(02-24-2015, 01:35 AM)Captain America(02-17-2015, 12:35 PM)OM616 How much did you advance the timing after the PC mod?
So in an OM617 as such mine, what would you set pump timing to with the huge chambers that I have? I have the timing max advanced but have not re-clocked the pump yet, but sounds like that is something I should do? I can get to 1250 but not urgently quick on the street. A lot of off road hill climbing, second gear foot to floor, 2600-3000 RPM full load 16lbs boost and EGT will sit at right about 1200 degrees
I was lazy and did not re-clock the pump, so I am at the stops as well, (how many other people can say that lol). When I pull the engine down I will measure what the start of injection is at the stops. I am going to be installing 10mm elements in the pump and reworking the advance mechanism, so my new timing demands will be much different.
Timing is specific to every engine according to how worn it is, the quality of fuel, the quality of the injection, altitude etc... The only "speck" that is worth anything for any engine tuning is the static timing so that the engine will start. Once running a tuner will find what the engine wants, (runs best at). This will no doubt have the engineers screaming at their monitors that you must be with in X degrees regardless of all the variables that affect combustion.
If you are happy with how it runs now, then leave it. If you want to see if the engine will take a little more advance, then recenter the pump and find out. Even at the stops, we are way more advanced than the general public lol...
If the engine does not like the additional timing, it will get hard to start cold, be naily, and not run as well as the previous timing setting. In that case you have found the limit and go back to the previous timing setting where it ran the best.
