Not sure why
@DNasty777 would disagree with the video, I find that funny. I was impressed by the amount of torque the stock stuff held up to also, and I kind of agree with the rod bolts being the source of the failure. That’s if I had to pick one thing to blame it on.
@Icetech almost any stock engine will take 5-6 pounds of boost for a long, long time and be perfectly fine, IF you put a little ring gap in it and keep the tune up in check.
