Whipple WK-1213-30-NFT - 3.0L 2021-24 GM SUV L87 Supercharger - No Flash Tool

Description

Few full-size SUV upgrades change the driving experience like a properly engineered twin-screw supercharger system. The added low-end torque, sharper throttle response, and stronger pull through the RPM range completely transform how a large SUV feels whether it is used for daily driving, towing, or hauling passengers and cargo. That is exactly what the Whipple Gen 6 3.0L supercharger system delivers for GM's 2021–2026 6.2L L87 Global B SUV platform (Chevrolet Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade). Whipple Superchargers has led the twin-screw industry since 1987, bringing that extensive racing and OEM-level engineering heritage into a direct bolt-on, 50-state legal forced induction package.

At the heart of the system is the Gen 6 3.0L (W185FF) twin-screw compressor, engineered with an integrated casting to eliminate leak paths, reduce adapters, and optimize underhood space. Capable of producing up to 685 horsepower and 655 lb-ft of torque on 93-octane fuel, it utilizes an integrated Crusher™ 112mm venturi-shaped round inlet, a high-flow Whipple air inlet duct, and a supplied GM LT4 3-bar TMAP sensor. Thermal management is handled by a top-mount, discharge-down layout featuring a massive air-to-water aluminum bar-and-plate intercooler core, an oversized dual-pass heat exchanger, an intercooler reservoir, and a high-flow intercooler water pump. Designed for stock, well-maintained engines running 91+ octane premium fuel, this complete system delivers flat, linear torque curves, instant boost response at the hit of the throttle, and proven Global B calibration support.

Features & Technical Highlights:

• Up to 685 HP & 655 lb-ft Torque: Substantial bolt-on power gains that transform acceleration, passing power, and heavy towing capability across the entire RPM range.
• Gen 6 3.0L Twin-Screw Compressor: Features Whipple’s latest rotor profile and close-tolerance internal geometry, delivering maximum boost at the initial hit with reduced drive power consumption.
• Top-Mount Discharge-Down Layout: Directs compressed air downward through the intercooler core, reducing pressure loss, improving thermal efficiency, and maintaining cooler overall operation compared to inverted designs.
• Integrated Crusher™ 112mm Inlet: Outflows smaller 90mm and 93mm inlets found on competing positive displacement blowers, minimizing rotor cavitation and accommodating optional 102mm throttle bodies.
• Patented Intercooled Bypass System: Built-in air-bypass valve recirculates cooled air off-boost to virtually eliminate burst-knock while enhancing highway fuel economy.
• Massive Low-Temperature Cooling Circuit: Combines an oversized front-mount heat exchanger, high-flow water pump, dedicated reservoir, and large bar-and-plate intercooler core for consistent intake charge temperatures.
• Global B Electronic Integration: Supplied with an LT4 3-bar TMAP sensor and engineered to interface with modern GM Global B engine management via validated calibration support.
• OEM-Level Fitment & Quick Servicing: Features factory-style quick-connect coolant fittings, works with the stock airbox and MAF, and allows rapid 3-minute supercharger pulley swaps.
• 50-State Street Legal: Certified under California Air Resources Board Executive Order #D-231-146 for legal highway operation in all 50 states.
