I am building a 71 Camaro as a dedicated track car. I'm using 275/35-18 up front. I was considering an LS3 but mynresearch says they have oil control problems using the factory wet sump. Will my car with 275 tires create enough cornering force to cause oil starvation?
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).
