Cause of failures seems to be carbon build up, corrective actions taken by cummins are to cycle the veins while the engine is off in order to keep carbon from building up on them and freezing them up. From what iv been reading since braineak posted cummins are the most reliable of all the turbo diesel trucks, ford being the one with most of the issues.

Can't you increase spool with your EBC? I know I have mine set up to hold boost until 5 psi then by then EGT's are increased and it spools really fast from 5-15 psi, only down fall is it takes awhile to reach 5 psi...not sure if this is a similar concept?

so from what i can gather, this valve is pretty much for drag racers with really big turbos.

"Vanes" just so we're all accurate

Has anyone been able to make a good tune with the turbine inlet EGTs below 1400f or so?

On HUGE diesel generating powerplants, some use N2 to pressurize the exhaust manifold to spool the turbos which obviously helps them crank up. I was once thinking of shrinking that down and one utilizing something like that with a rpm/pressure window switch to dump N2 into your exhaust housing at a certain angle and help spool... the angle will effect speed of rotation and ideally you'd want multiple angle of injection, but ultimately you're still dependent on a bottle, and I'm not sure how that extra N2 (which is inert and 75% of the atmosphere) will effect the wideband.... if at all. I'm in the refrigeration business and the small N2 bottles are like $7 exchange which makes it MUCH cheaper than N2O. It wouldn't be that big of thing to try and see the reults... we'd have to fabup a housing and try it out and see what the results are...
So is this a dumbass idea just to spool a turbo quicker?
