I installed a Fluidampr on my EJ205 as a reliability mod and I love it. It might be a stretch but I feel like I'm burning less oil after. I think MotoIQ's article comparing all three of these on a relatively stock BRZ speaks volumes; despite the extra weight the Fluidampr made more horsepower on the dyno and showed a much smoother power curve.

I swear by fluid dampener on EVERY motor I've ever build! reason being the balancer/pully affects the harmonics of the crank and thus affects the valve train. this is why belts are preferred as they help dampen these harmonics. This harmonics can cause tuning disruptions, valve bouncing, and so many other weird phenomenon leading to destruction. This was an awesome very well informative video with a great explanation! 10/10 said it like you read the same books or followed the same builders!

That's a weird story. but they swore by harmonic control and dampening. But seemingly all engines have this same combustion harmonics and these harmonics VSTLY effect the engine life. Koenigsegg free valve tech and some new2 machining styles have made some insane motors with near zero harmonics and ABSURE power for their size because of it.

I paid $366 for my Fluidampr pulley almost 3 years ago. I haven't installed it yet because I'm probably going to save it for my V9 EJ207 that's on standby in case my EJ205 pops. From what I read while in the rabbit hole, the lightweight pulleys are worse in the long run if you are combining them with lighter flywheels. You will start to notice that the daily driveability will suffer, meaning your revs will be all over the place. OTOH, if you track the car, then you'd be better off because you're not trying to maintain a set speed limit. The EJ's crankshaft is also balanced with the damper installed, and by installing a lighter pulley, you will increase oscillations. That is not a good thing. IMHO, I feel that a lot of newer Subaru owners comb over the aftermarket sites and look for something that claims more power but doesn't break the bank. Hence, the slick marketing for the lightweight pulleys. Just my .02 cents. Anybody is welcome to do as they please. Just do your research.

100%, I left out lightweight flywheels from this intentionally. Personally, I stick with OE. When possible, I will keep the mass on the crank to help with inertia when turning over.

I also have to do the timing belt... Oh and let's not forget about the OE cam pulleys that crack💸💸💸

My assumption is that this is that rod failure typically happens from "bigger booms" after say 350 to 375 torque. Would a fluid damper help? Hopefully I asked the question right. Sorry if I didn't in advanced. BTW, I've learned so much from your channel man. Sooooo much. Thanks big time.

The correct pulley makes a big difference. I have a cranky old man (machine wizard) building a Chevy 327 for me, getting fully balanced and all. He still recommended the 10in 350 HB over the 327 6in stocker. Bigger, heavier one worth 15hp in the mid range since it smooths out everything a lot. The actual harmonics from the combustion pulses causes hp loss cause it starts to resonate and shake the engine apart

As per what a dampner is, most engines do have a "dampner" and it would almost always take a cross section to see how much rubber or composite is used to soak up vibration and resonance. Lightened pullys (as a a dyno technician) I have noted that in about 30% of circumstances INCREASE the amount of resonance past having none, due to essentially adding a tuning fork to the end.

Fluidampr is the optimal solution no matter your power level. Go to their website and see the data.Properly collected data does not lie. Lightweight pulleys increase the opportunity for secondary vibrations to bomb 💣 destroy your engine. That is dynamics and materials properties facts not an opinion. Given most modifiers go for substantially more power than OEM a crankshaft damper that is designed to work effectively over an even larger power band and sustained higher revs is a no brainer to my way of thinking.

The rotational weight of the fluidampr is less than OEM. There is a weighted inertia ring inside of the fluidampr that is suspended in fluid. MotoIQ did a long tech video on fluidamprs and provides better information and resources. After installing on my EJ, I noticed improvements in every area of driving. From Idle to redline, this made my Forester better. Mike from MotoIQ touches on a little discussed topic of the sensors picking up the cam and crank angles more "correct" as opposed to the whip forces on the cam and crank from combustion. He is not kidding and this is known is racing circles. The same way a faster ECU or one with better OS (if using older hardware) can do the ignition timing better and be more precise. The reduced whip of the crank and subsequently the cams means it is more accurately reading the correct cam positioning as an example. Go one step further and take a look at images of exotic engines and see a quite large and familiar crank pulleys. I have spotted a few. Additionally, you can find harmonic dampers with similar tech and goals in detailed pictures of certain F1 engines (take a look at the incredibly intritcate cam harmonic balancers as an example).

I grabbed a fluid damper for my eg33. Did a bunch of research as well. I paid about 600 canadian for mine and had to wait 6 months for it to be made. But was worth it.

For an EG33 I wouldn't really worry about it, the boxer 6 is one of the best naturally balanced designs ever and they have a relatively short crankshaft torsional twist isn't usually an issue. I have researched using fluidamper but couldn't find enough reason to bother. I am not an expert by any means and anything you do to your build is good for you, I know you sure didn't make things worse.

