balancer shaft delete question

[slick]

but its not really needed by what jose says and hell he tunes for a living so i would trust him

[wed3k]

my entire car shakes like it is about to fall apart.

I haven't been convinced this is a worthwhile mod. Sure it has been done over and over, but I haven't seen any data proving it's worth.

You will experience more vibrations, it WILL cause the engine to vibrate harder. Especially if you have solid motor mounts...as I do. I can't imagine it vibrating more than it does right now, but without the shaft...good grief


As far as longevity, I believe it really just cancels the vibs that YOU feel. The crank still experiences them...I'm not sure about that though.

Gains were posted on H-T a while back. I'll see if I can find the dyno. But there was 3whp or so up top.

And it doesn't vibrate anywhere near as bad as you think. Father Time has ESP mounts all around, with a poly insert on the front and you can't even tell the car is on during idle. He has no balance shaft belt.

Built H/F's eliminate them for christs sake. That not only free's up power, but creates more oil pressure.

3hp is easier to swallow for me...I know that 3 to 5 isn't much of a difference but it is to me. Good info...and higher power (no matter the amount) would equate to easier reving I suppose.

Mine only vibs good around 1000...below or beyond it's nothing.

It's not hp, it's whp. Intakes barely give you that much power on a stock motor.

This is free.

Well I'd still like to see the dyno's but I trust what you're saying.

So would need the kit or can you really just take off the balance shaft belt? If so, do you really need to install both belts before taking the balance shaft belt off? I don't see why you couldn't just install the t-belt alone if this is the case.

The only reason why i installed both belts before i removed the balance belt is mainly just for piece of mind that nothing will be rubbing and everything is in OEM alignment.

[d112crzy]

I never install the balance shaft belt. Theres no need to.

[StinkinLincoln]

IMO its not worth it!!

Every review that I have read said that the engine rev'ed up a lot faster once it was removed. I plan to remove mine.

The top end RPMs feel smoother with the BS belt removed.

Also, BS belt removal will not cause your car to shake at idle. If that happens, you have problems elsewhere. I am back to a stock motor, idling at 750 rpms and I'm fine with no BS belt. Nor will I ever run on on a CB7. There are just too many advantages to not having it. Plus, it makes Tbelt jobs even easier and you spend less on parts.

lol Im gunna remove mines

but still gunna add the retainers for the front/rear seals

it cancels out harmonic vibrations caused by the crank rotation and combustion. Totally unrelated to emissions and will not change your readings for smog. just remove the belt. If your doing the timing belt as well i suggest using the balancer belt to get everything including the rollers in alignment and once everything is tight slide the balancer belt off.

It isn't technically harmonic vibration. That would imply resonant frequencies. It cancels out the 2nd order vibration inherent to all I4 and flat plane crank V8 engines. It isn't structural, it is for smoothness.

On an H22, it frees up about 3-5 WHP, due to the lower parasitic drag, and partly due to the lower inertia. The other plus is that because you are removing approximately 17lbs of rotating mass, the engine revs more freely, just like it would with a lighter flywheel.

It DOES make a difference in the response of the engine, although it is not mindblowingly faster or anything. Just revs a little better and doesn't seem to fall off quite as much in the top end. Probably a marginal MPG gain associated with it too.

It won't do anything structurally to the engine.

It won't do anything structurally to the engine.

So you are saying this will not effect the longevity or reliability of the engine? I may just do this when I swap cams
