pretty cool, I found original dyno sheet from when velocity installed the sci 575 into my 280 in 2010. Since 2010 the 575 has only had a little over 100 hrs put on it.

I have 10k worth of drive guardians sitting around.
They cost me one vacation and one weekend when they burned up.
also a few weekends pulling motors to go back to a standard flywheel.
Also a few weekends dynoying the engine so we could dial them in on the TQ.

I know, the nutswingers will say they are the best and I really wish that was true, they are a fantastic idea, too bad they just don`t work.
I know a lot more people with the same issues.
Another one a week ago.
Mike left me hanging so I will tell my tale till the end of time.
Sorry , Not sorry.
