tell me in your opinion the best 180mm CP is.


weistec ? evosport ? Ec?




another question is ...do all 180mm cp makes same power ? if I were to swap say ec to evosport would I need a re-tune?

Hulk

180 is 180

Best IMO is ASP pulley

Ls1toAMG

I would go ASP or Sharduls pinned pulley. I would pin the ASP just for piece of mind

My car is around 60k miles on the evosport 180.

Unless it's built off a non-harmonically balanced (preferably MB OEM) core....

Unbalanced pullies are false economy.

ASP is a really nice one. The new aluminum outer ring designs have 6 locking pins for absolute strength.

Yes, asp can use your mb core

Dat Boy I

Asp with zero issues 3+ yrs runnin the beast.

this is my next mod. Does asp make a 185mm?

I hope their pullies are better then their website LOL.

How do the locking pins work? I thought there is just one bolt that holds the assembly on.

dchl21

anyone has weistec ? any belt problems on any of these?

Hulk

Yes asp makes a 185. Mine has one bolt. Been on since before I bought it. Install is very important on crank pulley.

m3j0n

so what is the 6 locking pins that is being mentioned? What exactly is the special install on the crank pulley? New bolt, obviously, but what else?

hulk, which size ASP are you running?

Hulk

Nothing special about it, just got to install it right. Majority of pulleys that fail is because of bad install. Use someone who has done many crank pulley installs
The bolt should be torqued to 200nm(148 foot/pounds) and wait for 20-30 minutes then the bolt is turned an additional 90 degrees to lock/stretch it.

Make sure it's aligned with the keyway because if it's not you will lose that pulley.

Use a brand new bolt


The keyway can be shredded easily and then you can be in trouble.

m3j0n

Thanks for the tip!
where did you have yours done?

TheTherapist

I got lucky and scored an MKB for $500 as it was their last one from old stock. It uses the oem harmonic balancer same as asp.

The oem bolt is a one time use but there are hex bolts available now (for 3 times the price) that can be torqued even tighter and are reusable.

Hulk

Mine was done by Wade at European specialists in Wellington from the previous owner. Many guys have gone to him for crank pulleys and never problems. He was a master tech and foremen at a Benz dealer then left and opened his shop years ago. He still gets calls from dealers to help with certain problems.

m3j0n

sweet... can I use you as a reference?

TheTherapist

Just don't make him angry - you wont like it when Hulk gets angry...

m3j0n

LOL....

Hulk

lol

Pm me m3jon

ASP 185 here as well and what Hulk says is the ABSOLUTE TRUTH!

SterlingE55

As these cars get older and have more miles be cautious of building an ASP pulley from a high mileage core.

Toadster

one that doesn't fall off

draggbody

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...



you can see the orientation on the block here

StarvingArtist

Brilliant! I like that system much better.

Shifter

Why would you say that? I think that would be much better than transferring all that twisting load through the crank like your tool does.
