How Much Horsepower Does a Stage 2 Cam Add?

Thinking about upgrading your engine with a stage 2 camshaft? You're in the right place! This guide will delve into the horsepower gains you can expect, the factors influencing those gains, and what you should consider before making this performance modification.

Understanding Stage 2 Camshafts

Before we dive into horsepower figures, let's clarify what a stage 2 cam is. Camshafts control the timing of your engine's valves, influencing how much air and fuel enter the cylinders. A "stage" refers to the cam's aggressiveness; a stage 2 cam represents a significant upgrade over the factory cam, offering more aggressive valve timing and lift. This translates to improved airflow and, consequently, more power.

The Variable World of Horsepower Gains

It's impossible to give a single, definitive answer to "how much horsepower does a stage 2 cam add?". The increase varies dramatically depending on several key factors:

• Engine type and displacement: A stage 2 cam in a small, naturally aspirated engine will yield different results than the same cam in a larger, forced-induction engine. Larger engines typically see proportionally larger gains.
• Supporting modifications: A stage 2 cam is rarely an isolated upgrade. Other modifications such as headers, exhaust systems, cold air intakes, and ECU tuning significantly impact the overall horsepower increase. Without these supporting mods, the cam's potential may be limited.
• Cam specifications: Stage 2 cams themselves vary widely. Different duration, lift, and lobe separation angles result in varying horsepower and torque curves.
• Installation and tuning: Proper installation and professional tuning are critical. An improperly installed or tuned cam can actually reduce horsepower or even cause engine damage.

Expected Horsepower Increase Ranges

While precise numbers are elusive, you can generally expect a stage 2 cam to add anywhere from 15 to 50 horsepower to your engine. This is a broad range, and the actual gain will fall within it based on the factors listed above. Consider the lower end of this range (15-20 hp) if you're only installing the cam. To reach the higher end (30-50 hp), you'll likely need a comprehensive set of supporting modifications and professional tuning.

Beyond Horsepower: Torque and Drivability

It's crucial to understand that a stage 2 cam doesn't just increase horsepower. It will also affect your engine's torque curve. This means you'll likely experience changes in drivability. You might notice improvements in acceleration, but the cam could also shift the powerband, making the engine feel less responsive at lower RPMs. This is especially true without proper tuning.

Considering the Investment

A stage 2 camshaft is a significant modification that requires careful planning. Factor in the cost of the cam itself, installation, necessary supporting modifications, and professional tuning. Weigh the potential gains against the investment, ensuring it aligns with your performance goals and budget.

Consult a Professional

Before installing any performance modification, including a stage 2 cam, it's highly recommended that you consult with a reputable engine builder or performance shop. They can assess your specific vehicle and recommend the most suitable cam and supporting modifications for optimal results and to avoid potential problems.
