KEEP BEETLE ENGINE COOL and CHANGE JET FOR E10 and other tips for ignition timing for Ethanol petrol etc etc.
In other words, ensure air is directed into engine compartment, and also sealed - if possible

A very interesting video and some points that I am sure are news to many people.
Of course a lot of the stuff about seals and keeping the heat separated within the confined space of the Beetles engine compartment is not relevant to our cars where the engine is more or less open to the air around it and lots of room for heat to disperse.
I am in favour of rear vents in valances (I have the mesh to do just that below the bumper as soon as I get time) and as hot air rises, in engine lids to aid air flow and the more the merrier and deflectors under the rear of the floor pan to guide air flow up around the gearbox and under the engine is a good idea.
FYI The 'tins' I use are all alloy and have a centre mounted alternator with internal deflectors and the cylinder covers extend well below the normal to past the headers with T4 deflectors under the barrels (Over the tubes), which vastly improves the cooling plus a duct from the right scoop to the fan area of the louvred bulkhead and another from the left scoop to the oil cooler in the rear deck as suggested with a vent in the rear of the lid. All of which will be of little interest to the average Nova or SS builder if they are running a stock VW engine and tins but trying to seal off the whole engine bay of a Nova/SS would be a huge job and due to the very much larger area around the engine, unnecessary as we have scoops to get the air flow needed that the beetle does not, so concentrate you efforts in ducted air flow and heat dispersal relevant to the design of the Nova/SS.
