Following this as I just assembled a race engine using a "W" case without a windage tray, and it does not have a dry sump, only a tuna can.

Am I going to have issues in high G corners?


Maybe...

One thing I'd add to ANY wet sump competition car is an Accusump.

This will give you 30-60 seconds more "Oh Shit" time before damage.

I'd want my MAIN pressure reading directly past the oil pump.

I DON"T like mechanical gauges (due to hot oil in passenger compartment) but on a competition car I'd DEMAND a mechanical gauge and if that puppy "flickered" during long sweepers I'd be adding a windage tray (a custom one in the case of the T4).

I'd want my Accusump connected to the oil system as far away from the first pressure sensor as possible. If both critters are close, you won't see the "Reaper".

I spec at least two pressure sensors for a competition oil system. The secondary ones have always been electrics for me.

Modern sensors are available that report both pressure and temperature. 

Oil control and temperatures are one of the most important things to upgrade for combat roles in my book.

Another NICE thing about the Accusump is the fact that you can pressurize the oil system BEFORE the crank rotates.
That ALONE is very valuable to me.
