What a great read, just shows that it's not just high performance cars that can benefit from some quality engineering, just need someone here to have a go and share the results.

Many moons ago, I fitted a pair of louvre panels to the rear of a Vitesse bonnet, to solve a completely unrelated problem! The car had been fitted with a GRP bonnet that just would NOT stay shut at speed, indeed if the catches came loose at anything over 70mph the rear edge of the bonnet would lift halfway up the windscreen, demonstrating irrefutably, just how much air pressure was being produced with no effective way out!
A pair of cheap hold down pins solved the lifting, but it got me thinking about the more elegant solution and I let a pair of louvre panels into the bonnet, as far back as was possible and the results were astounding! The car was faster and more stable at speed, the engine ran cooler, fuel vaporisation in hot weather was almost eliminated and, as a final bonus, the windscreen defrosted quicker in cold weather!
Thats what I call win win, win, win, win!

The best place for air vents is where the largest pressure difference either sides of the panel.
I find this stuff fascinating but have still never done anything practical about testing it, which actually sounds pretty simple and cheap -

Steve bought the gauges to do just this on his dolly but we didn't get round to doing it and the cars has been off the road since. One day though.
