Default Intake Cooling with Compressed Air? - 07-11-2018, 11:32 AM

Not supercharging, just cooling. I was overthinking car modding, specifically the idea of using a little nitrous pre-turbo to cool the intake air, increasing turbo efficiency and reducing intake manifold air temp. Plus it's nitrous, so more power. But I wouldn't want to use much, and of course it's one more thing to go wrong and blow the engine.

If the intake cooling effect of N2O is from reducing the pressure from compressed to uncompressed, could you do the same thing with compressed air? You could go crazy with the flow, like a "500 shot" equivalent, and I think it's pretty cheap to fill a cylinder.

They say if you can think of it it's been done, but I don't know.
