For some auto enthusiasts, the car that rolls off the assembly line isn't up to speed, so to speak. Some drivers love tinkering with their car engines, adding more power or improving fuel efficiency. But what are you going to do when you want to feel a little more rumbling coming from the engine? There are many ways to increase power. But the key is always controlling that power and keeping that power on tap. With that, these are the parts that you need to upgrade for your high horsepower journey.


Performance cams increase the duration and timing of the valve openings during the engine stroke, increase the horsepower and accelerate your car faster. You're going to idle a little rougher with a performance cam, but you're going to get a gorgeous rumble that's desirable for some gearheads, depending on your vehicle.

Most of the camshaft manufacturers offer a wide range of off-the-shelf grinds that have been developed for specific applications. The secret of choosing a cam that delivers the kind of performance you want is to figure out the rpm range where the engine should be most powerful, and then choose a cam that matches the breathing characteristics of the cylinder heads, the intake and exhaust manifolds, the weight and gearing of the vehicle the engine is entering.

Forged Pistons

Performance enthusiasts and custom engineers prefer the use of forged pistons because they are more durable and easily customized to any configuration that is essential for engine tuning. Some engine applications may require a piston crown fly-cut to assist in valve relief, and this can be easily achieved by using a forged piston. The manufacturing techniques used to make the forged piston make it stronger, as more surface area is concentrated on its shape.

The main feature that makes forged pistons excel in high-performance applications is strength and durability. The high silicone content of the cast pistons makes them brittle compared to the forged pistons. Silicon gives lubricancy to the metal and is mixed in an alloy to reduce heat expansion. This is mainly the reason why the cast pistons require careful handling. Mild shock applied to it may cause the material to break down. The forging process compresses the molecules inside the alloy, resulting in a denser surface area compared to the cast piston.

Modifying the engine to produce more power will benefit from the forged piston, as the high tolerance to abuse enables the tuner or engine builder to make incremental adjustments to improve engine performance. Forged pistons are also readily available compared to cast pistons, which are only available in OEM sizes, hindered by the expensive casting process.

Forged Crankshaft | Stroker Crankshafts

The stroker kit increases the displacement of the engine by lengthening the piston stroke. In order to achieve this increase in stroke, motor components modified from OEM parts will be included in the kit. They allow the piston to travel up and down the cylinder further, thanks to the use of a different crankshaft. Journals along the crankshaft lengthen the distance, depending on the severity of the stroke enlargement. The increase in the height of the journal doubles the increase in the length of the stroke. This is due to a relative increase in TDC (top dead center) and BDC (bottom dead center).

A stroker kit is a relatively complex modification intended only for the most practical of petrolheads. The ability to disassemble the engine, replace the key components, and then reassemble everything is not for the faintness of the heart, but the power gains associated with the stroker kit are well respected in the muscle car world. So, if you have the mechanical knowledge and hardware to do that, a stroker kit can be the key to an additional horsepower.
