My suggestion that you need 2 torque limiters is from a data collection of 24+ years running high speed road course laps [130mph+], 4 days per year, 140 laps per year, 2.5 min per lap. 2.5 min is very respectable. How many 1/4 mile passes does that equal?

140 x 24 = 3360 laps x 2.47 miles per lap = 8,300 miles x 4 = 33,197 1/4 mile passes.

2 cars, 1 small block, one big block - same problem - compressed right side mount; right side TTI header collector pointing down under large throttle load, right side muffler straps at the muffler tear, the motor is not level side to side at rest.

Please note the right side collector in the attached picture for photographic evidence of the phenomena.

Maybe now the picture and math will help make sense of why 2 torque limiting devices are required not a luxury.
These devices cannot be a rigid mount, there has to be a degree of give to isolate the engine vibration. I promise never to come over here into your playground again.
