Third motor mount
I’ve been using some stock Volvo 544 mounts to keep my engine in place in my 71 volvo 1800. I’ve been using these particular mounts because they have an approximate 1″ thickness vs. the stock mounts 1 3/8″ thickness and give me hood clearance needed by the supercharger. Over time, the amount of torque and traction produced by the car is a bit much for this design. Autocross starts are 4500 rpm clutch drops on race tires and a sloppy downshift on a road course can transmit a lot of energy to these mounts. Recently one of the mounts let go and sent the forward edge of my compressor into the sheet metal of the hood. This sucked, time to fix it.
