  1. Good stuff. Compression test is only good for roughly comparing identical engines or the same engine at different times. It can be used as a crude indicator of engine damage. A Leak down tester is much more useful, more accurate and more specific than a compression test.

  2. So when someone says that if you have a rs468 cam or a 30//30 or a 475 cam you can’t do 11-1 or 12 compression ratio. Your saying that you can it’s all in the tuner? And how he tunes? Great vid by the way

  3. People, if you are building an engine, you need to be aware of the dynamic compression (IMO) which will require a pressure gauge and engine math (which a calculator will be very helpful). Get it wrong and engine life will be very short – detonation kills engines. The dyno (tune) can't fix poor atomization of the fuel (which is affected by the entire flow path, and injectors), hot spots, poor cam choice, engine setup issues, auto-ignition from wrong compression, incorrect or low quality fuel, and all other contributors to detonation.
