Interesting read Stu, i always like to read yolur essays where possible they are very useful. I spend a lot of time in WHSmith recently
Now.........ive read and understood what you've said. Now i know there is this massive fued about dump valves, but as you've written when running high boost and the turbo surges, it places high loads on the shafts and bearings.
When would you say is a dump valve a necessity, if at all...? And what turbos would benefit the most from it
