yes sir

 

I’m surprised by the fear and negativity re: dynos around here. Provided the car is strapped down properly and provided with proper cooling, it’s hard to see how to damage the car on the dyno doing anything that wouldn’t similarly damage it on the street. It’s just a big drum providing rolling resistance the same way the weight of the car + the air provides resistance on the road.

Not opining on the shop’s responsibility here - best of luck to the OP.

 

Ammein, what are your options with rebuilding the transaxle? I posted the link to Albert Motorsport in Germany-consider getting a quote with shipping, regardless of who ends up paying for it, so you have an idea what your options are. I don't think many Porsche Dealers rebuild transaxles. As I've seen, with new cars in the warranty and extended CPO plans have transaxles removed and sent out for exchange-consult your options there with the Porsche Dealer, and ask where do they send them. The link I posted also has upgrade options for GT2 transmissions to handle the extra torque and power in tuned cars-

* I had posted asking if you have receipts for maintenance, the goal would be to see the work order details for when you had the car worked on-if the gear oil was drained and replaced with the correct viscosity and type-and whatever oil is in there now should be analyzed too.
And, you have to see which section of the transaxle was damaged-but once the differential had an issue the whole thing would have probably had particles traveling through the oil, and only a complete teardown will reveal what went on.

Exactly. Logic. And logic states that the only way they could have damaged the car is from the dyno test, and you were there when they did it. Everything outside of that means nothing. My old GTS had the transmission replaced at 10k miles, and that was just a daily driver. It sucks when it happens.

Did you get the work done at the Dubai office? I'm not familiar but somebody should reach out to them to get their side of the story.

 

If you noticed something wasn't right you should have turned around and went straight back.

 

So what were your dyno results? As mentioned, there are places to beef up a transaxle for extreme power and torque-
Having said that, I think people that build street cars for drag racing and 1/4 mile should just start a career in drag racing and see if they can work their way up to top fuel, none of these cars were meant for this 😂

But, since you did have damage, and need closure in what has happened, post your maintenance records, what happened on the dyno, oil analysis and teardown of the transaxle to see where it failed-as soon as people start tuning cars for insane power, they should be able to assume the consequences if parts fail-

 

Bloke gets a dyno tune and now we’re acting like it’s a single turbo Supra on E85 gunning for 1000whp? Oh my

First of all, if your going to come on and try to defame a company because you want your maintenance bills paid, at least state some facts.

We advised to you from the beginning that we did NOT want to tune your car. Emre told you on more than one occasion that the car is high mileage and there is no warranty on any parts, either engine or transmission.
After you continued to insist to tune it and accept that you will be responsible if anything goes wrong, your car was tuned.

The car came to us on the 13th January 2023. You had your issues some time later and had the car looked at, in the end of Feb 2023.

You ordered parts from ES and had another garage fit them. You also purchased separately and independently from us your own chosen upgraded clutch, which the other garage fitted.
This garage couldn’t fit the exhaust so you asked ES DXB to. The Exhaust was fitted by ES DXB without an issue and you wanted to tune the car on the dyno.

You were present at the time of the exhaust being fitted and oversaw all work on the car. You were also present to see the car being loaded on the dyno and present for all dyno runs.

When the car arrived the clutch was extremely heavy and difficult to engage. This was advised to you and it was indicated that it may have been installed incorrectly as a clutch with that heavy operation had not been experienced before by anyone, including myself.
You accepted the car had an extremely heavy clutch to use and this was something you said you will take up with the garage who installed it.
At the time I told you as well that when you are driving fast on the street, be careful with your gear changes as with a clutch that stiff it would be super difficult to change gear quickly without crunching gears.

The dyno used is a Mainline Hub dyno. This operates by attaching the rear hubs to the dyno separately. The rear differential or synchros cannot be damaged as we run the car in one gear from low rpm to redline. We operated all the runs right in front of you without any issues at all. We have video’s of all the runs and there is no cutting out of the car on the dyno. The car was not over revved or forced into gear. I was operating the dyno myself just as I do myself with every car in the UK.

