Sl60

[talbir]

With the engine/car confirmed as an SL60, a few things still don't make sense...if it's pushing out 381 bhp why is it struggling to perform any better than a stock sl500 ?

What drivetrain loss assumption was made in conversion of the dyno outputs ? Can you give us the read-out from the dyno please, which would be RWHP not crank HP ?

Biggest question is how is engine performing to this level without the correct LH module and EZL ?




thanks

I am still confirming a few more things but the deal breaker of is it or not has been confirmed. A stock SL500 should output 322 BHP/ 326.5 PS I am told so the SL60 is a fair bit up on this and I still think there is more to come. The SL60 output 376.0 BHP/381.2 PS so it is up about 17% on the SL500.

Can anyone with an SL60 AMG confirm for me if they have the HWA LH & EZL modules? It is really easy to see after taking the engnine management box cover off. I unscrewed 5 bolts and it just lifts off. My pics for this are on the website www.sl60amg.com

Thanks

I am told by my specialist that inspected the car that this is older technology and wouldn't have applied to this 1997 car.

Fantastic news! :bannana:

Even with the bits and pieces that you need to do, you still got an absolute bargain of a car.

Makes the £24,995 SL60 seem...well...overpriced??

 

[IanA2]

Do you have a code 808 on the VIN? ie "Change of year of model, last figure shows new model year"

Mine is a 97 Reg (R) but a 98 Model Year.

So, it looks as though it is the real deal, all that's needed now is to get it to run like the real deal!!

 

[talbir]

Aa yes, i keep forgetting it's a bloody 97 car....i don't think about MBs existing post 95 !

Yes, in which case it would have the Motronic ME injection system not the LH!

But, i would expect the ME module to be tweaked to feed the increased displacement, unless the technology meant it could adapt to 6.0 without reprogramming.

Apparently from 96 onwards, every SL60 AMG came with the full styling and engine package. Pre 96 cars were availble with just body styling and wheels.

So all seems ok, except the actual performance....why is it not different to an SL500 on the road ?

Agreed Setanta...very good buy....but it was a bit of a risk as none of this was confirmed when I bought it. Was touch and go if it was an offical and genuine SL60 AMG for a minute!

Does anyone have the model as 'SL60' or 'SL500' in the glued in Data Card in the very back of the Maintenance Booklet? Mine says 'SL500 Roadster' but the engine number on the data card is the correct AMG engine number.

I think the £25k one is pretty expensive if you ask me. I am sure it is tons better than mine but mine isn't bad for a 13 year old car at all. Not sure it is worth over twice as much as mine. I certainly couldn't justify paying that for it!!

 

[IanA2]

I don't know where in Herts you are....but I'm near P'boro and would be happy to meet you half way say to give you an idea how it should perform.

Talbir...it was driven last night to put some BP Ultimate in ready for the dyno run this morning and popped a few miles down the road while out. This is the first it has been driven since the test drive last Sunday. It felt like a different car I am told, maybe due to the 3 hours run back from the sellers had helped give it a clear out.

The car has only done 10k miles in the last 6 years with the last owner and has not been driven much very in the last year at all. My guess is the adaptive settings for gearbox/engine was making the car seem a bit sluggish and not much quicker than the SL500. After a good 3 hours run this seems to have helped as the car was almost dangerously quick last night and certainly much quicker than the SL500. Also very different and quicker/more responsive than on the original test drive.

 

[IanA2]

was almost dangerously quick ...

yup....thats the 60

Based in Potters Bar....so happy to meet up at some point....might need to wait a couple of weeks though as we just had a second baby and I will end up being in the dog house!

 

[nick.ged]

followed this thread with interest... wot a palava

but happy ending, :bannana:

well done.

 

[stats007]

Seems a few members can create mountains out of molehills . I'd have been happy with Olly's word to be honest .

New MAF and lambda sensors should make a difference to the performance.

 

[talbir]

Stats007...the only entity to confirm that it was an SL60AMG was MB themselves....i don't recall Olly or anyone else for that matter confirming the originality of this vehicle as a genuine SL60 AMG ? If so, why was the new (and previous) owner searching frantically for the confirmation all week long ? And where were you this past week to help in the issue ??

I don't recall you adding any words during this past week to the thread ? Next time put your money where you mouth is and participate at the point of need, not come in right at the end when all is done and dusted.

I would still like to see those dyno charts...

Lol,that`s the right reply. Stats007:If you`ve viewed this car as you state you did and also made an offer,how come you as a 129 guru could not see all this.

 

[rockits]

In all fairness to Olly his task was to professionally check over the vehicle and make sure there were no major issues. I never asked him to confirm if the car was a genuine SL60. I thought it was and was happy to take a punt until it was confirmed. Olly did a good job and I appreciate his work, time and efforts. I don't think I have been overly cautious or fussy here as anyone would look like a bit of a plonker if they bought it and years later it was confirmed as a non-genuine SL60. A good exercise though and it seems a few of us have learnt a bit.

Seems almost comical though that 4 owners and 13 years passed before anyone realised the wrong engine numbers on the key docs!

Well pleased with it though and looking forward to a long and happy ownership.

Sorry, I must have clicked the button twice on the last post. It was on my phone so not as easy to use as the laptop!

I'd have to disagree with you on this one Stats and agree with Talbir. Why would I take the word of Olly(admittedly a knowledgeable MB man) as to whether he thought the vehicale was geuine? Surely it has to come from Mercedes or AMG to confirm this. Although it was always unlikely with the obvious and expensive changes to this car that it was an SL500 trying to be passed as an SL60 AMG it couldn't be ruled out until Mercedes or AMG confirmed the authenticity. Also due to the very genuine history and straigtness of ownership to date it seemed weird on that point alone. However it needed MB or AMG confirmation.

I will scan in the Dyno chart and upload it to www.sl60amg.com tomorrow for your info. Would be interesting to see if there any improvements of changing spark plugs, coil pack, the lambda sensor(Olly said showing a fault) and cleaning MAF. Might do another Dyno run after all this is done in a month or so.

The car doesn't seem quite as sharp to turn in initial as my ADS equipped SL500 but the ride seems much better and more comfortable. Something I expected to have been the other way around. I do have the SL500 on the lowest and hardest setting all the time though. Pleasant suprise though as the SL60 rides very well and is very comfortable.

See all what? A DVLA error with an incorrect engine number - nothing else is untoward?

AMG/MB records are notoriously poor on these cars - a little bit more rationality rather than jumping to wild conclusions would have been more helpful .

I don't recall you adding any words during this past week to the thread ? Next time put your money where you mouth is and participate at the point of need, not come in right at the end when all is done and dusted.

I've been working away so apologies for not being here to point out the errors in your statements in the last week - like not even paying attention to the year of the car in question .

If you recall I also offered to put my money where my mouth is on the 500E discussion but you backed peddled out of that one .

No-one has back-peddled at all...you think you can outdo a 500e, come on down anytime.

The only back-pdealling has been you this past week....when it came to crunch knowledge requirements, you went silent.

Not for the first time you resort to weak comments when it comes to technical debate....your history of posts is littered with such examples. You just cannot cut it when it comes to the crunch....either you go silent or you take cheap shots.

As the owner has just confirmed, Olly only confirmed it to be a car in the condition acceptable to buyer....nothing was confirmed as to it's status as an SL60. Either accept your error or go silent again.

I`m afraid that`s not an option as he always likes to be right.As for the 500e thing Can`t wait
