have run a TMIC (PWR) for years with around 1.3bar, no worries at all, havent even got a water spray.

Where your TMIC will fall down is summer city driving, if you are often travelling below say 50km/h and stopping at lights alot then dont expect much go from the lights, your TMIC will get hot to touch in about 30sec to 1min of sitting and idling. If it's a tube and fin then it will cool back down reasonably quick, (about 2min of speeds above 60, bar and plate a bit longer), on the fwy you will have minimal issues.

Front mounts have none of this and can cool more air faster, drawback is a bit more lag apparently, however, when you want to drive fast, you keep the revs up anyway..
