tuning and Trans issue

[QUOTE="Morgan@Midwest Diesel & Auto, post: 1155724, member: 8143"] The engine is 440hp at the flywheel. Which translates to 370-380 rear wheel hp depending in the dyno and tire size in a bone stock truck. The Trans is designed to take what ford tunes to engine to put out. Sure they over build them to some degree. Usually 10% by rule is what I've heard from other ford engineers. Still doesn't equate to holding at 550-600 rwhp. Which would translate to roughly 632-690 flywheel hp using the known drivetrain loss percentage we've seen from stock. Yep No, in this thread and pretty much everywhere on this whole forum we are talking RWHP numbers unless stated otherwise. Yep, I've had others last really good like my 2011 crew cab with the s366 on it that I beat the crap out of at 520 hp for nearly 10k miles till I traded it in. But my regular cab 2wd didn't last 1k miles at less hp and weight. Both ran h&s files basically the whole time I owned them. It is what it is. The 6r is an awesome transmission. But nothing is unbreakable. I get calls all the time inquiring about transmissions from all types of 6.7 owners with all types of tuning. Be surprised really. Especially growing since these trucks are getting miles and years on them now. Sent from my iPhone using Tapatalk [/QUOTE]
