OVER 35 YEARS WORTH OF KNOWLEDGE
New builds, development, testing....
First steps to a winning engine...
We start the process by meeting with the customer to discuss their plans and racing schedule. After we have discussed such requirements we will work on the engine specification and look closely at the classification rules and regulations.
The build process takes many steps along the way, usually starting with the machining of components along with many tolerance checks. Once we have the majority of machining complete then a pre build of the short engine takes place. This determines finished piston heights and other dimensional clearances giving us the data to finish machine the final components to our exacting standards. The clutch assembly will be assembled, carefully centralised and finally dynamically balanced along with crankshaft, conrods, pistons and damper assembly.
UNIQUE CAMSHAFT PROFILES......
Particular attention to camshaft profiles and timing is applied at this stage, this along with cylinder head design and rocker geometry is of great importance on all A series race engine builds and is where the last few BHP is gained giving you the very best available.
The transmission is precisely prepared, machining of the gear casing for bespoke differentials, gear train and transfer gears now takes place. Once a trial build to check all tolerances and pre-loads has taken place the transmission is finally assembled.
The cylinder head goes through around 3 days of extensive modification. Ports are modified to a special profile along with the combustion chambers. Special valve seats are cut on our cylinder head centre, a final reface on our CNC mill is carried out to achieve the correct compression ratio for the engine.
Once the engine is fully assembled we install on a dyno and bed the engine in. Many checks and tests are carried out during this period. Once we are happy a comprehensive set up is carried out. Once complete the engine is ready for delivery to the customer.
COME AND SEE....
We want all our customers to be competitive and happy with their engines. We can offer mid season checkups of your race engine and end of season rebuilds to evaluate and further develop for the future. All of which is very important part of keeping you ahead of the competition.
We have a very experienced team on hand so if you wish to call us to discuss your engine first please pick up the telephone and speak to us. We can run through all your options and arrange a meeting to go through the specification in more details along with demonstrations of the internal components to give you a better understanding of how your race engine will deliver unbeatable power.
For further information or quotations please contact us and we will be happy to advise further.
Historic racing seems to be ever growing both in the UK and throughout Europe. The Mini always puts on a great display battling with the likes of Lotus Cortinas, Ford Mustangs and Falcons just to name a few.
The usual configuration for this application is of course 1293cc, this is obtained by utilising a standard stroke along with a first over bore of 0.020". Steel crankshaft, conrods, together with our lightweight forged pistons brings together the main rotating assembly. The cylinder head is our special FIA race version along with forged rockers. The transmission consists of a 4 speed dog engagement gear kit, LSD differential with a straight cut drop gears and final drive. Our lightweight clutch assembly and front pulley finishes the engine package. H4 bespoke carburettors, distributer, coil, leads etc are all supplied. The engine is dyno run, set up and ready to go.
Here's a video of our works Historic Mini powered by one of our FIA engines.
Mini Miglia has been at the forefront of Mini racing for many years now, it’s a highly competitive race series and has the need for constant development and strong powerfull engines.
The engine in brief:
The Miglia utilises a first over bore giving a capacity of 1293cc running a compression ratio of 11.0:1, 1.3 ratio rockers and standard Cooper ‘S’ valve sizes within one of our modified Miglia spec cylinder heads. Our steel crankshaft with a standard stroke of 81.33mm is used along with our steel conrods which are fitted to our exclusive forged lightweight pistons. The camshaft is limited to the original STR 930 profile, adjustable Vernier timing, along with a whole array of bespoke parts from our extensive catalogue. Our 4 speed dog engagement gear kit is used for the transmission giving ultimate reliability and performance.

With the popularity of historic rallying throughout Europe many drivers are now returning to the classic Mini Cooper S. Here at MED with our 30 years experience of building rally engines we can the offer the discerning customer the perfect engine unit for this very demanding discipline.
Within the UK the engine would be a 1293cc fitted with either twin SUs or a single 45 DCOE Weber, but for our Irish contingent our NEW 1495cc full house unit would be the order of the day. Our engines have had years of development put into the cylinder head design with hours spent on the flow bench to achieve the best in both valve design and port modification to achieve a high air flow which is of paramount importance for a rally engine. We have also received great assistance from Piper Cams in developing the ultimate range of camshafts for rallying to assist.
