Default Super Charger Unpredictable

Hello Guys,

Issue 1:

I'm new to this forum and new to the SRT-6. I recently bought a 2005 SRT-6 with 13,000 miles on the clock. My issue is that I find it difficult to predict when the SuperCharger is going to take effect. I have never driven with a Super Charger before and I know there are terminology issues when people say, "it's always on", I know that, but I believe the engine is choosing whether to use the additional power based on my driving style.

Or am I completely wrong and in fact the additional power that the Super Charger brings should be there all the time, constantly available. Please don't misread, when it is 'available' it is very quick.

I've been told that there is an electric clutch which could be getting disengaged, but to contradict that I still here the whistling of the SuperCharger, however the sound of the engine is different, it's much more of a high pitch noise rather than a grunting, deep sound. The power is gone.

Issue 2:

It's four years old and due for a B Service, the garage is telling me that I need a “Four Year B Service” which is twice the cost of a normal B Service. It has only down 15,000 miles and I'm not sure it would need a Four Year B Service. What do you think?
Its going in for service on the 16th of April, a couple of days time.

Andy

service b is just basically oil change, air filter change, cabin filters, wiper blades..thats those type of things.

i dont understand why they would need to charge you double, sounds like there trying to ripe you off. Most of the service b stuff you can do yourself.

if you dont have a pump, i say just pay for the oil change and do the filters yourself.

Don't worry about having a pump like a Topsider. You can change the oil like any other car (just as the service manual recommends) by jacking it up and draining the oil from the oil pan by removing one bolt. It is easy! You'll just have to remove the plastic under-tray which is also easy.There are tons of DIY articles for that and the service manual posted in the SRT forum. Do it your self, it is easier than baking a pie and you'll learn about your car and will have the satisfaction of knowing you did it right! As for the supercharger, do a search; there is plenty of info for you.

Hi Guys,

Thanks for your reply. I’m not too car savvy at the moment and as silly as this might sound I would like the main dealer to service it because I would eventually like to trade it back in at the main dealer and reap the reward of that history.

With regards to the SuperCharger, I’m afraid I have done a lot of searching and asking people about this issue and I plan on getting the ECO checked for errors, as when it physically works, it works. So I can’t see that there is a major issue. I think it might be just software based. I would like to know if anybody else has experienced the same issue though?

Its probably your intercooler pump going bad. There are alot of threads on this subject. See if your symptoms sound familiar. Its a relativiley easy fix. I would suggest just buying a Johnsons cm30 pump and not just switch it out with another factory pump doomed to fail again.

Probably the pump. Easy fix, like less than $200 for a better one and easy to do yourself. Be sure they put 0w40 synthetic oil in. Dont pay for some overpriced B service.

ford lightning intercooler pump from ebay: $79
replace it yourself in about 30 minutes: $0
The satisfaction of doing it yourself instead of spending 2 hours or more arguing with the dealership that they do not have to replace your supercharger for $7000 or more, priceless.

Many times dealers pad service with a list of worthless crap jobs that you don't need but for which they charge a lot.

That said, there are a few service items on a Crossfire that need to be done outside the scope of the A/B service schedule.

In auto it can be a bit sloppy and and in consistant dependant on how you push the throttle. Try driving with the auto stick if u stil feel a loss of power i would suggest its a bad pump. As was mentioned you can buy a Johnsons pump for under 200 dollars. Needswings.com eurocharged.com supply them

Its up to you. Even if you have th dealer do the oil change, it'll probably cost you less then $200 to do the oil change and change out all the filters.

4 years ago you would of had to pay near full price, unfortunately our car's value is down to about a 1/3 of the price. There won't be much reward trading it in. You may have better luck selling here on the forum when your ready. Like others suggested, have your pump replaced. The bosch is the cheapest and will last just as long as the others. Then get a needswings intake and really start enjoying that car. No more driving in D, put it in 1 and to the floor.

Hey Guys,

Thanks for ALL your help and advice, I really appreciate it.

To the last poster's point, I understand what you mean; the time value of this car is really poor to the new-buyer, but really good to the second hand buyer!

This is why I wanted to buy second hand. I actually got a very competitive deal considering its age and mileage. I think in time I will explore the idea of main dealer trade-in because some of them have already expressed an interest. Mainly down to it being black, convertible and an SRT-6 (so they say!).

I'm really pleased with all your quick replies and the new information I'm now armed with when taking it to the service dealer. I've actually had a look for an Intercooler Pump replacement but can't seem to find a great deal of readily available one in the UK.

I'll keep you posted with how this goings.

Thanks,

Andy

if you want something a little more reliable, i would go with the johnson pump. Most of us on the mb forums upgrade to a johnson pump since its flows a little better and is more reliable then the bosch pumps.

Sorry to burst your bubble, but their interest in a trade has nothing to do with your black 'vert and everything to do with them wanting to make money on a car deal. If they're like most dealers, you'll get a lowball, insulting offer and then they'll send it off to auction house. You have a great car -- read up on it in this forum and enjoy the ride.

If you want to know if the s/c is working, push the pedal ALL THE WAY to the floor. There's what everyone calls a GO button under the accelerator that makes that car scream. If it doesn't, especially if already warmed up, then you probably have the dreaded and common s/c intercooler problem.

I wouldn't immediately jump to the conclusion that your intercooler pump is bad.

I noticed no one really mentioned how the supercharger really works in our cars. The supercharger is not always engaged. Mercedes did this most likely for better fuel economy while you're putting around town.

The supercharger has a clutch that engages the supercharger at approximately 2,300~2,500 RPM. One way to easily test this, is to pull into a big empty parking lot - roll down the windows and using the autostick, put the car in second gear. Bring the car to a complete stop. Then starting out in second gear, slowly accelerate. Before 3,000 RPM you'll hear the supercharger engage. You'll also get a little surge from the car when it kicks on. It's not extreme throw-you-back-in-your-seat kinda surge, it almost feels like the transmission just shifted gears. Also, a safety measure was built in so that if by some chance the supercharger is NOT already engaged by 3,000 rpm, it will not engage above 3,000 because this would put a sudden snap of torque onto the belt which would be bad.

If it does not engage, then you know you have a problem. The most common problem is the intercooler coolant pump. I've got 16,000 miles on mine and haven't had to change mine yet, but there are others that failed at less than 5,000 miles. So take that for what it's worth.

I had a sensor go bad as well....but the pump is suspect, the temp sensor for the s/c is suspect...people who have never riden in one of these cars wouldn't know the difference whether the s/c was engaging or not...try to find someone in your area that has one, and take a ride...there is a huge difference when its working...this car should setting your butt back big time...if its not...check out what everyone is telling you...
