clutch drive fans

i get what your saying but as said mopar muscle says that up to 15 hp at the rear . i dont think its that much but i think that it suppose to be some....and as a side note once at the track my belt came off in the burnout box and i didnt know the car went just a little faster mph and et no very much but did...now the fan is suppose to only work at its full pot. at a set temp. and to a base rmp so id say you should gain something along the way...as fro as thw water pump drive on a street car you know what they say street car is used loosely..i drive my car maybe 10 miles every 2 mouths....but even when i drive it and go off and kill it a few times it never get over 180 even with back to back runs at the track with no cool down time between.....
