You did a dyno pull from 100mph-140mph? Why isn't there any RPM's on that graph? Kind of hard to tell what is going on there. Just HP and no TQ?
I've seen a couple 6.0's shift into overdrive on the dyno and run out to 140mph, they were screaming on the dyno. Gets a little scary being near that with mud tires on.
I hear you on the compounds and if you're trying to stay in that class I suppose it makes more sense. I've always been a little skeptical about the reliability of those 71mm VGT's, since they're mostly built off of a powermax frame, so they have a huge compressor wheel running on the same bearings and center section that was originally designed for a smaller 63mm or whatever the p-max is. I'm interested to see where this goes! Keep us updated.
