Title: Hard tank shape with crankcase pressure
Post by: Dennis Toth on January 05, 2017, 04:49:11 PM

Guys,
What is the recommended shape for a hard tank with crankcase pressure? I'm looking to build an OTS ship for windy weather conditions. My approach is to have a ship that will use a screaming combat engine to pull the ship at 60 plus mph and fly on long lines to keep it flyable. So I'd like some advice on the tank design and plumbing (uniflow or conventional pressure line).

Thanks,    DennisT

Conventional.

Whether it's muffler or crankcase pressure, the uniflow does not function.  It just blows bubbles.

The best way is to have the pressure vent high & dry.  In the past there were pressure dome tanks to ensure that the pressure vent is not submerged. If the vent is submerged, be sure to keep it pinched while starting.

Look at the VooDoo tank set up.  It works.
