Hey NeilW,

I am thinking that the Mod is feeling the extra heat because it is in fact damaging the efficiency of the fan to pull air away from the rear of the radiator. The purpose of the shroud is to direct the air& heat coming thru the radiator to the fan for removal effectively. If you put holes in the shroud it no longer is working as designed. To move more heat away from the engine you make the radiator larger, the fan larger or the same fan faster, or some combination of those three.
Just imho.
