Vacuum Pump Opinion

I tried dual aspirators, on the street. The engine seemed a lil more potent, hard to tell. But as the rpm went up the baffles in the valve covers couldn't keep up, and the exhaust system started blowing large quantities of oil. To be fair, I am sending more oil to the top than most guys would. I tried a few things but since the lil 367 had a preponderance of power anyway, I just retired the valves.
I say preponderance of power, but I really mean that the 295s (BFGs or Coopers) suck for traction. But I learned to drive it and discovered that I liked sliding around, so never took it to the next step.
Don't underestimate the power of those aspirators, they really suck
