Well, when I stop at a red light and idle in neutral, I hear this clunking noise 2-3 times while I'm stopped. It feels like it's coming right from under me and I only hear it after coming to a stop. Not sure if it's coming from the exhaust or something. I'm still trying to figure it out so I can word it better lol.

Also, while parked, idling, every now and then i feel my seat vibrate a little, as if the engine had a rough cycle(s) for a moment. I thought this could be normal w/ the fuel injectors and all.

 

Won't the ECM lower boost with cooler, denser air, not increase it?! Coming from an SRT 4, so don't be too hard on me, lol.

 

I thought it should...it didn't make sense to me. but during the winter I boost higher than in summer.

 

I always thought turbos loved cooler air, as cooler air is better? My logic behind that is from what people say which is why I didn't include why.

Gah my car has been too quiet lately.. Doesn't feel right

 

I think that would be right also as the cooler air would make more power with less boost than hot air but who knows lol

 

im guessing its because the cooler air is denser so its creating more pressure. since the hot air isnt as dense it needs to suck in more air to create a smaller amount of boost and with cooler air it sucks in less but creates more boost since the air is a bit heavier or something? im probably sounding like an idiot at this point. lol

 

I've seen SS/SC's do this when the intercooler pump takes a **** ..... I would just double check that you have flow at the filler neck. GMPP exhaust should have been 2.5'' ..... It's too bad cause it does sound great , I had touring on my SC and loved the sound.

 

my ic pump did take a ****. then i replaced it like in mid july with a new one from zzp so i dont think its that. temps stay low as hell while driving around and im in south texas where its hot as **** everyday so if it was out my temps would be over 200 easily lol. stay at around 183

and yes the gmpp does sound amazing...i want to see how much it would cost me to replace the piping to 2.5

 

Your IAT2's stay at 183?! Or are you talking about coolant temp which has nothing to do with the ic pump

 

lol yes was talking about that but i thought it did have something to do with it since when it went out last time my temps would skyrocket to 200+ driving like a grandpa.

my iats stay relatively low also. i dont remember the temps but yeah they dont get into that redzone or whatever much

 

Ic pump might have a slight effect on coolant temps but not a direct effect. The only reason the coolant temps go up when the pump goes out is hotter air is entering the engine because of no intercooling. The coolant temp is not a good indicator of pump function though as several things can cause higher coolant temps. The only thing that points to a bad ic pump is the IAT2's

 

in that case let me look over my last log but im pretty sure the pump is working fine

 

hmm. when i started log my iats were at 102 then when i started driving they dropped to like 95. then when i did a pull they dropped to 77-79. yup doesnt go past like 81 during/after pulls so im guessing my pumps working fine

 

Do you know around what PSI others are getting with a 3.1 on a 2.4L?

 

Is that IAT coming from the intake manifold or from the MAF sensor?

 

Idk lol. Its coming from hpt haha. Its like the gauge on the top right corner

 

What map sensor are you using and did you have to do any rewiring for it? The only way to read IAT2's (air in the intake manifold after the supercharger and laminova cores) is with the 2.5 bar LSJ Tmap sensor. Stock map doesn't read IAT2's but the MAF reads IAT's (air just being sucked in to the intake).

 

Using 2.5

I think it just plugged right in

 

Most likely your reading IAT1 which is your CAI temp and not intake manifold temp.

2.5 bar does just plug right in.

 

how do i read my intake manifold temp?

 

You have to wire the 2.5 bar map to read it. That map doesn't plug right in because it has a 4 pin connector and stock only has a 3. One of the pins on that four pin connector is for IAT2. You have to cut the IAT wire on the MAF connector and connect it to the IAT2 wire on the map connector. Just remembered you are running the ZZP bolt on kit so you probably are running the 2 bar map

 

actually yeah i think i have the 2 bar lol i bought it a while back so i didnt really remember

 

I have the 2.5 bar as my MAP and i read IAT in the intake manifold. Not hard to wire. Just have to find the 2.5 sensor and the connector for it.

Your temp youre reading now will read the intake manifold temp when you switch.
