NEED FEEDBACK: DPF Retrofit on Detroit 60 Engine - Good or Bad?

pros: anytime when dpf clogged you can remove front clamp to have pressure dropped and can drive to repair place. its not connected to engine ecm and anytime you can take off the whole system.
cons: lower mpg, short dpf cleaning intervals if you run colder(Midwest, northeast, , northwest) states and medium to light loads. dpf's with active regeneration will solve this issue but its expensive.

 

The non-ecm DPF units you can have a light added to your dash. To let you know when to have filter cleaned.

Its big business in Cali. They have been cracking down on "non-authorized" installers.

For what its worth, I have personal knowledge of. 2000-2003 trucks 2004-2007 running retro-fit.

Avg. Is down to 3-5mpg and then the 3-6 month interval of $700-$3000 to clean or replace filter.

Good luck hand.

 

I have done the retrofit, BUT, its on a Cat engine. I can not speak for a Detroit. Mine has work extremely well. Fuel mileage has been averaging about the same. The only difference I have noticed is the EGT's run about 100* warmer the way I drove it before the retrofit, But when I raise the rpm's, the EGT's drop right away. I basically had to adjust to where to keep the rpm range when the engine is working harder. Im also not running a stock engine, the flash file, fls/fts and turbo all have been change. BUT meets CARB guidelines. The OP keeps mentioning about testing to see if his Detroit engine can handle a retrofit ? I answered this either here on a different thread or forum, I cant remember, anyhow, I don't know of any test and never heard of a test that can be done to see if any particular engine can handle the retrofit. When you go to a certified CARB shop, they are going to install a data log probe in your exhaust to measure the heat like a pyro and will record it for 2 weeks or so. That will determine what size filter you will need and I can tell you now, its gonna be an R-40. Your looking around $15,000 to $16,000. Beware of the quality workmanship. Just remember, you will always get what you pay for.

 

if you are doing it to run calif you need to go to the CARB wesite,,Calif will only approve retrofits done in authorized shops,,I would not do it,,the cost is too much for just a few more years of running in Calif

 

if you are not calipornia intrastate carrier forget about retrofitting. Sell the truck and buy epa07 or epa10 if you can afford it.

 

Sure, go ahead. The truck will see more time in the shop than being on the road. I see these trucks on the side of the road ALL DAY LONG. I would gamble on the retrofit any day, specially if you already know your truck.

 

Dave I did it last year. I had 05 century with 900k miles on it. i have epa10 dd15 now. i have driven 110k miles. the truck was in shop once for radiator warranty replacement. on this period i have changed the def doser and plv.. all together less then $1000. i am happy with mpg and it actually saves $700-800 monthly wich is almost half of the payment. the truck now has 382k m and the dpf was not cleaned yet. i don't keep trucks after 1.000.000-1.200.000 miles. it was senseless to pay for retrofitting for me, i drive around 130k yearly.
