    2016 Cumins Turbo/Actuator failure

    $6K? :oops: We sell just the actuator at work for $1,700. I replaced my factory turbo with a more powerful and reliable fix geometry S365 and performance manifold for $1,600. Did the install myself and was fairly easy other than lifting the old turbo and manifold out of the engine bay while...

    Need advice on picking a truck

    My statement from long ago was based on the average 1,443 users who logged tens of millions of miles of fill-up on Fuelly.com. Around 22 mpg still seems to be the average. Since writing this post from 2018, I actually purchased a 3.0L Ecodiesel Jeep Wrangler Rubicon. On the back country...

    Normal coolant, oil, and trans temps.

    I purchased a Jeep Wrangler Rubicon Ecodiesel late last year and have been surprised on how much higher it's temps are compared to my Cummins. Trans is 195-200F, oil is 215-230F, and coolant is 205-225F when I am goin 70-75 mph down the highway, unloaded. It has 35x12.5 Nitto Ridge Grapplers...

    Fuel Mileage

    if you put larger than stock tires on, make sure your speedo is calibrated to your tire size. If it is not, then both the computer and hand calculations will be wrong. According to Fuelly with hundreds of 6.4L owners logging millions of miles, your end of tank calculation should be around 12...

    Start out hesitation on 2018 6.7L 3500 when cold

    Hesitation as in it waits for the grid heater to warm up before starting or hesitation as it makes a loping sound(like it has a mild cam in it) until it warms up? In regards to the lope or surging idle, I have two tunes for my truck from two different tunes, Hardway Performance and Anarchy...

    tie rod ends?

    The front suspension of the HD's changed from a 5-link setup to a much stronger 3-link system in 2014.

    Transmission Question

    :oops: 225 psi on a stock valve body! Holy Hell! I am surprised that the separator plate and gasket in the valve body lasted longer than a few thousand miles with 225 psi.

    Transmission Question

    I would have your brother get with his tuner to send him a 225 psi line pressure tune. He might have to pay a hundred dollars or so for a tune change, but all those expensive parts would be worthless without increased line pressure to hold those performance clutches together.

    Transmission Question

    Line pressure constantly changes from 90 psi to to the max numbers below depending on how much throttle you give it and current gear. In stock form, max line pressure should go up to 160 psi. If it is tuned without an aftermarket valve body then max will likely be 170 psi. If he is has an...

    ? Tire mileage

    Had Nitto Trail Grapplers that only lasted around 30k miles. Replaced them with Nitto Ridge Grapplers and got 60k miles out of them while never rotating them. Very quiet on the road for how aggressive they are. Have about 20k miles on my second set of Ridge Grapplers.

    3:73 to 4:10 cost

    Correct as far as peak HP and RPM, although I forgot the HO has torque of 1,800. That changes the amount of HP generated at peak torque. I was just doing the math on the HP these two generate at peak torque. (Torque X RPM) / 5,252 = HP at said RPM (850 lb-ft X 1,700 rpm) / 5,252 = 275 hp at...

    3:73 to 4:10 cost

    From the engine dyno released by Dodge back in the day, the 8.0L V10 does put down more torque and therefore more horsepower of around 250 hp at 1,700 rpm than the 6.4L. Max torque of the 8.0L was 450 lb-ft at 2,400 rpm which is really low for a N/A gas engine. Torque generates horsepower and...

    3:73 to 4:10 cost

    The unfortunate thing is that while shorter rear gears will give you more torque to the wheels, it will not give you more horsepower which is what dictates how fast you can go. The 6.4L does have a lot of horsepower, but like most N/A engines you don't a lot of it at rpms down low where you...

    3:73 to 4:10 cost

    True, but I don't think many get a diesel just to save money just like many Challenger R/T owners didn't get the V8 over the V6 to save money or the F150 Ecoboost owner didn't get the turbo 6 over the base V6. Those engine options will cost the owner more and more over time since they use more...

    3:73 to 4:10 cost

    $4k dollars? :oops: You might as well get the diesel if you had to do that. I don't think you will get even 25% of that $4k back on resale, however, you are more likely get up to 90% of the $8k you spend on the diesel back on resale.
