E30 M3 Evo front Splitter

[JiB 2]

I was doing a bit of research/procrastination with aero, and came across the first decent pics of the Evo front splitter that I've seen, so I thought I'd share. It's interesting that the bottom has what I can only assume is a venturi device. I wonder what (if anything) goes behind it?

Is it possible that there was ducting from the back of the oil cooler out down through there?

I can't quite see with the road car one (it doesn't appear to taper), but on the DTM's, bump could even be there solely to dump waste air nicely...where the vent is where I'd say the low pressure zone is. And the bump's shape is a half drop shape/lowest drag shape for that cross section.

But because the bump is angled, it chould also be pushing air around and away from the underside of the car (reducing underbody pressure)?

All speculation of course.

JiB, have you had a read of Jake's DTM symposium on s14.net?

No, I haven't? Would love to though? Do you have a link?
