Imo a good portion of 2.9 issues were from install and/or user error. They don't like being over spun and they don't like a ton of belt tension. They are a 18,000 rpm max unit, not a 23k like an Eaton. They like the tensioner in the middle to 3/4 max. The 2.9 is closer to a Mag 2300 but with larger cooling bricks. The 2650 can be pushed a lot harder which is why it became the go to. The 3.0 is about 5 years late on this platform. But they have very good cooling and are fairly efficient. I have had a 2.9 for almost 6years with no problems. If I wanted more than 15-16psi, I would move to a 3.0. The 3.0 also makes more power at the same boost level. About 30-50whp more.
