OEM High Performance / Low Quantity Engine design and manufacturing

Proof

5 back-to-back world championships with our first custom OEM racing engine, Thor from 2017. And the highest power-to-mass ratio OEM circuit racing engine ever, 1500hp and 150kg for the complete engine (later updated to 2000hp). Our Hel engine from 2024 represents our newest design and manufacturing capability.

Reliable Production

Very high engine manufacturing reliability is a major benefit of our OEM billet design/manufacturing type. We focus heavily on reducing the amount of process steps, custom tooling, and machines required to manufacture and assemble our engines, resulting in much improved process reliability. Less things to go wrong, and very few moving parts in the manufacturing and assembly process is a huge help in being able to produce top level engines with a lean team.

Fast Design Time

Turn around time for custom OEM engine designs from us is hard to beat. With a efficient and scalable design process, no manufacturing tooling to design and produce, and fast iterations pre- or even in-production, we prototype as we manufacture.

As a added bonus our scalable design and manufacturing process allows us to take on new projects almost regardless of our work load.

Adaptable

50 - 30,000hp power output. 1 to 1,000 engines. Racing, off-shore, hypercars, (non-certified) aviation, restomods, industrial/heavy equipment, unique prototypes or show concepts.
Our billet design and manufacturing process has very few limitations and adapts easily to a variety of engine layouts, and even crazy concepts. Efficiently making billet engine designs is a hard problem, but we have a good solution for it and continue improving with each engine design. Allowing us to take on the hardest engine problems, toughest power / mass ratio performance targets, craziest engine packaging and layout types, and difficult fuel efficiency goals.

Note: Our Elmer Racing billet design and manufacturing process does not lend itself to low cost production. You likely need to have a high capability target, or low engine quantity for us to be able to provide you with the best solution.

Billet Elmer Racing Merge Collectors

The hottest and highest stressed part of your exhaust manifold will almost always be your collector. Welded and cast components can only go so far before it becomes close to impossible to make them last in tougher use or at high use cycles.
This is where our Billet Merge Collectors come in.

Our Elmer Racing stainless steel billet merge collectors withstand even the harshest racing conditions, and provide good street durability as well. These are the best choice for use cases like FIA RallyCross with extreme anti-lag, diesel tractor pulling with EGT's through the roof, and harsh "two step" and load cycles of drag racing where our collectors provide unparalleled durability while maintaining decent cost.

We have over 300 designs with all flanges from t3, t4, t6, single and dual scroll, as well as v-bands in all the popular sizes, as well as pipe sizes. Check out a sample of the collectors on our webshop by clicking the button below!
