Air temps before and after the turbo with different setups.

Ok I can't cover it all but I'm going to collect data points once the rain quits and update these for future reference. All testing will be done on the same day so the air as close to possible under each test. If you have any ideas that I could include I will if I can so it will all be done on the same day. This test will be done on two trucks with egr deletes and the same tuning under the same route and speed. The readings will be IAT1 and IAT2

Test to be run W/O AC on
Stock IC /Stock turbo/ Stock air filter
Stock IC /Stock turbo/ Stock air filter w/zoodad
Stock IC /Stock turbo/ Stock air filter with front snorkle removed
Stock IC /Stock turbo/ Stock air filter with front snorkle removed w/zoodad
Stock IC /Stock turbo/ Open under hood element air filter
Stock IC /Stock turbo/ Open under hood element air filter w/zoodad
Banks IC / PowerMax /Stock air filter
Banks IC / PowerMax /Stock air filter with front snorkle removed
Banks IC / PowerMax /Banks CAI
Banks IC / PowerMax /Open under hood element air filter

Test to be run W AC on
Stock IC /Stock turbo/ Stock air filter
Stock IC /Stock turbo/ Stock air filter w/zoodad
Stock IC /Stock turbo/ Stock air filter with front snorkle removed
Stock IC /Stock turbo/ Stock air filter with front snorkle removed w/zoodad
Stock IC /Stock turbo/ Open under hood element air filter
Stock IC /Stock turbo/ Open under hood element air filter w/zoodad
Banks IC / PowerMax /Stock air filter

Don't forget to post up the two truck configurations, every detail as best ya can, as well.

Looking to see the numbers on this, as a baseline of what I should expect.

will do they are very close, both CCLB's single rear wheel 4x4's. one a f350 the other F250. the tunes will both be the same in each written by Eric@IDP Both with open EGR up pipes and EGR delete or disabled so Exhaust temps won't mess with the results. Same fuel from the same source. I'm going to try and keep everything as close as I can. I would rather do one truck but I don't have a zoodad mod nor will I and I couldn't change the intercooler and turbos out in such short time so this is the closest thing I could get.

My data shows 10*+ difference IAT1/IAT2 at idle (OAT dependent). 25+MPH speeds bring that difference to maybe 5*. I have been running a Spearco when getting these temps.

I have modded the intake snorkel as well. IAT1 will be MUCH higher at idle while pulling in the engine heat. ZOODAD helps drop the temps at speed as well.

ok the planatary alignment hasn't happen yet for this to take place but I thought I would add one observation today.

Since it was smoking hot 102*F I thought I would get some data for the heck of it.

my truck intake side of things are a Banks CAI, Banks intercooler setup, PMax, EGR disabled. 65 cruise speed

with AC on max

IAT1 = 102*F
IAT2 = 167*F

w/o AC

IAT1 = 102*F
IAT2 = 146*F

so at least today it looked like a 20*F difference. BTW here is the chart from the run. The red line going down through is the ac on (up) or off (down) then IAT1, IAT2 and boost.

If you can sometime first thing in the morning after the truck has had time to cool down over night. check IAT1 IAT2 ECT and EOT. ECT, EOT and IAT2 should be real close. Some of these trucks and mine was one of them have issues with IAT2 not reading correctly. This issue is outside of a dirty IAT2 sensor. in my case and another I know of IAT2 will read incorrectly for until the truck has warmed up shut off and restarted. This issue lines in the PCM itself. just check sometime and report back if you would because I'm interested in how many of these trucks have this issue. This issues affects timing and fuel trims. Also this issue show up more during the colder months and in the warmer months it can be ok... I assuming you have but have you ever taken IAT2 out and checked to see if it's soot filled (normal issue like the EGR)

ok at the EOD I decided to throw my stock vxcf9 tune back- personal note If I had to run the egr all the time I would only use a vxcf9 due to the enhancements of the EGR function. One being the EGR is shut down when idling for long periods,,,,, funny thing is it's only a couple of minutes and it shuts down. two when towing it and towing heavy it will shut down the egr to save the egr cooler from high heat.. now back to what I saw. BTW for the last two runs I saved some data via AE and if anyone wants to view it via their AE let me know. Also you can download AE and watch recorded logs but nothing else.

IAT1 100*F-102*F
IAT2 avg 240*F-282*F

it didn't really seem to matter if AC was on or not. here is the picture
