For such air tool, an eight-gallon tank would not be enough, would it?
Tank size only matters if you require continuous (?) CFM @ a certain psi. For a DIY a smaller tank can potentially work. Have to check the Airtools you intend to purchase. I would say a minimum of 2HP depending on the brand.

"Powerful 2.5 HP 4-pole motor produces 4.2 CFM at 90 psi for increased productivity"

I recently purchased a cordless 20V Porter Cable Impact gun. My primary use was going to be for rotating tires, the advertised max torque was way higher than it can actually deliver. I don't trust it to deliver the torque required for tightening wheels. How many FT/LBS. have you lost by the time you get to the 20th lug stud. I've basically shelved it and prefer using my cheapo 1/2 Lowes (kobalt) air gun and 20 gal. compressor, I can get 120 psi out it.

I wrench by hand, too, where possible. However this tool is still handy when you need to undo nut on crankshaft or Haldex. That says, I barely use it :)
I also barely use it. But when switching to studded tires, I would have to switch at least eight tires. Too much to unlock the lug nuts by hand wrench before using the impact wrench for speed. If I could use the power too from start to finish, that will be a plus for me.

The 20 Gallon with 120 PSI delivery is the most ideal for anyone who likes to work on cars. Unfortunately, most DIY'er won't shell out for such a large unit besides space constraints in the garage. When you exceed a certain HP you'll also have use 220V 1PH meaning a new Breaker and Wiring.

Don't know about you but age becomes a factor.

I don’t trust the impacts to give me the torque I like on lug nuts. I lube mine so I torque to about 75 Nm

I crack them with a 24 inch breaker ( easy) then use a cordless 125 ft lb Bosch 1/2 to zip off and zip on.

I then do a final nip with the 24 inch on all nuts to my final torque. Hard to describe but I’ve learned the correct tightness where they never loosen, but all of the ladies can loosen them with the car lug nut wrench. The smallest , Abby , uses her foot, while my soccer athlete can twist them off with her fingers. ( badly behaved boyfriends get their limbs pulled off before they get wood chipped)

Oka - there is a thread from the P80 Forum discussing these from two years back here

viewtopic.php?f=1&t=84000&hilit=impact+Bosch&start=10

The 125 ftlb Bosch my kids bought me is a champ for the zipping on and off. If you really want to not use the cheater, I think you will need a pretty expensive 3/4 inch, 12.9 AMP cordless with a very high torque rating

I wonder why my heavy duty electric impact wrench won't loosen the lug nut and these cordless can.
Thought it would have been the opposite.

Because in US we have 110v. With typical 7 Amps it is only 770 Watts of peak power. Modern batteries in cordless tools allow peaks well north of 1000 Watts.

I have an air impact gun, and recently added harbor freights new high flow disconnects. For $5 it's a pretty significant improvement. I never had issue before but after a lot fewer hammer hits before the bolt wizs off.

Your Trades Pro Impact Wrench is only 240 ft. lbs of torque.

For breaking loose you need a big boy like this, 1050 ft. lbs of bolt breakaway torque. $100.00 at Harbor Freight.
