Boy did this thread take a wander.
Back on topic though, i guess it would make a difference but it may vary between a gasser and a diesel. The heat output from a gasser is much higher than a diesel so you may get plenty of heat going to your intake, which would give good lean burn-ability. Warmup times may not be quicker due to the thermostat opening when the engine reaches operating temp.
In a diesel there may be scope for the intake being the sole means of airflow to the radiator. The reason i say that is that mine is currently completely blocked off. There is some air getting to the radiator due to leakage from under the bumper etc. but it's grille is completely blocked all the same.
But what is the optimum air temp for a diesel in terms of FE?
