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?
All I have at this point is the car which I bought as a shell. I have restored the body, added the wheels and tires (NT01s) and cage. I have no idea if it will exceed 1G or not. I was planning to use a trap door pan. Maybe the Accusump will be sufficient.
I have very little knowledge or experience, however I used a Champ Road Race pan on my engine. Have done a couple of the Run to the Coast events, and watched my pressure thru a few corners, and the pressure never budged. They have trap doors and holds 8 quarts.
Based on what you have told us, for your setup (2nd gen, 275 series NT01 tires) I would not say you will be outhandling C6 Vettes with Hoosiers unless there is more to the story. Some of those guys are having problems with sustained high-G corners but not all of them.
I am a big fan and advocate of dry sump, but it is expensive and would not do it unless I deemed it absolutely necessary.
I think you would be fine with the accusump.
Until it blows up (hey, Ron said it first).
