Oil surge in track GTR cars

[Chris Wilson]

Opinions sought on controlling oil surge on race RB26 engines used in road course track cars. I know one of the main problems people racing a GTR have is oil surge. I have an RB26 GTR engine in my R33 GTS-t track car. I am using a cut down GTR sump (diff hacked off) with a Trust extension and Trust baffling. I am not entirely happy this is going to be enough. What are people using in slick shod GTR race cars to control surge? Has anone dry sumped a GTR engine? I am toying with using the stock location mounted Tomei high capacity oil pump as a pressure pump, and having a 2 stage external scavenge set up. Not sure if the pressure side oil routing can practically be plumbed to suck from an external dry sump tank though, not fully weighed that up yet. What did the Group A cars do? Thanks.
