How cold is too cold?
My fellow geeks and I were discussing this at work today. But how cold is too cold for the intake charge? Assuming you could keep most of the condensation out of the air, is it possible for the air to be too cold?
I know by using the old butt dyno my N/A truck runs a ton better during the winters here than in the summer. We were just wondering how much power could be gained with cold *** air.
The subject of fuel cooling came up too.
So what do you think?

It gets pretty cold up here.

But this is not always so, take a carburated vehicle that is jetted really close to perfect at sea level (temperature 80-90), then drive it to the mountain (temp 60-70, elevation +6,000 feet). The car or truck will run very rich when you arrive at the moutains even though the temperature is colder, so jetting is required to bring the performance back up, EFI are capable of motoring fuel/air mixture more precise. This is because air is less dense at higher elevation than at lower elevation.
So to ask your question how cold is too cold for the intake charge, that depends on what the intake charge is. (you might be thinking wtf, this guy is nuts or been smoking something) I do have to agree with MikeGuyver assuming you are at the same elevation.
Here is thought on how to get your air temperature down, really down, run liquid nitrogen through a heat exchanger, just like an air/water intercooler.

Oh I'm not worried about getting the temp down, I have my own ideas about that. If everything works out I'll share them with ya'll.
I was assuming the same elevation, sorry I didn't clarify that. Plus I don't think nitrous is a good comparrison. When it exits the nozzle it undergoes a phase change, and it DOES cool off the intake charge considrably. Hence freezing of the MAF on dry shots.

There's CO2 system that puts a venturi with a CO2 chilled element into the intake tract to lower the intake air charge.The same company uses another element around the fuel line to chill fuel feeding the motor.

Yup seen that too setup too. This "idea".....more of a dream at this stage, is continuous. With the other designs out there, the CO2 and N2 are compressed. Once you release them, that's it. Unless you can recover it and compress it fast enough to start the cycle over, its a one shot deal. Kinda like a shot of nitrous.
So no answers to how cold is too cold?
And no I'm not using the truck's AC system. Who wants to have to run their AC all the time. And besides it shuts off under WOT.
