Hi Guys

Dlbehrns

You could be right. When I had my pulley installed it was with the headers too. But like I said the operator did mention that by itself you wouldn't feel much.

What you will feel though is a willingness to rev faster and a smoother engine plus you will get better fuel consumption.

Thanks for vouching for me!

I took the pulley to a garage that I use and they commented on how light and well made it was. I did ask them about the harmonic damping on it (I did read other horrific posts on the AMS pulley when researching) and they said it should be fine and just to make sure that it was torqued up properly. AMS gives you the torque spec with the pulley, they also gave me an updated Mercedes Pulley bolt to install with the pulley. I guess Mercedes thought there to be a problem with the original!

Thanks also for the confidence vote and big-up for 55 conversion.

If you added the pulley to your other mods I do believe you would see a gain.

If all the small adjustments were added up you would see a big adjustment.


Like the sprint booster works by magnifying inputs so you don't work as hard, I believe the pulley being lighter makes the engine work less and so you see improvements however small they may be.

Hp may be small but the overall driving experience is good.

I'm sure AMS wouldn't mind if they recieved a resealed box in their returns post. Someone should take the pulley to their trusted garage and ask questions like I did.

I guess this sums it up.

1. $450 Group Buy
2. $500 Regular Price
3. Free International shipping
4. HP Improvements in mid range gears, no increase to Total HP
5. Improves gear shifts, allows the car to shift faster
6. 30 Day money back guarantee on new-in-box pulleys
7. 20% Restocking Fee for used pulleys

Hello Jimmy,

The crank pulley does free up engine HP & torque through improved efficiency which can be seen directly on a true loading dyno. View this independent dyno from one of your C55 owners as proof:

http://www.abedinmotorsports.com/dyno.htm

It frees up significantly more torque & HP in the mid range and allows the power to come on significantly sooner on top of the lightweight acceleration effects. It also improves shifting as it allows the engine to accel & decel faster therby improving/smoothing shift performance.

Remember, those dyno results were in 4th gear where the results are significantly LESS, so imagine in gears 1 & 2 where the engines torque output is multiplied many times over, the acceleration is very significant.

The pricing for the pulley is $499 with free international shipping.
Restocking fee for the pulley is 20% if it is used installed at then taken off again. Although, we've never actually ever had to use it because not a single customer has ever returned it once they have installed. Its such a well liked modification that most owners keep it on their car for life.

Hope that helps answer your questions,
AMS

Someone just bought these, can anyone guess who had the ***** to?

Weight is 1kg/2.2lbs anyone know what the stock weighs?

Ash current version gen2 of sprint booster works on both AMG and 320.The AMG version and non-AMG in gen2 sprint booster is 1 module now (was 2 different modules in gen1) its now just a flip of a switch.

Pulleys finally Installed !

Here is a bit of a walk through of the process. I hope this helps some guys if they are doing a DIY.

So I came home from work, and went right for my overtime.


next step is to take out the fan, is pretty easy just two clips on the top. And then un-clip the harness for the fan. It pulls right out.


next is the tension pulley, use a 17mm socket turn it counter clock wise and you can you rotate the tension pulley lose. then of course the belt would come out


I brought Evosport pulley kit long time ago, but I was never able to figure out how to install power steering pulley. Finally went to a local MB shop they lent me a puller tool and show me how to do it.


2 hours later ....... I f**K up
I pulled on the outer lip. I have to remove the pump from the engine.



But after a bit of snacking and TV. some magic happen.....



From here on everything went pretty smooth.
OEM weights a bit more than 3kg, AMS weights 1KG.

Good and bad we all heard about it. But for me I will give it a try.


Make sure the slot lines up with the new pulley and torqued it to 147FT-LB with 90 degrees more after torque is reached. Put a dial indicator and do a flatness check and run out check of the pulley.

and its time to nap ...... my favorite tool Nap-On



My list for this winter is to get carbon hood and save up for Okada project plasma direct.

Williams707

Can't wait to hear about the performance results you get. Also I'll check up on pricing for the Okada project plasma direct here in Japan, considering it's a Japanese Maker. Not sure what the markup price is outside Japan but at the same time the Yen Rate to USD sucks *****.

