so after cruising around the past wwek my iat 2s have been anywhere from 120-160 usally staying about 160 unless i got on it then they would go to around 190......i put power to my pump and it turn right on no problem took it off and put power to it again it quit working so i hit it with a hammer it kicked on and back off sound like a bad pump?

 

Thats crazy high stop driving that thing around until you get a new pump on.

 

it's a bad pump for sure, you can still drive it around but you should have a light foot, you'll get knock and reduced boost to 90% usually after iats hit 212F I believe? anyways just get a new one.

 

i am on a 2.8 pulley 60's and ottp tune it just seems soo hot they pump decides when it want to work....

 

More than likely bad pump. It is common for our pumps to crap out every 30 - 50 thousand miles or so. So expect to replace it relatively often unless you dont drive much or far.

 

ok well thanks guys....

 

i ended up changing mine like 5k miles ago and i think i drove around ALOT on it being bad, not knowing and I Boosted alot. How much f'd up could my engine be, What would i have to be replacing?

 

If you dont have codes you're probably okay...
If your still makeing power, ect...

If your IAT2s get too high and you get too much into boost, your PCM will retard the timing to help protect your engine. (Knock Retard)

I drove arround on my bad IC Pump for most of the winter, when it was cold haha... So My winter IAT2s were normal for HOT summer driving...

If you want to make sure everyhing is well, pull your plugs inspect them, and run a compression test. if you F'd up your engine, it would let you know most likley.

 

Mine just crapped out and I had no idea, car started to run f'ed up. Opened the hood and saw no coolant through the option b return line, hit the pump and bam it worked and car ran fine. I was so pissed until I figured out what it was. $115 later and UPS dropped it off today.

 

good info guys, im pretty sure mine is on the way out, i started to see 145 yesterday while just cruising around. interceptors should be a must, if i wouldnt have that thing i would have no idea

 

Keep in mind that the temp is getting warmer outside, so even if everything is working normally in your car, your IAT2 temps will rise steadily as we get more and more into the summer.

IAT2 Temp is normaly (while cruise) 20 - 30 hotter then IAT1.
When you stop, it goes up. even if everything is good.

 

Pretty sure mine is out too but I am bench testing my pump this weekend to make sure.

 

i will have to try the hammer and see if that works lol
