I recently installed a 5" turbo back dpf delete on my truck, and it increases the horsepower noticibly... But how much did it increase it? If you have Dyno'd your truck before and after a dpf delete, please tell me the results.

 

Just the delete alone is only said to gain about 15 hp but about 85 ft lbs of torque.

 

the day after i did the dpf delete, edge juice with att+ hot unlock and banks ram air i was at Edges facility and dynoed mine during their dyno day in september "weekend on the edge"....iwas the only 6.7 there and the only dually...they were shakin their heads and whatnot when i pulled it in then when they saw the numbers, they had a change of heart and was then noddin their heads...it put down 387 hp and 722 ft lb...not to bad with 3 small mods and a hotshot truck...ended up placing 8th out of 32 in the class..i kno it aint no huge numbers like alot of the guys, but it impressed us all...never did dyno it stock, but ive always heard, u lose around 100 hp and tq thru the driveline...i dont know the exact numbers behind that, but i kno u do lose some.

 

I remember reading and article in Diesel power and it had a 5.9cr (i know not what you're looking for) that dyno'd stock at at 289hp and the engines are rated at the fly at 325 so i think it really depends on what kind of dyno a guy uses and one persons results aren't gonna be the same as another persons results

 

the one that EDGE was using was a "mustang"...thats what my printout says

 

I did dyno my truck CC factory rated 305hp/610tq before and after. Fist dyno stock truck with the egr unpluged was 281hp/560tq. After the dpf delete 296hp/567tq Add the hypertech max on stage 3 373hp/733tq all done on the same dyno. Dyno jet with 25% load. I tried dynoing in drive and T/H and O/D locked out for my original stock 281hp and in all three gears the #'s were almost identical just had trans shifts in the middle of them. Ended up useing T/H from about 2,400rpms to red line for the later runs.

 

Quite a bit of power can be gained from a DPF delete. A typical muffler system has 1-2psi of backpressure at most, a DPF has 3-5psi with even higher pressures if it becomes clogged.
