Hi Charlie,

If you increas the inverterfrequentie, your max rpm will be less.
With the *normal* values, the max rpm is ~140 Hz (=60x140=8400rpm)
If you speedup the iverterfreq of the coil to ~180Hz, the max rpm will be 60x180= 10.800 rpm.
BUT......if you speedup the inverterferq of the coil, you get less current to load the capacitor for the spark.
Now you need more voltage to evaluate the current you lose.
I hope you understand wat I mean to explain.....In Dutch it's muts easyer to explain this ;o)

BTW(1), I get my mail to you back....5.1.0 - Unknown address
BTW(2), You can send me mail now, rr.com don't block the mail anymore.(I hope)
