You can see where I mounted the sendor, its a pretty ugly little unit, but I'm more for function than form so it will stay. The remote filter idea is a good one, if I ever go that route it would be on my list of things to do once the car is complete and al the bugs are worked out.
I think you might be right with the clutch, I never even thought about freezing since I've never seen it happen before. I probably won't take it on any more test runs until spring now considering there is a foot of snow. I would go out and hold the clutch in and get the engine torque to break the clutch loose but there isn't anywhere to get traction anymore.
I'm feeling a similar situation here in Canada with the dollar, not as in Aus but still enough to slow things down.
