Description
Tempo-800 Valvetrain Integration Group
Proven parts you'll probably want to buy together to reach your 800-1000whp goals!
1. GSC Power Division Beehive Springs & Titanium Retainers
[ VALVETRAIN STABILITY: MANDATORY ]
High-lift cams like the S2 profile require harmonic dampening that standard dual-spring setups can’t provide. The GSC Beehive design reduces moving mass, allowing for higher RPM ceilings and preventing "valve float" during aggressive downshifts on the ZF 8HP70.
-
Material Logic: Nano-peened wire for maximum fatigue life.
-
Hardware: Lightweight Ti-64 titanium retainers.
-
Requirement: Mandatory for any build exceeding 7,500 RPM.
-
Verification: Verified for 100psi+ manifold pressure.
2. GSC Power Division S2 Camshafts (2JZ-GTE)
[ SYSTEM STATUS: SPECIFIED ]
The S2 profile is the mandatory valvetrain upgrade for the 800–1000hp power band. Designed to maintain mid-range torque while unlocking high-RPM flow, these are the exact cams used to benchmark the Project Octave blueprint.
-
Logic: 274° / 274° Duration.
-
Peak Power Range: 4,500 – 8,500 RPM.
-
Verification: Optimized for high-boost E85 applications.
-
Requirement: Must be paired with GSC Beehive Valve Springs for harmonic stability.
