Running full race (longer duration events, full slicks), then an Accusump is the minimum insurance, but serious amateur or semi-pro competition then the only solution is a dry-sump system.
I track my car regularly, use Yoki A048 or Dunlop DZ03G R-Spec's, and once a year run in a 6-hour relay where duration is 30-minutes and I do not get surge with a JWT sump extender, oil cooler and an additional litre of oil in the engine.
However, if I was "racing", I'd install a Dailey Engineering dry-sump.
Tread you own path, make your own decisions.

The car is a DD on street tires and we run 25 min sessions, nothing serious. I just want to have as much safety for the motor as I can have reasonably. The car has a lot more power than the last time I tracked and I want it to stay that way. Last time we went to Sebring we trashed the motor of a 650 HP Trans-Am because of oiling problems and it has me a little gun shy.
Thank you both for your input!
