the stock keyway only engages the balancer about 3/8" or 10mm... my "first" 180mm balancer clearly had a crack where the keyway was because all of the torque is being held by the tiny amount of keyway... this is simply my opinion, but there is no doubt in my mind that the MB tool is ultimately what caused my failure... besides, 250ft-lbs is not breaking a crank... i mean the engine does make 600+ and the crank doesnt break, right???

I see the point f the keys way taking the load then when torquing it with the factory tool. However this is how it was designed and countless people have done it this way.
Yeah u are confused about that second part. The Pistons/rods accelerating the crank does not apply the force in the same way as a twisting motion like holding it from the he other end of the crank.

think about it... 250 is transferred through a 1/2" drive extension... do you really think that extension is stronger than an AMG crankshaft... i installed a crank in mine, its a freaking beefy unit... either way, i can never in good consciousness use or recommend the oem tool... it is a design for use in the vehicle... it is not installed like that from the factory...
we can agree to disagree about it...

Im gonna be shopping around for a 180mm crank pulley soon. Looks like ASP is the way to go. Does anyone know anything about the Eurocharged 180mm crank pulley??

Very Clever
Draggbody, is that the tool you were explaining to me when we were down at silver dollar? Looks mint and the concept behind it makes a lot of sense. Afterall, I believe there is another tool mb makes that bolts up to where the starter is mounted to lock the flex plate. I'll pm you some questions on the crank extension.
Does anyone know how much it costs to make a 180 or 185 ASP when you send them a stock pulley assuming they still make them?
i have the 180mm UPD pulley and crank extension from shardul... i had previous pulley failure so i sent my crank to BIP for repair and install the crank extension as well as do a full length keyway... i have put 2500 hard miles on the car since i reinstalled the crank and just rechecked the torque on the ARP bolt, still at 250ft-lbs... i will say that i will never recommend holding the balancer to torque the bolt... i built a tool that bolts to both of the torque converter bolts and interferes with the oil pan, it takes probably 15 minutes to recheck the torque on the bolt...

Has anyone had experience (good or bad) with Ultimate Performance Design (UDP) balancers?
Their website states that the balancer is designed and manufactured specifically for the M113K rather than from universal balancer/OEM hub which I believe the ASP is?
The price difference is negligible between the two options (both expensive) so I want to get one that will last and handle 600+bhp.

The UPD performance balancer is the only complete kit on the market and out specs all other competitors,as the UPD balancer is specifically designed for the Supercharged Mercedes AMG V8 and not a universal balancer hub that just adapts to your high performance vehicle`s crankshaft. http://ultimatepd.com/m113k-intercha...nk-pulley.html
* Hard Nitride coated hub, * Hardened Chrome moly CNC machined steel balancer hub VS competitors mild steel hub. * SFI approved harmonic balancer * Ultra strong, interchangeable, and hard annodized aluminum boost rings. The UPD high performance balancer is precision CNC machined in the USA and installs directly in place of the factory unit. The balancer and crank ring assembly weighs only 12lbs, compared to 15lbs lbs for the factory steel unit.

It is just a removal and replace of the existing so no change to the boost rings or need for a re-tune.
The ASP is new from ASP. I assume this means a new core??
Assuming the ASP is constructed from a new core, are the extra $'s justified over the UDP?
