Got a trouble code? Wondering how to get your engine to make more power? Our Top Tech section is a place where you ask what’s on your mind, and we answer it.700hp Tow Mule

Question:I recently purchased a 2012 Ram 2500 with a 6.7L Cummins and want to make it stronger, faster, better...you get the idea. I am not new to the mechanical world, as I am an automotive technician, but I am new to the diesel world, and this one is my first. I was wondering if you guys know of a tried-and-true setup on the 6.7L that can get me to 700 rwhp but remain reliable, as this is my daily driver. It’s not going to be hot-rodded, but it does pull my work trailers every so often. Now, I understand that as power increases longevity will usually decrease, but what kind of things can I do to get me to this power level? And which parts will need to be replaced to increase longevity? My point is, I don’t want to be dead in the water at 100,000 miles. I also understand that parts can be quite pricey, but for the sake of this letter let’s assume price is not an issue. I would also like to keep the variable-geometry turbo in a compound setup, as opposed to a large single turbo. I have already installed an S&B intake, 5-inch Flo-Pro exhaust, and H&S Mini Maxx, and vented the crankcase to the atmosphere as opposed to the intake tract. So what can you tell me?
