SCAT Enterprises will be at SEMA this year! Come out to the Las Vegas Convention Center (3150 Paradise Road) from October 30-November 2 for the premier automotive specialty products trade show.

You’ll have the chance to view products from each of our brands: SCAT Crankshafts, Procar by SCAT and SCAT VW. We will be able to answer any and all questions you have.

*Note: SEMA is a trade-only event and is not open to the general public.

SCAT Crankshafts products were featured in the August issue of Mustang Monthly Magazine! Read about how to get 400 HP with a small-block Ford here.

Mustang360 just wrapped on their Week to Wicked 1967 Mustang Fastback build! The awesome ride features Procar by SCAT seats. Check out their final day of building, here, and the rest of the progress, here.

Back in May, EngineLabs Magazine asked readers to send in questions for SCAT Crankshafts’ very own, Tom Lieb. Now, he’s answered 10 questions related to all things crankshafts, connecting rods and pistons.

Check out one of the questions and answers:

I installed a Scat 383 internally balanced forged stroker kit in a first-gen SBC 350 four-bolt main block a while back. Sometime later, I was told by a keyboard cowboy on one of the car forums that the Scat crank required the use of a specific harmonic balancer which I was not using. My engine builder never said anything and I’m curious if there is in fact any problem running a Fluidamper harmonic balancer with a Scat 383 forged crank. If so, what is the preferred balancer?

– Steve Hayes

Tom Lieb: Steve, SCAT cranks do not require a specific harmonic balancer. Like all cranks they require a balancer that is properly designed for a performance engine. 90-percent of crank breakage in the front half of the engine is due to a balancer that is too large in diameter, too heavy, has moving parts, and cannot be balanced with the crankshaft. Moving parts include both fluid and mechanical pieces. These dampers cannot react fast enough to rapid acceleration and deceleration. Therefore, they create harmonics that will eventually fatigue a crank and break it. These dampers were designed for industrial applications that run constant speed in narrow RPM ranges. So, that being said, the smallest diameter, lightest weight, and an elastomer design is best.

SCAT Crankshafts was recently featured in a Chevy Hardcore article all about engine balancing! Gain some insight from Tom Lieb as he discusses the importance of crankshaft balancing to make your ride run smoother.

When an engine is running and the crankshaft is rotating, the connecting rod and piston assembly are reciprocating (traveling up and down). Balancing a crankshaft is a matter of managing rotational and reciprocating movement. Both directions of movement need to be considered when balance is determined. But, how is balance achieved?

Generally speaking, it is done by taking away or adding metal to the counterweights. But, to find balance, you need to know bobweight. The bobweights are actual weights that are attached to a crankshaft’s rod journals when balancing, to simulate the weight of the rod and piston assembly. With the bob weights in place, the crank is ready to be spun on a balancing machine. While there are simple formulas to calculate the amount of bobweight needed, there is a lot that these calculations fail to consider.

SCAT Crankshafts was recently featured in the April issue of Engine Builder Magazine! Here’s an excerpt from the article, all about balancing rotating assemblies:

Since balancing has become more critical, it is important to know what constitutes a balanced rotating assembly or not. If you look down the nose of a V8 or V6 crank, you’ll notice that the counterweights are like a corkscrew and that’s because they react with each other through the system of the crank itself. If you understand that then you can understand where to remove the metal.

‘When a crank is too heavy in one place, that means it’s too light in another,’ says Tom Lieb, founder of Scat Enterprises. ‘Being able to look at a crankshaft and understand where that weight is and make those decisions – not everybody can do that.’
