With turbos so much in the news lately, and on this forum, May Madness will have talks/vendor booths from:
Holset
BorgWarner
BD
ATS
High Tech Turbo
Piers has said he is coming, but I don't believe he will have a booth. He hasn't registered yet.
I suspect at least one turbo vendor will bring "examples" of products. This will help those who might overly "flex" theirs on the dyno or at the drag races.
