Good call Peter, i see that the engine was released on recently.

Heres what I read in an article

"the inclusion of a double overhead cam Nissan motor represents a change in emphasis for the class from technical parity to performance parity. According to COTF project leader Mark Skaife, the performance process that the V8 Supercars is currently working on will enable the incumbent manufacturers to join Nissan in running newer-technology engines. The current 5.0 litre Ford and Chevrolet motors used in the class are bespoke to V8 Supercars, with the blocks and cylinder heads made-to-order for the teams in the United States."

And it looks like theyre gonna limit them at somewhere between 600-650hp

This is great news in my opinion. It opens the door for ford to use the new Coyote engine thats in the FPVs.
