In this context: Has anybody experimented with shaping the clam shell vent holes for optimized hot-air extraction? Of course we've seen the scoops on the MK II guiding air into the engine bay but they create draft.
I once tried a lip at the front boundary of the alumin(i)um cover but it had an adverse effect and I think I know why.
So I had a brain fart! I’ve made a few flairing tools with the 3D printer, so made one for the grill! Turned out great!!! If anyone wants the STL file to make one them self, just let me know and I’ll send it over! Works a treat! If you don’t have a press, you can stick it in the vice and works just as good!
