The coolant from the heat exchanger on the cold side is directed through the front drive casting - not associated to the oil reservoir - then said cool water moves front to rear contained by a made cavity heli-arced into position. Water then exits on the return side of your aftercooler to be re-cooled and recirculated.
Blowers with shorter drives use a second patent pending design that circulates water in a 360 degree arrangement.
Thank you
I like the gains of this design and if your going intercooled tapping into the lines there would be so easy... but is Coolant really a good idea going into the casing??? I mean coolant vs supercharger fluid... really?

Or am I way off base and the snout hollow and your simply tapping into that area? Just curious on the idea, I would think coolant in the snout would be dangerous to the seals and stuff.
