sfpar Posted November 1, 2007 Share Posted November 1, 2007 I'm curious to know what some of you intercooled guys are showing on your air temp. I am running about 190 and don't know if that is good or bad. Thanks. Quote Link to comment Share on other sites More sharing options...
big-phil Posted November 1, 2007 Share Posted November 1, 2007 Man I just got back from a little tunning run. But I didn't notice what the air temp was. I have to take my daughters friend home in a bit. I'll hook the lap top back up and take a look. Quote Link to comment Share on other sites More sharing options...

OAT was around 60 degrees. BTW, your car is coming around. Looks great. Finally got mine running pretty good @ 12lbs of boost. I really needed that MSD w/ boost retard. Looks like the widow will be placed in storage for a couple of years. I will be relocating to Japan. Figures, now I don't need any more parts.

big-phil Posted November 3, 2007 Share Posted November 3, 2007 this is weird, we lost our power on Halloween plus I took my truck to get the friend home. My daughter wanted to go also and trick or treat. I'll try to get a reading tomorrow. Quote Link to comment Share on other sites More sharing options...
ktm Posted November 4, 2007 Share Posted November 4, 2007 My air temps are around 85 to 95 degrees. Not once I have seen over 100 yet. Quote Link to comment Share on other sites More sharing options...
sfpar Posted November 4, 2007 Author Share Posted November 4, 2007 My air temps are around 85 to 95 degrees. Not once I have seen over 100 yet. Thanks Bo. I'm going to monitor mine and make sure it's about the same. BTW, What are you guys showing as your normal op temp after warmup? My car seems the run at 206 degrees and the gage needle is in the middle. scott Quote Link to comment Share on other sites More sharing options...
zguy36 Posted November 4, 2007 Share Posted November 4, 2007 With a 1/4 mile run, I usually do not see temps that are any more than 30 degrees over ambient temperature. This is with about 19psi of boost. Quote Link to comment Share on other sites More sharing options...
big-phil Posted November 4, 2007 Share Posted November 4, 2007 today with the outside air temp at 75deg F, my coolant temp was around the 185-191deg F mark, the intake air temp never got over 51deg F. When I feel the intake of the intercooler its hot, and the outlet feels almost cold. Like a can of soda thats been out of the fridge for 15-20 min or so?? Fricking intercooler is AWESOME! I got into boost a few time, but did not kick the car's a$$ or anything. Mostly normal driving. Hope that helps. Quote Link to comment Share on other sites More sharing options...
datman Posted November 4, 2007 Share Posted November 4, 2007 Mine runs about 10 deg F above ambient on a 60 deg day I have MAT of 72 under 10psi of boost Quote Link to comment Share on other sites More sharing options...
ktm Posted November 4, 2007 Share Posted November 4, 2007 My normal operating temperature is 180 to 190. The needle is slightly to the left of center. Quote Link to comment Share on other sites More sharing options...
jgkurz Posted November 4, 2007 Share Posted November 4, 2007 The max I've seen on the data log from the MAT (Manifold Air Temp) sensor is 46C/114.8F. That was during "heat soaked" dyno pull with ambient temps at 80F and 23psi peak boost. Laste weekend while on the freeway I logged 30C/86F at 21psi peak boost. Outside temp was around 55F. Look at post #38 on the below thread for another example. http://forums.hybridz.org/showthread.php?t=121857&page=2 Quote Link to comment Share on other sites More sharing options...

Big Phil, I'm not doubting that is what the datalogger is reading, but if ambient is 75 degrees F and in IAT is 51 F then the intercooler is running at more than 100% efficiency. I'm wondering if you're runnning an IC sprayer? Does your methanol injection help that much? Damn!! Quote Link to comment Share on other sites More sharing options...

I'm wondering if you're runnning an IC sprayer? Does your methanol injection help that much? Damn!! I was kinda wondering the same thing all day today after I posted that? How can my intake temp be below the temp outside?? I might have a bad intake airtemp sensor? My meth does not spary untill 14-15 psi. But when the car idles, the output of the intercooler is "cold" Can anyone confirm if its possible for this to happen?:hs: Quote Link to comment Share on other sites More sharing options...
hughdogz Posted November 4, 2007 Share Posted November 4, 2007 Can anyone confirm if its possible for this to happen?:hs: Big Phil, someone just called me from Roswell, New Mexico and they asked if I knew how to get a hold of you. They said they want their Intercooler back! Hmm...I would think that either your IAT sensor is bad, the transfer function is bad (the map of voltage vs. temp) or there is a big enough pressure drop through the IC that the air temp is dropping (which doesn't seem likely). I'm just throwing this out...I'm way less experienced than you guys are. Quote Link to comment Share on other sites More sharing options...
big-phil Posted November 5, 2007 Share Posted November 5, 2007 I had one sensor go bad and this is my second one? They are both used so I don't know? Quote Link to comment Share on other sites More sharing options...
datman Posted November 5, 2007 Share Posted November 5, 2007 I think the only IC that is 100% efficient is a water cooled type used on boats, maybe the Sensor needs calibrating. Quote Link to comment Share on other sites More sharing options...
BayAreaZT Posted November 5, 2007 Share Posted November 5, 2007 I have no heat shield, hood vent or turbo/DP wrap so I have a pretty bad heat soak problem on my car. On hot days the manifold air temps gets up to 120F at stoplights. During normal freeway driving it's usually about 10 to 15 deg above ambient. I just got some wrap for the DP to try and control the heat soak and I'm eventually gonna put a manifold heat shield and maybe a turbo blanket. My temp sensor is mounted on the intake manifold BTW.

mario_82_ZXT Posted November 5, 2007 Share Posted November 5, 2007 I've seen over 220 deg IAT with no IC installed... With my NPR on my ZXT, I would see maybe 20 deg above ambient after romping on it. Most of the time it was at 10-15deg above ambient. My friend modified my NPR intercooler to fit my Z better. I hope to be installing it soon. Mario Quote Link to comment Share on other sites More sharing options...
