Engine Balancing

Balancing goes hand-in-hand with performance engine building. Balancing reduces internal loads and vibrations that stress metal and may eventually lead to component failure. But is it worth the time and effort for all engines not just race applications.
From a technical point of view, every engine regardless of the application or its selling price can benefit from balancing. A smoother-running engine is also a more powerful engine. Less energy is wasted by the crank as it turns rotating and reciprocating mass into horse power. Reducing engine vibration also reduces stress on engine components.

The benefit to balancing your engine is a great policy to keep your investment secure. This day in age a secure investment is UN heard of.

TEM Machine Shop not only balances we have upgraded our equipment to a digital standpoint. Our on analog machine was a great tool for the 19th century. By going digital we were able to increase our tolerance from a 14 gram window into a 100tn of a gram.

A crankshaft with only 2 ounces of imbalance at 2,000 rpm will be subjected to a force of 14.2 lbs. At 4,000 rpm, the force increases to 56.8 lbs.! Double the speed again to 8,000 rpm and the force becomes 227.2 lbs.
