Coolant Pumps & Pipework

This is still a work in progress, but I’ll show how I mounted the 2 Bosch pumps.
Each pump is variable speed, 100hz PWM.

4 aluminum tubes run the center tunnel, 1 pair supply the motor cooling, with another pair being used for the battery cooling.
All other heat devices will eventually be housed in the front area.

Mounted the pumps by the lower front firewall, here the pump discharges have a direct shot to the rear of the vehicle, into each of the supply lines in the center tunnel:
Pump Mount 3D printed (Final version was printed in a CF ABS): Mounted in car: (Sorry unable to rotate)

Other 3D printed items:

Since I basically closed off the full engine bay, the previous side scoops dumped directly to no-where.
Easy fix was to 3D print some adapters, and duct the airflow to the rear brakes.
Print was broken into several parts, glued using acetone.
Material is CF-ABS, printed with 100% fill. Ends up being ~3mm wall thickness.
Mounted onto existing duct pieces, just trimmed to give a flat service to adapt to. The new duct pieces are glued onto these pieces using Sikaflex adhesive