I will also add the crank and stock rods are both forged in the EG33 even if the rods are a bit too thin so having those forged also helps keep things going fine without the vibration damping. I ran that exact Perrin LWCP on my SVX for 8 or more years but I was also running the stock ECU with Chip for fuel and timing mods that got me about 200 AWHP with stock injectors and some supporting mods, I also changed the tune and put in Nissan MAF and 550 Sti injectors without any issue but only ran that for a couple years. never did get a chance to re-dyno it. i was also running a sti 6 speed.

@@black69camaro2344 agreed. They are well balanced. But the stock one I had was starting to separate. I also found info that when you are loading the crank with higher torque (more than stock obviously which is the end goal) the fluid damper helps with the accessory drive stuff not getting the shock transferred through. Unless I misinterpreted that part.

Question: what are your thoughts for the FA? Now this platform does not come w a harmonic balancer. Oem pulley is already light weight compared to an EJ. Grimmspeed and maybe perrin finally came out with a ver. For the 2018+ wrx. I am at 36% power increase over stock. (324 whp, 336wtq)

Agree to disagree. I didn’t see any hp increase with the aluminum pulley. Rather, I saw better throttle response on the bottom end. Kinda the same thing you experience with a throttle body spacer and/or intake spacer. But for different reasons.

Very few motors were externally balanced. The Chevy 400 was, all other small block chevys were internally balanced. The harmonic balancer has nothing to do with balancing a engine. It is there to minimize torsional vibrations . The longer your crankshaft the more you need one.The more power you make the more you need one. Internally balancing an engine is nothing new.

this video is some weird science explaining what isn't going on accurately... crankshafts are built for torsional twist, its what spins the damn air pump. it's the reciprocal ups and downs (or side to side, for you head gasket eaters) in relation to the spinning that has imbalances to dampen out. Imbalances that stem from anything; one cylinder getting a little less air due to a casting defect, an injector that has one clogged pore, a stubborn chunk of carbon on one piston, coolant design etc. Without protection, the harmonic vibration is free to roam, perhaps resonate elsewhere and worse; amplify. The crankshaft wants to wiggle as it spins and a damper serves to absorb those vibrations as they happen without letting them pass the rotating assembly. Going from a stock damper to ati/fluid with harsh engine mounts is a good demonstration of this. Stock rubber bound pulleys dont typically fail by falling off, they slip and slide and the timing marks will lose their place, if you have a timing wheel that is attached to the outer sleeve, you will lose power due to the crank sensor being a dummy switch. if you ignorantly retime your engine to slipped marks, it may be excessively mechanically retarded or advanced depending on how far it's slipped and wont matter for long anyways. fluidampr and ati are of different design but have a more broad range of imbalance-caused harmonics they can dampen better than oe through focused design. OEMs made something simple that works and can be installed in millions of cars on the cheap. Aftermarkets in pursuit of horsepower alongside longevity made something that worked better at an individual unit cost. Unless they're balanced specifically to the engine, lightweight pulleys seem like marginal gains and bling factor for something that has a complete lack of provisions for an integral part of how your engine doesn't tear itself apart as it spins 100+ times per second.

you need to remember that machining evolution effect on primary harmonics is one thing but secondary harmonics are another. secondary harmonics are mitigated by design and not by machining. It's balance shafts, rod to stroke ratio. The rubber filled pulley is good for its intended purpose, not introducing resonant stress into the auxiliaries or crankshaft and avoiding extra torsional twist caused by the auxiliaries. By default the front pulley is mostly a counterweight for the flywheel. You should go with the rabbit hole anyway because where fluidampr is a good investment and good for your engine OEM is in most cases adequate for any abuse you're giving it as long it's a good one and not broken due to it being mostly dependent of engine design
@teemuuusitalo7987

so altering the engine design (valvetrain, redline) is a good reason to change the damper due to how resonance acts (easiest way to think of it is octaves) and slapping forged internals and a big turbo isn't

I replaced my original oem crank pulley with the grimmspeed lightweight one. Oem was so rusted and I was worried the outer ring was going to separate from center. Went with grimmspeed one because I didn't like the perrin one having spokes vs grimmspeed being a solid piece. No issues so far, about 10k miles with a ~300hp stage 2+ stock motor, 04 wrx. I'm pretty sure I'm at the power level that it doesn't really cause any harm.

Now this is my argument on lightweight pulley would be. If you where spinning the LW pulley faster than the crankshaft and the fly wheel, that would in theory create more wear on the bottom end (bearings, crank ect.) I’m no scientist but I feel like the LW is going to cause more minor wear even on light bolt on cars. Which will cause a lot of wear in the long run.

I need lower end torque, i thinking lighter pulley on my stock engine. Mine just solid metal, no damper or rubber. There is no aftermarket for my engine. This might be funny, but i think it will work. Could i just cast my stock pulley using solid fiberglass or carbon fiber, keeping the metal bushing for mounting. I could use alumunium on the side as heat shield. I think even using woven fiberglass and epoxy it will be significantly lighter.
