Trunk Mount Batt. Opinions needed

I'm assuming the CD relay is a normally closed relay setup like Oldmanmopar has to shut off his alternator during racing.
The only reason I shut the alternator off when racing is to prevent the belt from coming off from resistance when charging. When shutoff there is no drag on the belt. shift light set at 8000 and My engine has seen RPM's up to 9300. The belt and alternator couldn't take those RPM's while charging. All I did to move my battry to the rear was to run a cable to a bulk head in the front that acted as my battery under the hood. All the original wiring and the starter relay was kept under the hood. The bulk head was my positive cable. I used a solenoid to kill the alternator.
