Mark, as always, great post.
I can't argue with anything at all in paragraph 1, and 5 to a point.
Paragraph 2, We're not using parts from other cars as in your example, its still all B44.2, its just adapted to its racing environment. People change oil many times at race meetings chasing set ups, I don't see a difference.
I know how many spacers to add and remove so its takes minutes to do. Just the same as if you were changing droop or a piston.
The boost in buggies, I thought people just motored up, seems I might be missing a trick so I'll try that but your right in what you say I've never really like the feel of boost.
Good debate so I'll add more when I return but for now would it help you if you thought of it as setting them up as we did in the early 90's before touring car existed!
Pro-Cats for the Win.
