NigelH Posted June 27, 2020 Report Share Posted June 27, 2020 Jase, As mentioned, ceramic coating of the manifold is a huge radiated heat reducer or thermal tape wrap. Improved airflow around the carbs helps a little too.. Not seen any examples of water cooled inlets for TR4's..perhaps more learned members have.. Nigel H. Quote Link to post Share on other sites
AndyR100 Posted June 28, 2020 Report Share Posted June 28, 2020 I don’t think anyone has shown an example of using a 2-piece shield, as mentioned earlier it removes the linkage puzzle and simply concentrates on shielding the float-chambers (ignoring the question of whether it is, or is not, necessary!) ........

Graze Posted July 8, 2020 Report Share Posted July 8, 2020 So having rebuilt my TR4 (mostly Racestorations supplied parts) into a high out put fast road motor I was having all sorts of problems getting the car to run when warm. It was generating so much heat under the bonnet that fuel was vaporising in the fuel lines ( they were measured at 92deg C) as well as in the webers. wrapping the extractors, sheathing the fuel lines, installing two layers of heat shield between the webers and the extractors and directing cold air to the trumpets and to the air space between the heat shields ( plus upgraded electronic ignition, rebuilt distributor) solved all this Now runs like I'd always hoped Quote Link to post Share on other sites
