Vance & Hines Launches New Four-Valve Suzuki Racing Engine
Racing Applications include Pro Stock, Pro Mod and Pro Street Classes https://vanceandhines.com/ February 1, 2021 – Santa Fe Springs CA – Vance & Hines today launched the company’s long-expected four-valve motor for Suzuki GS-based drag racers. The new powerplant will debut at the NHRA Gator Nationals in Gainesville FL in mid- March. Several teams will be competing with the new Suzuki-based motor and a new Vance & Hines-designed chassis at that event. “The scale of this launch is unprecedented in the drag racing world and it highlights our company’s technical capabilities,” said Vance & Hines President Mike Kennedy. “This engine and the cylinder head design are applicable to several racing classes and easily adaptable to every team that is currently running a two-valve Suzuki GS.

For the first time, Vance & Hines has integrated finger follower technology rather than a shim-under-bucket design in a drag racing cylinder head, which allows for less mass in the valve train and increased RPM. The intake and exhaust port spigots are modular, so they can be adapted to different air boxes and exhaust pipes without redesigning or remanufacturing the head itself. This allows the new head to be used not only in NHRA’s Pro Stock Motorcycle class, but also in the Pro Mod and Pro Street classes. Design credit for the motor, code named “VHIL18504V,” goes to six-time NHRA champion Andrew Hines. The head was completely developed in Solid Works CAD design and was a fully functional running model […]
