Thanks so much for this, a great insight into accumulators! I've had such a nightmare trying to get them replaced on my SL recently but had Auto Accumulators refill all 4 for way cheaper than I was going to pay for the replacements. The SL has much larger accumulators than the ones you showed here as well (100bar of pressure) so I can't imagine 7.5bar is too much of a hassle for them? I don't know if you've been in touch but it seems refilling them might be the way to go
At the moment it does seem to be that the replacements are more reliable, we've not replaced any that we have already replaced at all and some are 5 years old so hopefully the ones being fitted now sort the issue.
if you don't replace the accumulators, and you're essentialy driving on track mode all the time, does that wear out the suspension arms or cause... cracks.. in the long run?
Thats an interesting question. First off with failed accumulators you're not driving in track mode as such, you're driving in a mode where the suspension cannot accommodate the wider ranges of volume displacement of the oil, so you're losing rebound damping as well as compression, what the accumulator does is allow for those wider varieties of damping control. In addition they are linked (there is only one system) so if one has failed the others in essence try to compensate but they cant really do it. In the early days of replacing these we used to just replace one and leave the others if they were fine but on the front if you did that the car would pull under braking as one side had the extra volume and the other didnt so it unbalanced the car. It would be an interesting test to remove them all and blank off the attachment and see how the car handle, want to try? :)
how long (in time) should we expect the accumulator on a 12C to last? I had mine replaced about 6 years ago, and now the suspension feels "clunky" again.
I understand the upgraded 720/765 accumulator is of more durable design but is probably too big to fit the 650/675. So is it possible for you to manufacture a batch of similarly more durable aftermarket version for the 650/675? I imagine that would be a popular upgrade.
There is no evidence that the piston version is more durable and it also has the downside that the car needs a software change to use them whereas the older version doesn't. We will continue to use the original version.
@@ThorneyMotorsport sorry for my slow response. However I am not convinced because if the original diaphragm version is better then why did McLaren switch to the piston version for their newer cars?
By the way, it’s been weeks and I am still waiting for a quote from your company for 4 (675 LT) accumulators. I was asked by your web staff to provide my shipping address and quantity to order but after I replied no one followed up with a quote.
Glad to see your back, I did get a bit worried!!! Thank you for sharing with us your knowledge and Witt...

Love your dedication to engineer solutions to the issue regarding these cars 👍👍
Another really useful video John 👍

Bonjour et merci pour cette vidéo ! Avez vous terminé la mise au point de vos accumulateurs "made in Thorney"? Quand allons nous pouvoir les acheter ?

@@Utahsaint yeah about 5-6 years is right

@@ministryoflies3300 new supplier that's all
@@ministryoflies3300 I can't see any emails that are not dealt with, perhaps if you can drop me an email I can look for you
thanks john
usefull insight
Great as usual!
Another expensive unreliable part by McLaren.
