Neither were these cars:

Perfectly ok.

Blow-overs aren't caused by turbulence. They are caused by the pitch-sensitivity of the large flat underbodies that are required by sanctioning bodies. They occur when the underbody presents a positive angle of attack to the air flow and creates lift. By virtue of the fact that the Deltawing has significantly less underbody surface area in the nose of the car, I would argue that it will be much less likely to suffer such a fate than a more traditional car.
But don't forget that with the significantly smaller underbody area, is an equally significant reduction in weight on the front. Additionally there is even less downforce being generated at the nose, which seems to be designed to actually gather air under the car:

I see that long nose as an effective lever to expose the wider rear to more air as well.

You do realize of course that all LMP cars generate the majority of their downforce with the underbody, right?
While keeping a large aerodynamic device up in cleaner air. And without encouraging lift at a lightweight nose.

Few race cars ever do.
And if so, the DeltaWing will be known as another flop that was only notable for its looks.
