Now zing the throttle to redline with an overzealous heel/toe downshift and the oil pickup cavitates causing temporary zero oil pressure and connecting rods sticking out of uncomfortable places on the casing. A bad day.
If you keep your oil topped off, run street tires, and stay well away from redline in the sweeper you have little to worry about. An SPBOX driver racing in a pack on fresh comp tires, not paying attention to his oil situation is likely to get bit at Fontana. At least a dozen Boxster Spec motors have been sacrificed entering turn 3 Fontana with a big redline (money) heel/toe downshift while reaching for 2nd gear.

I see what you mean with T3: such a long left sweeping braking zone to starve it of oil

Would this imply that in a right sweeper under acceleration the opposite scavenge pump would be starved for oil?
