High Intake Air Temp, 50++ Options

[skogs]

All stock ST205 except 2.5" exhaust and standalone ECU. The charge cooler is programmed to start at over 50% throttle or over 45C IAT.

The intake temp starts at 5C and slowly rises to 50-55C. Outside temp is around 15C. How agressive i drive doesnt seem to affect temps by much.

What temps should one except from the stock cooler?

Hi,

your data log isnt that fine when i see your iat it is just a straight line....down there i have uploaded one from me, total build engine, BW EFR6758, TTE water to air tmic, with custom pump and pre-radiator

here the built up if interested

and here a cut out of my datalog, iirc it was ~30°C outside temp. so iam around +10-15°C over outside which is pretty good the theoretically maximuns is called at outisde temp. +10°C



the often called "heat soak" isn't what it is called, you see a high IAT when there is no boost and a drop down on boost but why? the answer is pretty simple, there is no air flowing over the radiator, or in other words nothing to cool down for him, the ic uses no heat shield and i'am using the oem intake box (which get his air from the cool fender area)

in your case i would do the following,

- drive as much water as possible in the system so rais the water ratio (i drive 2/3 water and 1/3 anti freeze)
wate is the best cooling liquid you can find on the world with his high specific heat capacity and heat transfer against glycol

- copy the oem programm of the ecu, my haltech also wasnt able to controll the pump like this so we built a small electronic for around 20€ or something

start, when you hit the gas pedal and a delay of 30sec after the pedal isnt pushed
