Engine Performance Problem

Re: Engine Performance Problem
Between here and Facebook several say 30K. Me, Eric from Ohio for sure. Even in this thread with 34K. I did a search and the first one to pop up was https://www.crossfireforum.org/forum...s-highway.html at 32K.
It is all about putting the problems in perspective. On here and on FB you read about failures, not many have written that their xxxx was still working after x miles.

Additionally I have read where some have used c-clamps or vise grips with something soft in the jaws to clamp the hoses off to keep fluid in while doing the change. I plan on trying that and will report how it goes. EDIT, this method works fine.
Ready to install the new pump

With 70 odd thousand cars made even a thousand failures around 30,000 does not make a benchmark figure. Many failed before that number and many after.

And I made the comment from a diagnostic point of view. When several other SRT6 owners report intermittent low power symptoms and the fix was the pump and the mileage was 30K or so I would not post the recommendation to change the intake air temp sensor. I wouldn't recommend changing the intercooler. I wouldn't recommend changing the SC clutch. I would go with the common reported problem, the pump.
Equate this Dx mindset of going to a medical doctor for a cough. He doesn't test you for throat cancer first, he goes with the most common cause for the cough. IE the most common post I read for int. low power on an SRT6, the pump.
Reliability of 70K + cars is a different thread.

You say IC do you mean the IC pump?
Re: Engine Performance Problem
OK, but the point IS failures. Failure of the pump. We are talking only the SRT6 model so the number made is what? 4000ish?

Re: Engine Performance Problem
Next, if you replaced the temp sensor, I would compare the resistance of the old sensor to the new sensor. Are they the same? If different which one is correct?
Since we know the supercharger is working the first 20 minutes we know the signals to the clutch and the clutch are good. Hook up an OBDII device that can measure live data to monitor the temp of the intercooler air. At what temp. does the supercharger drop out?
These diagnostics might point to the culprit.

Re: Engine Performance Problem
I would imagine that the secondary coolant pump to keep the intercooler coll is there for a good reason. So that you are not putting hot air through the intercooler and then pumping hot air into the cylinders when accelerating hard, causing predetonation. Am I wrong about this? I would guess it is not a good idea to bypass what the heat sensor is telling the ECM.
Re: Engine Performance Problem
I found after changing out the pump I had the same issue with the supercharger cutting out. I found the modification in the forum where the fuse is bypassed to run the pump at all times when the ignition switch is turn on. Must have been some sensor malfunction.
Re: Engine Performance Problem
I ordered the secondary coolant pump and took my car to my mechanic. He said it was not the secondary pump (that was fine according to him) but the regular coolant pump that had a leak Waiting to get my car back.
I will report on whether or not that cured the problem of the car not having 100% of its horsepower available 100% of the time.

Re: Engine Performance Problem
This prior post sounds like the solution to the supercharger shutting down. I have had the radiator flushed and replaced the water pump and the intercooler pump, and I know they didn't do the below procedure.
