An In-Depth Look at Crankshafts
In every aspect of an engine, strength is a very critical factor in the life span and performance level that it can achieve. One place in particular where strength is the most important consideration is the crankshaft.
Lunati LS Voodoo Crankshafts Now in Stock-Stroke Configuration
Lunati has recently added stock-stroke Voodoo series crankshafts to its lineup of GM LS Gen III/IV cranks. These 3.622″-stroke crankshafts have a standard-length snout and come with the choice of 24- or 58-tooth reluctor wheels.
High Performance Diesel Crankshafts, Connecting Rods & Pistons
Most stock Cummins, Duramax and Power Stroke engines can safely handle cranking up the turbo boost to produce 500 to 600 or more horsepower. But once you get to get up around 700 to 800 horsepower in an otherwise stock motor, things start to break and upgrades will be necessary.
Internal Affairs – Diesel Crankshafts and Rods
Despite having similar appearances, a diesel crankshaft has some primary differences from its gasoline counterparts. A gasoline engine uses a spark to ignite the fuel. A diesel engine, operating at a much higher compression ratio, uses the heat produced by compression to ignite the fuel. Diesel engines typically have a longer stroke than the bore diameter, so to handle this load, diesel crankshafts are much larger physically.
K1 Crankshafts and Connecting Rods for GM LS Engines
Forged from 4340, the tough, shock and impact resistant alloy steel, K1 Technologies has introduced a new range of high-performance crankshafts and H-beam connecting rods for racing and high performance LS engines.
Replacing Crankshafts, Connecting Rods and Bearings
The crankshaft, connecting rods and bearings are extremely important in every engine build, whether mild or wild, because they convert the reciprocating motion of the pistons into rotational torque. The longer the stroke, the greater the leverage effect and the greater the torque output of the engine. There are three things that need to be
Crankshafts and Bearings for Street Performance and Racing
The crankshaft and bearings are the foundation of any engine. The type of bearing and crankshaft materials that are used, their strength properties, fatigue resistance and ability to handle high torque loads ultimately determine how durable the engine is and whether it goes the distance or self-destructs. Most engine builders have strong opinions and
Lunati Voodoo Crankshafts
The backbone of your engine and the foundation of your bottom end is the crankshaft. Voodoo Crankshafts from Lunati are engineered from 4340 non-twist forged steel that is known for its durability and strength in high-performance applications. All Voodoo Cranks are nitride heat treated with micro-polished journals to add even more durability. Lightening holes in the rod
Custom Crankshafts and Connecting Rods
As an engine builder, you get to decide what parts go into the engines you build. If you’re rebuilding a stock engine to stock specifications, you’re probably going to use a reconditioned stock crankshaft and connecting rods to keep costs down. There’s no reason to upgrade these parts because they should be adequate for the
Engine Bearings and Crankshafts: Best Friends Forever (BFFs)
Bearings appear to be such simple engine components. On the surface, they’re just half-circles of metal whose only purpose is to reduce friction between and support moving parts. The engine bearing has to establish and maintain a film of oil between moving and stationary parts to prevent wear to expensive engine components. They look like
Clearing The Confusion Concerning GM Gen III Crankshafts
Both Doug Anderson and I have written a number of articles and columns about these engines, but for some reason I continue to hear about the difficulties. So it’s time to go back to the basics, start from the beginning and review the old and add some new things that have come along. The first
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
Drag Racing Crankshafts
With photos and words by Steve TempleAs any experienced engine builder already knows, a drag race engine is made up of hundreds of precision parts bolted together to form an assembly that spins at a furious rate in order to propel its vehicle to victory. Meeting this challenge requires that all those parts going into
