Lol, I just read the comments, hilarious. Most of the people have no Idea what a 6.4 F350 fuel economy is lol. The comment sections always turn into a shit fight.lol
Sorry missed the update question. The Detroit 4-53T has been running great and just did a 4000 mile inspection and tune up. I really wanted to address my egt's that were 1050. So I retarded the injector timing from 1.46" to 1.484". I also adjusted the fuel modulator so there is no smoke on start and acceleration at low boost. I sealed up my cold air intake as there were some gaps allowing hot air in. After that the max egt's are now 945 and I picked up a little more power. Engine runs awesome and pulls hard right down to 1600 rpm. Just finished a 13 hr towing trip and it ran perfect. Here's some tube videos.
Thanks for the reply. So does it have the 4 valve head? I thought that was part of Silver Series? I have limited Detroit Diesel knowledge.Hi Randy,
I've got this engine tuned to about 200-210 and somewhere near 450 FTLBS of torque. Max HP is at 2500 rpm and torque at 1600. I converted it to a Silver Series with a performance cam, bypass blower, compound turbos, and 7A77 injectors. Truck weighs in at 9200 lbs and is attached to the Ford 5R110 with .71 overdrive and 3.73 gears. Cruises 70 [email protected] rpm and the fastest I've gone is 90 mph. Get 18 mpg hwy, 13 city. The 4BT is a great engine, I have a fair amount of time on the 6BT as I owned one for 15 years before it sadly got totaled last winter. One of my favorite engines. Merry Christmas.
Thanks, it sure is a pleasure to drive. Yes it has the 4 valve head and to make it running a Borgwarner K27 and K31 to help with performance. In the future I'll upgrade to either larger injectors or add propane. I'm build a 3-53T as a test engine to run an Ingersoll Rand 375 cfm compressor and will be running propane on that to see how it responds. If it's a success then I'll put it on my 4-53T as well. I have lots of room to grow more power, so I'll take it in small upgrades. I have the airflow to easily go to 300HP, but will stop at 250HP and call it good.Thanks for the reply.

It appears that most diesels are happiest operating in the 2000 rpm range. We are running 75-80 mph on the Freeways down here and my VW Touareg 3.0L Diesel is running 2000 at 75 mph. Getting 26-28mpg . The Jeep with 4.10's and my OD only being 22% I had to make up for it with massive "Mexican Overdrive" IE: 37" tires. All my numbers were based on the numbers of my 95 Dodge Dually, and turned out to mirror that almost word for word. My engine was a Bread Truck Motor (CPL858) and is set up at 105HP/275 FTLB. I was lucky and got a motor that was a Cummins Recon with 82K on it. It is tight and runs great, no oil use, but I would love a turbo that Whistles like yours does. Maybe down the road. Like yours it should last forever in both these light duty applications.
Great piece of machinery you created! Should return alot of satisfaction for many years to come.
