Posted February 3, 201411 yr Pretty simple question here. I am going to put together a BLDC. (boost leak detection contraption) as I feel I have a small leak in the upper boost pressures (only seeing about 24psi) What do you use, how did you build it and what parts are used to build it?

February 3, 201411 yr Author Thanks Mike, I had actually just watched your video and it made me ask "what did Mike use?"
February 3, 201411 yr Are you sure that you're getting the "fueling" to produce the "boost" that you want??? Boost is a "resistance to flow" ………to quote AH64ID………………..you need fuel to produce boost. Make sure you've got it!!
February 4, 201411 yr Author I would imagine I have enough fuel to get over 24 psi. I'm running a hot unlocked edge comp with plenty of fuel pressure. But maybe your right.
February 5, 201411 yr Author No sir, I have some black smoke (very little) but EGT's never get over high 1100's.
February 5, 201411 yr do you have a boost elbow on the turbo or something else to keep the waste gate closed until higher pressures are reached?
February 5, 201411 yr I would imagine I have enough fuel to get over 24 psi. I'm running a hot unlocked edge comp with plenty of fuel pressure. But maybe your right. I have the same setup and can hold 35 psi. Without my boost elbow I could spike 45.
February 5, 201411 yr Author That's what I would expect. I am sure there are many possible factors, I may have an injector or two getting tired, may have a boost leak. Not sure but as always the mopar family helps narrow things down. Thanks guys. Any other input is appreciated. Edited February 5, 201411 yr by Gamble

Not sure but as always the mopar family helps narrow things down. Thanks guys. Any other input is appreciated. This why I typically suggest the compression test and pop testing of the injectors together. Because if your going to yank the injectors out to pop test you might as well test the cylinder health too by running the compression test too. Now you know the cylinder health and the injector health in one pass with two tests.
