For most of the street strip engine combinations, off-the-shelf pistons work greatly. Custom pistons are the only option to push the performance for engines that use a combination of low-volume components. Many people doubt how to . So here we are with some of the important tips you should consider while ordering a custom piston.
1. Evaluate your needs and purpose –
Before ordering a custom piston, determine why you need it. Whether the aim is to increase the quality, diminish the weight, or oblige a stroker crankshaft. Don’t just make assumptions about compression ratio, bore size, etc. Be accurate while providing the information. These days aluminum pistons that are manufactured exclusively are CNC machined.
2. Fill out the requirements sheet carefully –
Most piston developers provide their clients with the datasheet to fulfill their needs while placing the order. If possible, you can approach the manufacturer; else, it is provided on their website. Try to fill all the data with genuine figures. As soon as you finish with this task, it is given to the cylinder maker to start your request.
While sending the sheet, try to contact the organization and make the information provided in the sheet more clearly through your words. It will help them understand your requirements in a more precise way. You can even query the specifications you didn’t understand while filling in the data and then fill them in. It will enensure that the cylinder is produced efficiently and effectively per your needs only.
3. Do not make assumptions –
Making estimates and providing wrong information will end up in chaos. You may spend more afterward on a new piston. Time will also be wasted if, at a later stage, you will realize that the information you provided will not work. Hence, it is better to take the measurements rather than make assumptions. Confirm every segment! Don’t let your laziness initially become a headache for you later.
4. Decide power goals –
Make it very clear; the cost and quality of the piston are directly proportional to each other. The higher the rate you want, the more expensive it will be. So, before ordering unthinkingly, determine your budget and the number of pistons you require. If you wish for the cylinder to hold more power, it will be costly too! When the budget is your primary concern, looking for a brand that produces pistons at reasonable prices and fulfills your requirements is recommended.
5. Determine bore size and compression ratio –
Once the amount of power for the efficient working of the piston is finalized, decide the compression ratio and bore size. Generally, low compression for supercharged applications and high pressure for all-engine NA applications is recommended. Bore size can range between 0.5mm to 1.0mm.
