It was no joke, I think everyone is losing sight of what we are doing with this and I do understand the positive crankcase situation. This engine, as many across the country does, ran fine with just a pan evac system. This pump moves way more volume than that ever would. it is only to remove moisture I don't think it will pull over 1 or 2 inches of vacuum on a pass.
Keep in mind that a pan evac system is an open system. It's not being limited by the speed of that impeller within the electric pump.
Just to clarify something though. I have a mechanical pump on my car and we have one on the dragster that we have also. I posted this for the guys who always ask questions, which I have seen a hundred times, about how these work on an engine. I do appreciate the concern for our safety but we are not a bunch of newbs trying to do something with $12.00 dollars in our pocket.
The problem is that you never mentioned (unless I misread the post several times) that you also have a mechanical pump on the same motor. Nobody ever called you a newb or insinuated that you were poor.
AGAIN guys don't lose sight of what we are doing with this we are not trying to pull vacuum to make power. This car is tire limited with a 14-32 so we have to kill some bottom end as it is. I am not trying to be adversarial about this I just want everyone to understand that we do have a pretty good idea and knowledge about what we are doing, this was just for the guys who can't buy a Star or Moroso and would like some info.
Look at it from an outside perspective. If nobody knows you also have a mechanical pump, and you say this thing works, but because you know what you're doing it's not explained thoroughly in the post, someone who's wanting to do it on the cheap may want to try it (run on sentance, sorry).
Some young adult Johnny may try and put this on his big block street motor that has 14%+ leakdown when cold, push all the oil gaskets out at the top of the track, spray oil under the tires and wreck his car and hurt himself.
I'm glad it works for you. The hazards if it doesn't work for someone else also need to be pointed out so the end reader can determine if the reward is worth the risk.
