Improving Your Mini Cooper Gas Mileage

by Don Racine
Most engines (and all Minis) use an electric spark to start the burning of the fuel/air mixture which in turn powers the car. If the engine is to run properly this 'electric spark' must happen at the exact right time.

Mini Cooper Verto Clutch Information

This article has been written owing to the increasing amount of people who ring Mini Spares stating that their 1275cc Injection type Mini will not start after fitting a new clutch, especially when they have purchased the parts from another supplier, usually a motor factoring company, rather than a Mini specialist.. There are 2 types of Pressure plates, namely AP (Automotive Products) and Valeo.

General: Camshaft Drive Systems If you are working on your engine and you want to do it right then you should consider how you are going to drive the camshaft. People often spend a lot of time picking the camshaft and then ignore the exact reason they spent so much time picking the cam. Driving the cam and controlling the timing relationships between the cam and the crank is what camshaft drive systems are all about. It makes no difference what the cam does if it does not do it in sync with the crank and pistons. The stock system on many 848, 948, 998 and 1098cc engines is a single chain drive between the crank and cam. The 'S' and some 1275 have a much better "duplex" chain. But even those do wear out! The best judge is to check it while you are taking it apart. With the timing cover off the engine rotate the crank a slight amount back and forth. The camshaft must move the exact distance at the same instant! The least expensive but better than an old one is a stock cast gear and chain set, This budget standard cast duplex gear and chain set is the next step up, for road use only. Fitment of an uprated cam drive system is essential when building a performance engine. Timing scatter induced by the standard set up can reach up to 15 degrees once the single row chain has stretched, which it does after only a few miles. This scatter not only affects the cam timing, but also the ignition, the distributor being driven by the camshaft. Power loss suffered by this phenomenon is substantial. Replacing the standard single row (simplex) system with a dual row (duplex) system greatly reduces the problem; use of a toothed belt system all but eliminates it. The belt system vastly reduces valve train noise and also helps damp out some of the odd harmonics generated by the 3 main bearing 'A' series engine. It is also extremely important to time any cam in to its required setting to obtain maximum performance, especially with performance cams. The 'dot to dot' method can, because of manufacturing tolerances, be out by as much as 15 degrees. Anything above 2 degrees out and power suffers -- most noticeably in small bore engines. In race engines you probably lose 1 hp for every degree the cam is out, more when over 6 degrees!
