Ummm, Yeah, right- the steel band has always been there. This is the same pulley I posted pictures of several months ago- I thought you had a sharp eye?

NJPaprika230, That's the funniest thing I've seen all day!!!

Scylas

No dont let it go...

you guys are entreteining me, I been doing some work and your debate has been distracting me.... Keep it up guys!

Buellwinkle

OK, I can't resist! Boy that pulley is ugly. It's all full of holes!

See everyone, the group buy strategy worked, Kleemann dropped his price.

Is the new Kleemann pulley available for DIY installation or only through dealers?

Actually, its a mold for a pasta extruder! LOL! You get penne and manacotti at the same time:p

Buellwinkle

OK, then just maybe I misunderstood when you posted this as representation of your alloy pulley in the making. This looks like a steel cylinder pressed into the pulley and not a band.

Brandon @ Kleemann

Buell-

That picture is of an alloy pulley- taken at an angle in light conditions where the steel oil seal sleeve is picking up the body color of the pulley- Check it against the new pics (of the same pulley) you can even match the PN. Notice the seam on the hub plane- its a sleeve.

Our pulleys are made by one of ASP's biggest rivals (notice how I didnt say competitor) they have been making pulleys for as long as ASP. Both are excellent companies with all the right QC controls- the end products speak for them selves.

As for trying to match the mass- its a clever answer but Im not biting. Imagine what your flywheel/clutchdisk/pressure plate must tip the scales at- I assure you its well over 9lbs- try 30lbs. I dont think ASP wanted the cycle time on thier machine to drill and chamfer the holes.

revstriker

Not that I want to get in the middle of this (I don't even own a coupe), but I am trying to follow along here. Are you saying that these are both the same thing??

Buellwinkle

Brandon, that's the story ASP gave me, could they have made it lighter without the holes, absolutely. They purposely made a thick band around the back of the pulley, their reason was for harmonics.

So are your's made by AEM? I thought you said you had them made at your local vocational school

Revstriker, I just don't see it either but lighting can play tricks.

Brandon,
Can you use your pulley without changing the alternator pulley? It seems as that is the big job that takes the most time. Does it spin the alternator too fast, or is it just to cut down on the HP loss from it spinning faster?

Buellwinkle

You can use a 56" 6 rib belt without their altenator pulley. It's available at many auto supply store including Pep Boys where I got mine for under $20. From what I've seen it underdrives about 20%+ with the Kleemann crank pulley in place. IMHO, it's a risk either way, spin it 20% faster and the alternator bearings may last less, spin it 20% slower and your battery may suffer. It's like the air filter issue, every tuner has their opinion. Use your best judgement.

All these pictures of nicely machined metal are making me hot! Ooooooo Baby!

Duffer

Don't the holes make it lighter? And therefore, perform better without detracting from its strength?

Nice lookin' pulley, Brandon.

NJPaprika230

Gee, it sure is nice of Kleemann to include a larger alternator pulley to maintain the proper rotation speed and avoid JUST this problem...

Buellwinkle

I think you didn't understand me. The Kleemann alternator pulley runs the altenator about 42% less than stock, add the 20% the crank pulley gives you and Kleemann is underdriving the altenator about 22%. I don't believe in underdriving the altenator and that's one of my few feelings that I share with the engineers at MB. If you do mostly freeway driving then it may not be an issue, if you do a lot of local traffic it may not be good.

I would be agreeable to putting an alternator pulley in my car that compensated for the 20% larger crank pulley and ran the altenator at the proper speed but nobody I know makes that, if you find one, let me know!

can't u ask ASP to make a smaller alternator pulley then pack it with the alloy pulley and sell them as a kit?
wouldn't this make problem solved and no more worries???

Buellwinkle

First off, I don't think it's a problem as most tuners do not include this pulley. ASP makes money selling pulleys. If there's a pulley you want, ask Lee, they'll probably make it, specially if you can round up a few guys to agree to buy it. Tell them to make it a 1/2" larger to maintain the same ratio with the crank pulley if you want it to spin at the same speed. The Kleemann pulley is 1" larger. Borrow a factory pulley from someone that installed any C230 Coupe Kleemann pulley kit (SLK alt pulley is different) and send it to him as they'll need something to go by for pulley and hole diameter and offset. It's so small that I can't imagine it costing much.

The reason Kleemann uses a 1" larger pulley is to get the 1 or 2 extra hp out of underdriving the alternator. Unless you do all your driving at night with the stereo blasting and fogs on you won't have a problem with the alternator charging the system as modern alternators are highly efficient at lower rpm and can deliver full output as low as 2500rpm. In other words, use the larger pulley and don't worry about it.

We used to say the same thing in the Navy..

It isn't the size of the pulley that determines the cost. It is setup time and labor that are expensive, material is negligible comparitively for an alternator pulley.

Buellwinkle

That's why I suggested a few of you that want it ask for it as a group like I did for the group buy of the crank pulley. Decide on a size and go for it. It's actually a very simple pulley that looks like a solid hockey puck with a hole in it. It may very well be that another pulley he has already made for another car fits or is close enough so he just tweaks a parameter or two on his CNC machine (it's not like MB makes their own altenators). The width of the belt and ribs is a standard size.
