I have been flying the 4into1s for almost 8 years and 600hrs.  They do run 
close to the sump.  I would run high oil temps at first with only the front 
cooler, then I installed a rear, and never have any oil temp problems now.  One 
thing however, they do send all four pulses into the prop and leave residue on 
one blade.  With a three blade, you can't clock it not to hit one.  I really 
like the idea of the forward facing pipes.  It would prevent the residue and 
heat on the prop however I have never noticed any "cooking" of the prop or paint.
