It could be cooling the charge so much that the pressure drop is relately to temperature drop. You must be talking about sub-zero inlet air. Theremust be a mathematian here to calculate the density increase due to the pressure drop of 0.2bar at 5-6kg/min of air.
The air inside inlet pipe must be experience something like a snow storm in the Arctics.
The cooling effect must be so effective as the actual latent heat conversion is taken place during the entire journey inside the inlet tract, unlike the propane and N20 injection where the eveporation is taken place at the point of injection.
Do you have a temperature probe to record the actural temperature drop?
