Well, I count a couple of the Hemi failures as his directly.....A rev limiter on the one he missed a gear on would have saved that one....This one he just had to set a AFR limit. The Hemi design does not tolerate any over revs....You float them, you broke them. At his Hp level there are things he should be doing to protect his investment.
This winter, I plan on updating my Holley dash with more sensors & some limits for those sensors.
