Remote mount turbo?

One other thing to consider is how long will it take to pressurize that amount of intake plumbing, and what effect will that extremely long intake tract have on off-boost performance (a very valid question, given that everything about the remote mount setup increases the spool time).

The short answer: Shitty low down torque numbers until the turbo starts to spool, and even then, the boost will come on slowly, as it now has a fairly huge space to pressurize; and it has to re-pressurize it every time you let off and allow the BOV to vent the pressure to the atmosphere...

Which raises another question: What kind of monster BOV would you need to vent that volume of pressure -without- allowing it to back-spin the turbine? Probably you would want one very near the turbo outlet, and another post-intercooler.
