I'm assuming no oil cooler and NA?

[sickmint79]

yes that is correct. no cooler no sc. ordered parts to make the forester oem cooler, planning to go twin screw eventualy, methinks.

@CSG Mike @CSG David I am curious to see data of your iats vs ambient while on track and while cruising.

Coolant temps seem real low unless you are just heading out of the pits on a cold engine. I'm seeing similar oil temps on my stock setup as well for Oil but hitting 196-200 on coolant temps with the Koyo Racing Rad.

lap 5, over 15 min in. toyo_ect says 180 to 185. i'm confused because toyo_iat also says 68 to 73 and it was 85 out - that sounds quite off no?

Yes definitely sounds off. On my car which is essentially stock, IATs are at best 7-10 deg OVER ambient. If your engine was running at 180-185 I would think there is a T-stat issue perhaps.

@mkivsoopra
Aim solo DL has a bug for coolant temps. Coolant reads 18 deg lower on aim solo

That solves the coolant temps. What about the IATs?

I believe someone mentioned that Coolant, IAT, and ambient are all offset by 18F: http://www.ft86club.com/forums/showp...7&postcount=30

I confirmed that Coolant is off, and AiM acknowledged that it's a bug that they're fixing. I didn't ask about the other temperatures, but hopefully they wil be addressed as well. Oil temp appears to be correct.

IATs are usually around 30-35F over ambient, regardless of ambient temperature, when running hard sessions on track.

During cruising, IAT is ambient. For single WOT pulls, you can watch IAT climb with boost, and drop back down as soon as you go partial or lift, but nothing crazy.

IAT can't be off, because it has AAT, and IAT usually matches AAT when under light load (cruising), which is what it should be.

My cruising IAT is always 10 deg warmer than ambient. I am guessing either because:

1. ptuning air filter is in engine bay
2. oil cooler is in front of IC
