I have pan evac on my Jersey Speed Skiff with wet exhaust, works perfect, /chrylser check valves and chrome breathers. Check it out Daze of Thunder js-70
I plan on installing one but have the same question...how is the vaccum affected at higher revs or at full throttle? The manufacturers aren't much help.
g'day mate. i have just fitted this system to my general motors holden aussie v8. its 304cui and it has .5 inches of vacuum at idle and and 6 inches at 7400rpm on the dyno at work! they work awesome, and they are mounted in the collectors just in front of the racing mufflers
Nice video disproving a common misconception. I don't know why people think mufflers would stop a pan-evac from working completely. A siphon sand blaster has a restrictive nozzle on it's end (muffler) and just the flow of the air past the siphon hose (exhaust gasses) lifts the sand (pan evacuation) anyway. The high speed exhaust gasses creates a venturi effect and those exhaust gasses exist regardless of what exist past the collector.
on my renault 5 gt turbo i have what i think may be a crankcase ventilation issue. on start up and also sudden acceleration i have black smoke but it doesnt seem to be losing oil. it had a new engine about 2 yrs ago and new turbo about 4 and yes i sit and warm it for 5 mins and cool down 2 - 3 mins! the metal pipe off the elbow gets coked up and also the c/case filter and metal pipe that that sits on also has oil inside. any ideas??
Do you think the exhaust gasses are flowing faster at full throttle than at idle? If you would buy into this theory then you have your answer. I'm not sure if the relationship is linear but it could be close.

Put a vacuum gauge on there and go drive it shifting at 7k or so and let us know how it works.

Good job al, im getting ready to do this myself and your video just re-assures me that it really works.. Thanks. Nate from steves site.

Ok....now, run it at WOT and see if it sucks. At idle who cares if your evacing, you need it all the way through the RPM range.
