crank pulley upgrade?

Why don't you all have a FluidAmpr?



it would upgrade the truck in like 5 different ways and is only ~$300...

 

What 5 different ways?

 

Do you have one? And what has it done for you?

 

Know nothing about this brand but it’s the same concept as a lightweight flywheel. Increased Throttle response is most noticeable. Like any reduction in rotational weight, you don’t need the same effort to get it spinning.
Good for street applications but not sure I’d use one for wheeling since heavier mass would be better.
Iirc, our trucks are also more sensitive to having a dampener in the pulley than other vehicles which not all brands incorporate but this one’s name tends to imply it has some variation of one.

 

Why not me? I've gotten along my whole life without one and the cost ($400PLUS) gnaws away at my innards like a bad case of the bot worm. For me, these 4.0's are basic, raw, tractor motors. Like the one what used to be in my XJ. They're bred to be largely left alone. Putting a fancy dancer balancer on it is like putting nipple rings on a librarian. If'n it were 50 or 100 greenbacks, I might bite. But I can think of many other mods I could do for nearly half a thousand bucks.

 

Made in Buffalo, NY!

 

How often does the oem pulley fails? Although it does look cool.
$300, wait..what? .nah, that's uncool.

 

I'm not trying to derail the thread, but I've known a few librarians... and while I'm not saying I'm an expert, you and I might have different ideas of what they're like off the clock.

 

Actually it has nothing to do with weight. The V8 blower guys use them and for good reason. Not only are they SFI certified - which is required at many tracks - but they are vibrationally tuned to a higher rpm than the OEM balancer for those engines running higher rpm. OEM balancers are tuned (via the elastomer they use) to dampen crank harmonics in the OEM rpm range. Once you go beyond that range in racing you really should get a balancer that protects in that higher range. This is particularly important to the newer engines that use crank mounted oil pumps. The Ford modular engines and the later LS engines have problems shattering oil pump gears due to harmonics. Lots of info, but that's the background.

 

Because so many Tacomas need to worry about being track-legal. If I'm running a blown LS on a 1/4 mile car, sure, but for 99.9999994383984% of Tacoma owners? This is nothing more than a VERY expensive solution to a non-existant problem.

 

Yes, that was my point.

 

v6's are car engines
tractor motors are inline

$300-400 on step bars that belong in a dumpster
Now that's cool

no not really it's actually the opposite
Fluidampr improves dampening

also, speaking of a lightweight flywheel; those are often single mass. As opposed to dual mass.
the Tacoma came with a single mass

No because they won't engineer one for the 4.0L unless they get 100 people interested to justify production costs

I had one on my last vehicle and enjoyed it. It
-allowed me to cruise/coast down to a lower RPM when decelerating having to downshift or clutch in. Slowing to a red light in a higher gear was made easier because the vehicle no longer shook
-the vehicle was easier to drive and control because power delivery in the RPM range became smoother and more consistent
-there seemed to be a little more power
-shifting was made easier and more predictable
-although it was a street car, I'm sure the benefits of smoother running and lower rev-ability is useful for off road applications
-it countered the single mass flywheel I had on that car that did not dampen as much as a dual mass. Even though the Fluidampr was on the front of the engine/crank and not the rear, it was still part of the rotating crank assembly therefore offered improved damping
which allowed me to retain that single mass flywheel that was otherwise good in regards to light weight, reliability, and so on
-it let me chill at low RPM. stand-still traffic on the highway? No problem. Lurching forward was lessened, it gave me more fine tune of the gas pedal, and could swing through any portion of the revband rather than jumping around begging to be just used as an on/off switch (pedal) which although is great on a cold sunday morning empty street, does not work in traffic that constantly changes speed

I would rather have one that not have one

 

Waste of money.

 

Yea, but we're not talking about race cars. The question was asked about how it could effect our tacomas.

So if you're not changing the size of the pulley then there's nothing else other than the weight that can make an impact.

 

you cannot change the size of a pulley or it will alter timing

Fluidampr does not get its improvements from additional weight
It gets them from being designed with a moving silicone fluid ring inside, which is why Fluidampr is called Fluidampr (fluid damper)

the factory damper does not have silicone
It is cheap solid rubber

saying the only way a pulley can improve is by making it heavier is like saying the way to make a 2020 laptop better than a 1995 laptop is by casting it out of lead

 

Go for it,and let us know how improved your Tacoma is.

 

TT - just my two cents. In the right application they are great. I don't think our engine is the right application for the reasons posted above. On another note, do you know if they are even made for our 4.0? If so, and you want to give it a try, it certainly won't hurt. But I really don't think it will help. Let us know what you decide.

 

I think you misunderstood what I was saying. Our trucks need the damper on a crank pulley.

A lighter weight flywheel/pulley, that reduces crank and rotating mass won't benefit off road/rock crawling. Same with towing. The heavier mass is beneficial to keep r

underdriven pulley kits have been around forever. What do you mean you cant change pulley sizes?

"There are two ways to reduce the power the engine is using to turn the accessories. These methods would be to either increase the diameter of the accessory pulley or decrease the diameter of the crankshaft pulley."

I dont even know why I'm going back and forth on this. I'm with everyone else and have no interest in this for our trucks.

 

Wrong section man. Gotta put this in the performance section as to not ruffle the instalanders. They only need LEDs, rtts, and cmc for dem tars.

 

But truth in there.
