Why do they always have more power?? is the 6.6L that much better then a 6.4L Or is it because it has been around for 5+ more years then the 6.4L So they have more to off of and they have better aftermarket supply then the guys with the 6.4L??
see the red. budget has a lot to do with it. Most people know. and are comfortable limits of their stuff. If a motor like Clausen's blows up, it's 10's of thousands of dollars to re-do properly. That's more of a gamble than most people can swallow. Don't push it beyond were you know it will take the abuse, unless you're ready to suffer the consequences. Custom Auto can't use that kind of power on anything but the dyno anyway. Sure, it's a super fast truck, but it doesn't run 8's last I checked. All it is, is just hitting a big number so people can go "ooh, ahh! I'm so jealous". What they don't realize is that at that level, blocks break and crack, crankshafts, and all kinds of super expensive things can break, and go wrong.
Last year, Erik's stuff was at the safe limits of the bottom end of his engine. If Erik had left well enough alone, he'd still have an awesome daily driver, but not something that could comfortably hang with a truck like custom auto's stuff. I won't list off everything that Erik has changed to make it more reliable and powerful, unless he wants, but it's pretty much everything reasonably possible. I still don't expect deep 4 digit power, or 10's, with that weight, but it's still a solid truck, built around how he uses it.
