Been there, done that, at least my car has, I wasn't driving it went it sploded....I will keep my CSR shield on unless somthing better comes along. He was very lucky....When they do go, they go big...I think the newer bolt in sprags will help keep that from happening, but I would rather not test that theory.




Knowing the right way of racing a 727 helps too.

I would be willing to bet that 99% of the ones that let go could be traced back to either driver error or a part failure in the driveline that should have resulted in a tear down and inspection that didn't get done.

I see way to many people where they are backing up and slap it in drive with out stopping, or have a motor that idles way to high and dropping it in gear getting on and off the throttle in 1st, doing a burnout and then putting it in N to clear the motor and not rolling the car far enough forward to re load the sprag ect ect ect.

But we always blame the unit. Flame away
