Hi everybody ,
Hi Andreas ,
I want to cancel balance shafts too,
but Im hesitate generate more detanation on the engine after 6000 rpm , what is your explain ?
do you know, who is make this ? and result ?
Knock sensor maybe sens that vibration like detonation !
I was disable EGR too ,
I dont use it .
Becuse ,I know ,EGR is only minimize NOX gases only and give us fuel economy .
BUT ,Can you read following adress ?
about detanation .
all the q4 and lancia based engines have balance shafts...DO NOT take them off they are essential to keep the engine smooth if youve ever driven one with the balance shaft timing out by just one tooth you will know what i mean.!
Have to disagree with you there, first garage that did a belt change on my q4 put the balance shafts in 180 out of phase, I didn't even notice. I'm sure they do make the engine smoother, but taking them out ain't gonna do no harm, and you will be hard pushed to notice they are not in.
i must disagree further i have done the timing wrong and i noticed straight away when i looked both were 1 tooth out.. is it realy worth the work you will have to block off the holes some how to prevent all the oil coming out...if you drive a fiat T.C then a lancia T.C the difference is amazing just from the balance shafts...!!!!
Jimybob, the point is that you just disconnect them, not remove them and by that also minimizes the risk of drivebelt jam for the camshafts. Personally I have no experience of disconnecting/removing balanceshafts, but I am sure it its worse to connect them one tooth wrong than to disconnect them.
Setting the balance shafts one tooth out would mean you have a pile of metal whizzing about out of sync with the rest of the engine meaning bad vibrations. Removing them / disconnecting them would give you an engine no worse that the 1.8 16v which has no balance shafts.
In summary a 1 tooth out balancer shaft would vibrate a lot worse than an engine without balancers!
If balance shafts reduce vibration and give a smoother engine, surely removeing/disconnecting them will give move virbation within the engine, and hence more stress and wear? i.e. gain 2 bhp and lose 20K of milage on the life of the engine?
