BULL. ****. Granted 7.5lbs is insanely light, but you just have to shift faster.

Stop posting your made up number and stop acting like anything you've contributed to this thread is useful. You're simply posting BS that is going to confuse people looking for real information.

This is why I can't stand this forum sometimes. How many lightweight flywheel threads do we have - a couple hundred? And yet, every time it seems that maybe a new thread will commence unpolluted, all the fools come in and **** all over it.

Honestly, what the f*ck are we even talking about? What flywheel? How many pounds? How far out is the center of mass located? How much extra mass did your aftermarket pistons and rods add? How much extra momentum can you retain having ditched your accessory belts? Is your aftermarket clutch heavier or lighter than OEM?

You people with your lack of fundamental automotive knowledge make me sick. You know why the factory flywheels are so heavy? It's because Hondas are made for everyone - including octogenarians, women, FOBs, and all the other tards who can't drive. The flywheels are heavy because Honda knows the mass consumer public is comprised primarily of slack jawed yokels who need a full second in between shifts for their tiny little brains to register what's happening and calculate what gear they should shift into next.

Let's recap.

Pros of lighter rotating assembly:
1. More power across the whole rev range
2. Faster acceleration

Cons of lighter rotating assembly:
1. Possibly not enough momentum to launch on large slicks (you run out of revs)
2. Going too light makes you shift too fast and your trans will suffer
3. You must have an IQ over 100 to figure out how to drive your car properly

light flywheels are a waist of money for turbo car. end of story. it makes it a bitch to drive and the gain(if any) is VERY minimal. not to mention that it throws off your entire engine balance which you dont want.

Ohhhh, I get it - it's right because you added "end of story" to the end. I guess I forgot that when you add a turbocharger to an engine, it's suddenly free from the bounds of Newtonian physics. Rotational kinematics? No way! I've got a turbocharger!

Well "zex_cool," there is absolutely nothing wrong with running lightweight crank pulleys. Although, given your substandard IQ, lack of automotive knowledge, and complete failure to understand elementary kinematics, I'd say you're probably confusing lightweight pulley's with pulley's that don't compensate for engine harmonics. In which case, you should probably just kill yourself.


Who else wants to argue me with? I assure you, this isn't an argument you can win because you're flat out wrong. Physics is not subjective.

I have one and it revs like a motorcycle and stays in boost. I also road race my car and it feels great at the circuit. The only thing I don't like about it is drving in traffic.

just because you don't know how to drive, dont blame it on a flywheel.

so your saying a stock itr flywheel is horrible for an itr because its lighter than a gsr flywheel?

also i guess all the pro drag cars that run a twin disc are making their car worse off because the twin disc's flywheel is lighter than the oem piece?

a lightweight flywheel is not a necessity, but is a nice mod for people who want a more efficient motor

take your car and run it at the track, then take your car put a lightweight flywheel on it and run it at the track again, i bet your trap speed and times are faster with the lightweight flywheel

Tell me, what part of this post pertains to this thread in ANY fashion? I don't care who you are, what kind of car you drive, or how fast it is. On this planet, on this plane of existence, with our known, unwavering laws of physics, it is a pure scientific fact that lightening the rotational mass WILL make more power, and hence produce quicker ETs. "End of story."

"I" don't say it, rotational kinematics does. We've been over this; just because I'm defending science doesn't mean I wrote the laws of physics. I simply have a firm understanding of causality, whereas you live in a world where you can bend the laws of science to better suit your arguments and/or opinions.

Honestly, you're probably one of the least intelligent people I've ever had the pleasure of arguing with. The backbone of your argument is a logical fallacy...?

Exhibit A:
1. A lightened flywheel makes a car faster
2. My car is fast
∴ My car has a lightened flywheel

Exhibit B:
1. Lightened flywheels add power
2. Fast cars need power
∴ All fast cars need lightened flywheels

There's actually a word for people who don't understand logic: stupid.

I agree that you can go fast with heavy flywheels.But that doesn't mean you couldn't go faster with a lighter flywheel.I have never heard of anyone using a heavier than stock flywheel to go faster in a race car.No one uses heavier tires/wheels in a race car to go faster.

Just wondering, have you tried a lightweight flywheel? Your sixty foot times would drop some (and launching would be a little trickier), but you would make up for it over the rest of the 1/4 mile. Your trap speed will be higher and your ET will be lower. Just thinking that if you are trying to break in to the 10s every little bit helps.

To answer the original question, NO, you do not lose torque with a lighweight flywheel. With a lightweight flywheel you get less parsitic loss in your drivetrain allowing MORE horsepower and torque to the wheels. There are some cons, but in my experience they are far outweighed by the pros. I love my 7.5lb flywheel and will not be going back to OEM.

im sure there are pros and cons to lightweight flywheels, but for me personally my lightweight flywheel was one of my personal favorite mods. I have no problem driving it on the street or otherwise. I just spent three evenings in a row driving around getting used to it.

