My crossfire SRT 6 automatic coupe has only 23k miles and has the folling proble.

I was having intermittent cut off of my supercharger and replaced the intercooler pump with a Bosch pump from NeedsWings. I contacted Needswings and was told to check air intake and it should be around 100f. Mine is about 200f, the same as the coolant. How can air intake be at 100f when coolant is 200f and they are using the same coolant?

I feel a surge in the car and then the supercharge cuts out. It then will come back on without having done anything. Then cuts off again without surge.

Any suggestions.

 

Just for the record, where are you measuring intake air temperature? Before or after the intercooler?
Is it possible that the IC pump is working intermittently due to a bad contact or a bad IA temperature sensor?
Is it working the same or better since the new pump was fitted?

 

I'm using odt2 and taking air intake temperature from it. I don't know where it is taking it

It might run a little stronger than before.

Thanks for replying.

 

Got my letters confused for testing. Should be obd2.

 

​​​​Seems like either your pump is not running or you have an air lock and the coolant is not circulating. You need to bleed air from the circuit. Search for the pump always on mod. Then you can check for flow with the engine off. That's where I would start.

 

There's a possibility you have a faulty IAT sensor. Good thing is their cheap ($7-10), bad part is accessing that little bastard. It's located in the lower Y-pipe, below the throttle body and under the fuel rail. I was having similar issues and that was my fault, along with an air lock in the IC system.

 

Well, I found a mod where by wiring up the fuse for the intercooler, it will run when the ignition is turned on. I wired it up and now everything is working correctly. The temps are at the correct levels and all is not right.

Thanks for everyone help.

 

I'm still having these exact same issues myself. My car has 21,000 original miles and the Supercharger keeps cutting off. The Intake Temperature reads around 170f to 180f and it starts cutting off the Supercharger.

I changed to a Needswings pump, Coolant Isolation kit, new AIT sensor and I wired it for the "Pump Always On" mod. Still have the same issue. What else can it be?

Perhaps air in the system?

 

When you say cut off what do you mean? Is it the hard cut off where it feels like the car has no power when you give it gas which is the blower clutch disengaging the pulley completely due it being too hot, or the random kill when it feels like it goes out for a second and comes back on?

 

Thanks for looking philosophico.

Meaning, the Supercharger kept disengaging. I figured out my problem this weekend. When I installed the new IC Pump is when I also wired the system for the "Pump Always On" mod. I started going back through all of that and found that the terminal connector on the fuse box end had worked itself loose. After fixing the connector I took it for a ride and my intake temperatures read 85 degrees and stayed there instead of climbing to 185 degrees, which tells me the pump was not running at all. Now she rips and keeps on ripping like she's supposed too.

 

 

Yeah, I had been racking my brain reading through all of these threads. Oh well, I now have a really good education on how the cooling system(s) work on these cars.
