Who here has done a boost leak test on their RB?

Discuss the RB20, RB25 and RB26 series engines.

Ran a boost leak test and fixed a slew of leaks. Having the hardest time trying to pinpoint what seems to be like my last few leaks. Anyway I'm curious as to how many people have done them on the Rb engine and how long and what psi they can hold air in for...

Right now I can only hold 5-6 psi in for about 5 seconds before it all leaks out.

It's not going to hold pressure long. As long as you have all the hissing sounds taken care of, your good.

yeah, just remember to plug your recirc hose off the bov, and fix all the hissing. There will be open valves, so some air will get past.

ah ok thanks for the help.

with no other RB engines around me its tough to figure out what it should be like. We tried doing a leak check on my boys SR engine and he held 15 psi for like a minute. So I thought mine should have been like that too...
