Group Buy on Crank Pulley!!
Hey Guys,
I've been in contact with Omey at AMS.
He's willing to have a group buy on AMS Crank pulleys.
The original deal was to include headers too but they are no longer being made.
I have the Crank pulley fitted for over 2 years with no problems whatsoever. All I can report back are good things.
I have no affiliation to AMS. A couple of members have pm'ed me and asked about it and whether a GB was posssible.
Well here it is!
You Guys need 4! Yes only 4 members to qualify for a price reduction. I'm told $450 is the price, a saving of $50.
When I bought 2yrs ago they were $600. So go for it!
You can nominate a member to go through or go direct as a group and tick your names off a list.

I'm interested. Just need to do some research and ask a few people about it like PowerChip and see how it will effect my current ECU tune. I also need to do some research on how it will generate power, how much, and in which band. Unless someone speaks up it will probably take me a week to look this up because I don't know much about engine mechanics.

99CLK320,
Last time I talked with AMS the pulley kit sans crank pulley for the 320 claimed 6-8 rhpwr or 2-3 hrspwr to the wheels for around $400. I don't think there ever has been a crank pulley for the 320. the main idea behind reducing the diameter and weight of the crank pulley is to increase the rpm on sc on the compressor models. I can't imaging it would do jack by itself on a non compressor motor.

DLB, what I read is that it's the same diameter as the original just it's lighter and free spinning so because it spins easier you get more HP.
Can anyone verify the 320 HP gains? Is there a POC to contact at AMS to gather this information for any Q/As?

You are correct Jimmy. I guess I was thinking of the pulley kit which are smaller diameter than oem. WRT to the crank pulley, the link you sent me states that there is a 60% reduction in the mass from the oem pulley. That would make a miniscule reduction in the overall weight of the rotating mass i.e. engine, transmission, driveshaft, differential and axles. I'm not an engineer/math dude but I have to believe that whatever weight reduction there was gained would calculate out to a fractional horsepower gain at best. If you built a full on racing engine with lightweight titanium connecting rods, reduced the weight of the flywheel etc., etc. ad nauseum then and only then would a lightweight crank pulley be part and parcel to the overall gain and worth the money(to me). Take a look at the new McLaren 3.8litre MP4-12C twin turbo that produces just short of 600 hrspwr. Now that is an amazing engine. For a daily driver application, I'm not buying the hype and I don't believe a reduced weight/aluminum crankshaft pulley is worth the money. JMHO.

Seems the principle of this mod basically moves/shifts HP from the Crank to further down the drive train and in effect increasing RWHP. Guessing the question and debate is to what degree or % vs cost. What is the ROI?
Correct me if my understanding is wrong.

Hello,
Thank you for your expressed interest in AMS Performance products.
Certainly, the AMS power pulley for the V6 application will produce up to 15HP/TQ at the crank depending on modifications and base engine power.
All of our dynos are for the 55AMG, but the net gains on V8s are over 20HP/TQ for the V8 applications.
There are no compatibility issues with our crank pulley design with the evosport accessory pulley system. In fact, dozens of our customers have run the combo without any issues and have been very happy with the performance results. Just remember when you get a new belt to get the evosport size rather than the standard size (as it is a different belt than stock).
Other then that it is a straight forward swap. You may order the pulley directly off the pulley page on our website.
Hope that helps,
AMS

99CLK320,
After reading the E500 forum the first link on your list you still think the jury is out? Come on Jimmy. Yer a smart dude. We all want our cars to go faster but this one ain't the way. I'm gonna buy one of those intake tornados. Yeah! That's the ticket. If they will give you a money back guarantee, go for it. Buy one and install it and do a dyno after the fact. You have your pre dyno tests post Powerchip, no? Go for it. Its only money.

Since the outer diameter for the aftermarket pulley is the same as stock, the only way this product reduces drag is by reducing weight. Reducing pulley weight is not something new for automotive manufacturers. Neither is centralizing weight (commonly done on flywheels). The problem I see with attempting to centralize weight on a pulley is, compared to a flywheel, there really isn’t much to centralize.
For those that don’t know, centralizing weight on a flywheel works the same as it did when we were all kids on a merry-go-round; move to the center and less power is required to turn it, so it moves faster.
At any rate, this aftermarket manufacturer claims their device increased power by over 20 HP on an AMG 55. Somehow this manufacturer came across 20 HP that AMG couldn’t find. I’m having a hard time with this particular brand of Kool Aid. Mercedes-Benz has both a DTM team and an F1 team, these guys don’t overlook a lot – especially when we’re talking about the performance division, AMG, sleepwalking past 20 HP.
On top of that, I’ve personally installed lightweight flywheels on cars that I own. A lightweight flywheel does allow the engine to rev faster, it allows the car to accelerate quicker, but it does not increase peak HP. As clearly as I can say it - a dyno will NOT show a difference in peak HP by changing flywheels. I can site several flywheel manufacturers who say the same thing. I can site machine shops who say knife edging a crank doesn’t increase peak HP (this also reduces rotating mass). Make the engine rev faster? Yes. Increase HP? No. If a flywheel can’t do it, how can this manufacturer claim a pulley can? If this manufacturer said ”it makes the engine runs smoother” or “the car has faster acceleration when exiting corners”, there is a chance of some validity - a small chance because there really isn’t much mass to begin with. But they didn’t say that. They said “20 HP in an AMG.” I am highly skeptical. Of course, I'm skeptical of many things.
And that’s just the performance part. Lets not go into what happens if that damper doesn’t work as advertised.

