Introduction: Campro Adjustable Cam Pulley Solves Low-End Power Dip
Many Campro engine owners love the top-end power. But they often complain about poor low-end torque and sluggish throttle response. Even with Proton’s IAFM system, the problem persists—especially around 2,000 to 3,000 rpm. One effective solution? Installing a Campro Adjustable Cam Pulley. This upgrade fine-tunes the engine timing and improves torque where it’s needed most.
Why Choose a Campro Adjustable Cam Pulley?
The Campro Adjustable Cam Pulley allows users to advance or retard the camshaft timing. This shift directly affects the torque curve across RPMs.
- Advance the cam: Boosts low-end torque and throttle response. Intake valves open sooner.
- Retard the cam: Improves power at higher RPM. Intake valves open later.
Either way, the adjustable pulley offers flexibility to match your driving style. For city driving or stop-and-go traffic, advancing the cam works best.
Installation: How We Fitted the Campro Adjustable Cam Pulley
My friend owns a Proton Persona and was frustrated by the power dip at low RPM. I introduced him to the Works Engineering Campro Adjustable Cam Pulley, and he decided to go for it.
Here’s how we did the install:
- Remove the cam pulley cover – A few bolts and it’s off.
- Loosen the tensioner – This relieves belt pressure.
- Remove the OEM cam pulley – Unbolt it carefully.
- Install the new ACP – Align the arrow to the “A” mark. Each mark equals 2 degrees.
- Reassemble everything – Bolt it up and refit the cover.
We chose to advance the timing by 2 degrees for now—just enough to test the effect without risking detonation.
Test Drive Results: Did the Campro Adjustable Cam Pulley Work?
With the Campro Adjustable Cam Pulley installed and timing advanced, we took the Persona for a spin. Instantly, throttle response improved. My friend noticed quicker engine reaction and smoother acceleration at low RPM. The hesitation between 2K–3K rpm was noticeably reduced.
We haven’t tested high-RPM power yet. But so far, the results are positive. And since the pulley is adjustable, we can fine-tune more later.
What’s Next for This Proton Persona?
This is just the beginning. My friend plans several more upgrades in the near future—intake, exhaust, and possibly ECU tuning. The Campro Adjustable Cam Pulley lays a solid foundation for better driveability and more performance mods ahead.
Final Thoughts
The Campro Adjustable Cam Pulley is a budget-friendly mod that delivers real-world gains. It’s simple to install, reversible, and customizable. If you’re tired of sluggish low-end response in your Campro engine, this upgrade is a smart first step.
