^^Lubo, more highly modified engines would benefit even more from balance shafts.
OP: The belt causes very little drag, and leaving it off is going to reduce the average life expectancy for bearings, some get away fine, and some don't. Me, I'd leave it. There are plenty of people that have had theirs gone for a long time with no problems though. It is up to you.

Re: Balance shafts on h22? (Lubo_25)
this was not a duscussion on whats more beneficial for modified engines he has a stock motor and he should leave them in thats all i was stating...from driving preludes and accords they have no affect on any performance or drag...but to each their own

I agree, the balance shafts just reduce the engine noise and vibration inside the car, thats all they are meant to do. Personally I prefer to them taken out, but you can just take the belt off and gain back some parasitic loss. You'll gain more efficient oil flow by takingn them out.

That is incorrect, balance shafts are in place to combat 2nd order harmonics on the crankshaft, and therefore contribute to longer bearing life.

Re: (mgags7)
youre absolutely right about that for the modified engine part...but yeah they're mainly there for bearing life which is something many dont know about the balance shaft system ppl want to just "remove" them because they heard from so and so they gained 5 horsepower!!! which means ****** **** on these motors...

Who cares about 2nd order harmonics when they are obstructing oil flow. I'd rather have them not splashing oil all over the place so it can go through the bearings and into the oil pan as efficiently as possible.

Well, quite obviously, every car manufacturer that makes 4cyl engines over 2l does. You will find balance shafts in every single one.
I'm sure you don't, but if you did know anything about what you were speaking on you'd know that 2nd order harmonics are, in most cases, the "worst", meaning they have the largest amplitude, and this is a bad thing considering that these are distortions in the crankshaft. I don't know where you're hiding on centennial campus but if it is any sort of Engineering you'll soon learn this in class.
Also it is obvious that you get plenty of oil pressure with them in, as Honda's engines continue to last into the 200,000 mile range in their stock form.
...and just a side note, if you're going to try an argument, make sure your info is correct first. Balance shafts are nowhere near the sump, they don't "splash" oil all over the place. They, just like any other shaft, need oiling on their journals. When you remove them, you plug the oiling holes, and you gain a few psi of oil pressure.
Like I said in the beginning, they're there for a reason. It is your decision if it is worth the risk.

We have dyno proof on this board of it only being about 2-3whp on a 200whp engine, so 1% gain. If you can show proof of yours I'll be glad to accept it as true, that would be about 2%, huge gains.
Until then, however, keep the bs to yourself.

Are you some kind of "know it all" college sophmore? I'm glad you can read wikipedia but they don't have all of the answers. The balance shafts are only about 3 inches away from the crankshaft and can catch oil falling from the cylinder head and splash it toward the oil coming out of the rotating assembly.
Most people on this website are enthusiasts or build their car for more performance (especially if they are inquiring about this), and I would say with the added stresses on the motors internals to generate more hp greatly justifies gaining additional oil efficiency. All I'm saying is the oil wasted on those balance shafts could be better used somewhere else.
Also, If you build the motor with lightweight pistons and rods, your going to have much less harmonic vibrations. It would probably offset it too much.
By the way, I'm not even in mechanical engineering, but I feel bad for you if this actually is your are of study.

So you're the expert now on the stresses added by such modifications and your knowledge qualifies you to make the ASSumption that a few lbs of oil pressure in an already over-engineered system is more of a benefit than reducing harmonic distortions on the crankshaft.

The weight of the pistons and rods have very little to do with the situation, do you even know what you're speaking on?
The timing of combustion events up and down the length of the crank is what causes the harmonics, not the weight of the pistons and rods. Their added gravitational force on the crank is uniform over all 360 degrees of its rotation and therefore does not create any distortion on the level of what we're speaking about here.
I urge you to go read about it, you'll learn something. Right now, you sound like any other idiot who read a thread on blocking them off. You'll need a better argument than a few psi of oil pressure to "prove" anything.

I'm not in mechanical engineering bud(EE). I probably should have been though.
Anyways, harmonics are harmonics, whether they're distortions on a crankshaft or EMC waves coming out of your cell phone antenna. I'm not speaking out of my *** here.

I dynoed this myself, on my car (217whp NA prelude back then) in back to back runs. no balance shaft belt made 2-3hp across the board. wooo. Kinda stretching for gains, it's like taking off your PS belt, but with worse consequences.
The car also revs faster which maybe why you say something silly like 8-10hp, but I already documented the facts a long time ago.
Stick to what you know.

This is incorrect . Sorry, but I continue to find flaws in your logic. The harmonic balancer counters vibrations caused by the inertial moments of the rotating assembly. By altering the mass of the rotating assembly (remember mass is directly proportional to momentum) as well as increasing cylinder pressures produced in the cumbustion chamber changes the amount of correction needed from the balance shafts. They are designed to work with the stock engine. Once you slap in your crower stage 3 cams you are now causing greater cylinder pressures and creating more vibration. Your balance shafts then become less effective. But that additional strain on your valvetrain and bearing journals could benefit from the oil wasted on the balance shafts.
So your a junior, wow, very impressive, you made it throught your sophmore year, you must be one of the smarted mf's on the planet.

Re: (gogunkergorilla)
you were still making up HP numbers, it really kills your credibility. I had ENDYN pistons, some rods I forget everything lighter on the rotating assembly and only 2-3whp

We're not talking about the harmonic balancer, that is on the end of the crank, on the crank pulley, the balance shafts have a different purpose.
Dampers store and release energy to diminish harmonics. That is the function of the harmonic damper.
The balance shafts are geared so that they spin at twice engine speed, aka twice the base frequency of the engine (RPM) in order to cancel out 2nd order harmonics. The weights are setup in regards to firing order so that they cancel out these harmonics.
The harmonics themselves are actually created because of the difference in acceleration of the pistons on their upstroke and downstroke. After further thought, you're right, lighter pistons have a small effect on this, but it is maintained that in such long-stroke engines, the difference in piston acceleration is what causes the harmonics, weight is an afterthought.
Your explanation of the angular physics just sounds like an uneducated stab at an explanation. For what it's worth, the whole bottom end as a unit has one moment of inertia. Go get a physics textbook.
I'm done arguing about this with you, because obviously you're being cockstrong and closed-minded about this. Also, if you're going to argue, read first, argue next.

You're the one that asked, I didn't just start touting my education, and I'm not "bragging" about being a Junior. Resorting to personal attacks in debate is un-called-for anyways.
