The borgeson did run a little hot but i think would have been fine without a cooler... I did add one though.. ended up around $40 and 30 mins of work. not a big deal.
I mounted it here to keep it out of the way..
.
for me, not having to cut my steering shaft was a big thing... plus i don't see how borgeson using a ujoint is any less solid (and noise transmitting) than the BAC coupler...