CX-T

Lighter is better, but the stock flywheel is good too. I use a stock flywheel on my setup and I like it. So you don't loss torque.

if your going to try and maximize your power with your d series im sure a lightweight flywheel could help you more than most... it will help power throughout your rpm's .... although not necessary (stock is fine like you mentioned), a lightweight flywheel will help your efficiency and put down better times/trap speeds

my light flywheel gives me 50whp bullshit.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Let me begin by saying that we have always called the pulley on the accessory drive end on the Honda cranks Harmonic Balancers. People never seemed to understand what we were talking about and so the word "pulley" was frequently used to avoid confusion. If you look carefully at a Honda "pulley", you'll find that it's not a single piece of metal. Typically, there's a nodular iron or steel hub and another "ring" of iron or steel surrounding it containing the belt grooves. The two parts are joined by a rubber layer, which is highly compressed and sandwiched between them. Why rubber? If you notice, many four cylinder engines over the years have used counter rotating shafts to help make the engine "feel" smoother. Reciprocating internal combustion engines and especially in-line four cylinder versions, all produce shock pulses, which are very apparent to the occupants of the car. Every engine produces a shock pulse each time an individual cylinder fires. So, in the case of the four cylinder variety, there are four large individual pulses for each 720 degrees of crank rotation. Each time there's a pulse, it causes the internal components to do a rapid acceleration-deceleration event. When you consider the mass of all the internal components and visualize all these parts stopping and starting during their reciprocating and rotating motions, the additional stress "spikes" tend to make it all the more reason for one to wonder how any of it can work for any length of time. The harmonic balancer is made with the rubber coupling so that, when the individual "spikes" occur, the inner portion may move with the crank, but the rubber connected outer ring's mass helps prevent the hub and crank from going as far or as fast during the spikes or pulses. Remember that the outer part had considerable mass, so it tends to want to stay in motion at the speed that it's traveling and that's why it can prevent excessive harsh motion by the crank and other internal parts. To put it simply, the harmonic balancer is a shock absorber for the engine and thus prevents the individual pulses from destroying everything in the engine. A quick bit of history; Back in the late '70's, all the Pro Stock engines had been reduced in displacement to allow the cars to weigh less. At that time the vehicle weight was based on engine "type" and total displacement. Typically, the engines were in the 330 cubic inch range and running 10,000 to 11,000 rpm was normal, especially in high gear at the traps. There began to be a lot of engines that were "exploding" their harmonic balancers on the big end. Aside from cutting the steering in half and blowing the front tires, large hunks were also finding their way into the grandstands and there were numerous injuries, many of which ended in death. NHRA immediately mandated that solid "balancers" were to be used from that point on. Keep in mind that a balancer can't be solid and function properly, but the rules were the rules. Moroso and a couple other companies who were tight with NHRA began making aluminum billet "balancers" immediately and everyone bought them so they'd be legal to race. All of a sudden, racers were getting only 10 passes from their crankshafts, which had previously lasted an entire season. Initially, most people thought the cranks were "bad", but after destroying engine after engine, a few knowledgeable engine people figured out where the problem actually was coming from and several companies that were capable of making functioning harmonic balancers sprang up over night. They are all still in the business to this day and their units are actually much better than the factory units of years before, as they are made from premium materials and optimized for high rpm applications. With this short bit of history finished, I'll begin to wind it up by stating what we do with the Honda engines. If the balancer has more belt grooves than the application needs, i.e. the power steering pulley, we machine it off. When it comes to the the pulleys that are actually a part of the outer portion of the balancer, we leave them intact. This procedure will not lighten the unbalanced hub substantialy, but the outer balancer ring will keep all its mass and function correctly. I also need to say that a large driven mass such as a blower or alternator, can have a slight dampening effect, but to actually work properly, the belt connecting the components to the crank would need to be 4" to 5" wide and the belt tension would be so great that it would wear out the number 1 main bearing as well as the bearings of the the driven parts in short order. It's especially important to keep the balancer "as is", if you're running an aluminum flywheel. The reduction in flywheel mass can also increase the pulsation shock strength and a higher level of vibration will immediately be observable. So if you lighten the flywheel,it's absolutely more necessary than ever to maintain the mass or the harmonic balancer. I realize that there's a lot of hype out there where manufacturers are promising this and that. The oversize crank pulleys can drive other geared or belted components faster due to the diameter ratio increase, but if you're deleting the balancer in the process, the short and long term side effects are going to hinge on your decisions. Larger diameter pulleys for the alternator, power steering and any other belt driven accessory are good ways to slow the speeds and drag of the those components, but when doing a large diameter crank pulley, the larger pulleys should actually be designed to fit "over" the stock balancer. Perhaps, someone will begin to make some good quality "functional" balancers some day, but until they do, you need to proceed carefully, as some good looks and minimal power gains can be off set by a ruined engine. I'm sure that there will be some fall out regarding what I'm saying here and to that effect I need to remind everyone that we do not manufacture hubs, big pulleys, or harmonic balancers for Hondas and none of what I've said is the least bit politically motivated.

And yes, any engine with a non-functional hub or balancer can ruin the crank driven oil pump and a whole lot more. </TD></TR></TABLE>

I dont think a lightened flywheel would yield many more/less hp in your dyno gear (4th) but I have heard that a heavier flywheel builds boost slightly faster than a lightened due to increased load on the engine.
