Supercharger expected lifespan?
I have a Weiand 142 that was essentially brand new when I got the car - what do you consider a reasonable expected mileage lifespan? Is there anything you can do to lengthen its life other than make sure the lubricant is changed regularly or take it off the engine?
What do you recommend as an oil change interval - every time you change the engine oil?
Thanks!

Just did a quick search on the Holley website for the manual and it says to check the oil level on the 142 every 1000 miles and to change it every 7500miles. They spec SAE 80/90 gear oil and to keep the level in the middle of the sight glass. They have discontinued the 142, and the rest of the Weiand superchargers, so grab the information while you can.

research the teflon strips that create the pressure in the screw, those are what wears out more than anything else

All hope isn't lost. Screw style air compressors are everywhere in industry and a good compressor shop should be able to help with those seals when the time comes. The case and rotor designs are very similar on many screw compressors on the market. The principles are the same, mechanically stuffing more air into a space than atmospheric pressure will do on its own.

Pretty sure the 142 doesn't use a screw style rotor. It used lobe style rotors. Someone can correct me on that if I am wrong.
Look at it this way, if the 142 eats itself it's an excuse to get a bigger blower!
