AMG engineers are not idiots' the have an reason why the build the pulley like 2 Pulleys with an rubber damper in between to keep the force away from the crank and keep the SC Gearbox ......
and 2 Belts strait on 1 damper will make an strange Frequency on the crank.....

Here is some more data on our new pulley:

- Stock pulley is TUFF bonded by vulcanized rubber.. that's it.

- In comparison, some of the aftermarket pullies are pinned at different points around the circumference.

- Our pulley has 2 carbon steel pins that are preseed into the solid mounting section which are harder than the alloy pulley itself. The rest of the mounting is done by stainless steel hex bolts.. From what I was told, the pulley would disintegrate before the mounting hardware would.

- Torsional energy is absorbed via the accessories pulley and counter weight which is mounted on rubber

When can we expect them in USA and what si the color break down? I call dibs on the first black (friend) and red (mine).

I re-routed an extra 5 to California.. 15 pieces in total. 8 Black 7 Red.

They are coming from Europe so it will take a few days.

Ashkan's C43

will this work on non-kompressor m113s i.e. 210 e55 and c43?

*** UPDATE ***

*** PULLIES LANDED TODAY ***

Looks like Vadim had some fun unpacking all the boxes of goodies...

Nice job Vadim.... Reminds me of the game Connect4.. lol..

vrus

Forgot to mention one thing...

Anyone who buys a crankshaft pulley has an option to add our underdrive pullies for an additional $250!!!!!!

Here is a pic of our billet aluminum 3 piece underdrive pulley set.

Any Idea of HP gains with the under drive pullys?

vrus

It frees up a few hp.. nothing major but I think they are good for 10hp or so. I never dyno'd them separately to be honest..

I believe they underdrive the accessories by 11%.

Wow....those red ones are

Looking good Victor...e-mail sent...

Hope to see to Dyno results on those pulleys:

vrus

Glad to see you got rid of those ****ty button head bolts!!!!!! had a friend of mine with them on a set of adjustible cam gears that loosened up and timing advanced, and well lets just say the inspection hole in his block was not pretty! you can certinally put more torque on a standard allen than a buttonhead!!

vrus

It was a prototype piece that had those bolts...

Glad you like them!

what exactly does the underdrive pulley do....

Victor, does that $250 price tag for the under drive pulley's apply to the holiday special you and vadim are running also by any chance???

Vadim @ FD

Yes, we can also install them for you.

Any 32s pulleys on only 55s That red is hot I like that a lot.

Vadim @ FD

Install is $120.

Any dyno data on the pulley and with and without that underdrive? I didn't even pay attention to that part. How much more ummmph does the underdrive add? Can it be added later?
