The CamPro power upgrade was long overdue. KC had already invested thousands of ringgit and countless hours upgrading his CamPro IAFM engine. Now, it was time to see what those bolt-on parts could really do. Instead of turbocharging, KC focused on naturally aspirated (NA) mods. His goal? To gain maximum power without forced induction.
So, he sent his Persona to a dyno tuning shop. There, they fine-tuned the cam pulley and fuel regulator to squeeze out every bit of power. But first, let’s recap what KC installed and how much each part cost.
CamPro Power Upgrade: The Mod List
KC’s CamPro power upgrade focused purely on boosting engine performance with a carefully selected set of plug-and-play parts. Below is the cost breakdown for the modifications. Note that the prices are rounded for reference and may vary depending on your location and bargaining skills.
- K&N Air Filter – RM300
- Full Exhaust System – RM800
- 57mm Throttle Body – RM500
- Adjustable Cam Pulley – RM600
- Fuel Regulator – RM550
- KemKita Hi Camshaft – RM1,850
Total Investment: RM4,600
These upgrades aimed solely at enhancing power output. Other mods like suspension, wheels, or cosmetic changes were not included in the performance budget. Every ringgit spent went into making the CamPro IAFM engine more responsive, efficient, and enjoyable to drive.
Dyno Test: Measuring the CamPro Power Upgrade
The dyno session started with a baseline run — no tuning applied. Surprisingly, the Persona hit 116.02 PS at the wheels, which translates to around 138 HP at the engine. That’s already a 28 HP gain over Proton’s stock 110 HP figure.
Next, the team adjusted the fuel pressure regulator. Torque improved slightly, but peak horsepower remained the same.
Then came the real performance jump — tuning the adjustable cam pulley. After several runs and fine adjustments, the best result came in at:
- 121.61 PS at the wheels
- 149.14 Nm torque
- Estimated 144 HP at the engine
That’s an impressive 34 HP increase without touching the ECU or adding a turbo kit.
Is the CamPro Power Upgrade Worth It?
Some might ask, “Why spend nearly RM5K on NA mods when a cheap turbo kit could give more power?” Fair question. But NA tuning offers more linear power delivery, reliability, and fewer headaches compared to budget turbo kits.
Also, tuning naturally aspirated engines is a different kind of satisfaction. You get smoother revs, cleaner throttle response, and performance that builds with every mod. KC preferred this route and has no regrets.
Final Thoughts
This CamPro power upgrade clearly proves that naturally aspirated (NA) mods can deliver real, measurable gains — 34 extra HP, to be exact. While the process required time, effort, and investment, the results speak for themselves.
With the right combination of parts, careful tuning, and a bit of patience, you can truly unlock the hidden potential of the CamPro IAFM engine. Moreover, unlike budget turbo kits, this NA setup offers a more linear power band, better throttle response, and greater reliability.
So, if you’re planning to follow a similar upgrade path, don’t skip the dyno tuning. It’s a crucial final step to ensure everything works in harmony and delivers the performance gains you’re aiming for. Ultimately, proper tuning can make all the difference between a decent upgrade and a great one.
Thinking of trying this yourself? By all means, go for it — just make sure to tune it right, and you might be surprised by what your NA CamPro can achieve.
