The saying “Build a better mousetrap, and the world will beat a path to your door” is often attributed to poet and philosopher Ralph Waldo Emerson. While his original wording was more eloquent, the modern version still conveys the idea. The challenge is to find ways to improve existing products, and enhancing hot rod parts is exactly what Vintage Air achieved with the Front Runner accessory drive system.
Vintage Air’s billet front accessory drive system for small- and big-block Chevys includes brackets, pulleys, water pump, high-amp alternator, A/C compressor, and drive belt—power steering pumps are optional.
Mounting engine-driven accessories in a hot rod has always been a challenge, both in size and strength. Getting components tightly packed against the engine to fit into a small engine bay was tough. Designing brackets that were sturdy enough to prevent vibration, look clean, and properly align all the pulleys was also difficult. All those issues disappeared when Vintage Air introduced the Front Runner, their smallest drive package ever, offering a better solution for these problems.
As Vintage Air’s Rick Love explains: “We introduced the first Front Runner drive system (small-block Chevy) in late 1999. We trademarked the name as well. The criteria were to design and develop a robust and rigid platform that mounted strictly to the engine block so that deck height, head, and intake manifold choices were irrelevant.” By securely mounting all engine-driven components to a rigid platform, it was no longer necessary to pivot them to properly tension the required V-belt array. Instead, a serpentine belt is used with a spring-loaded tensioner, which eliminates the need for belt adjustments. Additionally, serpentine belts save space and can handle more tension to prevent slipping without stretching. Today, many modern engines, such as the GM LS Series and the Ford Coyote modular engines, require the integrated mounting approach that a Front Runner provides.
The included high-flow, reverse-rotation Stewart water pump features 3/4-inch ball/roller bearings that provide five times the strength of standard bearings. The precision-ground fan hub ensures perfect pulley alignment.
Included in the small-block Chevy Front Runner kit, we installed a Stewart water pump. These high-flow, reverse-rotation pumps are unique because they feature dimensionally accurate mounting surfaces (the depth of the holes that attach the pump to the block). This allows for perfect alignment of the Vintage Air main bracket and pulley, something that can’t be guaranteed with OEM water pumps.
The Front Runner kit includes a Mechman “hairpin” (Denso design) high-output alternator with a 170-amp output (130-plus at idle). It comes with a heavy four-gauge charge wire, wiring kit with terminals, and a crimping die. These Vintage Air alternators use an ignition switch-activated wire to excite the alternator, as this method offers better load response than one-wire versions. While 170 amps should be enough for most applications, Vintage Air now provides a 320-amp alternator for extreme electrical demands. Regardless of the alternator selected, a ground wire from the lower alternator mounting bolt to the engine block is highly recommended.
Our Front Runner was equipped with the standard alternator. Although it’s rated at over 130 amps at idle and more than 170 amps at cruise rpm, the test tag shows the actual output is higher.
It is logical that the Vintage Air Front Runner would include an A/C compressor. Front Runner kits feature a compact A/C compressor that uses R-134a refrigerant and comes with a bolt-on, O-ring compressor block. Placing the connections on the side of the compressor makes connecting the refrigerant lines easier.
As Brennan’s C3 Vette has been updated with a Detroit Speed & Engineering (DSE) front suspension system with rack-and-pinion steering, a power steering pump is required. Vintage Air’s GM TC power steering pump (often referred to as a Type II), included with the Front Runner, supplies the 1,800-psi peak pressure and 3-gal/min flow that the DSE rack requires. This pump is also appropriate for conventional GM power steering boxes.
Included with the Front Runner kit is a power steering pump with a flow rate of 3.0 to 3.4 gal/min. For early Mustang II rack-and-pinion applications, a lower flow-rate control valve (PN 8520010) is available.
Vintage Air offers Front Runners in various finishes. Brackets are available in machined or black anodized options. Compressors and alternators come in natural, polished, or chrome finishes. Pulleys, clutch, and tensioner covers are offered in chrome or black anodized. All kits include ARP fasteners.
Currently, Front Runner kits are available for small- and big-block Chevrolets, as well as GM LS, LS7, LT1, and LT2 engines. Additionally, Vintage Air recently introduced cast-aluminum Front Runner kits for LT1 and LS engines. And Vintage Air hasn’t forgotten about Ford enthusiasts—Front Runner kits are available for Ford small-blocks and Coyotes. These kits are compatible with most Coyote generations, though some may require a timing cover change.
Vintage Air Front Runner systems are not only compact and sleek in appearance but also more efficient than V-belt-driven systems. Thanks to their thoughtful design and high-quality control, Front Runners are easy to install and virtually maintenance-free. Emmerson may not have been a hot rodder, but he had the right idea. MR
