For those of you that cross post...

I was wondering if anyone has purchased the pulley I am referring to? If so, what were the results?

thanks

Jordan

 

Just purchased it and will have it in a few days. I'll post results and install pics...

 

Where in the valley are you? I'd like to see the pulley if possible. Thanks.

In the Northridge area. I will probably try and install it this weekend when I get back from my business trip in the Bay area...

 

 

 

Hey Jimmy,

What is the pully for? And is it worth it?

 

Hey Raff, check this thread out; I know it's long but worth the read:

Thanks Jimmy.

Did you install it yet? Do you like it?

I asked him if it's going to be O.K. with the powerchip I have? Should be; just double checking.

 

Nope, I'm up in the bay area and won't be able to install it until I get back. Hopefully I'll have some time this weekend. I don't have a breaker bar though so I might have to go out to my friend's shop and ask for a hand or a tool, lol. Anyway, it will work fine with your chip because it replaces your OE crank shaft with his newer lightweight pulley with the same diameter. Let me know if you decide to go with it and we can have them installed together...

An interesting take on the pulley

 

Steve Dinan wrote an article about LW crank pulleys a while back: http://www.atiperformanceproducts.co...mper_dinan.htm

Here's another article about light weight crank pulleys: http://www.modtest.com/host/riemer/TorsionalDampner.htm

And another: http://www.teamscr.com/pulleys.html

 

Jeff this is true but all if not most "other" lightweight pulleys don't have a harmonic damper/balancer, it is removed on their lightweight pulleys. Read the link above about Omey's pulley and even talk to him about it; it has a newer/better harmonic damper/balancer in it and from his testing, out performs the one from the factory, which has had numerous problems in the past. I am looking at this as not only to gain a few horses but also as an safer improvement on the crank shaft pulley. Just my $0.02...

Hi Jimmy,

I was just giving the people some food for thought.

Based on what I've read and the advice of my favorite shop, I personally don't think it's worth messing with the balance of the engine for a few hp. IMO, the risks outweigh the reward.

Risks:

-engine longevity
-increased vibration ?
-severe engine damage

Rewards: (arguably)

- a couple hp (though I'd like to see some 3rd party test results)
- mpg increase (again some 3rd party test results rather than omeys 15 mile run)


Nothing against Omey, I just don't think the LW pulley is worth it. However, if someone can show me significant gains (>5 hp) and prove that it doesn't harm engine longevity (50k+ miles of testing) then I might do it. At this point, no one (to my knowledge) has done this level of testing. If you're looking for more hp, add a blower, headers, or port and polish.

 

I know what you mean and I'm not arguing but from doing some research for myself and like I mentioned previously, the reason everyone else's LW pulleys have failed and/or caused problems is due to the removal of the harmonic balancer/damper. I have read a lot of the negative responses like the ones you posted but they don't outweigh the positive; especially when our cars come from the factory with POS pulleys. After reading all of the crank shaft pulley nightmares that people had with their OEM pulleys, I figure this one can't hurt, lol.

I am very hesitant before getting into anything that could potentially affect the reliability of my car like s/c's, etc. but I guess this can't be worse than the faulty pulleys already on our cars. Realistically, if this things turns out to be bad, don't worry I will make a pretty big deal about it, lol.

Now, let's see if this thing can and will do what it claims. I will be the first to post from personal experience but only after extensive driving.

Take care brotha and let's see what happens...

 

Hi Jimmy,

You're right, from 1998-2000 the OEM harmonic balancer was rubbish, hence the recall. Mercedes since revised the design and I haven't heard of any problems with the newer balancer, but I could be wrong on this.

My concern about Omey's pulley stems from the fact that changing the mass of pulley will change the natural frequency of the crankshaft and change the frequencies that need to be damped. Omey hasn't exactly shown any equations regarding the damping characteristics of the harmonic balancer or the natural frequency of the crankshaft; he has shown us F=ma and I=mr². Now, this is not to say that it won't work. I'm just saying that it seems uncertain how much vibration engineering when into the design and that is what concerns me.

Anyway, enough of this. We're all old enough to make our own decisions. I think we're really here to see what kind of results and impressions you get from the pulley. Keep us posted! Oh, and would you put it on already!

 

I am up in the Bay area on business and will put it on when I get home this weekend; having the time that is, lol. My 14 month old daughter is making me nuts, lol. I will post results of a positive or negative nature once I've driven the beast a few miles...Thanks for the info Jeff and talk to you guys in a few.

 

I am trying forever to PM Omey for the pulley but for some reason it is no letting me do so, has anyone installed it in a w210 E55 , and how may I be able to reach him to order one?

 

You can reach him here http://www.abedinmotorsports.com/home.htm

 

thank you kindly

 

Hello Max, I received your email and responded. Sorry been out of town for the holiday.

 

The steve dinan comments aka notoriously dubbed the "Dinan Papers" caused so much controversy among the automotive community and created so much bad publicity for Dinan that they eventually had to take all their comments back and retract their statement. It was more of a plea to badmouth competitors than anything else. Also that only applies to non-harmonic dampened pulleys anways, doesn't apply to my design.

 

Thanks for chiming in Omey!

 

Hello Jimmy,
Any word on your pulley instalation?

 

Sorry, I've been away on business and just picked up the pulley bolt yesterday. If I'm not leaving again tomorrow I'll try and have it installed this weekend. Man life is just too busy right now, lol...
