Almost all FI kits maintain MAF in stock position, so everyone's IAT measurements will not show the real deal. Given your location, the MAF itself may be heat soaking as well.
120F or 50C post blower wouldn't be anything to worry about, we get that ambient near the road around here. I've seen 60C on the pre-turbo MAF during a track session before I decided to pull the trigger on meth. |

yeah i know yours is post blower so your getting "true" IATs, but i still think they are possibly falsely high when under boost just because of close proximity to engine and the MAF "housing" is metal which probably heat-soaks and keeps the MAF from reading the lower boosted air temp correctly. Even if this isn't the case and its reading correctly at 120F in 90F ambient that still isn't bad.

My JRSC setup hit 150F IAT at the track last month in mid 90F summer heat.

On this point I feel like I should be monitoring the post-intercooler temps more closely...any recommendations as to gauges or tapoff ports on the manifold? The only ones I see are the PCV one I've deleted on top of the manifold, and the evap one below. Quote:

@TurboBRZ_UAE One of the MAF wires is for temp, you can NPT tap somewhere post FI put in a threaded temp sensor cut the one maf wire and wire it in. Then the IAT the ecu reads will be accurate post FI temps. Someone had a small write up about this for more details and which wire etc, I think it was @Kodename47

I can't find the info on the wire colours but it just needs 2 to be taken from the MAF and passed to an IAT sensor. I can't find any pics from my install so I'll have to go and have a look in the daylight.

I typically see about 30F over ambient at 10.5 psi.
GReddy T518Z kit, with JDL intercooler upgrade and custom ducting. Oil temps never exceed 225F, regardless of ambient temp; turbo is oil cooled. |
