I was at one of my car get togethers here in Michigan, and was informed that the Crank in the new 6.4's will not hold any boost, and that Chrysler is working on making a boost happy engine by taking the crank out of the previous generation 6.1 creating a 6.2. Has anyone else heard anything like this?

One of the engines they are testing is a S/C 6.2L. There are some 6.4L running boost right now in some Challengers. How long they will last is the unknown but I heard the problem was the heads.

Yes. And then you blow up your motor. Sound like fun ?
Have you heard of this happening yet? How many 6.1s met the same fate? Seems hypocritical.

Aren't the 6.4 cranks forged? That shouldn't be the weak spot. If it's like the 6.1s, the weak link is still those hypereutectic pistons.

Procharger and Vortech as well....it'll be interesting to see where this goes.

So this will be wildly disappointing as my plan was to buy a 2012 in about a year and a half and supercharge it. The CTS-V is starting to look more and more like my next ride.
