Investment cast vs forged crankshaft

Both tuftriding and nitriding feature surface hardening though chemical compounds. Tuftriding involves dipping the crank in a heated cyanide compound while the nitriding process features the introduction of a chemical gas in a heated furnace. 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, psi, but forgings can more than double this rating to as high as , psi. The elongation rating of factory cast cranks is an indication of just how brittle they are. The final piece of the puzzle to consider is the finishing process. Things like quality of manufacturing, accepted tolerances, the machine used, and even the employee doing the work.

But some general things to look at would be the different ways to shave weight, reduce windage, and maintain balance. While technical talk is all well and good, what does it all mean to the average consumer? With the Internet abuzz with the ability to exceed 1, hp with factory cast cranks, why on earth would anyone need to spend the money on a forging?

Crank strength is much more than a function of what it will survive on a single hero run. Factory cranks were designed by the OEMs to last , miles or more literally millions of cycles and that life span is a function of more than just tensil strength or elongation.

It is possible for even the wimpiest of cast cranks to survive indefinitely if run at lower engine speeds and power levels. If you have a hard time grasping this concept, think about how far you could walk at a slow pace versus run at full speed. Run at full speed and load, the cycle life of a crankshaft quickly diminishes, which is why a horsepower small block run in a daily driven street Camaro might work well with a cast crank, but the same motor powering a pleasure boat would require forged components.

The time spent at high load and rpm determine the need for a forged crank every bit as much as a peak power level. So if you have a performance engine, you now know that a forged crank is the way you should go for longevity, but which one? The difference comes in the heat treat.

If you are running a normally aspirated engine, or something with mild boost 10 psi or less , or a very light shot of nitrous, then your engine will be happy with the lower priced Voodoo crank. It can handle the higher horsepower and rigors associated with high-boost and heavy nitrous applications. There is some more work on the finishing process for the Signature Series as well, like wing cutting the counterweight to reduce windage, and on big-block Chevy cranks we center counterweight them to maintain the balance.

No discussion on crankshafts would be complete without covering stroker cranks. Stroker cranks are simply cranks equipped with increased stroke length the distance the pistons moves from the bottom to the top of the bore. McLaughlin says that the majority of cranks that come out of Lunati are stroked. The benefit of increasing the stroke length is increased displacement, which aides in power production. It is easier to make power and especially torque with increased displacement.

The difference between a small block and a stroker can be 50—60 lb. Having an extra 40—50 horsepower at the redline is good, but having and extra 50—60 lb. Build your own custom newsletter with the content you love from Street Muscle, directly to your inbox, absolutely FREE!

Nonetheless, they're a far cry from the ultimate durability of an aftermarket steel crank. There are other materials involved, but they are used to make sure everything mixes together properly and don't impact strength.

The most basic aftermarket-grade steel is , which boasts a tensile strength of about , psi. This material used to be-and to some extent still is-an excellent choice for racers on a budget, but is less common than in years past due to the increasing affordability of premium alloy cranks. These include and forgings, which have tensile strength ratings of approximately , psi and , psi, respectively. Engine builders and crankshaft manufacturers universally accept as the ideal alloy for strength and durability.

Twist vs. Non-Twist Forging Forged cranks are pressed into place on a die, but there are two different techniques used to accomplish this. The simplest method is to forge one of the crank throws at a time in a flat forging die. The crank is then twisted, and the die forges the next throw.

Conversely, in a non-twist forging, all four throws are forged simultaneously, which requires a more complex die. Non-twist forgings are said to reduce internal crankshaft stresses during the manufacturing process, but not everyone's buying it. It's more of a marketing thing. Heat Treating In addition to materials, and casting or forging techniques, heat treating can greatly impact the strength of a crankshaft.

Nitriding is the most prevalent method of heat treating used in aftermarket cranks, where ionized nitrogen is vacuum deposited onto the crank surface in an oven. By penetrating. The OEs usually favor induction hardening over nitriding, which results in deeper penetration into the metal surface.

This process uses a magnetic field to heat the surface. However, induction hardening penetrates more deeply, which enables turning down the journals once or twice during rebuilds before having to heat treat the crank again. Knife-Edging Does knife-edging a crank's counterweights really reduce windage and increase power? Not everyone thinks so. A bull-nose rounded leading edge is the most efficient, like the bow of a ship.

Overlap Just as the term implies, journal overlap is simply how much of a crank's main and rod journal diameters overlap each other. As stroke is increased, moving the rod journals farther away from the main journals reduces overlap and compromises strength and durability. Likewise, smaller rod and main journals reduce bearing speed and friction, but also reduce overlap.

Billet Or Forged? Although we've clearly outlined the hierarchy of the various grades of castings and forgings, we haven't declared whether billet cranks or their forged counterparts offer the ultimate in strength. Quite frankly, we don't know the answer, and we won't even attempt to make an educated guess. There are compelling arguments for each from a host of credible sources, so we'll print their words, and let you decide.

Alan Davis Of Eagle: "People think billet is stronger than a forging, but that's not true. Billet got that reputation from back when forged aftermarket cranks weren't readily available, and billet was the only way to go for a performance crank. 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.

