Extra air tank?

[zags]

Okay, so my 60 gal compressor blew up today after 15 years of hard use. A rod let go cracked the block. I always wanted a bigger one, so I stepped up to an 80 gallon that pushes 14 CFM at 175 PSI. So I was thinking of removing the compressor from the 60 gallon tank, then plumbing the tank inline with my new 80 gallon for 140 gallons total. I am hoping this will let me run higher volume air tools longer without the compressor having to kick in. Does that make sense? Are there any drawbacks to this setup? Space is sort of at a premium, so if there isn't much of an advantage, I probably wont bother with it.

As you say, the upside is that you'll be able to run longer before the compressor kicks back in. Downside is that when it does kick in it will have to run 1.75 times longer (since the 60 gallon tank is 3/4 the size of the 80 gallon tank) before it can shut off.

Won't the pressure be less if you up your capacity by 60 gallons? As I understand it, 175 psi will come out slower from 140 gallons than the same 175 psi in, say, 10 gallons?
So tools like impact wrenches would be adversely affected?

Ummm... No...

As I mentioned before, you're going to take longer to fill that 140 gallons up. But pressure is pressure - it is going to come out of the tanks at the same rate provided that the pipe is the same size.

I can't imagine needing an extra 60 gallons of storage. We ran an 8 bay shop with 4 lifts and pneumatic tire changers with an 80 gallon compressor with no trouble.

Now that I have used it over the weekend, I am finding that this compressor is more than adequate as-is.
