Great photo

A really nice shot of Chris Burkett in close formation with Pete over Gibraltar.

Notice the inlet (in white on the top of the cowl) for the engine air.

It seems like an attempt to get colder more high pressure air into the engine for more power.

If it's not sealed to the rest of the low pressure area of the cowl then the penalties could outweigh the benefits, because as we know introducing high pressure air into the low pressure area of the cowl reduces the difference in  pressures and thereby reduces cooling efficiency.

It will be good to have a closer look at what Pete has done here before drawing any final conclusions.
