Just out of curiosity...
who's interested in this puppy?


https://www.northamericanmotoring.co...itanium+pulley

it's pricey, it's titanium, and it's "uber"
im just trying to factor in the $597.75...
will the titanium really make that much of a difference in this?
in other words, the speed of SC pulley... so if this thing can spin "faster" what difference does it make if my crankshaft isnt spinning any faster? considering that they are directly related wouldnt it amount to no difference than any other 15% pulley? maybe 1, 2 horses at best, right?
and if it is spinning faster, doesnt this equate to even greater wear on the SC than your typical 15% pulley?

Any other opinions out there?
PaloUber... any dyno charts to compare with? id like to know if it's painted or is the black part of the metal process. and maybe a little more info on the self aligning aspect. does it self align during installation?

Thanks in advance

 

Ouch, my anus hurts just thinking about how bad they are reaming people with this one.

Its probably worse than the stripes!!


There is no way to get more power out of a 15% by making it lighter. Its still spinning just as fast as every other 15% reduction pulley, so theres no way for it to make more power. The pulley is already so light, reducing the weight even more would do nada to it. There rotating mass is already so light, there no difference between an aluminum or even steel and a titanium pulley.

If they claim more horse than the next pulley, then its not a 15% reduction. Plain and simple.


But then again, is $600 bucks worth it to you for the name? Ive never heard of these guys before, so I really have no idea what name your paying for.

 

well, from what i've "heard" palo uber's pretty well known in europe for their cosmetic parts but performance wise i only see the exhaust on their site...

but as far as the rotational speed goes, it seems we see eye to eye on this... 15% reduction is 15% reduction, weight should have nothing to do with this since it's on a "group" of pulleys dictated by crank shaft...

i rate this mod right up there w/ that CF lip thingamajigger on the spoiler for $345

 

The titanium pulley is 0.5oz lighter than the Aluminum one. So 5oz versus 5.5oz. I dunno they also claim that the titanium forms better than the aluminum and steel ones so the shape is perfectly round and smooth in every part of it. They claim no belt hop at all either. Is belt hop common for all you "pulleyed" owners?

I'd be interested to see what Mini-madness has to say on this product as they are partners with these guys. I DID notice that they both sell the Aluminum pulley which looks the same as the Titanium one (6 bolts) and it sells for $150 at madness, and $198 at Uber. Hmmmm I think I'll order from Madness if I decide to go 6 bolt. =)

I would like to see a NAM member pick one up and dyno it though. I'd say let's not flame it on to the likes of Alteeza lights just yet.

 

i dont know of any pulleyed cars that have had belt hop. ive heard of a tensioner blasting off but that was due to neglect...

and you're right pyratio, why would you wanna pay $198 for the same pulley at $150?

as to the dyno, im wondering if PaloUber did any dynos of their own...

 

At the 15% size, I have never heard of "belt-hop", or any belt issues whatsoever.

PaloUber is seemingly just trying to justify the outrageous cost of this pulley, with what some might call marketing BS, or scare-tactics. Yes, titanium is the real deal, strong and lightweight; a metal for racing vehicles. BUT, that the difference in weight versus any other 15% pulley is negligable, at best.

I see this titanium pulley as a bling item that some owners could use to visually one-up their buddies at the local cruise some Friday night.

This pulley cannot offer any performance gains over the myriad of other well-established 15% pulleys out there; it is just another 15% pulley. Size is what matters for making power.

So, since it is about the bling, you have to ask yourself if it is worth that kind of money, when it is hidden down so low in your engine bay anyway. Who's going to see it and appreciate it? If you need pulley bling, get the powdercoated red pulley from CravenSpeed, which you'd at least be able to see!




If you really want bragging rights, buy the polished DFIC. Something everyone can see!

 

Hey! Cut that titanium with a laser and I'll pay $1000!

Seriously, the number of actually high-performance parts you can buy with the extra $400 from buying any other pulley is amazing.

The only way it would even be close to worthwhile is if the price included installation.

Now, who would like to buy my mink-stuffed seat cushions or my beaded seat covers made with real burled walnut?

 

This might match your handbag but for the most part it just ridicules your intelligence while abetting the life style of the rich and famous.
Marketing personality cult fiction

Helix has 6 screw SS pulleys that are hub universal for all pulley sizes 15,17or19% $120.00.
This means that once you have a Helix pulley and the Hub you can change your pulley ratio for like $80.00.

