Unfortunately, one of my specs s to use what I have on hand, so this is what I ended up with
I did away with the input current controls, they kept if from running, and then after that, it didn't seen to matter what the inductor was, all I could get with a ~100 ohm load was `67 volts and ~700ma, I wanted 800 ma.
Then I changed the load to ~50 ohm and I got ~45 volts and ~1700ma and it didn't seem to matter which inductor I used, from 200uh to 8 uh, same voltage and same current plus or minus, but it's good enough for what I have to drive. But if I can't get the 87 V and 800 ma ande have have to settle for driving 2 sets of LEDs with on driver, I guess I'll see if I can drive 4 strings from one driver and use 4 LM317s, probably go with a LT1270A.
I ran 7 amps through the FET, Vsg<10, and had a Vsd of 1.6V and 6.9A through the diode gave me a drop of 1.06 V.
Because of the heat generation, I found the use of an old hair dryer with it's 3 winding of 50,30, and 20 ohms very handy, especially with it's cooling fan.

PS Thanks for your help, apparently, I am trying for too much boost.
