Right

I see that the thread has been face lifted - Thanks Jay . ?Just for the record - all relevant is appreciated irrespective from whom

I have now read the article on the Compressor Maps - Nice one Chip - top article


Soooo Lets see if I can answer the question posted - Basically, surge happens when the turbo is providing more air flow than the engine can manage - which leads to the excess air rushing back towards the compressor.

Therefore - lots of boost showing against minimal flow is effectively like a blockage in laymans terms,. Is that corect?
