Engine, crankshaft and complete driveline. Balancing is the key to a reliable, smooth racing engine resulting in maximum power output. An incorrectly balanced driveline results in stray centripetal forces on every rotation, sapping power and creating destructive vibrational forces.
The dynamic balancing machine, and more importantly our years of experience using it, allows us to very accurately and precisely balance crankshafts, clutches, flywheels, flexplates and indeed the whole driveline assembly together. To get the best results, we prefer to balance the whole driveline at once. This means the crank, flywheel, clutch and cover all bolted together spinning on the machine.
When a component is out of balance, our machine directly indicates at what position the rotating object has an imbalance, and in what plane. A few calculations later, and either weight is removed from the object, or "heavy metal" carefully added in exactly the correct position to overcome the moments of imbalance. The process is continually repeated until as near perfect balance as possible is acheived. The process of balancing is a long and accurate process, but very rewarding, for both customer and the person operating the machine!
Piston and Rod Balancing There is no point in spending time and money balancing all the spinning components if there is imbalanced weight hanging off it! As part of the balancing process, all the pistons and rods cam be balanced too. The lightest rod and piston is found and the rest of them are hand fettled and finished so their mass matches exactly.
Any race engine that is built without being balancing, is not truly a racing engine. Please feel free to give us a call or email to discuss your requirements. Remember that we can balance anything that spins! - not just engine components.
Mapping, Development and Power Curvers - Our state of the art, computer controlled dyno is our most important asset. It allows us to test and develop improvements and adjustments, until the desired horsepower or driveability is reached. This can save months in development time when previously each modification would have to be tested on the track!
Of course, maximum horsepower is not always the order of the day, as each application requires different types of perfomance. For example a Big Block chevy built for short oval shale racing needs a vastly different power curve from the same engine built for drag. The dyno alows us to taylor each engine to its driver, and the sport it will be competing in.
All our engines are run on the dyno as part of the race engine building service. The computer controlled runs means that the dyno can mimic real world simulations and races meaning we can be confident that the unit has been correctly run in, performs to expectations, and is ready to race as soon as it leaves our workshops.
Mapping Engine management systems are becoming more and more popular on racing engines. The use of a standalone management system means that very precise control of the engine can be gained. By spending time with the unit on the dyno we can maticulously set up the fuel and ignition maps in relation to throttle position, and ensure that the engine is providing the maximum power possible, all of the time.
