Leak down testing

Go to this link. You have to know what percent you want to set the leak down.

many thanks guys awsome web site my questions have been answered.

 

Be careful on interpreting everyone's "lingo" on this subject. Goodvibes says to read leak on the second gauge...the number on the second gauge actually tells you the leak % returning to the tank (unless you have a reverse numbered gauge). Most will say leak your k valve around say 75-78%. That is 75-78% of leak going into the motor, so the second gauge would read 22-25psi. In the video it looks like they have about 33% leak RETURNING to the tank...so it's actually at 67% leak to the motor. Notice the second gauge goes to 0% leak to the tank when the blades are opened.
