My local hardware store (Canadian Tire) has a special on a 8 gallon air compressor rated at 1.1HP, 125max PSI. It states 3.7 scfm @ 40PSI, 2.6 scfm @ 90PSI.

The special ends today, so I need to know what you guys think rather soon...

here's the link:

Is this compressor good enough for a backyard mechanic to run the included impact wrench on stubborn lugnuts and other automotive work?
I have read that you ideally want 5.2cfm at 90PSI to properly run an impact wrench. But the ratings on the site are scfm... so I'm not sure.

I currently have an electric impact wrench, which ain't all that great. If this air compressor combo isn't much better than what I have now, I'll wait for something better to come along...

Thoughts anyone?

Thanks!

I wouldn't want to try to use any type of air tool with that small of a compressor, especially an impact wrench. I would spend an extra couple of hundred bucks and and buy a 20 gallon compressor with enough capacity and cfm to run most tools for a short period. As far as the tools included with the compressor, you get what you pay for..

We've got one about this size. Works great for nail gun and little projects. Probably not bigger tools.
