If you buy from Peter Howells at LD parts you can get a document on Stag cooling. One of the things in it is that the number plate holder that Michaeloti designed was for an Italian style plate which are much thinner than ours.
Having been a R&D engineer in a previous life my curiosity was aroused and I wanted to know how much it affected cooling. I therefore removed the number plate and holder and with the aid of some thick rubber washers mounted it above the bumper instead of below.
The temperature gauge normally runs at just to the right of the vertical and now with the plate moved it runs slightly to the left. As you can see from the picture the lower vent holes are no longer covered, and I suspect that there also is less turbulence from the plate.
Unfortunately without access to a wind tunnel this is mere speculation. I will however refit an electric fan as on hot days on the continent I fear my nerves would be in tatters without it.
