For those of us that have the MK1 with the dual nostrils you will notice that only about 60% of the fan on each side exits through the nostrils. Last summer I was on a mission to find out how to cool the cab and took some IR readings while on the road. I drove the car hundreds of miles and took measurements on the way and shortly after refueling. As I thought the fans from the radiator reflected the remaining percentage of heat from the radiator to the foot well, my readings were if you can check my past posts on this issue over 100 degrees F down by your feet. Looking at the original MK1 cars you will notice that the diversion area is located so that most of the air passes through the nostrils. Ours does not. I got the nerve and with a air grinder, cut out the two boxed areas that where limiting the air to the nostrils. Formed up a scoop affair and then fiber glassed front and back sides. My wife and I took the car out for a ride the other night and she said "you know my feet are not hot anymore" she wears sandals. I think that that solved a lot of the heat sink into the foot well area and believe it or not we both noticed it was quieter. Crazy but seemed that way.
