Well, we know MB left room with the SC so they had no recall issues but finding where the line is.........that's the info that would put many at ease and allow others to go for it. I have seen numbers that are quite high but nothing to back them up.
There is a chart that lists the different combo's in this SRT-6 forum. Good info at least it makes the numbers easy to check quickly. I think boost monkey is running stacked, I may ask him what he has found as he seems to do a lot of research, that is good of course. One thing that Jim(mid 10's) did say that made sense is that we do not stay in boost very long. I have seen guys post that they are running really lean in the upper rpm's and that is really scarry. Doesn't take long to melt or crack a piston, forged or not.
So it is the SC rpm right now. i will try steggy this week and see what he says and post his response. mark
