FluidAmpr group buy

Because you're comparing a luxury vehicle's engine to a truck.... And VAG group engines are already known to have a ton of things to them that are causing more issues down the road than good.. And yes I have owned VAG group vehicles and worked on them. Sorry, but I just don't see logical reasons why this is worth people's time and money in this particular instance....

 

I don't have a second gen, but I had a Fluidampr harmonic balancer on my 2005 Mazda6 3.0l and it was fantastic to drive with. More power throughout the RPM range and idle was much smoother too. The engine felt like it was more in sync with itself and like it would run forever.

That said, it was 10% underdriven on that platform and after installing it I went thru 4 a/c compressors in ~25k miles before I traded the car in. Not sure if the failures were related to it being underdriven, but hopefully it's not underdriven for this application. If they make it in the factory diameter, I would absolutely get one if I had a 4.0l. I love upgraded crank pulleys, but I would not get one again if underdriven.

 

same
but
That damper is one thing that on those cars probably won’t fail, and yields improvement

exactly
seems more of a diameter factor

 

More power? Now that’s a dubious claim

 

10% smaller diameter will yield a small amount of usable power because there's less leverage against the belt driven accessories

 

Sounds like placebo effect. You aren’t going to feel 2hp

 

I'm inclined to agree

 

I always like these statements. Not here to argue, but only make a point about "feeling". If you can feel a flea on your leg or arm hair, a mosquito the same, then I bet someone can feel an increase of 2 hp on a N/A 200 whp engine. At 1000whp, that would be harder to notice.

 

You cannot feel a 2hp increase in a 200hp engine. You analogy is flawed because you don’t use your fine touch sense to feel horsepower, you use pressure and your inner ear.


But people make a LOT of money selling 2hp improvements, so…

 

FluidAmpr frees up torque and HP. A small amount. Maybe 10.
There are tests showing it gain 10 tq and hp.

Which on this truck I'd take that. Because there's not much else you can do.

Not hard to find people happy with them.

Nobody said it adds 200hp.
And, it's cheap when you compare to the dumb shit people do to their trucks, such as these wheels and step bars

 

But sensitivity is personal. A body and experiences are individual. So someone certainly can, while another may certainly not. Acceleration is not felt by the ear, but the G force. Personal experience is the factor that creates subjectivity. Therefore it is entirely possible for someone to feel such a thing. Harmonics as well. They might change, and could totally be felt at the onset of part change, as then different. Which doesn't have anything to do with power change, but just that a different frequency could be noticed when referenced to that change. At least until then again used to it.

 

Bruh.
It yields like +10hp/tq. He got the feel of his truck driving it every day.
If it felt more powerful to him, that's because it was more powerful.

You know what else people say yields a small worth it improvement that I want, if not now, at some point?
better VVTi solenoids like the Red Bullet group buy.

Those are the options short of a supercharger which is what, $5k+?
That give you a little bit more power out of a 1GR-FE, more fuel consumption, and higher octane fuel needed (more expensive)
which, if ever going that route down the road
some if not all of these mods, can get transferred over/re-used for that, to help maximize that more, if not be required
like cam gears (that I already have)

the cam gears added some power
they're just cheaper
would I go back to not running them? Probably not.
Do you "have" to have cam gears? No. I'm sure it's trucks going by on the road without em.
Don't have to have milk in cereal either

 

I agree with you. Especially noticeable on engines that have tuning imbalance or internal imbalance. Inline engines, such as the inline 6, can benefit a good deal from these.

 

My comment was to the post above yours.

 

I get it. Inline 4's are unbalanced as shit. Especially if you take a dual mass flywheel off it, and put a single mass.
Why do so many people do that?
Dual masses mess with feel, are expensive, add weight, and break apart. Audi put them on as "luxury". Cheaper VW, single mass
interchangeable parts
so many people, when doing a clutch job, switch to single mass (including myself)
dual mass dampens more, so you lose damping, and get some chatter. That and a bit more power freed up.

