Performance Trends Software for Engine Building / Tuning Software & Tools

Performance Trends offers several tools to make your engine building work more accurate, faster, more efficient and more professional.  Some of these tools are software programs only, and some have your computer connected to sensors and possibly actuators.  

For example, In the case of our Port Flow Analyzer with our Automatic Valve Opener installed on a SuperFlow SF1020 bench, you can actually automate the entire flow bench test.  You can start it up and walk away and it will step through each lift, change ranges if necessary, and shut down the bench when it is done.  This can be a huge time saver, and produce more accurate data in the process.

 

Compression Ratio Calculator v2.3 Computer Software to Calculate Compression Ratio, Dynamic Compression Ratio, Cranking Compression, Boring & Stroking Calculations, and Other Common Engine Building Calculations

Port Flow Analyzer v3.5 Computer Software to Record (by hand or electronically), Calculate, Save, Graph, Report and Analyzer Flow Bench Data.  This software also interfaces to our Black Box II or SuperFlow's FlowCom electronics, and our new Valve Opener so you can computerize some or all of your flow bench testing.

Tumble Fixture Swirl and Tumble are 2 different types of motion the air/fuel charge can exhibit as it enters the cylinder on the intake stroke. Generally, swirl is measured on 2 valve engines and tumble is measured on 4 valve engines. However, if you are looking for that extra 0.5% power and want to completely measure differences between different head modifications, you would want to measure both.
