i would imagine that this would happen... specv guys had to add 1 qt of oil as well... but what did you replace it with in its place? did you just cut the bolt and left the balancer intact?
I'm not sure what you're talking about. The windage tray and both shafts are removed, and the oil galley is plugged.

Uh, no. Remove the stuff. Nuff said. Shafts are gone. Gear on crankshaft now has nothing to drive. Get it?

My post below on another thread on this topic:

navylife59 wrote:
The balance shafts are driven directly off the crank so why do you need a "Kit"? The balance shafts are there more than just for creature comfort. It is an inline engine, as such, there are no counter-oppossing forces to cancel out the inherent harmonic distortions. HD can be real engine killers if left unchecked. If you remove BS then you wil need a full balance on the rotating assembly, forged assemblies, and a fluid dampner to make the motor last.
---------------------------------------
adg016's POST

Wrong. These are second order harmonics that vibrate the block and consequently transmit vibrations into the cabin. This is something most consumers will not tolerate. They bear no deleterious effect on the internals at all. If anything the shafts put more strain on everything inside, since other parts are stressed having to spin them. In addition they churn and aerate the oil.
------------------------------------
Yeah, it vibrates. I don't know if it would bother you guys or not. I have no idea what your tolerance level is. You have to remember I also have solid motor mounts and my car is a race car. You may elect not to do this for a daily driver.

question...the oil pump has a chain that is driven by those balancer shafts along with the timing chain itself going down to the gears so how exactly did you removed the balance shaft assembly and not affect the oil pump and the timing chain?

Just like adg016 said it will harm the internals if you have not balanced the rotating assy and installed a fluid damper.

hmmmm. would the horse power difference increase exponentialy. i.e. on a 160whp tc you get x amount more hp. but on a 400whp tc you get y amount more?

I never said that at all. Some moron did and I corrected him if you read my post above in its entirety.

Haha. But let the record reflect that I never said that. In fact, quite the opposite.
