Picked the car up this afternoon and drove it 250 miles home. What a fantastic bit of kit. It’s a T350c with a Powers 4.3 and a 3.9 final drive. I bet it’s nearly as quick as my old R500.
Anyway, all good apart from the heat. The whole centre tunnel seems to radiate heat, even the alloy gear knob gets hot. Not helped by the fact that as soon as I got into traffic I got “aircon fail” come up on the warning panel. Seemed to work reasonably when motoring along.
Is all that heat from the engine or is it the cats? Has anyone successfully managed to reduce it significantly?

Thank you all for your help.
Just been reading the advice from Graham Varley - looks like I've got some investigating to do to see what set up I have and them possible some adjustments to make.
Sounds like I could improve the heat from the tunnel by replacing/improving the insulation another job for the list. If anyone has a link to any specific material that has worked really well I would be very grateful.
This ceramic heat break for the gear stick sounds a very interesting solution - anyone got any links to where I can find one - tried google but not having much luck.

Powers sell the titanium gear lever - it is the shaft you refit the knob. They also sell an alternative knob which I like.
I have a set of Clive F 200 cell sport cats (original ones have started to breakdown) which are smaller and replacement manifolds ceramic coated ready to be fitted once I can source some 12mm four-wire o2 sensors. At the same time I am going to add exhaust wrap to the front of the exhaust pipes up to the cherry bombs.
Just googled CliveF - he's on the South Island, not far away at all. Might talk to him about the problem and see what he suggests. If I can make it cooler below and add insulation to the tunnel I'm hitting it from both sides.I have a set of Clive F 200 cell sport cats (original ones have started to breakdown) which are smaller and replacement manifolds ceramic coated ready to be fitted once I can source some 12mm four-wire o2 sensors.

What's the legality of decat on these cars?
I know after 1992 any car fitted with a cat has to keep it, but it looks like TVR slipped through the small manufacturers loophole and didn't get emissions tested so at MOT there's no standard for them to meet. Seems to be a bit of a grey area.
What have others found? If I could take the cats out of the system and wrap the exhaust tubing I would save a whole lot of heat build up in the tunnel.
