I have done a few searches on the Crooked willow / mocal coolers and most people seem to think they are a good upgrade. I found great installation pictures and whatnot, but i would like to know how well these actually work. How much difference could you tell, or could you tell any? It seems like people are saying "well yeah it works great.....i mean i think it does.....well it seems like it would...." But no actual "YES, it dropped my oil temps 30 degrees or something". Can anyone tell me how well this setup actually works? Thanks for you time.

Maybe you should try getting ahold of Duane K. from CWR to see if he has any empirical evidence of how they work.
