Addressing the void of a Pro Stock Suzuki crankshaft fit to withstand the punishment of the 1/4 mile, we proudly announce the PSM Billet Crankshaft by Vance & Hines Racing. Our engineers focused on every painstaking detail, dedicated to designing and developing a superior product from start to finish.

Which is better forged or billet crankshaft?

With a forged crank, the forging process creates an interwoven grain structure. With a billet crank, the grain structure just runs parallel with the crank. ... Dwayne Boes Of Callies"If the exact same material is used for both, a forging is stronger than billet because the grain flow is upset and relocated.

Where are Callies Magnum cranks made?

Callies make 5 types of crankshafts. DragonSlayer / Magnum / Magnum XL / UB - which is forged and machined in USA. Want to spend less than 1,000.00 in a crank, you will end up with a Chinese forging, no matter what brand.

What is the best crank material?

In the high performance crankshaft world, the nickel-chrome-moly alloy SAE-4340 (AMS-6414) has been a favorite in both forged and billet applications. It is used because of its very high strength and fatigue properties, coupled with good ductility and impact resistance at high strengths.

How are billet crankshafts made?

Billet cranks are CNC machined from a solid bar of steel such as EN30, 4330M or other high-grade alloy. Unlike a forged crank that has to be heated, stamped and twisted into shape in a high-pressure forging press, a custom CNC billet crank is machined at room temperature to final dimensions in a CNC machine.

What is billet steel?

Billet metal is a solid length (often in a square or circle profile) of material that has been extruded into shape, either by continuous casting or hot rolling.

How much does a custom crankshaft cost?

Man, a custom crank will run you $2000 or so. Go the smart route and use an OTS 4.0 crank and open up the bore to get your 427. Its easy with a Dart block, the results are much better and the parts are readily available.

How much HP can a billet crank handle?

A typical small-block cast crank is good up to 500 hp, while a 4340 forging can take 1,500 hp. "Billet cranks are similar to forged cranks in that they also start out as a big ingot of steel.

Which crankshaft is stronger cast or forged?

Once heat treated, the forgings offer both superior tensil strength and improvements in elongation (essentially the amount of deflection before breakage). In terms of tensil strength, cast cranks start near 60,000 psi, but forgings can more than double this rating to (as high as) 125,000 psi.

Are scat cranks any good?

scat in a 454 is a safe bet in my opinion only. If one has a high reving motor than their forged steel cranks are a better choice and more than capable for the street and stress we put on them. The track may be a different story although many will/can attest that they have great success their too!

Why is billet so expensive?

Speaking of cost, why are billet parts more expensive than cast? Primarily it has to do with scale. Machining one part from billet isn't too expensive. The problem is that it doesn't get cheaper per part to machine one hundred parts, or one thousand parts, because you can still only make one at a time.

Is billet better than cast?

Billet aluminum is generally considered a stronger material than cast. Billet parts are made from a single block of material that is machined down on a CNC mill. The result is a gorgeous part that can be made to match an engineer's design with perfect precision.

What is stronger billet or forged aluminum?

Metallurgists agree that a forged piece of aluminum is stronger than cast or billet. The reason being, when the material is shaped under pressure, its 'grain' follows the same shape as the part. As a result, the product manufactured is stronger due to the continuous grain characteristics allowed by the forging process.

How do you tell if a crank is forged?

The best and most sure method for recognizing a forged crank is to look for the parting lines on the counterweights. A forged piece will have a wide, irregular rough patch. A cast component (shown) will have a very sharp, well-defined line where the mold was separated.

Do you need a forged crankshaft?

If your motor will see no more than 6000 RPM and is never sustained in that RPM range, then you have no need for a forge crank. Forged cranks are for people who can`t sleep at night.

How can you tell whether a certain part is forged or cast?

Forged parts are often tougher than cast parts. This can be determined by performing tensile tests on various areas on the parts. Additionally, the microstructures of forged and cast parts can be used to determine if a part was forged or cast. The microstructure of a cast part will have a more uniform grain structure.

What is the lightest SBC crankshaft?

The Crower Ultra-Light crankshaft is our lightest crankshaft. The Crower Ultra-light crankshaft's rotating mass is reduces utilizing Pendulum undercutting, lightweight profiling, gun drilled mains, lightening holes in all rod journals and a profiled rear flange for the lightest rotating weight.

How much HP can a stock 350 crank take?

Stock GM crank, assuming proper balancing and careful installation will take 400-450hp+ all day long with good rods and decent pistons.

How much power can scat H beam rods handle?

Those Eagle and Scat 4340 H-Beams are rated to like 1500hp if they have the ARP L-19 bolts.

How much is a crankshaft worth?

In order to avoid this, try and keep the crankshaft in the best condition possible. If not, you can expect to pay an average of around $2014 for a crankshaft replacement cost total. Replacing the crankshaft is generally a part of an entire engine overhaul job done at your mechanic's shop.

How is billet made?

Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. Billets are further processed via profile rolling and drawing. ... Centrifugal casting is also used to produce short circular tubes as billets, usually to achieve a precise metallurgical structure.

Where are billet Specialties wheels made?

From design to finishing, all processes take place in our 100,000 sq ft facility located in La Grange, IL, resulting in the highest quality products for your vehicle.

Where is billet used?

A billet is a section of metal used for rolling into bars, rods and sections. It can be produced with ingots or directly by continuous casting. Billets are used as raw materials or feedstock in extrusion, forging, rolling and other metal-processing operations.

Why is billet more expensive than forged?

The machining process leverages an expensive CNC machine to achieve precision by moving the parts around. The cutting process and moving of the block require a lot of time compared to the simple forged process. This explains why machined/billet lowers costs more.

Are billet lowers mil spec?

Billet receivers are not considered to be Mil-Spec because the manufacturing process, materials and dimensions can vary from the military call-outs. Due to the added thickness and custom designs, some Mil-Spec style parts may have fitment issues.
