I know we've discussed this in person, but I wanted to ask this so someone else can see the answer if they were to ever search for it.
In your opinion, at what point is the looped rail necessary on the SRT motor? Stacked pulleys? Manis? A specific PSI of boost? Or is this simply a good "insurance" mod at
any level of tuning?
