MW IP Modification / Tuning

[OM616]

I am officially on my own job wise and I am testing the waters. If this is not the correct venue, I sincerely apologize.

After tuning a few 616 NA MW IPs for on and off road use, I am considering building a rig to set up and bench tune MW IPs with RW Governors. This would include changing the Elements to larger ones, changing Governor springs, and individual Governor settings to meet the owners needs.

After looking into this for a while now, I am disappointed but not shocked, by the loose tolerances of the settings that are considered OK per the factory.

Without getting into detail how I would build my rig, all measurement tooling would be certified, Element shims would be custom ground to achieve the finest degree of accuracy of the start of injection between cylinders. Fuel delivery quantity would be measured mechanically, (hydraulic cylinders with dial indicators), as apposed to graduated pipepets.

I would also put on my, (wish), list an engine on a dyno. I have an engine dyno, but it is set up for something else, so I would have to build a new test stand and then get a good engine.

If I were to do this, I would first build up an IP and take it to an independent Injection shop for verification of the settings. If any shortcomings are identified, I would take the necessary steps to address any such issues in order to achieve as close to perfection as possible.

If I survive the beatings that are sure to come, I will figure out potential costs.

As always, your thoughts are encouraged.
