Power by design

Port technology is one of the secrets to our success. One of the fundamentals to create torque and power is the ability to induct as much high speed air and fuel into the combustion chamber.


with  all Race engines the size of the port is not everything, but the shape and design are. All of our heads are Air Flow Tested to ensure the highest quality is acheived.


We can build most popular Race engines including C20XE ( Red Top), Cosworth YB, Vauxhall  8v - C14se,  Honda, Duratec and many more Race engines and Rally engines

We have invested in the very latest technology in "Dyno" Rolling roads. We can measure upto 600 BHP.


Our bespoke software allows us to create 3D mapping to enhance and smooth out any engine charictaristics.


We can run up your engine and simulate any number of  external influencing environment such as wind or road incline.

We specialise in ECU mapping for all types of race engines. We can use most popular makes of ECU which include DTA, Omex, MBE, Megajolt, Megasquirt and Power commander 3 & V


With almost every rolling road session we will carry out a health check to ensure that your car is safe to tune, we will also offer advice with what we see in our findings and how you can progress in your engines performance and how to get the most out of it.
