When does a dry sump become necessary?

[GregWeld]

So I'm no expert on any of this -- but I went to the Lotus dealer today to get some info and some parts --- the service manager seemed quite knowledgable and we discussed many things -- including the tires I planned to change to -- Hoosier R6's.... and imagine my surprise when he told me that if I was going to up the cornering capability that much (over the Yokohama AO48's) that I should consider changing the oil pan to a model that will control the oil better -- "even though the car comes with an Accusump".

My point in all that typing is that it apparently is a more complicated answer than just "should you or shouldn't you" run a dry sump.

What pan and how much oil control/windage do you plan to run... and what's the SUSTAINED corner loads etc.

Take turn 2 at Thunderhill.... where you're in that decreasing radius turn for quite awhile.... and if you can manage that corner at better than a G... maybe a dry sump should be under your Xmas tree. Maybe for running peanut course AutoX --- it might not be important.... and an Accusump would work fine along with a decent pan?
