After eight months of waiting (Never say no rush to someone in the car trade that I know now) I have now got the Taimar back.
Cheers Adrian for the advice it has had a full back to glass and respray.
However after driving it since, I have decided that it needs some form of cooling in the cockpit, when I bought the car I thought that fair enough this is how they are, (The later ones didn't have the side vent, bad move) but since having got back it is far too hot in the car even with both window's and sunroof open.
The shortest trip once the engine has warmed up end's up like being in a greenhouse on a sunny day, with this in mind I am thinking of putting vent's in the bonnet.
Arse about face but that's me
Likely for both the mesh and surround to be sprayed the same colour as the car.
Your thoughts please.
As it used to be.
As it is now.
pics of possible vents laid on top of the bonnet.
Thank's for your thoughts, Grant

I thought that they would get the sort of comments that you have given, Neil you are right about the NACA ducts they seem to be the way to go.
John it has got the insulation on the tunnel, it just that it would be nice to be able to go out in her and not end up looking as if I'v been in a turkish bath for an hour.

Some things to look at/try?
Are all the ventilation pipes connected to the vents under the dash? they can drop off the back of the vents.
Another (simple) option to try would be to bypass the heater matrix, very easy to do, just take the two connectors off the heater matrix box and join together using a short bit of pipe. That way all of your air intakes will be to the outside world.
Also what temperature stat are you running in the engine, the standard was 88 deg, but there are 74 and 81 deg stats available, one of these might help lower the under bonnet temperatures and therefore you won't get as much heatsoak.
What temp do your fans come on, could this be set lower to stop the under bonnect temps rising so much.
GAjon's suggestion of insulation is a good one, on the bulkhead and above the gearbox are good places to start.
I had a SE vent cut in the bonnet, certainly lowered under bonnet temperatures and allowed hot air to escape especially in town driving.
Hope that all helps

1: All vent pipes ok.
2: Next to be done is the heater matrix but think I will be putting in bypass pipes in with taps on so it can be brought back into use as and when needed.
(This could be one of the main problems as the heater box flap seems to be a very heath robinson affair and I don't think it seals very well)
3: Stat temp I have got to be honest I don't know, but have electric fans on the radiator that are turned on by myself in the cab as and when needed.
4: Insulation is on the bulkhead and over the gearbox.
5: Vents, should have had this done before having it resprayed but after not driving it for eight months had forgotten how hot it gets in the cab, so are now looking for some form of vent that will fit without having to respray the bonnet.

Fit A/C. The best thing I ever spent my TVR money on was A/C. In Canada round Montreal and Toronto it is really hot and humid in the summer but with A/C I am very comfortable in the car (although when stuck in a traffic jam it gets overwhelmed if the temperature is above about 35 C).
Opening the roof or windows lowers the pressure in the car and sucks in the hot engine air through the bonnet releases, round the switches and ashtray, and any other leaks into the passenger area.
My car is hotter than most being a TVRNA 5000M with a Ford 302 V8. TVRNA fitted the A/C for about $5000 Cdn.
The A/C really makes the car very pleasant. I can close the windows and hear the radio! When the windows are open the A/C compensates for the extra hot air sucked in. Demisting the windows is really quick! When I want a TVR I have one but when I just need daily driver transport and need to arrive relaxed and cool the car will do it.
No sweat!

That would be to easy, I have the Mercedes for A/C, the TVR is for getting back to basics, but with a few comforts.

You must be one of the few that recognized the old girl, keep meaning to send Phil some updated pics, like I promised in January when I thought it would only take a couple of months to have her stripped back and resprayed.
Thanks for the input guys

I have fixed similar Air-Vents as the old Griffith have ( like Jaguar E-type as well ), sidevents of the 2500M and made some holes in the inner Backplate of the middle of the Bonnet !
All works fine and looks right .
Any chance of some photo's, would be nice to see what works.
