Factory manufactured cylinder heads do not always perform as well as they could due to manufacturing restraints. A common process performed to modify the ports is called cylinder head porting. This process is essential in getting the most efficient amount and quality of air flow to the intake and outtake ports. By porting the cylinder heads, you allow the engine to perform at peak efficiency. The process is considered one of the most important factors in producing high power output from modern engines. Cylinder head porting can be used to enhance the performance of a standard racing engine or applied to a factory engine to increase power and performance.
The process is not one that is easy or without complications and is often best suited for a professional who provides cylinder head porting service. People trained and experienced in cylinder head porting have the skill and knowledge to achieve the desired results. With that in mind, there are still many people who prefer to work on their own vehicle. This may be due to budget restrictions or simply a desire to have the hands-on experience. For those who decline the use of a cylinder head porting service, there are a few common pitfalls in the porting process which should be avoided. Here are a few tips to ensure these pitfalls are not the downfall of your DIY project.
Be prepared- There is no point in starting the process unless and until you have all the necessary tools to do so. This includes the right cutting tools as well as the safety equipment needed to avoid injury. Flying metal and dust particles require at minimum- a good pair of safety glasses as well as a mask to filter out particles in the air. Have a shop vac handy to clean up your work area as you go, this can also be used to clear debris from the ports as you work.
Don’t rush the process- Depending on what material you are working with, the process can take a good 8-12 hours of time. That is of course if you are working with all the recommended tools and are able to fully concentrate on the job at hand during that time. Remember that when working with cast iron you will need more cutting time than aluminum.
Do your research before you start- New projects often require a bit of trial and error, however you do not want to begin this process blind. Research the products you are working with and the correct process used to reach your end goal. Having a well thought out plan of attack before strapping on the safety glasses will surely increase the likelihood of a positive outcome.
Know when to seek help- With the proper research and tools there is a good chance that you will be able to pull off the porting process on your own, however it is wise to know when to accept defeat. If you continue moving forward on a downhill project it will just end up costing you more money and time in the end. Be reasonable and do not allow your pride to get in the way of seeking professional help from a cylinder head porting service should you notice you are not getting the intended results.
