UPD racing converter

UPD racing torque converter.

I bought racing high stall converter from
2003 - 2007 UPD MERCEDES TORQUE CONVERTER- 3000 STALL for 722.6 transmissions

I wanted higher stall speed 5000rpm so I payed 1200$ for this converter.


After I installed it and would test drive so there was no difference at all to the stock converter.
With the brakes were stall speed at 1700rpm and with trans brake at 2400 rpm.

I opened the converter and suddenly saw that it was completely stock, just like my stock converter from 270cdi.

I contacted the UPD but they claimed that if you are unskilled, you can not see the difference between stock and racing.
Probable they did not know that I am workning with a mercedes trannys and converters.

Then I sent the pictures to them of my stock converter and their converter and after that they have been completely silent and not heard from them ever again.

I can explain why their converter provides higher stall speed on the V8.
Because they use 11 "converter from inline and V6 engines that are smaller in diameter and has higher stall speed then the V8 converter.

You can get even higher stall speed by using 202 serial converter that comes from the 4 cyl engines.

They have, however Installed multi-clutch pack for luckup as it is available for purchase at the Mercedes. The only problem is that they have not shims the clutches crearens so that the clutch pack was completely immoveble With No clearens at all!

Here you have some thing to think about before you order UPD racing converter.






here is some pics from our converter workshop.

I just send my converter for a repair at the shop. I asked the guy if he could do something to it to improve the stall. He told me he could make a 2
"trick" that will give me 800 rpm more of stall from stock.

I wonder what this trick is... so i asked if the repair including the stall will mantain the warranty, he said yes.

Do you think using a smaller converter makes a higher stall?

This is interesting.

What converter is in the 32 kompressor drivetrains?

What is this 202 serial converter and what does it fit?

I bought a 2nd hand UPD converter and installed it in a SLK32 AMG. the converter raised the stall speed to around 2600 foot brake stalll and the lockup clutch engages more firmly.
