Is wiseco a good piston?

Absolutely. Wiseco pistons are among the finest powersports pistons available. Unlike most OEM or other aftermarket pistons, Wiseco pistons are forged in-house at their own manufacturing facility.

Which is the best piston?

4032 Forged Aluminum Pistons

Forged pistons are the strongest on the market. The manufacturing process is different from a cast piston, because the aluminum is not molten like that of a cast piston. Instead, a hot aluminum ingot is forced into the simple mold.

Are Wiseco pistons forged?

Wiseco domestic auto and sport compact pistons are forged and machined in-house and receive a full compliment of power enhancing features.

Does Wiseco own JE Pistons?

Performance Motor-sports was formed in June 1999 with the merger of Wiseco and JE Pistons. Wiseco and JE continued to operate independently in their respective markets but supported each other痴 development through sharing of best practices.

Is Wiseco a good brand?

Absolutely. Wiseco pistons are among the finest powersports pistons available. Unlike most OEM or other aftermarket pistons, Wiseco pistons are forged in-house at their own manufacturing facility.

Are Wiseco pistons cast or forged?

A Wiseco piston is forged by taking a solid aluminum billet or puck and pressing it into shape using massive hydraulic pressure. The compression process ensures the structure of the metal itself remains uniform, and therefore much denser and stronger.

Are forged pistons better than cast?

In the casting process, the alloy molecules are free to settle where they please, creating a random grain structure, and opening up the potential for weak spots. This is why forged pistons are fundamentally stronger than cast.

What are the advantages of forged pistons?

The main characteristic that makes forged pistons excel in high performance applications is strength and durability. The high silicon content of cast pistons makes them brittle compared to forged pistons. Silicon gives the metal lubricity and is mixed in the alloy to limit heat expansion.

Do forged pistons last longer?

The wear on the cylinder comes from the rings dragging up and down the wall - not the piston. A block with forged pistons will last just as long as a block with cast pistons. If a little piston slop caused the block to wear out, then diesel engines should wear out every 20,000 miles...

Do Wiseco pistons come with rings?

All Wiseco pistons are forged from high silicon, low expansion aluminum alloy. This offers a superior strength, weight reduction, improved heat transfer and longer life. Wiseco pistons come with 1 piston, ring set, wrist pin, and circlips.

How much HP can cast pistons take?

Stock cast pistons will limit you to 5800rpm, but cast pistons will hold more than 500hp. It is good to 7000 for forged pistons.

Are flat top pistons better?

Now, however, engine builders are leaning towards small combustion chambers with flat-top pistons—or at least pistons with restrained domes—to achieve a higher CR. "Flat-top is the ideal scenario," says D'Agostino. "It's going to be your best burn— most efficient as far as combustion efficiency is concerned.

What are the 3 types of pistons?

There are three types of pistons, each named for its shape: flat top, dome, and dish.

Are OEM pistons cast or forged?

GLM pistons, like OEM pistons, are cast as opposed to forged. We have all heard the advantages of forged pistons. However, when you consider the disadvantages of forged pistons it becomes very clear why GLM cast pistons are the ultimate pistons for your rebuilding and repair projects.

Do aftermarket pistons increase horsepower?

Fourth, a well-designed aftermarket performance piston will free up some additional horsepower by reducing the friction in the cylinder. Many times, the forged pistons will use thinner ring sets and have a skirt profile which dramatically reduces cylinder-to-piston contact.

Do forged pistons need more clearance?

Import Power said: For the most part, a forged piston will call for a larger skirt to wall clearance than a stock cast piston due to growth. Most forged pistons call for 4-5 thou. MUCH looser than stock cast pistons.

What is stronger cast or forged?

Forged parts had a 26% higher tensile strength than the cast parts. This means you can have stronger shackles at a lower part weight. Forged parts have a 37% higher fatigue strength resulting in a factor of six longer fatigue life.

Are forged internals worth it?

Forged parts often start out as castings. In high-horsepower applications and other cases where RPM and/or cylinder pressures (BMEP) are very high, the added expense of forgings is well worth it. BMW, Porsche, Corvette, Ferrari, etc. will use forgings where cost is less of a concern vs. performance and perception.

Why is forging preferred over casting?

Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part. The advantages of forging include: Generally tougher than alternatives. Will handle impact better than castings.

How are forged pistons made?

Regardless of the type of press, pistons are forged using a “backwards extrusion” process where the material from the slug flows back and around the descending punch to form the cup-shaped forging.

What is the highest Compression Ratio for 93 octane?

We are being told by most piston manufacturers that 9.5:1 is the most you should run in an engine with cast iron heads on 93 octane pump gas. Because aluminum conducts (dissipates to the cooling system) heat much faster than cast iron does, you can run 10.5:1 with aluminum heads on 93 octane.

What is the best Compression Ratio?

A higher compression ratio -- say, from 12:1 to 14:1 -- means higher combustion efficiency. Higher compression ratios and combustion efficiency mean more power with less fuel, and fewer exhaust gases.

Does boring an engine increase horsepower?

Boring an engine involves using machines to widen and taper the cylinders. From a performance standpoint, boring an engine could give you more horsepower and torque, as it will change the engine's displacement.
