No, the PCV system is NOT for emissions. The purpose of drawing a vacuum on the crankcase is so that when you're cruising normally(where you spend 95% of your time driving) you don't get pressure building up in the crankcase that forces it's way past seals, causing oil leaks. Or you constantly have a mess on your valve covers by the breather.

Best trap 107.11mph, we'll see what the new intake/carb setup does.
