Cerbs have never really had a problem with heat on the move though, have they?
Nope. But never put frozen food shopping in the boot if you plan on travelling a distance, like more than 5 miles.

The majority of overheating problems are when the car is stationary, which a bloomin' great hole in the bonnet isn't going to help much.
Although spending 4 hours (most of it stationary) getting out of Silverstone on GP day in warm conditions mine was OK.

I don't know. I can just see the engine itself being sat in a load of stagnant hot air.
Well when I've had the bonnet up checking my fans are coming on correctly the amount of hot air in between the engine and radiator is immense!!
Bonnet vent seems like a good idea to me especially for situations like driving round town when the airflow isn't so great...

But you've all a lready got great big areas for getting rid of the hot underbonnet air, it's technically referred to as the "big space between the car and the ground" - how much air do you think flows through the rad? .. not as much as can travel down the transmission tunnel and under the car that's for sure.
My mate Brendan did the 4.2 conversion, top bloke - done many a crash damamged TVR before. Car looks the dogs, although it is overpriced I would say. I also thought it was Cat D though, but could be wrong ..
Brendan's work is first class so no probs on the repair, I think he was talking about having the car inspected by one of those insurance-inspector type places that used to be able to take cars off the register, that doesn't happen now but you can get a "this car is repaired to a very high standard" type piece of paper from them, the fact Brendan was willing to do this last time suggets there really shouldn't be anything at all wrong with the car, to pass these tests they really have to be better than std!

Julian, do you think that the best place for all the air passing through the rad is under the car!I first put one of these vents on my griff bonnet for high speed stability, not for cooling,and it helped greatly.If it helps cooling,and i am sure it does,that is an added benefit.
The airflow under the car would be relatively insignificant from what flows through the rad, and anyway if you create a low pressure area under the car by venting everything through the bonnet you only get air spilling in from the sides to fill the low pressure area anyway. Air is going to find it's way under the car, unless you put skirts on it, so that air may as well be the radiator air as air from the sides? The main problem you had I would imagine is that there's no where near enough airflow through the rad, so most was bypassing and going straight underneath anyway ? I think this is the reason the front small aplitter is so efective on the griff. imo obvioulsy.
