about us 2

Whether it’s rebuilding a stock engine or developing high performance, we believe that your engine should not only perform the best, it should look the best. We spend much time in presentation, so that you will feel proud of your investment.

Welcome to our website. Please look through the various sub categories where you can find previous and current builds, along with many of the parts and services we offer.

Thank you and remember,

As Benjamin Franklin once said,

“The bitterness of poor quality remains long after the sweetness of low price is forgotten”

Performance Developments urges owners of cars of any level of performance to “take it to the track.”

Do not street race.

Performance Developments is involved in the development of high performance engines. These engines are designed for track use, where high performance driving is the safest place to be conducted. Street racing is dangerous for yourself and others. The next time someone pulls up beside you and motions, “do you want to race?”, just wave hello and go about your day without finding the need to race.

There are two components to driving fast. The driver and the car. The driver always must be the fastest. Not the car. When the car becomes the faster of the two, accidents happened. The driver runs out of talent and becomes a passenger in an out of control car.

Thank you for your interest in Performance Developments. We make one of a kind, custom engine parts designed specifically for your needs. We offer special, bespoke engines unlike any other tuner offers. With Neil’s background in Formula 1 you are guaranteed a superior, race quality engine. We offer many upgrade options.  Please let us know exactly what you are interested in and we will gladly give you more information, including a quote for upgrade costs. We look forward to working with you in the near future.
