Racing battery question

Sorry my friend you are completely mistaken. You are most unfortunately NOT clear on the "affects of torque." The torque of the driveshaft is attempting to lift the right rear tire off the ground. The torque reaction of the engine in the chassis is what is "planting" the rear quarter, and your photo is proof you are mistaken. In other words the body, from engine torque, is trying to twist up off the suspension.

In the same way that a broken engine mount lifts the left side of the engine, the left side of the chassis is being twisted by engine torque

The fact is, if your car "hooked" really really good, you might have been better off putting the battery back in the left front corner!!

Battery placement on the left rear worked for me!

BTW, that Ford had ladderbars and coilovers. It could hook on dirt with those big tarz!!! :)
