DYNO DAY 14-07-2018
Today tested several ignition curve to find the best on.
Did a total off 32 runs with a outside temperature of +32 degrees (not the best combination for man and machine)
Think this has some influence on performance as well, but ended with a good 27,5HP at 10600rpm
Her you have the runs with 12 and 13 degrees at peek power.
Her you have the runs with 14 and 15 degrees at peek power.
Her you have the runs with 15 and 16 degrees at peek power.
Here the best run with 14 degrees at peek power.
The Difference between 14 or 15 degrees is minimal, so for safety I used 14
Always interesting to know how it shifts through the gears, peeking at 27,3HP is not bad
And how does that sounds
And final the difference between:
Stock engine + 4 degrees oem ignition VS. Stock engine + O-ring head and Zeel
Corrected the old run to the new dyno setup (without starter as that was not pressed at the time)
The 4 degrees more on a oem CDI makes the ignition point at peek power the same.
See green curve (+4 with oem CDI) vs the Red curve (the zeel)
The higher mid section on the zeel and higher compression gives the difference of 1,5HP
But comparing like this is difficult as weather and temperature do play a role
Note: Red curve is the stock ignition +4 Yellow is the Zeel
