Bob,
The 4BT powered truck that was in your shop when I was there did not have an aftercooler. The customer complained about a lack of power. You mentioned that an aftercooler would really help. You were right. Would a front mounted intercooler be better? Yes, but it won't fit in the truck. I think the original owner of that truck was actually told by Cummins that it wouldn't even run down the road without some kind of air to air cooler installed. He didn't put one on and it ran for him but not anybody else.

It seems that you are talking about stuff that will fit on a stock bodied M715 and others are talking about '07 vehicles. Big difference in size and money.

I for one was not trying to argue with you. I was just injecting in a non biased way what little tech I actually know about turbo diesels into the thread.

Now, about your original question that started this thread. A 6BT has been put into stock framed M715's before. Body lifts were needed. Somebody posted a link a year or so ago of a Japanese licensed copy of the 6Bt that is shorter and fits better. I can't find it, but this same basic discussion resulted with the same basic comments. If you want to stuff a 6BT into a M715. Do it! Will it run with a 2006 Dodge? No, but it will do better that a 4Bt and be unique.
