7:30 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | removed the ignition lock and made a switch box to place next to my cut-off switch. This way I wont have ignition problems again. sorry for the crap pictures. tried out a new mini camera thing    | ||

Expert Posts: 4458 Location: Jelling, Denmark | Last race I did a few quick fixes to finish my race, so today I moved the petrol pump back underneath the car, changed a bad battery terminal that kept needing cleaning from oxidation, filled various fluids and mounted my new start button box next to my circuit breaker. I think the car is ready now, so I still have next weekend to make a few improvements if I can think of any   Edited by DotMatrix 28/7/2013 10:00 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | took the cylinder head off in order to find out if a higher compression could be achieved through planing which I found it could not. any more planing and the valves will hit the pistons more than they all ready do.    | ||

Expert Posts: 4458 Location: Jelling, Denmark | so I started to take the engine apart to have the block bored and 4 new pistons put in and I found that it was a god idea to take the engine apart now because the cam followers were very badly worn and pitted and there was a broken piston ring. new followers were ordered along with other things like gaskets etc. and the block is now cleaned and ready to be dropped of at the place where it is going to be bored. sorry about the bad pictures, I only had my phone with me and it takes very crappy pictures. when I put it back together I will try to remember my camera.       | ||

Expert Posts: 4458 Location: Jelling, Denmark | picked the block up from boring. they had also honed the conrod big-end holes because they had become to big and the big-end bearings was moving inside them. the lovely new pistons was fitted to the conrods with new crosspins. cleaned and painted the block fitted crank, cam, followers and oil relief valve. during next week a set of new big end bearings should arrive so next weekend I should be able to finish assembling it.      | ||

Expert Posts: 4458 Location: Jelling, Denmark | R100_vvc - 6/4/2014 11:27 PM excellent work! could you tell me what size wheels/off set you are running, yours seem to sit just right in the arches Thames wheels are normal 6x13" mini superlights with 175/50-13 tyres. Front flanges had the centre lugs machined off. Rear Drums are Cooper s with 1" spacer. All arches, front inner wings and front lower arch catched the tyre so have been Cut or bens back | ||

Expert Posts: 4458 Location: Jelling, Denmark | finished making the combustion chambers bigger in the cylinderhad the other day and did a lot of work on the engine today. The engine is now assembled and ready to go in the car. I changed the axle in the rockers and some of the rocker bushes as they were spinning in the rockers arms. painted the cam-chain cover and back plate.             | ||

Expert Posts: 4458 Location: Jelling, Denmark | so here's a few pictures from this years first race in the metro. it was very nice to be out again and the new engine is running very nicely!  needing rust work soon, I know   technical inspection before the race:  people showing interest and asking questions:     Edited by DotMatrix 21/4/2014 11:09 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | I were out racing again last saturday and here are a few pictures. it went really well and I came 2 in my group and in the top third of the 62 participants that day which I am really pleased with as it wasn't without technical difficulties and as it was a very fast route. I burned 3 spark plugs which is really bad news for my new engine build but I have booked a time at a rolling road later this month to get the engine adjusted correctly and it will also be nice to know what the new power output is so I am really hoping not to find any damamged pistons or anything when I remove the cylinder-head to check very soon. hopefully with an adjustment I will be able to keep up the pace of the guy in my group who were faster than me driving a mini clubman      | ||

Expert Posts: 4458 Location: Jelling, Denmark | thanks today I removed the cylinder head to check if everything was ok after burning af few sparkplugs. every thing looks fine but I allready see som vertical marks so I will get my father to look at those to check if it is a sign of a problem.   | ||

Expert Posts: 4458 Location: Jelling, Denmark | and today the cylinder-head went back onto the car and the valves were adjusted etc. by the way, those 6 bolts that hold the inlet and exhaust on to the cylinder-head are by far the most annoying thing to assemble or disassemble on a metro engine looking forward to my rolling road session tuesday   | ||

Expert Posts: 4458 Location: Jelling, Denmark | I'm back after a very good day of rolling roading at a very knowledgeable guys garage. the engine was tuned in nicely and ended up producing more than I expected. the measurement before fitting new pistons, raising the compression and working a bit on the combustion chambers was 90bhp and 96nm (there is a pic in this journal earlier) and now it has 107bhp and 117nm. which is great the dizzy had 24 degrees of mechanical advance and was advancing all the way up past 5000rpm and the rolling road guy wanted to limit that to 17 degrees so that it didn't drop to close to 0 degrees when at low revs so we welded a bit on the inside of the dizzy and adjusted it to hit the correct spot up high, this way I have both nice midrange ignition and high end ignition instead of having to choose   | ||
