I only know the EGT for the diesel when it's running efficiently, which is ~600* at cruise (low load).

Even if your grille is completely blocked, if your intake piping is sealed (as much as it can be) against the radiator, it will still pull air through it. There is airspace under there, even if you've blocked the section that normally permits flow. The engine's vacuum will find an air source, with no problems.
