Oil Change Comptech SC
Purchased my AP1 and now I need to do an oil change. The car came with a Comptech Supercharger. So the oil drain plug is really a line for the supercharger. I'm scared to touch it because I don't have a open end torque wrench and I don't know if when I tighten it back I would be stripping it. What should I do? Risk it?

What I do is that I use another open-ended wrench to prevent any torque from being applied to the fitting attached to the pan.
The hose fitting to that fitting I just hand-tighten with another open-end wrench...it's not as torque sensitive as what is going into the pan (as that is soft aluminum).
If you want to be precise and use the crowfoot, it does change the overall leverage you need to apply. For example, to hit 10 lb-ft, you may need to apply 9.X lb-ft (indicated) with the crowfoot attached to apply an actual 10 lb-ft, as your fulcrum is longer.

I have a similar drain plug setup (My drain plug port has a line that feeds my prelube pump). Here's my suggestion:
Set your torque wrench to 29 lb-ft and practice on another bolt. Any other bolt. A lug nut will do. See how much force it takes to get 29 lb-ft. Now that you have a feel for the correct force, use the same amount of force with a wrench of the same length as the torque wrench.
I have done it this way for over 12 years. I've never had a problem.