Billet is a better option if you need a custom one-off crank since it doesn't require expensive tooling equipment. On the other hand, the ton presses required for forgings cost at least six figures, so they're more suited for large production runs. Tom Lieb Of Scat: "A forging is not as strong as billet because the forging process stretches and shears the grain structure.

A forging starts out as round bar of metal and gets twisted and turned to make the rod throws. What used to be centerline of the bar is now offset, and the grains get stretched, traumatized, and weakened, although some sections of it are substantially stronger than in a casting. With billet, there are no stress riser areas because the grain structure runs parallel to the length of the entire crank.

Forgings are stronger than billet in bolts and axles because the metal isn't being stretched and sheared. 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. However, it's much easier to get special alloys in a billet material. However, when you start reducing the overlap with long strokes and small rod journals to reduce bearing speed, billet comes out on top.

In our motors, billet lets us get away with less journal overlap. When it comes to cranks, this still holds true, but to a lesser degree. The efforts of engine platform-specific diehards have yielded a specialty market of just-released steel cranks in some markets. In others, there are specialists for each engine family that can modify factory cranks to get you the extra displacement you crave.

Of course, companies like Winberg, Bryant, and Moldex will make a custom crank out of billet for any engine, but we'll assume most hot rodders are working with a real-world budget. Pontiac It's been 30 years in the making, but Pontiac enthusiasts now have both aftermarket cast and forged cranks at their disposal.

In the late '90s, Butler Performance teamed up with Eagle to produce the first aftermarket Pontiac crank, a cast-steel 4. Just this year, Butler Performance released forged cranks in 4. The company also offers 4. Buick Unfortunately, the aftermarket hasn't stepped up with a new Buick crank design, but there are still options for increasing displacement by a good margin. It's better to offset grind the crank to 4 inches, in which case you can still externally balance the motor. Oldsmobile In the walk of big-block Oldsmobiles, there's the and the Noted Olds engine builder Dick Miller says that all motors came equipped with forged steel cranks from the factory, while the number of s with steel cranks are less than The is the most common engine amongst Olds buffs, which features a 4.

These cranks can handle up to hp. Scat and Eagle both offer cast-steel cranks with strokes ranging from 3. I've put over hp through a cast Scat crank without any problems.

A cast iron or nodular cast iron crank is probably enough for most mild street motors. Higher horsepower and higher sustained RPM cause the stress on a crank to increase. Most aftermarket crankshaft manufacturers will have an approximate horsepower level that they rate their cranks at.

One thing to think about is that depending on the alloy used, a cast steel crank can be almost as strong as a forged crank. Just check with the crank manufacturer to see what horsepower level their crank will handle and make sure that is the same or more than what your engine will produce. As far as forged versus billet, it depends on who you believe on which one is stronger, but given the price of a billet crank, there should be some advantage to it.

There is a theory that while forging aligns the crystals of the steel, all the bending that is needed to make the final shape breaks some of those. Instead it is machined to the final shape. If you are looking at forged cranks, then you are probably working with someone who has a preference based on their experience and it would probably be good to follow their advice.

Factory forged cranks generally rely on plain carbon steel, but material upgrades include chromium, molybdenum, and finally nickel chromium alloy. The one downside to forged cranks is the need for heat treating. Where the journals on cast-iron cranks becomes work hardened during the machining process, forged steel cranks are not so lucky, and must instead be heat treated after machining.

Common heat treating methods for forged cranks include induction hardening, tuftriding, and nitriding. Induction hardening relies on a high-frequency magnetic field to quickly heat the surface before quenching. Employed by most OEMs for their forged cranks, induction hardening offers the benefits of cost, speed, and deep surface penetration meaning it can be re-machined without the need to re-heat treat.

Both tuftriding and nitriding feature surface hardening though chemical compounds. Tuftriding involves dipping the crank in a heated cyanide compound while the nitriding process features the introduction of a chemical gas in a heated furnace.

Unlike with pistons, there are more materials to work with when talking about cranks. The difference between cast iron and nodular cast iron is the shape of the graphite particles in the iron. Cast iron is not just iron, pure iron is too soft to be used as a crankshaft. In regular cast iron, the graphite particles are flakes. In nodular cast iron, they are spherical nodules. This gives the cast iron more strength and flexibility. Cast steel is stronger due to the fact that steel is stronger than iron.

To make a cast crankshaft, they heat up iron or steel until it is melted then pour it into a mold, the same as with cast pistons. Like cast pistons, there is less finish machining to do so they cost less. With forged steel cranks, a metal bar is heated until it is soft then pounded into the rough shape of the crankshaft.

From there it is machined into the final shape. There is more machine work involved, along with the cost of the forging equipment it makes for a higher cost of the final piece. There are different alloys of steel used, that give a crank different levels of strength.

There is one more option for manufacturing a crankshaft, and that is a billet steel crankshaft. To make them, a much larger bar of steel is forged into a cylinder shape as large as the total diameter of the finished crank, then it is machined to the final shape.

As you can imagine that is a lot more machining and the final cost reflects this. So what kind do you need? As it often does, it depends. A cast iron or nodular cast iron crank is probably enough for most mild street motors. Higher horsepower and higher sustained RPM cause the stress on a crank to increase.
