Help please. No boost :(

[BaadVR4]

If one turbo goes bad, you MIGHT get as much as 9-10psi boost on the remaining turbo, depending on what failed. If there is a path to atmosphere from the broken turbo (i.e., zero boost from failed shaft), then the boost from the good turbo just recirculates through the bad turbo discharge pipe back into the suction side of the good turbo. I know.

I have a lot of "no boost" experience. My experience with a system that loses boost instantly is 100% turbo failure. From seized shaft to broken shaft to worn out housing/compressor wheel, every one has been turbo failure....just my 1.5 cents.

Believe I found the issue. Ran the car in limp mode with pre turbo pipes off. Both wheels spin. Had a camera on the front wheel to get a better look, when we shut the car off I noticed a piece missing from one of the blades in the turbo. Pulling front turbo tomorrow morning.

It might be this :

"piece missing from one of the blades in the turbo."

[ItTricky]

Kinda what I figured lol. Front snail is coming out in the a.m. .... and it's the same turbo that seized on me last spring.

Then I would be investigating the feed and return, assuming the turbo(s) was(were) properly balanced to begin with. 2 failures at the same point sure smells fishy.

EDIT - what turbos? ever surge/compressor stall?
