his theory didn't really prove his point ...
but his whole post picked him up ...
there's too many factors left out here ...
the larger surface area...
the amount of air flowing
the surface area drilled out
speeds to stop
stock vs aftermarket heat tests and so on...
i understand the issue here is slotted/drilled vs solid ... so i see his points give all things equal...
but stock vs larger and so on... is another interest...
great find btw....
