My exhaust manifold is wrapped and I've got some of that flexible self adhesive hear shield to stick to the underside of the bonnet. I havnt
used the car in anger so can't comment yet!

Good airflow is the best method of keeping heat down.

I'm just thinking of a " belt and braces" approach

I have the exhaust manifold wrapped and also have a vent in the side panel on the exhaust side to encourage airflow past the manifold and out of the
engine bay.

I've propped the rear of the bonnet open by 5mm
Double wrapped the manifold, heat shields by the master cylinder and for the rear off the alternator after frying 2

I've mounted an oblong section of fire-proof soffit board above the header pipes.
It's a bit like asbestos board and available from local builders merchants for next to nothing in 2-3 mtr strips.
At the same time I bought a couple of big spring tool clips, bolted them through the board so they correspond to the front and back pipes, then slide
the clips over the pipes.
That way the board is easy to remove if necessary.
Even though the headers are wrapped it shows how much heat they generate as the board lasts about a year/18 months before the heat degenarates it.
An extra packing piece of board between the clips and board seems to dissipate the heat better so the board lasts longer.
HTH.
Cheers, Pewe10

I have a large CBS vent above the headers and a peice of heat reflective sheet underneath. This seems to help chuck a lot of heat out of the vent and
I can see this when I have stopped. Vents at the back of the bonnet help over cam cover heat and keep radiator flow high, as do side wind deflectors
going forward on the rad. The side wide deflectors on the rad stop air going through the nose, hitting the radiator and flowing round the sides, a
must have in my eyes. The after rad air is then helped to flow \ exit through side vents and not try to be forced down the transmission tunnel. I
also have a ali heat sink thing on my oil filter to suck air out of it and a cold air feed to said heat sink. On hard 30 min track sessions my water
temp is good but I will see 140deg+ on oil so I use high quality race oils to make sure they can handle this.
My only worry is the oil temp which I may try to solve with an oil rad. I already have an oil to water exchanger at the oil filter, not sure how much
this helps.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
