Probably but why put holes in the bonnet - just raise he rear a bit with spacers on the hinges

That's my original idea then, but a differing solution....somehow getting the airflow over the engine and out the tunnel,, after all, there is a dead space trapping air above the engine and as heat rises that's why I think the scuttle area seems the hottest in a se6. Wonder if anyone has tried an air scoop on the bonnet then?

Yet again, many years ago, I was the original builder of 'fart', the highly tuned cox gtm that cars and car conversions later raced and wrote articles about. When I put the twin webers on, I had to modify the hump on the bonnet/boot and soon found that it worked better scooping air and not venting it! Interestingly she is still around.

I was just addressing the theoretical aspect, but was aware that some people did this. Mind, in aesthetic terms, I think neatly installed vents (if you must) is better than having what the iggies might simply call a 'badly aligned' bonnet! :lol:

At the Bicester "Super-Scramble" yesterday I picked up this fan (for £3), which I will be fitting behind the radiator; I have the standard Reliant fan in front of the radiator; this is not close coupled and tries to push air through (most of the air goes round the outside of the rad!).
Does anyone know which cars used the 3-point mounting on the fan motor? I ask, because the original Reliant fitting on the Sabre Six is the same - does this mean I've bought a Sabre/Coupe fan?
I want to keep as much originality as possible, so adding this as an auxiliary fan suits my aims. The fan blades are aerofoil section and designed to fit in front of a radiator; the blades clamp screw is seized in spite of the Plus-Gas so I won't be fitting it the "right" way round.

I think I’d duct the existing fan properly rather than fit another one?

Being a more modern yellow plastic, it’s also totally out of place in a Sabre engine bay :cry:

Coupe mechanical fan behind the rad which is ducted. I’ve also an electric auxiliary fan behind the rad which is rarely required.
