MPD's "Project 6.0L Proving Grounds"

Awesome project guys, nothing to add that hasn't already been mentioned.:thumbsup:

So in the end innovative was top power by 1/2hp to gearhead. Power curves looked almost identical. TSDs tune made a best of 321 after 4 different pulls. Each pull was made from 70-120 no brake spool

How long for cooldown between runs?

Mike@MPD · Nov 22, 2013

About 10mins

Also just a suggestion, I would bring something to clear the KAM between programmings and do at least a 1/2 throttle run through all the gears before hitting the track. It will probably save you guys some frustration since all the tuners do the trans tuning a little different.

F spending time/money on ext. This is a underhood build. Nobody cares about the results on a paintjob.

You shut your mouth

I would say the dyno is about 80hp off. We will find with track times today

Awesome results so far boys....eagerly awaiting this

It's never made sense to me why the KAM does not get cleared when tuning a vehicle.... Maybe it would freak the customer out if he didn't know to expect some irregularities right off the bat?

I guess they're not so great spooling after all.

Exactly haha! People claim great spooling until you put them through a real world converter locked situation!

This is SO true...

Someone had to day it.. Lol

One thing I would love to see monitored during the testing is fuel pressure at the upper filter housing, or near where it would be if/when that gets deleted. Starting out with new, or near new filters so everybody knows not go blame the filters for lack of flow, do some wot off idle runs through all the gears, and record the lowest pressure seen. By doing this with a stock fuel supply system, everybody can see the validity of a fuel system once you work your way into injectors that pull below safe supply pressures even with the "blue spring mod". At that point, dynoing it with stock fuel supply, and then after it's upgraded to whatever you decide. This is a test I would love to see. I suspect a lot more people will be buying fuel supply systems once people can validate and quantify gains over stock. I know on my '04 with 155 cc injectors I saw Pressure drop down to 22 psi at the filter, and I'm wondering if my results are atypical. I never put an upgraded supply system on it aside from the 6.4 banjos and 71 psi idling it had at the test. (I stretched the stock spring rather than buy he blue one)

Such a great one to test.

Seems like the 6.0 fuel system is almost as bad as the OBS system

we are going to try and monitor fuel pressure as best we can, with the blue spring upgrade and 6.4 banjos... then we are going to put the regulated return on. The downfall is the factory regulator, the stock pump if healthy should give us all we need for what we are going to be testing.

Wayne · Nov 22, 2013

As long as you have a gauge, you will know. I wonder if part of the reason my pressure dropped like it did is because of the increased flow from the 6.4 banjos. If your testing goes anything like mine did, you will need pre-regulator upgrades after the stock injectors get replaced. My problem wasn't the regulator, it was the supply to the regulator. I am certainly looking forward to your findings no matter what you test. I love threads like this where everybody can learn a little something.

Derek@Vision Diesel · Nov 22, 2013

A truck with 155/30, regulated return system, and a factory pump with 6.4 banjos will not hold pressure..... at least here in Oregon they don't haha.

Doesn't seem like a regulated return system makes much of a difference on the ability to maintain either, but it could be we are dealing with weak pumps or something?
