Blown N2O
There are more benefits with this line of thinking and that is less N2O usage, and that result per pass doesn't cool the bottle so much, which all leads to allowing the blower and the engine to work together like they are designed yielding consistency. If the blower is not a tight unit that has higher pumping losses which adds heat into the intake mixture, N2O addition will make it seem like the blower has gained all its efficiency again. This the common purpose for using it in turbo cars as well.
