Bonnet Scoop Removal
Just toying with a couple of ideas, and wondered if their are any adverse effects when removing the bonnet scoop entirely when fitting a FMIC (with necessary supporting mods etc). If the hole left in the bonnet was blanked off or if a non turbo bonnet was added, would this have any impact on circulation and engine bay temps?

OK, I asked the same question when I went FMIC, but instead of asking on here, I asked the late, great, Harvey Smith.
Harve, of course, didn't have an opinion...oh no...he'd done the research. He always had.
His findings were:
For cars driven on the road, track etc, DO NOT replace the present scoop with anything different, facing backwards etc etc. If you do, it will raise underbonnet temps to an unacceptable level.
Cars used for short bursts, like drag, time attack etc are fine. Road cars suffer the worst. and yes, it does cool the gearbox...Harve tested the gearbox oil temps with the scoop, without, with a backwards facing etc etc.
He was an engineer, par excellence, and is sadly missed.

So the intercooler act as a duct channelling air towards the gear box? But without it there (fmic) isn't the air pretty much scattered?
I would have thought if you leave the sump guard / under tray off with a reverse scoop that would be pretty effective at lowering under bonnet temps on the move
