Dernier blog de l'entreprise Precision Engineered VTEC Blockoff Plate Boosts Bseries Performance

In the world of high-performance engines, every detail matters. For B-series engine enthusiasts seeking peak performance and a clean engine bay aesthetic, the stock VTEC system can become a potential bottleneck. The redundant VTEC solenoid not only adds unnecessary weight but also compromises the visual appeal of the engine compartment. SpeedFactory Racing now presents its Billet VTEC Block-Off Plate – the perfect solution to revitalize your engine and unlock unprecedented potential.

Eliminating Redundancy: The Ideal Solution for VTEC Disabling

The SpeedFactory Billet VTEC Block-Off Plate is engineered specifically for performance-driven B-series engines, offering an optimal solution for disabling the VTEC system. Whether you're running locked VTEC camshafts, a single cam configuration, or maintaining dual cams, this block-off plate delivers exceptional performance and reliability. Say goodbye to the bulky factory VTEC solenoid and welcome a new era of lightweight efficiency.

Why Disable VTEC?

For certain modification scenarios, disabling the VTEC system provides several advantages:

  • Simplified Engine Architecture: Removing the VTEC solenoid reduces complexity and potential failure points while improving reliability.
  • Weight Reduction: Eliminating the solenoid reduces overall engine weight, enhancing acceleration and handling.
  • Improved Low-RPM Torque: In some applications, disabling VTEC can optimize low-end torque for better daily driving responsiveness.
  • Enhanced Engine Bay Aesthetics: The removal creates a cleaner, more visually appealing engine compartment favored by modification enthusiasts.

Precision Engineering: The SpeedFactory Quality Commitment

SpeedFactory understands that details make the difference. This VTEC block-off plate is machined from aerospace-grade 6061-T6 aluminum billet using precision CNC processes to ensure flawless execution. Unlike inferior alternatives, SpeedFactory's design maintains perfect compatibility with OEM gaskets for leak-free sealing without compromise.

Aerospace-Grade 6061-T6 Aluminum: The Perfect Balance

6061-T6 aluminum alloy is widely used in aerospace applications for its exceptional strength-to-weight ratio, corrosion resistance, and machinability. SpeedFactory selected this material to ensure reliable performance under demanding conditions.

Precision CNC Machining: Where Details Matter

Computer Numerical Control (CNC) machining enables exacting dimensional accuracy and surface finish. SpeedFactory employs advanced CNC technology to produce block-off plates with perfect fitment and OEM-level quality.

OEM Gasket Compatibility: Leak-Free Assurance

The plate's design ensures perfect compatibility with factory gaskets through precise dimensional control and surface treatment, eliminating potential oil leaks.

Lubrication Upgrade: Beyond Basic Block-Off

The SpeedFactory solution transcends basic sealing functionality with its integrated oil bypass channel that directs lubricant to the rocker arms. This reduces operating temperatures and extends component life, ensuring optimal lubrication even under extreme conditions.

Oil Bypass Channel: Enhanced Rocker Arm Lubrication

The rocker arms – critical components transferring camshaft motion to valves – benefit from additional oil flow during high-load operation, reducing wear and heat-related stress.

Form Meets Function: SpeedFactory Design Philosophy

Featuring black anodized finish for corrosion resistance and understated elegance, the plate bears laser-etched SpeedFactory Racing branding. Optional titanium hardware provides further weight reduction and visual impact.

Black Anodization: Durability Meets Style

The anodized surface treatment enhances corrosion resistance while delivering a premium appearance.

Key Advantages at a Glance

  • Precision CNC-machined 6061-T6 aluminum construction
  • Black anodized finish for durability
  • Integrated oil bypass for enhanced lubrication
  • Laser-etched branding
  • Includes stainless hardware (titanium upgrade available)
  • 0.62 lb weight reduction versus stock VTEC solenoid

Technical Recommendations

For locked VTEC, single cam, or dual cam configurations, SpeedFactory recommends welding shut unused camshaft oil passages and enlarging active oil passages to 0.078" (using a 5/64" drill bit) to optimize lubrication and longevity.

Application Coverage

Compatible with:

  • 1992-1993 Acura Integra GS-R
  • 1994-2001 Acura Integra GS-R & Type R
  • 1999-2000 Honda Civic Si
  • 1994-1997 Honda Del Sol VTEC

Understanding VTEC Systems

Honda's Variable Valve Timing and Lift Electronic Control (VTEC) technology uses multiple cam profiles to optimize engine performance across different RPM ranges. While offering benefits like improved powerband characteristics, the system adds complexity, weight, and potential failure points – factors that make disabling desirable for certain applications.

Installation Considerations

Proper installation requires:

  • Thorough cleaning of mounting surfaces
  • Correct torque application
  • Post-installation leak verification
