DEDICATED TO HORSEPOWER THE RAW DIFFERENCE

There are several important reasons why RPI are able to produce such impressive horsepower and torque numbers and be totally reliable at rock bottom prices. Our individualized engine program and daily interaction with our highly skilled engine builders in the USA, together we are on the leading edge of technology and apply everything we learn to produce more powerful and more reliable engines for our customers.

Our production arm in the USA gives RPI greater buying power which means you save $$$$.

All our engines are one-off custom built, machined and blueprinted in the USA by our highly skilled engine technicians, that have many years of winning experience in their field. Every engine is dyno-tested this ensures certified performance and delivery of actual results.

Most crate engines that come out of the USA are exactly that a ‘’Crate Engine’’screwed together on a production line by OE manufactures if you’re lucky. I have machined and assembled many engines over the years and have witnessed firsthand some of the down sides with ordinary crate engines. The problem is this: unless you have x-ray eyes you don't know what’s inside.

Every RPI engine comes complete with a build sheet with ALL specs and clearances documented to the .0001'' and dyno print out with actual results of your engine.

Are you looking for thoroughbred bred Horsepower? Big displacement torque monster?  Well you have come to the right place!

RPI will make all your big horsepower dreams reality from 400-1500+HP 

          Awesome power -certified performance - actual results

Yours Sincerely
Pat Hall
