The Kelford C K20 cam specs VTEC killer cams have been generating buzz in the car tuning world for their potential to deliver jaw-dropping performance gains. Enthusiasts and professional tuners alike have praised their design for pushing Honda’s K-series engines to new heights. But what exactly makes the Kelford C K20 cams so special, and are they the right upgrade for your performance goals?
Whether you’re building a track-focused rocket, a street racer, or a show car with serious horsepower credentials, this detailed guide will walk you through everything you need to know about Kelford’s C K20 cam specs and their unique ‘VTEC Killer’ functionality.
What Are Kelford C K20 Cam Specs?
Kelford C K20 cam specs are aggressive, high-performance aftermarket camshafts designed specifically for Honda’s legendary K20 engines. Renowned for their advanced engineering and precise tolerances, these cams cater to enthusiasts who want maximum performance out of naturally aspirated or high-revving turbocharged setups.
The defining feature of these cams is their ‘VTEC Killer’ design. Unlike typical K-series cams that rely on Honda’s Variable Valve Timing and Lift Electronic Control (VTEC) to enhance performance at different RPM ranges, VTEC Killer cams eliminate this variable system entirely. Instead, they favor high-lift cam profiles designed for full-time, high-performance operation.
Key specifications for the Kelford C K20 camshaft include:
- High-lift design: Maximized intake and exhaust valve lift for better airflow and combustion.
- Precision engineering: Built to handle high RPMs with ease, making them ideal for track or drag performance setups.
- Compatibility: Designed to work seamlessly in K20A, K20Z, and other series engines (with necessary tuning and upgrades).
If you’re serious about improving power output and consistency in high-RPM scenarios, the Kelford C K20 cam and its specifications deserve your attention.
What Are ‘VTEC Killer’ Cams and Why Choose Them?
To understand VTEC Killer cams, we need to revisit how Honda’s VTEC system works. The VTEC mechanism adjusts valve timing and lift based on engine RPM to balance low-end drivability with high-RPM performance. Honda’s engineers designed it for versatility, rather than just outright power.
VTEC Killer cams, like the Kelford C K20, strip away this dual-purpose functionality. By eliminating VTEC entirely, these cams adopt an aggressive, single-profile camshaft tuned for high RPMs.
Performance Benefits of VTEC Killer Cams:
- Power-focused design: VTEC Killer cams target peak performance, often at the expense of low-end versatility.
- Simplified mechanics: Removing VTEC reduces complexity, offering more consistent results at the top end.
- Ideal for racing: Designed for high-revving, track-dominating use, they’re perfect for anyone chasing serious horsepower gains.
While VTEC Killer cams aren’t for everyone—daily drivers might find the low-end loss impractical—they are a dream for those seeking optimal high-RPM performance.
Kelford C K20 Cams vs. Stock and Other Aftermarket Options
How do the Kelford C K20 cam specs stack up against the competition? To answer this question, we’ll compare them to stock K20 cams and similar aftermarket offerings.
Stock K20 Cams
- Performance: K20’s stock cams are versatile, balancing a smooth idle with reasonable high-RPM power. Ideal for daily driving.
- Limitations: They lack the aggressive lift and timing required for serious track performance.
Aftermarket Performance Cams
- Mild Cams: Balanced designs such as Skunk2 Stage 1 cams maintain some low-RPM drivability while boosting performance.
- Aggressive Cams: Kelford, Skunk2, and Brian Crower offer high-lift profiles—but few deliver the same consistency in extreme RPM ranges as the Kelford C K20 cams.
Why Choose Kelford C K20 Cams?
- Superior high-RPM performance: Their VTEC Killer design shines on the track or dyno, especially in turbo builds.
- Proven results: Backed by extensive dyno testing and real-world feedback from racers worldwide.
Real-World Reviews and Dyno Testing
Kelford C K20 cams have earned a stellar reputation among enthusiasts and professionals alike. Here’s what the data—and drivers—say about their performance.

- “If you’re building a track car, just get these cams. The dyno numbers don’t lie, and the consistency at high RPMs is unmatched.”
Installation and Tuning Tips
Upgrading to Kelford C K20 cam specs vtec killer isn’t as simple as swapping parts—you’ll need proper installation, supporting components, and advanced tuning to get the most from them.
Installation Checklist:
- Upgraded valvetrain components (e.g., valves, springs, retainers) to handle increased lift and RPM.
- Stronger head gaskets and ARP head studs (recommended for boosted builds).
- Precision timing tools to ensure proper cam alignment.
Tuning Recommendations:
- Professional tuning is a must after installation. Your tuner should adjust fueling, ignition timing, and cam phasing for maximum results.
- Dyno testing during tuning ensures maximum power without compromising reliability.
Pro Tip: Pairing Kelford C K20 cams with high-compression pistons or forced induction can dramatically improve performance. Always consult a professional builder when selecting components.
