But I think a lot of the zoom zoom boom issues related to the DISI platform might have been tolerance issues, which would explain why some can handle tons of power and some blow bone stock. If you're one of the unlucky ones with fragile rods you may blow no matter what you do, but it could be just a few that made it out of the factory with slight flaws that weren't noticed. I don't know. There's a 100+ page thread over on MSF where people try to figure out what causes the zoom zoom boom and I don't know that anyone has ever come to a conclusive reason for all of them.
People were scared 6 months to a year ago. There are many cars at the low to mid 400 range now and a couple getting close to 500whp. There is also a built motor MS3 that put down 540 whp. So far there hasn't been a single blown motor from hitting to much power. The road block now is fueling. Realistically 420-430whp is the outer limit to how much power the injectors will push. My injectors are static in the upper rpms on 75% E85. The torque is epic and I honestly would not be surprised to see my torque dyno in the upper 300's uncorrected. There are guys even running 100% E85 on the stock fuel systems putting down close to 400wtq on the stock k04. The platform has made huge strides in the past year. This summer alone saw a ton of BT builds. I think there were 3 or 4 in Colorado alone.
I believe the rod issue was one of a couple things. Either it was factory defects that ran its course, bad tuning, or ultra high tq loads at low rpm from the K04. If the MZR rods were the weak point across the platform the blown motor thread wouldn't practically be the ghost town it is now.
