Engine balancer, any need????
 
Guys WTF is this and do you need it??? My tuner is busy with my engine rebuild, reckon it might be an engine balancer. They took it out on the race cars. According to them serves no function, and put's strain on the crank. If removed will help the gears spool up quicker.

If you remove the sump this was bolted to the crank??? I'm keen to chuck it off and see? :kabong:

Many people on here have removed the balance shaft. It's incredibly heavy. All you need to do once it's gone is plug the oil hole that it connected to.

That's right we'll plug up the hole for the oil feed and yeah it is heavy! What a waste!

Thanks for your reply and & confirmation!

For them to say it serves no function is a ridulous statement. Of course it serves some function otherwise they wouldn't have put cash and time into it to design it.

Many people remove this thinking that its what cause the engine to blow up via cyl 3 most of the time, as that is where it is located. IMO there's no proof of this. Is it necessary? No. Is there a benefit of removing it? Maybe..you will get more vibration, but a bit more power too. I wouldn't worry about it.

cool thanks

he he you lost me Lenny! Why you awake still working on your Speed??

It actually doesnt balance anything, it simply cancels out vibrations from the natural unbalance of a inline 4 cyl engine that cannot be balanced. When you take it out you begin to feel the vibrations that were there all along, so from a mechanical standpoint, its useless junk, but from a nvh standpoint you might want to keep it because the power gained from removing it isnt noticable.

In a racecar, it might be worth a second or two at the end of a road course or roundy round type race which makes it worth removing.

From a engine blowing standpoint, its almost laughable that it could cause a blown engine. From a block strength standpoint it might be worth keeping because that 14lb of iron is likely strong enough to keep the block straight.

EDIT: FYI, if it is already removed DO NOT REINSTALL IT!!! There has been ALOT of major engine fail from reinstalled balance shafts.

the motor has not been installed yet, so might just leave it off. Would you, are you running yours in terms of the NVH standpoint?

The NVH part might be a issue on the long run....
Let me know thanks.

I removed mine around 60k miles, I have 114k miles now. There is a definite difference in nvh with it removed.

If it has been removed, it should not be reinstalled due to the risk of complete engine failure if it is not timed, centered, and shimed perfectly.

In other words.......... it is off in the pic....... leave it off.
