Nick,
  Your coil will not process that much power. At best maybe 500 w. My 4" 
/ 110 mm coil will not process power beyond about 5 Kw. The 6" 
155 mm will take a maximum of 7-8 Kw. Your maxed out. I'm guess what I'm 
saying is that you need to cut the power levels about 90%. How much 
power will you get with a 30 uH inductor ?