99CLK320,
Many would like their cars to go faster but don't have the bucks to buy the real big improvements and wish for something magical. I'm one of them but common sense wins out.

I've read that in another post, someone else said the exact same thing almost verbatim. So in a way it's like how the Sprintbooster does not increase HP but allows us to accelerate faster. My interests has just declined but for argument sake here is another email I got from AMS.

Hello,
It took nearly 2 years of R&D and testing before the pulley was finalized for production. Many of our customers have had AMS power pulleys on their car for over 4 years now without a single hiccup. The Power pulley is designed to be as close to the OEM design as possible, the only difference is weight. Its actually much safer for your engine than accessory pulley systems (which over time create more internal damage).
The warranty covers the pulley for free replacement should it ever need be replaced. With that said, none of our customers have ever had to use the warranty policy because none have failed. As long as the pulley is installed properly by a certified mercedes specialist (THIS IS VERY IMPORTANT), then there should not be any issues at all. The only way for anything to go wrong is improper installation, so if anything goes wrong it will be the liability of the installation shop at fault.
Thanks,
AMS

Hi Guys,
I started this post on behalf of a few members here.
My honest experience with the AMS pulley is that it does work. To what extent I'm not certain but I'm happy with mine.
I got their headers and pulley at the same time and together with a tune I made 30hp. I asked the dyno operator how much the pulley gave and he said 6-8hp. I wouldn't feel much by itself but it makes a difference added with other mods.
I drive a CLK 430 with a 55 AMG conversion. I noticed mostly that my fuel consumption went down (I used to get 210m to a tank now I regularly get 240m spirited highway and city driving).
Also my engine smoothed out and the car accellerated quicker.
I did a test with a friend not telling him about the mods and asked him to drive it just so I wasn't getting a placebo effect. He said that the car felt quicker so I told him about the mods, which he said he could definately feel.
Anyway if installed properly you won't get any problems. I've had mine on for over 2yrs and I drive my car hard.
Hopefully I helped with those undecided.
I have stated in a previous post which I shall repeat. I have no affiliation to AMS.

That's what ASP told me about the underdrive pulley kit also. 6-8hp is at the flywheel. That translates to 2-3hp at the wheels at best. Is it worth the cost? I think not however, I would be willing to wager that the majority of your gains came from your headers not the 60% reduced weight of a pulley that might weigh in at 10lbs oem.

Pauljay, Hows the damper in the pully? because honestly like MracusF said thats what worries me the most and thats why i just never got into the whole pully deal and always like to keep thos factory oem. just have had bad experiences with changing the weight and the ratio of the puulies in the past.

I think that sums it up, someone correct me if I'm wrong.

the diameter has to be the same but the weight is different which will through the balance off if not designed properly. and i have to say i completely agree with MarcusF that pullies do not add HP unless they are the supercharger pullies, but if lightened they will put less pressure on engine and increase acceleration, but again Pauljay says he has seen an increase in HP and his word is very credible to me we just have to see if it was after the pully install or he had the heathers too. My concern is exactly the same as Marcus's the damper. which I Highly doubt has as much research and testing as Benz, which can result in very heavy repair bills. but again i can be wrong and they can have the greatest product.

Same thing is said about the Sprintbooster that it increases acceleration but not HP but yet most have spent the $300 for it. But at the same time I'm guessing there is less possible problems with damage to the engine with Sprintbooster as well.
I think this thread is turning out to be very positive, allot of good information from different sides and perspectives without all the yelling and screaming that was going on in the other threads about the AMS Pulleys..
I have to admit that this W208 Forum is the most civilized forum out there. lol

I really want one of those sprint boosters but im stillrunning on the 320 motor and i dont want to get it yet since i'm doing the 55 swap, and im not sure if there is a version that works with both. so all you sprint bosster experts please chime in. thanks.

Since the SP is on amplifying a signal to XXX, can't remember if it's to the ECU or TCU so you would use the SB for that..NO??? I can't remember the specifics on what it is amplifying and too busy at work to do the research. Maybe someone with more time can chime in.

Hello Jimmy,
1 - Yes, AMS has a 30-day moneyback guarantee on new-in-box pulleys that have not been opened or installed onto the vehicle. Once it has been installed there is a restocking fee for a used pulley.
2 - Sounds like you have a very strong 320 motor with that mod list. The AMS Power pulley will certainly improve the performance of your vehicle. It is impossible to predict exactly what the gains will be with your exact setup, they should be strong gains. The biggest gains are in 1st & 2nd gear so its impossible to truly dyno the full potential of the gains as nobody dynos the car in those gears. However you can view independent dynos on our website to see the gains some have achieved. The biggest improvements will be in torque in gears 1 & 2 (and 3rd gear as well although not as pronounced).
Hope that helps,
AMS
