The third battery box is nearing completion. It fits between the firewall and the motor and will hold three batteries.













Clutch & Flywheel
Due to the high torque of the electric motor a clutch upgrade is necessary. The middle column is the old clutch from the crx. The right column is the new setup with the six puck clutch and the chromoly flywheel. The column on the left is from my mustang cobra. You can see the difference in size of a 300+ hp clutch and the 103 hp.

I recently swapped out the clutch and flywheel in my cobra with a King Cobra clutch and an aluminum flywheel. This was good experience as I got to feel what difference a lighter flywheel and stronger clutch make. It will be interesting to see how the electric motor changes the feel as well.















OEM clutch and the new "Stage 4" clutch. This is one of the highest friction clutches that still has the torsion springs.














This is a 2012 taper lock bushing and weld on hub. It will be used to attach the motor drive shaft to the flywheel.

Closeup of the flywheel. The chromoly flywheel is significantly lighter than the stock flywheel. The lighter flywheel should improve efficiency slightly. It was also chosen for its weldability. The six bolt holes in the middle would normally bolt to the crankshaft of the ICE but in this case they are conveniently placed directly over the two set screws in the taperlock hub. The only problem here is that after the hub is welded on there is no access to the third hole in the hub. The third hole is used to disconnect the hub. This may required drilling a hole in the flywheel to remove it.
