Porting & "Polishing"

The pictures you are looking at are all off our R1 race bike which has recently won a National round of the Formula Extreme Championship.

The R1 cylinder is a very time consuming head to improve on as it has 5 valves and the ports are already very good to start with. But with a lot a patience you will be rewarded for the time spent. It is vital not to attack these heads blindly as it will result in big losses every time. Very little material is removed as the job is more about refining than anything else. 

You may also notice that the finished result is not polished. This is because it just doesn't flow as well, or atomize fuel as well. Polished ports may look pretty, but they don't work as well as these ones do.

We have also developed our own port surface to maximise these effects and encourage the charge to swirl as it moves through the port, further increasing both flow and atomization.

Prices for this job start from $995.00 Aust depending on your requirements.
