[MR2] A high speed cooling problem

[Jeff C]

Has anything changed with the air deflector or undertrays? That piece plays a role in creating a pressure differential to help air go through the radiator.  I've also read of Mustang cooling being affected by the removal of chin spoilers or fan shrouds. I can't recall if the principle is to increase or decrease turbulence.

 

Another thought...shouldn't fans turn off at high speed? If they run constantly, can they impede airflow?
