sitting at an idle my mat is about 107*. then when i actaully start moving its gets about to 100 or a little less. i have a atr intercooler, aux exchanger, jabsco pump, and all rubber heater hose.

oh ya and also. when someone says there mat are almost "ambient" what does that mean. sorry for the newbie question.:)

Basically it's the temp of the air your breathing, so the closer you can get your MAT's to the ambient air the better off you are.

EGR is a contributor to higher MAT during a cruise condition. This is more a factor on street driven trucks than at the strip. EGR is off at idle and at WOT. Idle MAT can vary alot based on how long the truck has been driven, how hard, etc. There is no airflow when the truck is standing still to cool anything.

Best to check MAT at WOT where there is high airflow through the intercooler and the air consumption by the engine is maximum.

Finally, the obvious was stated before, it will change with ambient temperture.

now i know this isnt right. on the freeway today my mat's were at 127* and even when i would go to wot they would only drop 5 degres or so. and i used to be able to open my hood and my intercooler and intake would be cool to the touch. now the intercooler is barely cool and the intake is hella hot. and also now when i go up hills or stuff like that my water temp goes up to like 190* and i have a 160 thermostat. now im gettin frustrated. someone plz help me here! this really sucks to because today is my 20th b-day :new-bday: :drinking: :drinking:

Well my ic pump is beat and my mat temps are between 130 - 147 but they dont' rise past 147 at all. So I guess you could say your #s are ok? :)

I have a 180 stat and my engine temp has never went over 178 ...

Just my two cents

ya i have never been able to get my temps above 165 and now they do whenever i jump on the throttle. and i think my mat's should be lower with all my damn intercooler mods i have done. atr inercooler, aux heat exchanger, jabsco pump, rubber heater hose, and aquamist injection. and i know this is a big reason why i have so much knock retard. so im looking for any help i can get....................... :banghead:

do you guys think that if my ic pump wasnt workin right that it could cause this problem?
Man oh man that is a redundant question :D Of course your MAT's will be high if the pump is toast.Check the fuse behind the alternator.

i have the jabsco pump that comes with the atr aux heat exchanger. i think it might wire in differently than the stock ic pump. but ill give it a check.

Make sure the IC is full. You should see some coolant movement with the pump running. Make sure there are no kinks in the heater hoses.

EGR conducts heat to the manifold even when not enabled. Blockoff plates and plugging the intake manifold help.

are sure you are not seeing false knock??? Have you made sure that you do not see knock when you rev the engine in neutral?

As for your IC, I have a strange issue with mine where it will not self-purge air pockets.. I actually have to use an external pump to pump coolant through the system and push the air pockets out..

To do this I cut my rubber coolant return hose (heading down to IC) near the cruise control unit.. Then I put a female garden hose connector on the lower half of the hose and a male connector on the upper half..

I use a submersible pump in a 5 gallon bucked of water/antifreeze to push coolant through the system. I force it down through the lower IC, through the pump and back up to the upper IC.. I use a short piece of hose to route the exiting coolant back into the 5 gal bucket.. after the bubbles stop I crimp the hose(using a clamp) as close as possible to each garden hose connector, screw the hoses back together and remove clamps..

My IC system works VERY well.. I have removed my EGR system and I have an ultimate chip so I don't have that egr warming everything up problem..

The IC stays cold to the touch(even after a run) and the Intake just gets warm.. I haven't hooked up diacom in over and I don't remember what my temps were... I think good numbers are 10-15 degrees over ambient..

My IC system does not develop air pockets unless I remove the cap.. If I remove the cap a good amount of coolant spills out and I develop air pockets again..

I do not understand the air pocket problem as the IC is the highest point in the system.. It should work OK filling it from there..????

BTW, I smoked a GT last weekend and I plan to post the video as soon as I figure out how to convert uncompressed AVI files to DivX..

Matt - Congrats on lighting up the Rustang !

I'll be putting in the all rubber hose IC Mod also. What pump do U have ? I've heard that a strong enuf pump or 2 pumps will get rid of the air pockets. Hopefully my Shurflow will do it.

Matt,

Rick Nolan just discussed his dual core, dual pump IC installation in the last few weeks. He said that he could only get the air out w 2 pumps. I will forward all this info if U can give me your EM address.
