Once the bottom end is strengthened we start adding some serious horsepower through the cylinder heads. By porting your cylinder head and upgrading valves, stems and springs we can create some big power increases. Using bigger intake runners will create more top end power as opposed to shorter stems that add low end torque. These modifications need to be customised to each engine to avoid things like valve clearance issues. We have built a range of reliable, high horsepower aspirated, turbo and supercharged 4, 6 and 8 cylinder engines, so speak to our technicians and have them design an engine package to suit your needs.
