Mast Motorsports Completes Merger with ENDYN

Nacogdoches, TX – To broaden its portfolio of industry-leading engine components and services, Mast Motorsports has completed a merger with Ft. Worth-based cylinder head and induction specialist ENDYN (Energy Dynamics). In the past, the two companies have worked closely together to co-develop ENDYN’s all-new Honda cylinder heads. By leveraging ENDYN’s 60-plus years of race engine development with Mast Motorsports’ engineering and manufacturing capabilities, this exciting endeavor promises to bring unparalleled performance and quality to Mast’s new Race Cylinder Head Services division. 

As part of the merger, ENDYN will relocate its current Ft. Worth facility to Mast Motorsports’ all-new 22,000 square-foot cylinder head R&D campus in Nacogdoches, TX. ENDYN Founder Larry Widmer will take the reins of Mast’s newly established Race Cylinder Head Services division while continuing to run ENDYN’s day-to-day operations. “This partnership has a world of potential, and I’m very excited to work with everyone at Mast Motorsports,” Widmer stated. 

With a long and decorated history that includes countless achievements in NHRA Pro Stock, NASCAR Cup, IndyCar, Australian V8 Supercars, AHRA Super Stock and CAN-AM, ENDYN has always prioritized on-track performance and durability. Although the company officially opened its doors in 1973, Widmer’s fascination with internal combustion engines dates back to the late-‘50s, when he managed to squeeze 43 horsepower and 21,000 rpm from his 100cc, two-stroke go kart by tweaking the port timing, cross-sectional areas, combustion chamber and piston design.
