How Piston Rings Affect Horsepower
The rings seal the pistons to prevent air and oil from being drawn past the rings into the combustion chamber during the intake stroke. During the compression stroke, the rings make sure the air/fuel stays in the combustion chamber and is fully compressed before it is ignited. During the power stroke, the rings prevent pressure
Crankshafts and Bearings for Street Performance and Racing
Most engine builders have strong opinions and brand preferences when it comes to choosing a crankshaft and bearing combination for a performance engine application. Their preferences (and prejudices) are usually based on years of experience, both good and bad. Many subscribe to the philosophy that “if it isn’t broke, don’t fix it!” Consequently, if they
CSI: Engine Bearings: When Good Bearings Go Bad
Engine bearings have the dual function of reducing friction between a rotating part of the engine (the crankshaft) and the stationary part (the main caps and engine block) and supporting the crank. Because of the stresses caused by the explosions inside the internal combustion engine, the bearing material must be extremely strong, so a durable
Race Engine Pistons and Rings
Cubic inches is the name of the game today. The performance piston market is being driven by bigger bore blocks and stroker crankshafts. A few years ago, a 540 cubic inch motor was a monster motor. Nowadays, some professional drag racers are running engines as large as 850 cubic inches, and 600-plus cubic inch big
High Performance Piston Rings and Cylinder Finishes
Today’s performance ring sets are thinner, lighter and more conformable than ever before. Thinner, low-tension rings reduce friction for more usable horsepower. Less weight reduces ring groove pound out. Narrower rings also allow tighter tolerances and less blowby. All very good things when you’re building a performance engine. But they also require rounder, straighter cylinder
Lord(s) Of The (Piston) Rings
“He who breaks a thing to find out what it is, has left the path of wisdom.” – Gandalf, Fellowship of the Rings. This is certainly not the case with piston ring technology, although Gandalf from the Lord of The Rings never directed his comments towards engine builders or piston ring manufacturers. Piston ring manufacturers
