Viggen Overboost
Posted: Wed Oct 23, 2013 11:05 pm
Been having an issue with the boost on my Viggen surging way into the red... To the point where it hit fuel cutoff.
This is obviously bad news for the engine, turbo, tires, etc...
Testing yesterday also yielded a situation where it have no boost. Then to much boost again.
I went to unplug the boost control solenoid today to eliminate it from the loop, and it fell completely apart!!
Naturally, I have a spare and swapped it in. It now appears to boost normally!
So the question is: will my turbo now suffer a horrific fate due to it's abuse? I think the compressor seized for some time yesterday..... I guess time will tell.
Also, first drivetrain content is turbo related!
