All of the engine cooling aids such as aluminum intake manifolds, header pipes and extra large radiators depend upon dumping their heat into the engine compartment. What’s needed is an under hood cooling system to remove this heat build-up when there is insufficient road speed to pull the hot air out of the bottom of the engine compartment.
The stock Tiger hood latch is set up with a “safety catch” which holds the hood after the striker bolt has released. It has always seemed that when the Tiger was in hot weather, it would run a little cooler with the hood “propped open” in the safety position. This is especially true at slow speeds when the hot air gets trapped in the engine compartment.
