Gents.... So I'm a newbie around here and couldn't quiet get a proper feedback by searching around here for the power potential of the stock motor/tranny.

Ideally, I would like to know what's the most one can expect out the stock motor/tranny without hurting them. Plus, How much boost does this thing run in stock form?

I'm planning on doing the deletes and a minor tune next season but would like to do my homework well in advance to avoid mistakes as this is my first Diesel. If there are anything else I need to keep a close eye on then please let me know as I'm a green pea to trucks/diesel/Dodge etc.

Please check out my thread in the general discussions for pics of my 12 DRW CC Laramie Longhorn.

 

Wow... Almost a 100 views and no response...

 

in my opinion the vgt turbo is the first weak link to power. most will not stand a tuner turned up beating on it without blowing a head gasket. the tranny also wont stand top tuning. keep in mind i have one with stock turbo and tranny. i run about a 100 hp tune and get along very well. i got several customers with suncoast trannys or dual discs and silver bullet 66 turbos holding good power. i got a customer with twins. i know the stock internals first hand will hold around 750. how long i dont know

 

I don't know much about the 68rfe ,but as far as the stock cummins 6.7 goes there are people pushing upwards of 850 HP on stock internals however there are many variables in that situation. One being your tune most off the market programmers bring fuel in down at low rpm which is very hard on bottom end parts. Now with the use of efilive we can tune around the stock bottom end and limit fuel so I guess my answer is depends on tuning you run. There really is no your engine will blow at Exxon HP. Im with tony on the turbo
