Offering the lowest moment of inertia and the best quality of components in the industry, the Quarter Master 7.25" Steel V-Drive Bellhousing Kits ensure that both acceleration and deceleration are improved, while still giving you maximum driveline durability and rules legality. These lightweight kits combine state-of-the-art engineering and years of racing expertise to give you the perfect combination of quality and value.
These premium kits feature a lightweight CNC-machined steel bellhousing (18 lbs.) that ensures proper concentricity for reduced driveline wear, an ultra light flexplate that reduces the moment of inertia and a 2 or 3-disc V-drive clutch with a balanced button flywheel. The 7.25" V-drive multi-disc clutch offers better cooling, allows clutch dust to easily escape the unit and lowers the moment of inertia. The balanced button flywheel is the best complement to the ultra-light flexplate, as it provides the lightest clutch for your performance dollar.
The CNC-machined lightweight steel bellhousing accepts Quarter Master Tri-Lite or Floating Hydraulic Throw-Out Bearings to increase concentricity and parallelism. With features that significantly improve throttle response and deceleration, along with advanced Quarter Master engineering and manufacturing techniques, this kit a “must have” investment for the Chevy crate racer.
Designed for heavy-duty strength against the stresses of higher horsepower applications, this kit features premium-grade Alto Red Eagle friction clutches and Kolene-treated steel clutches. The Alto Red Eagle friction clutches increase the “holding force” or coefficient of friction, an empirical property of contacting materials, while the Kolene-treated steel clutches disperse heat equally among the frictions and steels. This combination of clutches provides higher performance and durability under higher horsepower applications, and the cohesive lining allows the transmission a better chance of longevity. One final feature is the Kevlar overdrive band to improve the “apply and release” functions while reducing wear.
This master overhaul kit is ideal for any high performance street or all-out racing application that aims to match the stresses of high horsepower engines with bullet-proof drivetrain durability.
Professional Products has expanded the capabilities of their “adaptive learning” Powerjection III EFI system to provide full control of your timing through all load, boost and rpm ranges. MAP based spark control is accomplished with the Powerfire II 2-wire magnetic pickup distributor. This timing control feature, plus the built-in 2.5 BAR MAP sensor, makes the POWERJECTION+PLUS EFI the perfect addition to your supercharged, turbocharged or normally aspirated engine up to 500 horsepower. POWERJECTION+PLUS will work with any brand 2-wire electronic distributor and is available with or without the Powerfire II distributor.
The POWERJECTION+PLUS system features on-board wide-band O2, 2.5 BAR MAP sensor (up to 25psi), 21 x 7 timing control, “adaptive learning” technology which allows the computer to learn as you drive, is laptop compatible (comes with software) and includes FuelOnDemand, which provides complete fuel pump pressure control. POWERJECTION+PLUS contains ALL the features found in high-end box and harness systems without the installation complexity and ugly wiring harnesses.
The system includes a 750-CFM Throttle Body, four 62-lb./hr port style injectors, dashboard software, all wiring and connectors, idle air control, 2.5 BAR MAP sensor, coolant temp sensor, throttle position sensor, wide-band O2 sensor, O2 sensor bung and clamps, fuel inlet kit and 220 L/H fuel pump. All POWERJECTION+PLUS systems are assembled in the USA and are pre-run on an engine dyno prior to shipment.
