here is a video that goes the theory and the tests that show the issues each can create.

what you need to consider is i think he say in the questions that the turbo on the can has an anti surge compressor housing, so none antisurge compressor housing like the standard VR4 turbo will be effected a lot more by surge.


the testing he does is not complete but it give a good indication at lower boost pressures what the outcome would be.

it is a shame the full testing was not done on a full ramp run. but it is a topic for conversation.
