just a generic query into remote turbos as i really only have the basics down:

a turbo is basicaly a turbine compressor driven by another air source (exaust in the case of the remote turbo?)? wouldnt the air between the turbo & the intake already be there so when the demand is put on the turbine the preasure would rise substantialy fast?

sorry, my only experience with turbines is limited to jet turbines (F404-GE-402 type cool ) so i'm thinking large numbers. as for the rocks & stuff wouldnt it be protected somewhat by the armor underneith?
