Modifying Fan clutch

ok guys, ive been doing some research, and ive found that the stock fan clutch dont lock up untill the engine is really cookin hot. well with this turbo and crap goin on on my engine the coolant temps get warm and the fan clutch isnt locked. i dont want the engine temps to get to 230*F before the stupid thing locks up and cools it off. so my question is how do you modify the fan clutch so it locks up around 200-210*F? also other than the lube specialist kit, what would you guys recomend for a aux oil cooler for the engine? because more than once ive had to stop my fun because the oil temps hit 220*F.

go and look on sls's thread '' my biggest fan and the snake, someone posted a clutch fan mod on there, think it was d.camelleri, he said to make a different slot for the tension on the spring, so it would engage later or sooner.....

Just went out to the garage, hit the spring with the propane torch, and it rotated the shaft counterclockwise. So if you made a notch just to the left of the current notch that would make the clutch engage earlier. You could probably make a notch every 3/16" and have an adjustable clutch.
Acesnights also suggested "tweaking" the spring to get the same effect.
