C36ickness

Hello everyone, I'm sure you've seen Omey from Abedin Motorsports talk about his new light weight crankshaft pulley. Well I have a 96 C36 137k rebuilt, and as all you M104 owners know basically there isn't much we can do to are engines improvement wise. So I saw the ad on Club202.com and decided to ask him some questions about it, and you can find the answers to those questions at his website at Abedinmotorsports.com. After the pulley was complete I thought why not if I'm going to get some extra power with some economy on the side for a great price why not get it. After a suspenseful wait I got the pulley, and the first day I would say it drove kind of weird, in that the you have to give time for the ECU to adapt. After breaking it in the 8th day your car feels like a C43. In part throttle the car gets going very quickly, responsiveness has improved greatly economy has also increased (I wouldn't say drastically yet still pushing the car) although after all the times I gunned it still got to 280 miles before filling up. But the one thing that I love about this pulley is how it's made my transmission shift so smoothly. I can definitely say it shifts basically like a luxury car. Let me tell you though the gains in the higher range after around 5300 RPM is not too great. Dyno testing will also be available shortly.

But you just wait currently he is working on Long Tube race headers for the M104 testing will probably done on my car still not sure yet. He is also expecting a bigger bore throttle body and many more things for your precious M104. Again I know I didn't talk about the pulley too much what you need to know about it is at his website, anymore questions you would all like to ask do not hesitate to. Pictures of my car will be posted tomorrow.

pulley,they are nice ,worth about 4h.p. in decrease of rotational mass,but hardly the second coming of Christ.The little 6 banger is all out of wind by 5500rpm and no light weight pulley is going to move that curve up.Why would it shift better?
I've heard a lot of things ascribed to light weight pulleys but never a comparison to a 43amg that is at least 7/10 of a second quicker 0-60 has a torque curve a mile wider that comes in 1000 rpm sooner.I think you either let you butt dyno get the better of you or maybe you should tell everyone your relationship to this new company

700 bucks for a 4hp CP does not a c43 make

Dr. C36

Educate yourself:

http://www.abedinmotorsports.com/M104dyno.htm

only 4hP huh? lol . It actually gives you more torque than C43 fyi, although HP slightly less), basically it avges out to C43 power with one simple & easy to do mod.

P.S. nobody asked you for your input

There are some of us on the W203 C55 forums that have the pulley for the 5.5 and speak pretty favorable of it:

"Just got back from the shop and The AMS pulley is installed and before and after same day dynos run. First things first stock pulley in my C55 was 6.6LBS and the AMS pulley was 2.8lbs The construction of this pulley is top notch to say the least. Peak HP didnt really change much but i picked up 15-10tqs though out the RPM range and about 10hp though out the RPM range. I cant give a full review on it yet as its not even drive 30miles. But shifts are smoother thats for sure. I also was getting 24.8mpg and thats the best this car has ever done. Anyway here is the dyno with before and after runs on the same chart. sorry for the large image kinda makes it abit easier to read"

Here is the entire thread with more info: https://mbworld.org/forums/showthrea...lley+crank+ams

oh come on. not this **** again. look dr. oh lord has a really good point - 4.3 v8 > 3.6 puny i6. much bigger area under the curve and torque kicks in almost immediately. and im not sure where youre getting your facts from but we need to see a c43 stock dyno compared to your dyno before you can continue making incredulous claims. 302 is alot to keep up with. period.

not to say that i dont believe that a lighter more well constructed cp CAN give you more hp, it definitely can. but to claim that slapping one of these puppies on is going to close a .7 liter/2 cyl gap between 2 motors is crazy!

C36ickness

hey let me tell you ohlord that you really should think about what your saying before you say it. My car stock! this is stock was basically the same on the dyno as a C43 mostly because it's rebuilt.

The other day I got in a rumble with a G37 S manual and let me tell you I was right next to him all the way to 80!!!