AMS Performance

Hello,

The stock pulley is 6.8 lbs, The AMS pulley is 2.2lbs

Correct, torque to 147tb lbs + 90 degress as per stock specs (comes out to a bit more than 200 ft lbs overall).

Pauljay

Nice write up Tery!

Is your power steering pump ok? Did you damage it getting the old pulley off?

Now that you've changed all your pulleys, please post up your 1st impressions.

tery

I totally F up the OEM one, thank God the Evosport one goes on smooth. I will do some dyno and time run using racelogic pbox once everything is done. Still trying to light weight the car a bit more. And new ignition system.

If anyone is interested let me know. Open to reasonable offers.

Thanks

This crank pulley will no longer be made, new company not interested in continuing the production of the crank pulley.

AMS bought out, new company offering 20% discount off all AMS inventory

BUT

The 20% discount is nullified by shipping charges when shipping was offered for free by AMS. Read the email from the new Company

Hello Jimmy,

Thanks for contacting us at GPT. The Prices on the overstock existing parts is still significantly cheaper even with shipping & handling charges. GPT has different policies than AMS and limited remaining inventory will be liquidated at current price as GPT has a strict zero discounts policy in order to promote price fairness. Once the current inventory is completely sold out these parts will never be produced again as we will begin to focus on newer exhaust components for the newest MB generations. The parts are already significantly cheaper than they were thus shipping cannot be included free. Thank you for understanding. Have a nice day.

Regards,
Johann

Congrats to those that jumped on the group buy!

That was very good timing!

So the shorty headers that made 2whp on my 500 are now listed on the new site as "up to 30HP", what a pile of rubbish.

That aside, AMS gave me a crank pulley FOC because of an unrelated issue and I have it on the car, no problems with it but that being said, it produced minimal measurable gains. A word to all those who have it - retorque it after 1,000km or so.

Williams707

What did you notice with the pulley? Let me hear your experience.

Kevwood

First off I will say that I had it installed at the MB dealer here and the service manager (a friend now) was very impressed with the quality and finish of the product. He also commented that the dampening qualities appeared to be sufficient for the M113 as they have a very natural balance to them off the assembly line. Personally, if he would have doubted any aspect of it I would have thrown it out, I also would never run something like this on my Chevys.

What I do 'think' I noticed was quicker rev up because it seems that the traction controll would engage quicker and with less effort. Something the 500 isn't lacking at all is bottom end torque but again, this may have helped.

On the dyno the final number (as per average) did not change (nor should it) but there did appear to be some mild gains in the bottom end. It's not nearly as drastic as when I use to change out to lightweight flywheels on my stock cars back home but I'm pretty sure there is a little something in there.

Now, if faced with having to pay $500USD plus shipping plus install plus retorque, would I do it? No, I would not for the simple fact that, like the AMS headers, the minuscule gains are far outweighed by the price. Then again, as the rule states, every little bit counts...

All up to budget I guess. You've got (IMO) the finest example of a 208 320 on this forum so you obviously are a good judge of products and expenditures. If there is anything else you'd like to know, I'm always around.

"Now, if faced with having to pay $500USD plus shipping plus install plus retorque, would I do it? No, I would not for the simple fact that, like the AMS headers, the minuscule gains are far outweighed by the price."

There you have it.

Williams707

Nice writeup very well said Puts to rest allot of theoretical questions people had and I agree, every little bit counts

And thanks for the plug about my ride being a fine example I really appreciate it.

Williams707

You left out "every little bit counts...All up to budget I guess."

Kevwood

My pleasure and you're welcome.

dlbehrns

Looks like you guys have the same front bumper.

Kevwood

The lower half at least

Williams707

What is That shiny thing and How did that Get there!!!

tery

I heard more is coming ! something from Japan but wait you are in Japan.

Williams707

Funny thing is, what's coming is coming from the States...lol
The Japanese Manufacture sells it $500 cheaper than in Japan. Go Figure

I can't believe how heavy the OE Crank Pulley is. Feels like 10lbs of dead weight.

I shot you an email.

Williams707

I plan on doing a review thread separate from this one. I'll copy out the other reviews from here and also include mine as well with my experience.

So for now I'll just say that "I'm Luv'n It" but probably wouldn't recommend this for anyone without major performance mods. It compliments everything else that I have.

Hope this helps.
