I've been reading that normal iat2 numbers are 20degree higher than temp outside? Is this accurate

Tjolley

Yes and no.

I would say my iat2 is 20 above iat. Ive noticed from time to time that the iat1 will be a few degrees higher than wat the outside temp is.
Now this is a different story if ur doin a pull.

Well I don't really get on the balt too often, when I do yes it jumps but falls quickly , but I was just curious for cruising temps not stuck in traffic or doin pulls if that general area was correct

Comparing IAT2's is like trying to compare boost.

Too many variables can alter results.

Generally though while cruising anywhere between 20-30 over IAT1 is fine. During a pull you want to see sub 140's.

Fast recovery is key.

Tjolley

Ya im on a 2.5 on my m62 i see about 140-145 at the end of a race.

Tjolley

Unless im runnin nos. It somtimes goes below the iat1

riceburner

iTrader: (66)

while idling my iat2 goes up to 40-50 degrees over iat1 (which is usually right about at ambient)

cruising i see 15-30 over

and during a pull i usually dont look till after and its around 130-140

i got all deh cooling mods though. but a leak in my system. small. but its there

my setup: 2.8", 60#s, opt b, dual pass, ottp stg1 h/e, 5 gph meth injection, and phelonic manifold spacer

microgab

^Same as riceburner. And I have a #3 ZZP heat exhanger, dual pass, phenolic spacer

Its been about mid 80s here and I'll stay at about 100-110 cruising if I do a pull prob 130-140 I have a zzp heat exchanger no other cooling mods tho

Tjolley

Wat size sc pulley?

Staged07SS

iTrader: (25)

Those are perfectly normal IAT2's.

The addition of a dual pass aids in recovery. Not so much IAT2 temp level.

wat

riceburner

iTrader: (66)

When im seeing 40-50 above iat1 at idle i was really starting to get concerned guys, i thought it was supposed to be like 15-20 at idle

07ssBOOST

iTrader: (1)

2.9 pulley and when I WOT it may spike to 140 but goes back down in no time

Staged07SS

iTrader: (25)

Again. Perfectly fine.

riceburner

iTrader: (66)

so if i'm seeing 540+ during a 0-170 pull i got issues

Verbatim

iTrader: (1)

I have flowthru opt B, phenolic, dual pass, ottp FMIC, 14gph 50/50

I see 18-23deg above ambient, doesnt mater idle or cruising
After a pull I see 25-35deg above ambient temps

I did 3 back to back pulls one day and saw temps 10deg above ambient...i giggled

will be stepping to 2.6" pulley and 20gph 50/50 when I get my head back in the next couple days.

I ended up buying a stealth H/E on blackfriday. a local buddy coverted his LSJ with a LNF stock turbo setup. So I scored a awesome deal and swapped my dualpass for his zzp single pass intake manifold

Ill see 20-30 degrees IAT1 IAT2 difference at idle
16-18 degrees difference while cruising on the highway
16-25 if im in the city hitting traffic lights
and I haven't seen over 132F on the IAT2 on WOT runs
ZZP singlepass / ZZP stealth heatexchanger / ZZP Phenolic spacer
but I haven't experienced any real hot summer days yet with this new setup.

I used to run zzp dual pass / zzp S3/ ZZP option B / ZZP phenolic spacer and my IAT2s ranged from 20-30 while cruising
20-45 in the city with traffic n such
ive seen 145 at the end of WOT runs

IAT2s are a bit lower with my new setup. but the recovery time of my IAT2 after WOT was the most noticeable change.

Ok so on the way home...

Ambient temp: 80
Idling: 30-40 dregree difference
Cruising any speed: never under 25 over iat1. Actual iat2 stayed 105 pretty much
1st-3rd pull: hit about 144, was under 110 about a minute after while still cruising

I just think my numbers could be much better

Just messing with HP tuner my IAT's hit 113 here in vegas but its just getting hotter and hotter by the day here. suppose to hit 109 this sat 113 is normal correct? just wonder what else should i do to prepare for this summer? I have ottp h\e, option b, zzp P spacer not installed yet and working on getting dual pass.

When it's hot as ***** out, just stay out of the throttle. Simple solution.

Tjolley

2 words killer chiller!!!

It usually get to about 110 in modesto.

riceburner

iTrader: (66)

i'd love a killer chiller.

my car (like any car i guess for that matter) is a total DOG when its hot out. But im not about to go three months without giving it some pedal.

Staged07SS

I didnt mean you can't give it throttle, but on super hot days it's best not to beat on the car.

I'm happy to live in Northeastern PA. Temps only get hot for a short period of time. Most of the time it's nice and mild.
