How do you identify a SCAT crankshaft?
The SCAT name is cast in raised letters on the arm of the first counterweight. This helps identify a certified SCAT Crankshaft.
Are SCAT crankshafts forged?
SCAT’s custom crankshafts are available in Billet and Forged Alloy materials.
What are the two different types of crankshafts?
The crankshaft There are two types of crankshaft, the monolithic type (Fig. 8.1), used for multi-cylinder engines, and the assembled type (Fig. 8.2) fabricated from separate elements, which is mainly used for motorcycles.
Who owns SCAT cranks?
Tom Lieb
OUR ROOTS. Go back to 1964, when owner and founder, Tom Lieb, planted the seeds for what SCAT has become today: one of the most respected and innovative manufacturing companies in the automotive aftermarket.
Are SCAT cranks balanced?
Scat sells them as either unbalanced, externally balanced, internally balanced, or for one-piece-rear-main small-block Chevys, balanced internally for the front and externally for the rear.
Why is a flat-plane crank better?
What Is the Advantage of a Flat-Plane Crank? Due to their lightweight design, flat-plane cranks have excellent primary balance properties, so there’s no need for the large counterweights found with cross-plane cranks. Less weight means less inertia, smaller size, and increased acceleration (revs faster).
How much horsepower can a cast crank handle?
For small-blocks, a safe limit for a cast crank is 500 hp and a maximum of 6,500 rpm. With big-blocks, their bigger mains will handle 650 hp. We’ve seen cast cranks in turbo motors take over 2,000 hp, but we don’t recommend it. These days, 4340 is the standard for forged cranks.
Are SCAT cranks Made in USA?
SCAT has a 42,000 square foot manufacturing and distribution facility in Redondo Beach, California, home to over 70 major pieces of equipment including CNC machines, rod honing machines, crankshaft grinding and polishing machines.
Where are Molnar crankshafts made?
All Molnar rods are finished in the United States at the Molnar Technologies shop in Michigan. Critical rod dimensions are are held to very precise tolerances of +/- . 0001 of an inch, which is the tightest tolerance you will find in the performance and racing aftermarket.
What is Bob weight crankshafts?
One of the references you will run across is something called bob weight. This spec refers to the mass located on a single crankshaft journal that includes both the reciprocating and rotating weight portions of the entire assembly.
Do Nascar engines have flat plane cranks?
The engines in Nascar Sprint Cup cars are 90-degree pushrod V8s, just like those that have powered many vehicles on American roads for more than 50 years. But today, the engine under Jimmie Johnson’s hood is a custom-made 850-hp 358-cubic-inch thoroughbred that’s optimized to run flat-out for no more than 1000 miles.
Is Ferrari flat-plane crank?
Flat-plane crankshafts are generally associated with European sports cars such as Ferrari and Lotus V8 engines, and cross-plane cranks with American manufacturers.
What is the function of a crankshaft?
A crankshaft is a shaft driven by a crank mechanism consisting of a series of cranks and crankpins to which the connecting rods of an engine is attached. It is a mechanical part able to perform a conversion between reciprocating motion and rotational motion.
What engine has a cast iron crankshaft?
Cast iron crankshafts are today mostly found in cheaper production engines (such as those found in the Ford Focus diesel engines) where the loads are lower. Some engines also use cast iron crankshafts for low output versions while the more expensive high output version uses forged steel.
What type of steel is used to make crankshafts?
Carbon steels are also used, but these require additional heat treatment to reach the desired properties. Cast iron crankshafts are today mostly found in cheaper production engines (such as those found in the Ford Focus diesel engines) where the loads are lower.
Are your crankshafts fully customized?
These crankshafts are fully customized to your needs. Like our Forgings, each crankshaft is skillfully machined, precision finished, Ion-Nitrded & Heat-Treated for superior quality, extreme strength & durability. Our machining abilities cover anything within 43” Length x 10” Diameter.