 

I'd like to find out how much the moving parts of the supercharger weigh, and how that weight is distributed relative to the centerline of the supercharger shaft. My gut instinct is that there's enough mass elsewhere in the shaft and rotors that the weight of the pulley is going to have a negligible effect on how much power is required to accelerate the supercharger. This is especially true because all of the weight of the pulley is within an inch of so of the shaft centerline.

 

I'm personally waiting for the Unobtainium pulley. I here it uses super rare metals that actually adds power to the engine instead of taking it away through a parasite drag. It also uses 360 bolts to hold it to the hub so you never have to worry about it coming loose.

 

Palo Uber's stuff is crap, and so goes his art.

From the vendor announcement...
"Titanium is lighter than aircraft aluminum and over 112 times stronger. Titanium is a fraction of the weight of stainless steel and again over 130 times stronger."

For those that would like a comparison,
a 3" round piece of 7075 aluminum 1" thick weighs .7152lbs
that same size chunk of titanium weighs 1.1526lbs and the
stainless chunk weighs 2.0648lbs

I don't know where they get their info, but it seems to me that it is just plain wrong.

 

Sorry, but I'm not going to pay Ferrari pricing for a cooper part. I don't see the justification of paying so much money that they claim can add 1-2 more HP than the standard 15%.

 

 

I swear I just saw a McDonalds's add flash on my screen ! Now I'm hungry.

 

This sounds like a mod that some GP owners might be interested in.

 

The point is $597.75 compared to $120.00 for what?
Yes several people on here have had some problems when it came time to tighten down the screws and used ft lbs. rather than inch lbs.
Some didn't torque them down evenly or use thread lock and they came loose.
By the way my 1970 Renault had three lug nuts per wheel. Why don't you apply that logic and save some weight on your MINI just remove 2 per wheel and let us know how that works out.

 

Have you ever purchased anything from them?

Until, you have please do not make any comments.

 

I'm just waiting for the titanium spoiler stretcher....

 

It may be wrong, or they may just be unclear with their conditions.

Consider these two separate statements:
1) A titanium part will be lighter than an aluminum part *of the same strength*.
2) A titanium part will be 112 times stronger than an aluminum part *of the same weight*.

So while both parts of the manufacturer's claim may be true, it's not possible for them both to be true at the same time, for a single part.

As an example, my motorcycle has various fasteners of mild steel, stainless steel, Ergal (a type of aluminum), and titanium. The *only* time you want titanium is for fasteners that must be both super-strong *and* somewhat lightweight. If it only has to be light, aluminum is a much better choice, and if it only has to be strong, mild or stainless steel is a better choice.

 

***WARNING...PHYSICS CONTENT***

Right and wrong. The velocity, or really the angular velocity (omega), is not faster or slower than any other pulley on the market. A lead pulley will spin at the same velocity as the Titanium one. It's the delta omega, or change in velocity, that lightweight pulley's help. As you said, the lighter the pulley, the faster it will spin up or down.

PARTSMAN is correct. The density of Aluminum is 2.7 g/cm^3 while the density of Titanium is about 4.5 g/cm^3. This makes Titanium abut 1 2/3 times heavier than Aluminum. Unless they are making it thinner (since Titanium is stronger), the exact same pulley will weight more in Titanium.

 

I had asked the question about SC pulley weight a few years ago, maybe even when NAM was called MCO...

Randy Webb, our pulley guru with an engineering background bascially said that while the loss of weight is noteworthy on free-spinning masses (think wheels, tires, rotors...), on something belt-driven, the effect is much, much less...

 

One more thing to think about... Aluminum, steel and Titanium all have different coefficients of thermal expansion. This means they expand and contract at different rates. What happens when an Aluminum pulley on a steel shaft gets very hot? The Aluminum expands more rapidly and possibly works itself loose. That's not something I want to worry about.

 

Randy is also quick to point out that stainless steel pullies expand at the same rate as the supercharger shaft, (being that they're both made out of steel), versus the expansion properties of aluminum, or in this case, titanium.

I don't know if that actually matters or not, in the grand scheme of things, but it sounds like it makes sense.

 

It makes a lot of sense on that alone. Throw-in the huge price delta, it seems like one of the most obvious no-brainers out there.
