RayMac Racing builds high quality, dependable racing engines for all types of competitive motorsports. The quality of our work is unmatched, with every attention to detail followed through to ensure you obtain the absolute best in HP production. Every engine we build is blue printed, hand assembled, and dyno tuned using our state of the art SF-901 Engine Dyno. We have the experience to design your engine and components to specifically meet your needs. We design many of the pistons and camshafts we use in our engines to achieve the highest level of HP. These parts are then manufactured for us specifically by companies like Comp Cams, JE Pistons, Manley, Wiseco, and many others. Our emphasis is each part in your engine being as efficient and cost effective for your specific racing application.

We currently have customers competing in most of the major sanctioning organizations including, Nascar, N.H.R.A, I.H.R.A., World of Outlaws, Outlaw Pro Stock, Pro Mod, SCCA, Time Attack, and many others. Our many years of experience designing, building and dyno testing all types of racing engines has taught us how to achieve maximum horsepower with unequaled reliability. We are experts in building and tuning single and dual carbureted gasoline engines, turbo charging, nitrous oxide injection, alcohol injection, alcohol carburetion, tuned port injection, and most other forms of fuel systems.
