Tubomolecular pump synth thing


I have been playing with a sample I took of a Varian Tubomolecular vacuum pump in the lab at work. It whines away at 75k rpm persistantly but there is some structure and layers to the sound so with a little attack and delay, a touch of filtering and some reverb it sounds like quite a nice synth pad to me. The question I have is what do those with more trained ears and experiance suggest for tweeking it to get the most from it?

I have added a few layers of processing to it and a couple of knobs to adjust the sound to suit. I think its getting better, any feedback much appreciated.
