Don't know much about this as I'm happy with my solid ASP pulley with the new steel hub but it looks like ASP, as always, is trying to keep everyone happy so if you want a Renntech Style pulley and can afford to fork over $200 and your old pulley they'll accomodate you! If you want the new solid pulley with the stainless steel hub it's $300 and the traditional all alloy pulley can still be had for $350. At least now I won't have to hear all whining on dampers, have it anyway you want!

Got any idea how much a factory pulley/dampener cost so I could keep my stock one on until the new one is done? Heck, there must be a bunch of stock pulleys out there by now that could be swapped out.

I am down for the stock add on ring.

But i need to fidn a stock pulley so i can still use my car. They should do a program where they refund u a core charge and sell u the complete pulley all done haha

When I bought a stock pulley, they were $302 at the dealer. I was able to get a 10% discount so I paid $270. Please comfirm the pulley options with ASP as I've heard about it from another forum and not from Lee directly.

Why only 10% on the pulley with the dampener? That's the one that probably everyone would want if it weren't for the lower boost.

I've never seen this addressed before, so I'll ask the question here. From an engineering standpoint...and for reliability reasons, wouldn't it be saner and safer to replace the Kompressor pulley with a smaller size to achieve the higher rpm's/boost? You'd probably end up with a better final result (think about the rear derailer on your mountain bike).
There are just too many variables and too much that could go wrong with altering the crank pulley.

hmmm. i would have them add on to my stock pulley except i think i will get the worst gain fron that and i dont think it would be worth the time and money.

Buellwinkle

That may only apply to Linh's car, an older SLK with a slightly different pulley, call Lee to double check.

Rick, yes, this has been addressed over and over again and I agree with you, that would be best. Here's the obsticle I came across, MB won't sell you that pulley unless you want the entire S/C assembly and that's a lot of dough. The other obsticle is that there's no room to get a puller in there so you have to remove the S/C to remove and install the pulley and to some that may be beyond their limited mechanical skills. Also there's the issue of the pulley remover although that's minor and that combined with the pulley would still be cheaper than a crank pulley. If you can get a car to Houston for a while I'm sure Lee will make it for you.

I have a question, I am debating between the c320 and the c230k, and I am wondering if they make pullies and other easy or popular mods for the c320???

Outland

Just look into mods for the C320 SEDAN...its the same engine as used in the C320 Coupe.

BTW, there's no supercharger on the C320, so no pullies to swap out to get more boost. If you want to have some fun modding your car, look around for a 2002 C230 with the 2.3 Supercharged engine. A simple pulley swap will give you more HP than the C320 and better mileage to boot.

With an '03 you can't modify the motor yet on either. You can get an underdrive pulley kit from Evosport for about 10-15HP on the C320 so if I was buying an '03 I would get the C320 hands down, that's a sweet motor. If you can get an '02 leftover C230 then that's the best for mods and power. With a pulley and K&N filter you will have about 10 more HP than the C320 and about 20-30 more ft-lbs torqe but a noisier motor but for thousands less. Check out the SLK forum, they've been having this argument for the 2 years.

Matt230K

In my opinion, choosing an SLK is completely different. On the SLK, I would much rather have a 320 just because of the great exhaust note and the engine seems to work so well in that car. But in the coupe, I am fine with the 230 and have no interest in the 320.

themindfield22

hey buell, the underdrive pullies sound pretty good, ,do u know if there is anything else, simple like that available for the 320, ,like maybe a fuel regulator or something??

Buellwinkle

Nothing that I know of for significant power at low prices. A catback exhaust and K&N filter are all that come to mind. Now if money is no object and many say that but don't really mean it, you can get a Kleemann S/C for the 3.2L but it will cost ya big time. Also Brabus has a 3.8L mod but that's even mo' money.

themindfield22

well, so far, the one thing that i know i WILL do for a fact is the "underdrive pullies by evo sport" that u told me about. I think they are worth it. I just need to find something else that's similar in hp gains to the pullies, and i will be fine. Like if i can get 15 more HP out of something else to make total of 30 HP gain, that will be just perfect.

Buellwinkle

Call Vadim at Sho Shop at 714.894.8415 and they can set you up with the Evosport pulleys and give you advice on hopping up the 3.2L. Tell him Buellwinkle sent ya.

So has the pulley shearing off problem been addressed/fixed? Does anyone still trust ASP?

Buellwinkle

My car had about 12 failures since new, should I still trust MB? MB has been known for MB pulleys failing on some cars, has that stopped people from buying MBs? The pulley is a customer installed performance upgrade and some customers unintentionally install it in a way that may hasten it's demise. For example some people have been sanding their hubs to make a nice easy fit, ASP told me that they won't warranty these pulleys because the customer modified them. It's supposed to be a very tight pressed on fit and I've told people to use the bolt to ease the pulley in but people are very creative. Also what if someone by chance dropped the pulley bolt and the washers fell off and they put them in backwards, a very easy mistake, this would leave the hub edge unsupported and even possibly lead to a hub failure on a factory pulley. I still think it's safe considering that many people on the forums have over 12K miles and no trouble. This is why ASP will continue to make the all alloy pulley as he still stands by his original design and there's nothing wrong with it. But for those that have doubts they also sell a pulley with a stainless steel hub for added strength and they also now make a Renntech style pulley with a pressed on ring, not my favorite but some people insist on the factory damper so ASP accomondates them. Besides, ASP is not the only vendor to have had a pulley problem on the 2.3L motor, just the one with the most visibility because it dominates the aftermarket pulley market.
