I tried the hoses to the collectors at the track (not this car) when that stuff first came out. Never found a thing. I tried a slick little check valve with two PVC valves and a closed crank case on the dyno. Pulled good vacuum to about 5000, then it went away. No pressure as high as we were pulling it then (7700) but no power gain. Finally went to one PVC on one side, and a breather on the other. It's a legal vacuum leak, so you may as well use the highest flowing PVC valve you can find. LOL No more condensation in the valve covers that time of the year either. Didn't back-to-back-to-back it, but appeared to be a couple above 8000. Guess it depends on how well yours would like a larger TB.
