Why put the electric turbo after the IC?

Is there a pretty low limit to how much pressure an electric turbo can generate so there's not much point in putting it before the IC? Or better response since it's only pressurizing that short section of pipe rather than the entire volume of the IC?

      - It's not the bulk of the charge and isn't driven by hot exhaust gasses.   -  PKmode  2015-07-30 14:24:54 (190 views)
        
        Still, it's the pressurizing of the air that heats it so if you could have an electric turbo strong  -  bingS4  2015-07-31 06:20:46 (185 views)
        
        Low boost @ flow doesn't really need intercooling.  -  sj6sp  2015-07-31 16:58:49 (172 views)
        
        Sure, pressure creates heat but not in the same way an exhaust driven system will. I mean, does  -  PKmode  2015-07-31 09:35:29 (278 views)
        
        I think it's the act of compressing the air that causes the most temperature  -  bingS4  2015-07-31 15:26:58 (166 views)

    - I'm confused. You say no exhaust gases used to spool the turbo but the diagram clearly shows - PKmode 2015-07-30 11:06:28 (264 views)
      - The electric turbo doesn't look connected to the exhaust manifold to me.  -  bingS4  2015-07-30 11:56:22 (216 views)
        
        right, poorly worded on my part. But the electric turbo doesn't use exhaust gases.   -  S4gasm (LotR)  2015-07-30 12:26:42 (191 views)
        
        Yes, the wording is what threw me. Needed to specify you were talking about the electric turbo.   -  PKmode  2015-07-30 13:38:08 (182 views)
        
        Correct.   -  S4iowa  2015-07-30 11:59:00 (189 views)