My car has 137k freakin miles on it and it's a 4 speed auto. Now with the pulley it's pulling even harder than before Omey on his car got up 21 ftlb. of torque in the mid range. So for 550-600 bucks for a improvement that great I think it's worth it. I can't stress enough how it's improved my car WE ARE TAKING 7lbs lighter than the stock pulley and I held them both I felt like I had a brick in one hand and a feather in the other. I also have a W210 E55 for my dad nothin much done to it just K&N he's old doesn't really care much for tuning to much. I've had a W209 CLK55, also a 203 C32 so I know what I'm talking about, and the funny thing is where the C32 has close to a hundred more hp it's basically as quick as mine if not mine is quicker. So really go and by a C36 if you want some pure unadulterated power. In half throttle going up to 3000RPM I get to 30mph, in 2nd 50, this is all half throttle. So try it on your car seriously not a bad upgrade. And thanks for the back Dr. I was wondering also if there is any Eisenmanns you know laying around I would kill for a race one. thanks

this is the STOCK dyno on my car 218hp and was about 209-211 torque

silence

the first poster should just have searched...

actually, wait- they should have just not even joined.

we all know about it, some of us even think it is a good product- we are all very fed up with these types of sensationalized 'hype' posts... particularly from someone when it's their first post AND when they use the exact same wording I've heard a million times before.

I vote teh BAN

ohlord

OP and the so called dr c36 educate myself?
I've built,raced,modded,every variation of mb engine or almost every since I started building engines in the late 1960's.Remove 7 pounds of rotational mass from the crankshaft,the rods,the valve train and then you are talking power real making.A 700 buck pulley is not going to do anything near what you claim and a C43 is going to pull you so hard your head will spin faster than your wallet did when they removed the money from it.

Dr. C36

So you want to ban someone b/c they are giving an honest impartial review of a new product they installed? If thats the case why in the world does this forum even exist haha.

The guy is just giving his impressions, if you don't like it then you don't have to reply to the thread, but creating lies or bad mouthing with no evidence or experience is hardly the mature way of having an intellectual discussion about modifications.

The guy is giving his impressions plain and simple, don't bash him or threaten him with a ban, thats just childish.

ohlord

say ban.It all makes for good readingForum review is peer reviewI applaud your defense of his rights to post,even if his statements are misguided.
His butt dyno will not win any races against a C43 coming on its torque converter a grand sooner,100 pounds lighter and Far better weight transfer.
6-7hundred dollars on a crank pulley has to be about the least productive dollar /power ratio mod I have heard of.

Z06EATER

funny how the c36 is called "puny" when its .1 secs slower than the ALMIGHTY c43

TVT_DESIGN

We've installed a couple of these on the M112 3.2L motors and have had nothing but negative results.

I think if they were more affordable it would be less of an issue not getting gains you could feel. It seems that the more money you spend the greater you want to feel the gain.

On the other hand it is a top quality product that is made very well. At 350.00 they would probably sell as well as the Sprint Booster.

Please elaborate.

ohlord

Funny how at 100 lbs. lighter and better weight transfer and an aluminum block and a fatter torque curve,a lighter valve train,lighter pistons,lighter valves, variable length intake tuning the C43 runs 5.7's 0-60. Unless there is some new math going on the C36 is in the mid 6's like 6.4 that's closer to a second than a tenth and is way more than a couple of car lengths even if you have the lightweight pulley installed.

C43AMG

Do you think its worth it for a carbonfiber driveshaft? ($1,100.00 )

Dr. C36

hehe, here come the lies.

Anthony you have not purchased a single pulley from us so I don't know how that is possibly true. In fact, I've only sold ONE pulley to an M112 owner and he was very happy with in on his C280 V6, the rest have been V8s or M104s. Most M112 guys don't really heavily mod their cars anyways (at least the NA guys). So again proven not to be true.

Second off the pulley has been independently dyno tested by many of the C55 & SLK55 guys to show the stated dyno gains (and sometimes slightly more). Further more the M112 & M104 are completely different engines with completely different crank pulleys, The M104 crank pulley gains are many times more than the M112 simply due to the nature of the pulley design and the power levels invovled. The gains on the M112 V6 will obviously be less than the V8 but thats to be expected. The M104 though is in a completely different league, the reduction in mass is drastic to say the least.

Finally, I have yet to get a single negative review from the 50+ pulleys I've sold in the last few months, everyone of them having been more than happy with the results as the numerous reviews have proven. Bad mouthing without facts, especially from you is uncalled for.

The C36 & C43 have been tested by many magazines, the C36 on avg had 0-60 of 5.8, the C43 roughly 5.7, its been documented many times, no point in hashing this debate out all over again. C43 is quicker, slightly stock vs. stock no doubt, but not by a TON like most people make it out to be. Stock mb claims are always bogus, and they have been from day one, magazine test results & real world testing are what really matter.

