The Engine Masters Challenge is a competition built around a single measure: power on the dyno. Top engine builders from across the country bring their combinations to the University of Northwestern Ohio's Applied Technologies College, where each entry is scored on overall output. No style points. No subjective judging. Results only.

Speedmaster has joined as a sponsor of the competition - an alignment that reflects the company's investment in precision engine building and the community of builders pushing what is possible with domestic V8 platforms.

The Format

The 2016 competition marked the second year with a multi-class structure, with refinements carried over from 2015. Regardless of class, each competitor must complete three scored runs within a 35-minute window.

Competition Classes

Small-Block

Domestic pushrod V8s with a minimum displacement of 350 ci using commercially available two-valve cylinder heads.

Spec Big-Block

Designed around easily duplicated combinations, this class requires competitors to select an Edelbrock cylinder head and intake from a list of approved part numbers, paired with an MSD ignition.

Vintage

Open to domestic V8s introduced before 1954, with the exception of Ford Y-Block, MEL V8, Buick Nailhead, Packard V8, and 1956-1967 Chrysler A-Series Polyspheric small-block. Inline-six engines introduced before 1964 are also eligible.

Nitrous

Carbureted, domestic, two-valve V8 engines with a displacement cap of 367 ci. No correction factor for displacement. Each competitor receives the same nitrous jet - fuel jetting is the variable.

Why It Matters

The Engine Masters Challenge represents the intersection of engineering knowledge and applied execution - the kind of environment where Speedmaster's approach to performance is most at home. Supporting this competition is a direct investment in the builders, the craft, and the future of measured performance.
