Brad,
apperantly for PoBoy (if he is who I think he is) then with his setup, the block seems to be doing failry well. He says it even beats the maze 2`s performance. If I am correct, then he has a oil cooler sitting in a freezer with sub temp air blowing thrue it.
(I am not one to really down grade anything) Maybe this is the best use for this block. Pumping sub temps thrue it. With the base of the block being considerably smaller then the top, I amagine it makes it alot easyer to insolate the socket and the block, as you can get more foam around the base of the block.
It is quite possable that his pump size is also just right for the Z4 and was under powered for the maze2. Hitting the z4`s sweet spot with flow and coolant temp. I am sure there is a good use for every block out there. It just seems that the ambient temp crowd like ourselfs or the pelt crowd would have not use for this block. Other then a paper weight.
Try and find the good in everything. (Shoot the people who make U have to do this
)
