For automotive enthusiasts seeking to extract maximum power from their Gen 5 LT1 engine, the Texas Speed & Performance (TSP) 6.2L LT1 “EL-C7” V2 camshaft stands out as a premier upgrade. This Stage 3 LT1 cam is meticulously engineered for those who demand aggressive performance and are ready to modify their vehicle to achieve it. Prepare for a noticeable idle lope and substantial power gains with this high-performance camshaft.
Key Features of the EL-C7 V2 Camshaft
This robust camshaft is designed with specific performance metrics to maximize your LT1 engine’s potential:
- Stage 3 Performance: As a Stage 3 cam, the EL-C7 V2 is built for significant power increases, targeting enthusiasts who prioritize high-end performance.
- Aggressive Cam Specs: Featuring 231/245 duration and .645″/.631″ lift, with a 112 LSA and 109 ICL, this cam is engineered for a powerful top-end rush.
- High Fuel Lobe: Equipped with a +32% fuel lobe, ensuring adequate fuel delivery to support the increased demands of high-performance applications. Note: Lash cap required for installation and is not compatible with LT4 fuel pumps.
- DOD/AFM Delete Required: The EL-C7 V2 camshaft is designed for maximum performance and does not support Active Fuel Management (AFM) or Displacement on Demand (DOD). A DOD/AFM delete kit is necessary for installation.
- VVT Lockout Recommended: For optimal performance and tuning stability, TSP recommends locking out the Variable Valve Timing (VVT) system using a phaser lockout kit with all of their LT series camshafts.
Performance Gains and Engine Compatibility
The EL-C7 cam is specifically tailored for the 6.2L LT1 engine and is optimized to work with a stock compression ratio. When installed, dyno testing has shown impressive gains:
- Power Increase: Expect to see gains of around 107 horsepower and 11 lb-ft of torque.
- Total Output: These upgrades can push your engine to an impressive 598HP and 516TQ.
- Operating RPM Range: The optimal performance range for this camshaft is between 3000-7000 RPM, highlighting its focus on mid-to-high-end power.
Installation and Supporting Modifications
To properly utilize the EL-C7 V2 camshaft and ensure engine reliability and performance, several supporting modifications are recommended:
- Valve Springs: Upgraded valve springs are crucial. Texas Speed & Performance recommends Manton conical valve springs or their own dual .660 spring kit to handle the aggressive valve lift.
- Stall Converter: For automatic transmissions, a high stall torque converter with a 3200+ RPM stall speed is necessary to match the camshaft’s power band and ensure optimal vehicle launch and drivability.
- Phaser Lockout: As mentioned, a phaser lockout kit is highly recommended to maximize tuning potential and simplify the VVT system management.
Drivability and Intended Use
While the power gains are substantial, it’s important to understand the drivability characteristics of a vehicle equipped with the EL-C7 cam:
- Not Ideal for Daily Driving: Due to its aggressive nature and high RPM power band, this camshaft is not ideally suited for daily driving in stop-and-go traffic.
- Weekend Warrior: The EL-C7 V2 is perfect for a “weekend warrior” vehicle – cars intended for spirited street driving, drag racing, and performance events.
- Professional Tuning Required: Adequate and professional tuning is essential to optimize drivability and engine performance with this camshaft. While street driving is possible, it requires careful tuning to manage the aggressive cam profile at lower RPMs.
Texas Speed & Performance rigorously dyno tests all of their LT1 camshaft designs on a SuperFlow 902 engine dyno using a stock 6.2L LT1 engine. This comprehensive testing process ensures that each camshaft, including the EL-C7 V2, delivers a superior power curve without compromising overall performance or engine safety. By thoroughly testing their products before release, TSP provides customers with proven performance and peace of mind, guaranteeing a camshaft that is both powerful and reliable, free from piston-to-valve clearance concerns. When you choose the TSP EL-C7 cam, you’re investing in proven performance and expert engineering.