According to your damage report, the 2nd gear synchro, 4th gear synchro, the actual 3rd gear and 6th gear are all damaged.

How can the 6th gear be damaged from a dyno run in 4th gear?
the synchro can only be damaged with forced shifts, which would be probably from you shifting the car on the road without engaging that very stiff clutch properly.

The diff flange is also broken, this is not possible to break on this type of dyno. There is no wheel spin, no straps, just bolt onto the hubs and go.
We have ran Porsche’s with upto 1700whp on the same dyno without issue. Even a 2200whp Huracan, and none have ever had any issues.

How can a car have multiple synchros, gears and a diff damaged from a dyno pull? There is no technical report at all to back your accusations.

Where does negligence come into it?


The car was tuned without issue, made good power and had no issues apart from the extremely heavy and stiff clutch that you were already aware of.

You continued to drive the car away that night and were very happy with the results.

We have not worked on the transmission or the drivetrain of the car. We tuned the car on the dyno and installed an exhaust, that’s it.

The report your garage provided was given to Bill Rader and another Gearbox specialist who both advised that it was impossible to be damaged while on the dyno. The Diff sustained damage that looked to be from launching, and as both experts concluded, it was something that couldn’t be from a few dyno pulls. The Hub dyno does not damage transmissions.

We shared Bill’s assessment with you and you wanted to question Bill’s credentials. Anyone on this forum would know he is the go to for Porsche transmissions and the most expert in the field of building them or assessing damage.


The car clearly had a drivetrain issue from before and you were well aware of the clutch not engaging properly.

Even after all of this, out of goodwill we advised we will provide you with a Wavetrack LSD free of charge as we didn’t want to waste any more time on the situation.

However your demand of paying for your full gearbox refresh just because we had your car on the dyno for 5-6 pulls is not reasonable.

We have continued to make efforts to resolve this privately, and your attempt at slandering ES DXB is not something that will blackmail us into covering your maintenance costs.

I’m not here to argue but state these facts. If you wish to try and continue dialogues then you’re more then welcome to continue via email as previously advised.

 

Thanks for coming everyone. Have a nice evening!

 

I'll be here every night same time through Sunday.

I didn't want to be too harsh on the OP, but I look at things that make sense.

Back in 2000 I used to import a CD player called the Ah! Tjoeb Njoe Tjoeb 4000. They were a modified Marantz where we put in a tube output stage. They had started at $549, with some options, and we sold thousands of them. They were known as a giant-killer. People still use them happily today. If they needed service or a new drive mechanism we did so for $169, and sometimes for free. The whole idea was to create buzz and new customers, not make money.

We had repaired one one for a dude, many years old, and in the golden glow I said "No charge". Four years later he came back and swore I said I would repair his 12 year-old for free next time. In fact, two guys gave my company a bad review after we did them a good deed with this CD player. Jesus.

 

My Dad has dealt with Bill directly on more than one occasion and I can tell you that the man knows his stuff very well, inside and out. I hope you get the situation sorted Ammein but you take your car to ES Garage for top notch work, nobody is perfect but my family has never had any issues with the Dubai location. The amount of damage you sustained sounds like a drive train issue, i.e. clutch, especially after driving it ~60km, it would have shown itself the moment you left the garage.

Good luck my man, beautiful car and least everything can be repaired.

 

And be happy that your problems can be solved with money because the day they can't..........

 

Receipts for maintenance were never posted, neither acknowledgment that the clutch had been replaced, or that it had a problem-lots of people responded with lengthy suggestions, concerns and speculation. Ultimately these threads are for the benefit of all, but looks like it wasn't very transparent-

welcome to the Dubai scene .....

 

watched the ES motor video….my buddy had an AIM 997 turbo….1000+ hp….we did a roll “race”…. it was like my car was going in reverse. insane.
