we are using 4 CIM motors this year, so there are alot of heat. I was just thinking putting the air tank near the CIM motors , so the CIM motors can warm up the air in side the air tank and increase psi. do you think it will work? 
air pumped to air tank>warm up>relest>air pumped to air tank again>warm up and so on
The CIM’s really take a long time to get hot on the casing. Aslo, raising the PSI won’ty do anything, there’s a blowoff valve that won’t let you go above 120 PSI.
The blowoff valve is on the pump, and the check valve is between the pump and tank, meaning that the pump will not see the higher PSI.
I still don’t know if it would really be beneficial at all, though.
lets see if im thinkin right… if the motors in fact do heat up the air inside, which will raise the pressure to above 120psi… the compressor will (should) cut off, and the valves will release the extra pressure… the now heated air (higher pressure) would allow less ‘fresh’ air in… right?
now that youve heated the air up, there are fewer molecules of air in there… and fewer molecules can fit into the tank before hitting 120psi… isnt that sorta opposite of what your goal was? if anything, id attempt to cool off the tanks as much as possible…and increased tank pressure doesnt mean jack squat on working pressure…
its been a long day so my logic might be a little confusing/wrong- let me know

thx guys
EDIT:
Nope, I was incorrect… the Clippard air tanks are rated to 250 psi.
Here is the spec sheet on them from Clippard (its page 61 in the pdf):
I don’t know what I was thinking about…sorry if I caused any confusion.

Also…if memory serves the Clippard air tanks are self regulating/relieving at/to 125 psi.
I’ll try to find the documentation on this (or recant 
)

Aside from all the other issues noted, I’m doubting the CIMs would be able to heat up the air tanks enough to matter in a 2 min round. The CIMs would have to be too hot to touch and very effectively thermally coupled to the tanks with a heatsink. Then it might make a slight difference. Plus, the air running through cold tubing would quickly drop in temperature and thus lose all you’ve gained until you heat up the tubes and cylinders as well. So I think all you’d really be doing is risking exploding your clippard tanks.
true, but that really doesn’t matter since due to the compressors relief valve will open.
I don’t think I was saying that the 250 psi rating did matter. Sorry if there was any confusion there.
I was just correcting what I had said earlier about the tanks being self regulating to 125, and trying to make sure the correct information /specs are readily available for those interested.
