GEN 5 Stage 2 Cam w/VVT Limiter

The GEN 5 Stage 2 Cam with VVT Limiter from Brian Tooley Racing represents a significant step up for enthusiasts targeting aggressive camshaft profiles without sacrificing engine reliability. This billet cam is engineered for forced-induction and naturally aspirated applications where variable valve timing control must be constrained to prevent detonation and valve float at elevated boost or RPM levels. Whether you're building a track-focused LS or LT platform or tuning a street engine for maximum mid-range punch, the VVT limiter integration keeps timing events within safe operating windows while the Stage 2 profile delivers noticeable improvements in cylinder filling and scavenging efficiency.

This camshaft employs precision billet construction to ensure dimensional stability and durability under high-lift, high-RPM stress. The Stage 2 profile geometry is optimized for overlap and duration characteristics that favor power band expansion without compromising idle quality or drivability on stock-class throttle bodies. The integrated VVT limiter electronically restricts variable valve timing advance and retard, preventing the PCM from commanding aggressive timing curves that would otherwise induce knock or mechanical damage in high-compression or boosted scenarios. Valve lash and push-rod geometry remain compatible with OEM-style rocker arms, simplifying installation on existing engine platforms and reducing secondary modification costs.

This cam suits builders targeting 500+ horsepower builds on naturally aspirated platforms or those adding moderate boost (8–12 psi) without a complete fuel and ignition overhaul. Installation requires standard cam timing tools and thorough verification of valve-to-piston clearance, especially in engines with aggressive compression or custom piston designs. Tuning adjustments through a quality dyno session are strongly recommended to maximize the profile's potential and ensure all VVT parameters work in concert with your fuel and spark strategy. Compatibility spans most modern LS and LT generation engines equipped with variable valve timing; verify your specific engine code and existing cam specifications before purchase to confirm fitment.
