yeah heat transfer from the radiator is something i was concerned about. on the track i will be running water spray and possibly a water injection system to try help keep it cool. ive already started making some ducting and various deflectors to try and direct as much air to the cooler as possible. itll be running at least two 10inch ir possibly bigger spal thermo fans that will be left on constanly ie. no thermo switch and also a nismo thermostadt. the afm is also going to be placed either back in the intake or onto the cold side of the intercooler. and all cooler pipes are to be wrapped in thermo tape. it will also be using a vertex front bumper thats been modified to supply more air to the coolers
