KAWASAKI ZRX1100: As a test control, we fitted the Pi System to a non-ram-air-equipped motorcycle. If you think figures like 17mb seem insignificant, take a look at how much vacuum is present in a regular airbox and you'll realize even that amount of positive pressure can make a huge difference. With a pressure of -27mb, it's obvious that power gains can be realized by converting that vacuum into positive pressure.
