The main thing I've noted since purchasing my SRT6 (which came with exceptional Chrysler Dealer mtc records and a clean CarFax), is that SOMETIMES - NOT EVERY TIME when I try to "punch" it - usually to overcome a slower vehicle on the freeway, or to merge in time - there isn't a really hearty surge forward. I'd think this bad **** would get up and MOVE when I gave it a good amount of gas every single time. To be honest, it actually surges forward best when I give it just a tiny bit of gas while I'm already at a higher speed.

Still... that sized engine should ROAR forward every single time I give it a good bit of gas at 30MPH, no? It's part of the reason I bought the thing. Instead, sometimes it simply begins to pick up speed as if I'm bombing around in some old K car... that OR an almost comical-feeling overdrive kicks in as I slowly pick up speed (this especially going up a not-so-steep hill by my home). This engine is capable of far more than this, I am sure. I mean, my 6-cylinder Saturn Aura with 247hp has more consistent get up and go than this SRT6. When it's on, it's a beast, but when it's not, it's downright embarrassing. **I merged ahead of someone in an old minivan once after first getting it, with plenty of room, and almost got rear-ended as it caught up to me before I could get it up to speed!**

Any ideas? Having felt it was a pressure pump issue, I found this forum and noticed the ICP was a common theme. As my SRT6 has 23K on it, I feel this is the issue. Sounds similar to what others have noticed.

I've got the OEM replacement from Needswings, and am about to install it (finally!!). I'm REALLY hoping this is the issue. That said, has anyone experienced anything remotely like this in their SRT6? If so, what did it end up being.

 

The poor acceleration symptoms you describe point to a bad intercooler pump. Your installation of a replacement pump should cure your problem and put a smile back on your face when you hit the accelerator pedal!

 

Grab your ***. You are going to love that car even better after install. Be sure to get any air out of the cooling system...

 

If, I say if the intercooler under the supercharger is leaking it won't noticeably affect the power. A faulty intercooler pump is most likely your problem as already specified. Check the fuse first.

Yes, the Intercooler Pump sounds like your problem. I was having the same issues you had described a few months back and I went ahead and purchased an exact OEM replacement Pump and man oh man did I get some intense acceleration from all different angles that were lacking a lot of the time. I gotta tell you it was like NIGHT AND DAY of a change! replace the pump and love your SRT6 that much more

 

He stated intermittent Les. So, he has the power sometimes....wait until he gets his pump replaced. It has probably been that way for sometime...

 

End of Thread

A very appreciative THANK YOU to those of you who've responded to my two posts. It was indeed, as everyone had assumed, the intercooler pump. And Oh Dear Lord what a difference. Mine must have been godawful, because I'm telling you: this is a totally different car now. Wow.

Also, thanks to this forum I saved $2200 quoted install! For 3 hours work. Honestly, the worst part of the project was getting those $*%# spring clamps off. I replaced them with worm clamps, as suggested. And I used the OEM pump: I'm sure another brand may have gotten more juice out of the fuel, but I am EXTREMELY happy with the OEM pump.

Once again, thank you, thank you, thank you fellow SRT6 owners.

 

Geez man. Don't got back to the shop that quoted you $2,200. Glad you got it sorted it out. For first timers running into the intercooler pump issue they always suspect the worse until they find this forum and figure out it is a (relatively) cheap and easy fix.

 

I had exactly the same before/after experience with my recently purchased SRT6. For $110 for the part, we have a beautiful Art Deco bat out of hades. I have the suspicion that the previous owner of my (and your) car got quoted similar prices ($2,200) to repair the problem and just decided to sell the car rather than face that cost on a 2005 model year car.

 

Hi guys, I think I have the same problem. The sc seems to drop in and out. I have noticed it drops out when the temp gets at about halfway on the gauge and when it drops a bit the charger will work.. Put my hand on the ic pump to find that the water pipes are cold so am guessing its buggered? Your thoughts? Also from what I can pick up here, it is still okay to drive it for now without doing any damage? Your feed back would be much appreciated. 😃

 

You need to replace the intercooler pump located in the right front behind the plastic inner fender. Total cost should be less than $200.00 if you install it yourself (new pump and fresh antifreeze . . . be sure to get the correct antifreeze). Do a search on this form for "intercooler pump" and you'll find LOTS of information on this issue and fix. Replacing the OEM Bosch pump (they ALL go bad) will solve your problem.

When I replaced my failed OEM Bosch pump, I went with the Johnson CM30 pump. Here is a "how to" link with photos.

Since that time Bosch has come out with a new upgraded pump which seems to be the current "go to" pump as it's a more simple "plug and play" installation (no need to do any rewiring or modifying of the mounting bracket). The part number for the new Bosch pump is 0392022010. Here is a link to the upgraded Bosch pumps that are currently available on E-Bay . . .

Yes, you can drive the car as it is without fear of damaging the engine but you'll want to replace the pump at your earliest opportunity to enjoy your SRT6 power again.

Let us know when you have everything working again . . . HAPPY NEW YEAR!

 

When my SRT6 was first dyno tested it was at 249 whp, and after getting 65mm pulley and ecu tune showed 305 whp. Jerry at eurocharged was of the opinion that both results were quite low, and that typical stock was 285 whp and post pulley tune results were at and above 345 whp. So, we agreed that the very low results might be due to a dead IC pump. The pump was replaced with a Bosch 010 pump and the car woke up like crazy. I opened up the original pump and it was full of metal shavings. Later this month I will get a new dyno run on the very same dyno to see if/how much whp was restored by replacing the intercooler pump. After very extensive searching, I have not found a before/after dyno run that shows the actual WHP loss a dead IC pump causes...or at least a sense of the difference on a tuned/pullied srt6. After getting that baseline run done, we'll put on a CAI and see where we end up. I hope that this data will help future and current owners. I feel fairly certain that many SRT6's are being sold because of IC pump failure, a $110 part!!

 

More luck to us!

Looking forward to the results of your run.....

Thanks Red Dog. Will be onto it as soon as. I know where you are coming from when that charger works it's a lot of fun. 👍

 

Hi All again. Right i have found now that the electric side of the pump motor is going. Pipes still cold. What gives out in these pumps, The electric motor or do the impellors collapse in the pump side?

 

I think the magnet in the DC motor cracks and breaks into pieces. The motor then operates only intermittently and not at proper speed / efficiency. Replace the pump!
