Very interesting, Peter. So it was some guy of the MMC staff you had as a guest?
When I think about it, MMC didn't actually need a new tool, they just machined the hood the other way around with the direction of the louvres. And if you compare pictures of old 1980 Plus 8 with a roadster, it's actually obvious that the new way of making the louvres draws the air in more effectively. But...it remains a low pressure area.
I would say, however, that the air intake on the open scoop as on the P4Supersport or also on your Plus4 certainly has advantages. That's what I mean because the air intake is much more outside. If you look at the US video, then the area where the scoop is located is not in the direct negative pressure air area as where on the other side the Roadster opening is located. The scoop is located more in front and above where the fabric strips in the video are still blowing. So it is a good thing.
And I recall that the scoop was effective. Ones I changed the overall oval air filter against filter sockets on my former P4SS and the gain was dramatically lower. So, there comes in enough of fresh air to create such a difference.
