When moving the Necam Dizzy & Stepper Motor you'll want Proper Hose
In no particular order, as I think of these pointers, here's what i mean by proper CNG / LPG grade hose.
NOT heater hose, fuel hose or that orange stuff!
Big Bore vacuum cleaner hose or heater hosing
It would do lot of good to direct a bit of old vacuum cleaner hose at the stepper too. Else, some big-bore heater ducting? Whatever you have really... why?
Fixed your ducting to scoop cool air at the stepper. Then the stepper is cooled much like the ECU in its own box. See the big square box, opposite side of the engine bay to the battery, with its own scoop? You want something to replicate that.
I have repaired Necam stepper motors, I'm an electronics engineer and I do a mod to these to mitigate the overheating problem and beef these things up a bit. Yet, there's nothing to beat keeping the electronics cool in the first place. I will show you pics if I can dig these out. But you get the idea.
