S/C Pulley, whats the real deal.

[ChrisA]

Thanks Jules, good comments

I had a new tensioner also fitted last month along with the S/C pulley. New belt now fitted and the German technician stated that the belt should last around the 10,000km mark even with mods.

I agree, it's a nightmare for all involved but need to find a solution.

First off, Eurocharged advertise Stage 3 as 642bhp which is what I had hoped to get near. With the Car not accepting the 82mm TB, issues with EC S/C pulley (2nd one!) I'm probably around the 600-610bhp figure. That is where I'm happy to be as after the first part of the install (Kleeman Headers, 550 injectors, Awesome Exhaust system) the car was running sweet.

Plan now is to get the car's Sub-frame straightened out, then get the car back to how it was before January

Hopefully that will be the end of it and no more sleepless nights!

In terms of power upgrades, there were and still are quite a few guys who constantly push the envelope of 55k in the UK: SavMan, Steve Bez, Ricky_S, Cliff with his Brabus SL. I think pretty much all of these guys are pushing north of 600 HP. Then there was Scorcher's E55 that was later owned by another forum member. Quite a few new 55 guys here are considering the Weistec SC upgrade so it will be interesting to see how far these engines can go. One thing for sure, 55k is very far from being irrelevant.

My point was purely about Reliability at 600 plus. None of the guys you mention have achieved this.

Based on this, if I had wanted more than the 580 I had I knew that I would be stepping into grounds of unreliability, which for someone doing 25k miles a year was too much of a risk.

Good to hear that you can see light at the end of the tunnel, but your comments also echo my thoughts.......

Don't advertise something that can't be delivered or isn't fully proven in the UK. A package should deliver what it says on the tin, if not then back to the drawing board, and instead offer customers bespoke upgrades (covers your ****). Not your fault as a customer and at least EC UK are doing all the right things to rectify the situation.

Historically the upgrade path regarding both crank Vs SC pulley on the 55 platform has not been without its problems.

The crank when letting go caused serious damage and most would not touch them with a barge pole because of this.

Then the early adopters of the SC started having problems, this was then fixed with manufacturing upgrades, now it seems the crank pulley issues of the past have been resolved and more upgrades seem to be going in that direction.

Having recently gone the SC route I am very happy with the results, the map impresses me more as the car seems much smoother at the lower rev range, and neck snapping when standing on it.

However it still needs to be a reliable upgrade for most users.

For most 550bhp seems to be the line in the sand as over that point reliability issues tend to surface, and that statement is in no way a criticism of those pushing the boundaries, to those that are or how do the rest of us learn.

Jules you hit the nail on the head with advertising something that cant be delivered. However the route Chris went must have been tried and tested in the States.....Eurocharged are massive as you are well aware in the Mercedes tuning world so surly the likes of the Throttle bodies have had hundreds of hours testing etc.
It will certainly be good to see Chris and his car all sorted and delivering the sort of figures we are all expecting......I am sure it wont be long and his unfortunate situation will be resolved.

Its a strange one with the Throttle Body upgrade, some cars have no problems at all, whilst others its a nightmare throwing up fault codes.

W have one in right now with the throttle body issue.

Its normally because some use Mercedes and some use modified Audi TBs and adapters, either way both need to be calibrated

Mercedes sell a 82mm and fittings albeit you will pay more unless you can find a used unit, as these where normally fitted to the SL55s with PP

Most CLS55's not sure about the E55s as these always seem to be lower, that are running fine with no faults will normally hit the 550BHP mark without any aftermarket parts and just a tune, the main thing that seems to increase with a S/C pulley is torque, I gained very little BHP with the pulley, but loads more torque, depends what your ultimate goal is, but I think crank, colder spark plugs and remap, and you wont go wrong, anymore then it would be the weistec for me...

Don't forget additional cooling. It's a must IMO if you are tuning the 55 engine.

When we fit the SC pulley we use the following method

After removing any existing pulley we ensure the shaft of the supercharger is cleaned and free of any burrs/marks/rust which will cause the bearing to catch. A light rub with soft abrasive pad is normally all that's needed.

Heat the inner wall of bearing gently with a heat gun

Spray the shaft liberally with brake cleaner to lubricate and cool the shaft.

Line up the pulley square to the shaft and the pulley should simple slide on.

Wasn't that easy with mine though was it Paul?

Yes it was, I think you are confusing a few things.
One the removal process which if heating/cooling doens't work requires the pulley to be removed with puller. Two the symptoms that you felt were directly linked to the pulley were actually diagnosed as both an internal failure of the inter-cooler and glycol contamination of the transmission.

 

[BenzedUP]

Waste of my time.

Hi Paul

Dropped you a pm and email earlier - not sure if you seen it let, sure let me know

 

[SavMan]

Wasted my time.

I'm sorry you feel that way, we simply replaced your bearing free of charge even though it was not fitted by us in the first place. At the time we told you that we could see signs that your intercooler was leaking, later you had a gycol test carried out which also confirmed that your transmission had gycol contamination.
Neither of these are related to your pulley.

 

[BenzedUP]

Yes nothing to do with that Paul it's honesty and customer service where you need to look at mate.

I won't say too much on here anyway I'll leave it at that, you've got my number if you need to discuss further...

As I said I'm sorry you feel we didn't deliver to your expectations and of course I will give you a call to discuss.

 

[Idracab]

Not wanting to get involved in any ones argument but I have to say that I have had a few bits done with Paul and Andy. I can honestly say that the service level I have received is second to none.

I had a service carried out. Andy came to my work place to collect my car, leaving his personal car with me to use whilst he carried out the work.

I had my TCU upgrade done with Eurocharged UK. I took my car to them and my TCU was an older version that required a specific map from the US and couldn't be done right away. The following day both Paul and Andy came to my work, removed the TCU took it away and returned with the remapped TCU and refitted within a few hours.

My alternator failed this week leaving me stranded. Spoke to Paul who answered straight away and gave me clear concise advice on what to do. two days later Andy came to where I managed to park the motor, removed the faulty alternator and has taken it for refurb. He will come back Tuesday morning to re-fit.

I can honestly say, I would not use anyone else to look after my MB.

Just my 2 pence worth.
