acceptable IAT?

etichi · 08-07-2011, 03:18 PM

I have a tune and thats it. Live in Florida where it will hit 100+ degrees on the highways I notice that I am hovering around 130 degrees IAT from my normal way of driving. Is this hot or normal?

130F with those temps is normal for a 335i with just a tune only. Upgrade your FMIC, intake, and meth and you should see IAT's drop considerably.

No kidding? With meth? Lower IAT's?..

Of course...

The other day it was near 100+ and my IAT were 93 degrees with meth and stock FMIC @ 18 PSI

In Alabama, with temps in high 90's and normal driving, I see 12x iat's and that is with a hpf fmic.

90 and humid with Cobb AP and ER FMIC, IAT was 98.

Thanks Jeff!

Is it possible for the FMIC to cool the air to be colder than the ambient temperature outside? Sounds like it would be impossible but thats what they said about sailing upwind.

Maybe + meth.
With meth and my fmic I get pretty close to ambient, and its still 90+ degrees here. Maybe in winter it will

Can't physically cool colder them ambient if ambient temperatures is what is cooling the air charge
