Just an observation from yesterday with a temp of about 73 deg. versus a couple of runs a while back on the same dyno with a temperature of about 66 deg. nearly the same humidity.
Comparing runs at 22.25 deg of timing to runs at 26 deg of timing, the power level was up on the higher timing in the following manner.(gov springs were also tightened 2 additional clicks).
start at 80mph(rpm numbers are approx).
2100rpm-equal
2250- +35hp
2385- +125hp
2500- +150hp
2650- +200hp
2780- +225hp
2915- +200hp
3050- +100hp
3180- even
Your results will vary, but it gives an idea of the change in power under the curve from the timing change.
Another thank you to Chris and Jeremy at Jefferson State Diesel for all their help.
