Do Lightweight Pulleys FREE Power? With Poll

I dont think you can have it both ways.

Where is @tennisfreak when you need him?

I still don't believe it is a damper in the way you are saying. I still believe your ideas come from out of use tech from old massive engines.

I don't need to be positive. If you are so sure of your position you should easily be able to find tons of cars with lightweight pulleys that actually damaged an otherwise stock small displacement normally aspirated engine.

I am positive there is absolutely tons of user data out there that says they are not a problem. I am positive there are literally countless number of people running lightweight pulleys all over the world with zero problems. I don't need to know absolutely everything on something when such a gigantic trove of information says I am correct.

But if you are correct you have to have seen proof somewhere. Actual tangible proof of a lightweight pulley damaging an otherwise stock normally aspirated small displacement engine. You just have to have tons of actual proof somewhere to be so sure you are correct.

I'd just like to see it.

Whoosh. Context knowledge and situational awareness is importanter.

Belief isn't necessary. It doesn't change reality or fact.

The only evidence suggests it is a damper pulley, based on design. Whether it is effective is factual, but no one has actually come forth with any data one way or another so we can only speculate.

Similarly, though much anecdotal evidence might be gathered suggesting that a damper pulley may not be necessary to keep the engine lasting longer than other pieces, there is no fact one way or another. And as much as any other engine may or may not have problems is quite irrelevant to this discussion.

Touting belief means nothing whatsoever - and certainly doesn't make it factual. Bringing forth anecdotal evidence may suggest that a light-weight crank pulley won't be the first failure point, but it does nothing to say the stock pulley isn't a damper pulley, nor that it's ineffective entirely. None of us arguing have that data (at least, that has been shared.)

Whee.

Evidence suggests arguing on the internet is futile, but I persist... I guess I believe I may some day make a difference. I'll wager today is not that day.

I stated as factually as I possibly could.

The heavy round disk shaped thing bolted to the front of MY FA20 engine is 100% a torsional dampener.
Ask ANY mechanical engineer what they would describe it as and I dont know of one that would say anything different.

Did I say that the engine needed a torsional dampener OR that the engine would be damaged by substitution of it with something else?

No.

Eight years of trouble free daily driving and track sessions on a set of NST pulleys.

Thank you for posting your real world feedback.

You DO see that there is a fan and fan clutch attached to that pulley right?
AND if I am not mistaken, isn't that a WATER PUMP that that pulley is connected to and NOT the end of a crank?

Apples /= Orangutans.

COMPLETELY violates the comparisons between torsional dampeners & harmonics balancers AND makes the difference moot.

AND WHAT is THAT to the left of that picture???
Isnt that the STOCK pulley on the end of that crank?



It is about as relevant to the conversation as this:

To be fair, the thread itself isn't just about crank pulleys. I'm sure these are well made pulleys, and you can lose a pound swapping the accessory pulleys and leaving the stock crank pulley. Plus more bling.

Actually, that's the AC belt tensioner. I can see his sooper-dooper crank pulley down in there.

I give up. Let the kids waste money on their bling. You, I, and our brethren will always find this sort of misinformation frustrating to no end.

It is about as relevant to the conversation as this:

Three NonStopTuning pulleys in blue. Alternator, Water Pump, Crankshaft. The other pulley to the side is a tensioner pulley.

According to the customer these pulleys have been on the car for over 8 years and counting, with no issues. For this one AE86 owner posting here, there have been hundreds of others with NST pulleys (and other products) rolling around the USA and other parts of the world for over a decade now.

Real world experience speaks volumes louder than forum arguments, trolling, and bunny memes.

Thanks again to the OP, best of luck with all your projects.

I am sorry but the multiple engineers expressing their thoughts based upon years or training and experience here trumps your alleged "real world experience" by a significant margin. Your accusations of them trolling is frankly very bad taste for a vendor. Guess you really only want to sell to those that don't know better anyway.


As a manager working in 4 manufacturing plants providing OEM parts to all the car companies I can 100% guarantee that if they could get away with the cheaper turned pullies they would be using them.

[chaoskaze]

😂 obviously just lightweight alone don't do shit.

Toda pulley with revised alternator ratio. This one actually give u more power.... But your car might be draining battery all the time. Because racecar!👌

[OkieSnuffBox]

Wait, so if we are using other platforms as justification for the FA20.........can I point that NA/NB Miata engines eat oil pumps at high revs without a quality damper?

No one uses a piece of turned aluminum for 0.05% faster Rev increase. The big boys are using blueprinted pumps and nice dampers to keep things together.


So this is a legitimate argument against them in this context, right?
