FSAE Performance Valve Train System
In support of the Society of Automotive Engineers’ Formula SAE competition, Del West has recently developed a complete
Performance Valve Train (PVT) system for the most popularly used engines, and offers these systems to qualified buyers at
special, discounted prices.
Currently available for the Honda, Yamaha, and Suzuki 600 cc engines, the Del West PVT package includes forged titanium
intake and exhaust valves with chrome nitride (CrN) coating, lightweight locks and retainers, manganese-bronze valve guides,
and beryllium-copper (BeCu) valve seat inserts.
To qualify for the special Formula SAE system pricing, orders must be placed via an accredited University purchase order,
and are limited to a maximum of two (2) engine sets per calendar year.
Contact the Del West engineering or sales staff for additional details. Included with each PVT system is a comprehensive
technical guide as wel as SolidWorks component CAD files.
