Porting / Portwork
The theory behind portwork in general is not to 'hog' out a part, but do it in a way that promotes more performance, adds more velocity, and improves the efficiency of the part. Sometimes this can be achieved with a simple smoothing of the casting flash, but more often than not, there is some shaping that has to take place in order to get optimal performance from the part.
Many ask, "Why don't they do it from the factory?" It's all about time and cost. Most engines are assembled with conservative tolerances (on all non-critical parts such as manifolds and head ports) and they don't take the time and money to port match each component as the machinery and time is too much to make it cost effective. That's where FFP porting comes in. Closer tolerances and ideal shaping will yield improved flow and increased efficiency and will make the engine breathe easier, thus making it capable of producing more power.
For the most part, any cast metal part can benefit from portwork. Throttle bodies (mostly bored instead of ported), spacers, intake manifolds, heads, exhaust manifolds, headers, turbos/superchargers, and intake/exhaust plumbing in general, all can benefit from porting and coatings.
We have seen improvements of up to 45whp from porting intake manifolds, up to 52whp gains from porting turbo manifolds, up to 15whp from throttle bodies, and "much more" from headwork! Each vehicle is different, but you can see how portwork can be a key component to achieving your horsepower goals.
When you combine your head portwork with our upgraded valvetrain components, or combine a ported intake manifold with our advanced ceramic coatings, you will have the utmost performance available.