First of all thank you for all the input Dr. C36 I appreciate it, I'm seeing to do much more business with you in the near future, and hey the reason I did that first post is to help out Omey and his business. As you all know spreading the word is the best way to help a business. I know this pulley has gone around every MB forum but hey why not one more satisfied costumer. I mean if you all know what it's about you don't have to read it I'm just giving some more input on someone whos maybe joined recently or they would like some more feedback from a person who has the same car or somethin I don't know but heck it's just a forum there is no reason to get all about somethin like this. Again no disrespect to anyone but for a 19 year old kid to spend as much money on it as I have from the little crappy job I have to rebuilt the damn car you know some props would help. Again my opinion on the pulley is mine and nobody can take that away from me thats what I thought forums were all about to express your opinion and get other peoples feedback from it. If you don't like the pulley 1: try it and 2: ask other people first about there impressions on the subject if that person thought the pulley was crap and had horrible luck with it then hey I'm sorry for them. But I have yet to see a disappointed costumer.

Z06EATER

i'm talking stock for stock buddy, not mods, ok. we compare stock, any modded car vs any modded care is a total dif. story. stock vs stock the c43 and c36 are similar in 0-60 mile times. why u gotta be an a-hole about it?

PJmak

c43 is faster but itll never have what the c36 has, no other amg will ever have that and if you ask me, that makes up for its performance when compared to other amgs


if you dont know what im talking about then gtfo this forum

ohlord

day that nearly 30h.p.plus more torque coming in at 33% lower in the power band,100lbs lighter engine and car and still pulling power at higher rpm is only worth a tenth of a second someone is smoking something
Edmunds.com,drag times all the reviews and tests of stock models we have done at the track will put the c36 way off a 1/10,don't know where your figures are from but real world physics don't jibe with your numbers.Lined up stock for stock the c43 leaves harder and arrives quicker.A lot quicker.Not being a a hole just facts and stock for stock line them up and the c43 will leave you at the curb.

To the new op,glad to have you in the mb family,all that matters to you are your own impressions,just make sure if you are the betting type that you don't take on a c43 heads up,that 1/10 of a second is a real long time when you are watching it cross the lights several car lengths in front of you.

Dyno numbers are only a comparative used for tuning...
They can even lie, especially with a inertia type dyno.
Too many variables which don't translate to when the rubber hits the road.

What are the "real world" before and after 1/4 ET's for the lightweight pulley ?

Based on the dyno numbers posted the modded C36 should run 0-60 in the low fives and mid 13's and 100+ in the 1/4....can anyone confirm ????

RBYCC

I have never seen such a raggedy dyno chart in my life....

You did a base line run seven years ago and achieved max hp @ 6300+ rpm ????

What gear did they start in and why is it reading at a low 2500+ rpm...???
Are the spikes gear shifts ????

With a auto trans you usually run in third gear from 70 - 105MPH which will allow you to reach peak engine RPM.
Any shifting while the reading is being calculated will give a false reading.

HP = Torque @ 5252 RPM which is an undisputable calculation.
HP in a dyno is not a direct reading but a mathematical calculation based on torque.

How many runs, what is the ambient, what type of fans, and is it an inertia or load dyno ???

Dr. C36

Ahmen Brother!

Saijin_Naib

Dr.C36, do you know if this pulley would work on the m104 engine (same 2.8L used to make the C36 engine ) in my 300ce?

Dr. C36

You are the worst dyno chart reader in history, you KEEP misreading the charts over and over again. The high curve is HP (left X-axis) and the Torque is the right X-axis (lower curve). The dyno operator just forgot to put the same scale on both axis which is why it looks the way it does. If you put same scale they cross at 5250 of course (duh).

no gear spikes obviously, if there were you'd see these massive spikes troughs which there are none. Its obviously a single gear run b/c theres no gear shifts. Its easy to make the C36 start at 2500 if you know how to properly dyno a C36 (disconnect traction control) and ease into it at 2500 instead of sharp pedal drop.

Its obviously a Dyno Dynamics dyno b/c of the familiar yellow checkered background (DD is the only one that looks like this).

Hey C36 sickness can you get the dyno operator to get you a chart with the axis redone so its much easier to read (250 max on both axis). that will help limit the confusion.
