What also helps(if you have a FMIC) is foam between the radiator and the intercooler. You put it there so that air is forced to go thru the radiator and to keep it from recirculating back to the front of the radiator at a stand still.



My lower water temp mods:



PFC with stock fans coming on at 86 C low and 89 C high.

Koyo Radiator

Aluminum AST

plastic underbelly pan

foam up front

vented hood

Single Turbo



All of this and I can rail my car from 1st to 3rd gear over and over and over and won't break open the thermostat.
