Custom Race Engine design and manufacturing

Custom engine design and manufacturing is our main focus at Elmer Racing. Our history is in extreme performance racing engines, as in our full billet #Thor racing engine, with the highest power-to-mass ratio of any OEM circuit racing engine ever! (beating the previous record holder, the Honda V10 F1 engine)
No other manufacturer has a 4 valve billet engine incorporating a full cooling system, that is needed for circuit racing and other long duration engine operation.
We also provide design and manufacturing support to other businesses for both racing and non-racing, series production and prototype/test engines.

Billet design and manufacturing

Billet Elmer Racing merge collectors

Our 304/304L stainless steel merge collectors are the most cost effective and durable options for turbo exhaust manifold manufacturing. So good in fact that they are also being used by customers on naturally aspirated engines! With over 250+ different designs available, we have most of your needs covered. Custom designs can be done also. Check our online RaceShop for some available examples! Other alloys available on request.

Custom Billet components

We regularly help design and manufacture custom, complex shaped components for our customers. Intake manifolds with integrated bellmouths, flanges with built-in transitions, barrel throttle bodies, industry components, and much more!
We're setup to be able to provide these services for a wide range of materials, hardened tool steel, magnesium, aluminum, stainless steel, we even machine wood and plastics for special orders.

Check out our online RaceShop, for some ideas of the kind of custom products we can make!

Design and Optimization

We can do complete vehicle dynamics simulations for Rally and Circuit race cars. To investigate the performance of whole vehicle packages, and how the components perform. FEM, mechanism simulation, CFD, we do it all. These services are also available to select industry sectors.

The Team

The corner stone of Elmer Racing, the Elmgren family, has been active in motorsport since 1993. We have the experience and the equipment/software to do aero optimization, component design and optimization, multi-axis prototype-part milling, as well as vehicle performance and track simulation.

We're used to pushing component design to the limit, minimizing mass and maximizing performance as efficiently as possible!