Power isn't always about having the engine make more
but rather freeing up what it already makes, preferably in a safe way without drawback

Or, in our case if you have manual, the Tacoma is single mass. But, different in that it's still a big heavy single mass. Still not as much as a dual mass.

Is a V6 more balanced than a 4cyl? Sure. But I wouldn't say it's perfectly balanced. It's definitely not as balanced as a V8, V10, V12, flat boxer 4/6, etc.
and firing order will have a say, and there's still combustion pulses no matter what

If V6's were perfectly balanced, Mercedes would not be putting one or two counterbalance shafts inside of their V6, like M272 I believe



and, 1GR-FE angle is 60deg
probably not as balanced as other V engines that use 90deg

another thing I forget
on the vehicle I had it on, shifting was better
1. with RPM becoming more precise
2. any rev hang/drop improved

I see they have models for V6(s) including VW/Audi 3.0, 2.7TT, 2.8
and VR6 I believe VW 2.8L and 3.2L such as in the MKIV R32
I think if there was no benefit on a V6 type engine, they would not have made one

 

Oh no. They definitely aren't. They are only balanced good enough from the factory, to get them out of the door. Simple economics for a company, based on the specifications needed for the nature of the engine. Some engine leave a lot of room for improvement. I have had both of my engine balance. One has an OEM crank. The current one in the truck uses the ATI damper, to help with harmonics still.

Back to the "feeling" topic. There was a similar debate that raged on for quite some time, about installing the NST lightweight pulley. Roughly quoted,"You can't feel the improvement from light engine pulleys," was one camp. The other camp said that they could. Once datalogs of before and after started being posted up, showing noticeably quicker revs, which equated to quicker acceleration, then it was proven that those that said they could feel the difference were actually feeling the difference.

 

2000's Toyota has manual belt adjustment pieces that look like something a caveman came up with; that probably can be adjusted by a caveman equipped with a rock (in some aspects, that can be a good thing)
and my 08, the features are: a seatbelt
so when it comes to a probably, sub $50 damper that's kind of a rubber puck
either they chose the cheapest thing they could, or don't know how to make anything more, or both

I bet lighter pulleys do yield more power, but that opposite way of doing things I'm not sure I'd do; gaining power at the cost of worsening damping through, still a cheap primitive part (solid metal) albeit lighter
like cutting my arm off to jump higher

 

I feel like my point was lost.

 

There's always someone like you who comments on these types of posts. I don't really care what your opinion is, my findings weren't a claim. I had my car dynoed before and after the pulley was installed. While peak horsepower only showed a gain of around +5whp, the midrange torque had increased fairly substantially for the platform (IIRC something like +13ft/lbs), likely due to being underdriven because the pulley was substantially heavier than stock. IDR the exact numbers, it was like 15 years ago and those graphs are long gone on old webhosting servers. Everyone else who installed one reported the same findings as well. You can't compare parts across different platforms anyway so that part of the argument is null, I was just trying to make the point that the upgrade was worth doing and the vehicle felt better and much smoother as a whole after installing. Tacoma's aren't known for reliability issues, but adding a harmonic balancer is a great upgrade for any vehicle that they are available for. They really smooth out the idle and acceleration, and anything that reduces NVH without hindering performance is a win in my book. I hope they make this for the 4.0l so you guys can experience it, surprised they don't already tbh with how popular the platform is.

This guy gets it. My tC2 has an Agency Power LWCP on it and I noticed similar gains, if not more, than the Fluidampr on my 6. The 2AR in my tC has balanced internals so it did not need a harmonic balancer, but its dyno graphs show gains of upwards of 20whp in the midrange, while again, not increasing the peak whp much. Fantastic drivability increase. Have had this 5+ years with no component failures as it's OEM diameter, leading me to believe that the underdriven Fluidampr on my 6 was likely the cause of my AC compressor failures.
