Expert Posts: 4458 Location: Jelling, Denmark | migliacars - 21/1/2016 7:57 AM Still the good old A series. 1293. Cc with a supercharger. And a 7 port head. On Jenveys tbs and dta. All built by migliacars. Car is restricted to 7800rpm and does 167 at the wheels. A bout 210 at the fly. She weighs in at 700 kg. very nice bhp. you follow the newer and bigger cars nicely. yes I can hear in the videos that you have a rev limiter which you hit some times so internally is the engine something like: steel crank, lightened and balanced rotating parts, H-beam conrods, forget pistons, heavily flowed big-valve head? something like a 300 degree cam? lsd? how did you get it down to 700kg? my racer is still 780kg. | ||

Expert Posts: 4458 Location: Jelling, Denmark | migliacars - 21/1/2016 5:02 PM https://www.youtube.com/watch?v=kJ0IY8yf0Z8 this is before we owned it, there is was 1380cc n/a https://www.youtube.com/watch?v=AiI5k6d01lg this is her with me driving it with the 1380cc n/a the car came to us in 2004, pretty much as it is now chassis wise in fact i think we made it a tad heavier. the head is a 7 port which we ported to suit the boosted engine we built. as for the spec yes there is a dogbox and a lsd in there, as for the engine its not heavyly modded there is no crank better than a standard unit again were worked it to suit what we needed. the only thing that is a must is a set of arrow rods. The idea was to build a fast powerful low reving engine that would do a season with no hassle. as we have had such success with this unit im going to do a big power version. oh the metro is a real giant killer its always there with the fast lads right at the front, Its great to see people in amazement when they see the A series in there. I think I have seen that car in pictures before, at least one with the same carb/airfilter setup. if 210 crank bhp isn't big power it will be interesting to see what is big power to you  I raced in hill climbing several seasons (with half the power of you) with the standard crank aswell and yes it works really well but then again it is a steel crank unlike the old mini ones. mine finally had to be changed due to to large tolerances on the trust washers +30 to much unfortunately. other than that it was good. now I am using a turbo crank. yes the arrow rods looks really nice, but if you smoothen and polish the standard rods how much power do you think they will take? I can easily understand that its a giant killer, with that power to weight ratio its in escort bda/bdg territory and they are really really quick cars. | ||

Expert Posts: 4458 Location: Jelling, Denmark | here are some pictures of the two metro cranks I have been using. normal metro crank (CAM6232):  early turbo crank (CAM6581):  regarding old cranks I am talking about some of the mini cranks from before metros. everyone I talk to, people who race minis and the guys that reground cranks for me tells me that the CAM6232 crank is of much better steel and lasts longer than the old mini cranks, although it have to be said that I haven't tried racing with the old mini cranks. | ||

Expert Posts: 4458 Location: Jelling, Denmark | migliacars - 22/1/2016 9:40 AM big power !!!! i think well pretty sure that i can do 200 at the wheels, the engine at press has the wrong cam in it very restrictive so a big cam will be looked at and ground to the specs we shall require, also bigger injectors will help at the top end, and more boost, its just if the engine can take it for 20 mins at a time!!! rods. not sure what they can take tbh, i had a set modified by a certain self proclaimed A series expert in a full race 5 port so power wasnt big, it lasted 2 mins on a test day at cadwell park before 1t let go and took out my whole engine.... this was well before we started building our own units!!! so for the sake of £800 i just buy the best.... weight the metro uses carbon fiber doors and boot fiberglass bonnet and wings with a special detectable front end/bumper/splitter 200 at the wheels certainly is big power will be interesting to see when you have it build maybe one of your rods in that engine was bad. but yes for ease of mind when doing a big power a-series the arrow rods are nice. alternatively you could get some rods crack tested to be sure that you had 4 good rods. carbon and fibreglass will help on the weight I'm not allowed to use that as its supposed to be a historically correct series I race in. | ||
