If you look at the TDs, they are designed to carry 1000lbs, and unless the pre-chambers are different in Europe vs North America, I doubt that 60mph was the target. Probably more along the lines of BSFE and emissions, and emissions is why the 606.97x got the inclinded injection pre-chambers, I'm just not technically savvy enough to know why and how it affects the burn.

As far as angled holes, I was thinking in a way to create a rotation entering and exiting the pre-chamber, rather than a straight radial drilling. It doesn't seem like it would take much angle to create a swirl.
