A1 balance shaft belt

[93accdpj]

What is the downside of just removing the balance shaft belt? I heard of people doing it, but it's there for a reason or at least you would think so. Would it be better to do on a rebuild when you get the bottom end rotating assemblies balanced?

they say it revs faster

I can see some of the positve. A little less parasitic drain on the engine. Rev faster, micro hp gain, but how much differece does it make on engine vibration? Am I shortening the life of anything with out fully balancing the rest of the botom end?

I've had mine off ever since I did the headgasket on my car. It removes about 8 lbs of rotating mass, since those shafts aren't spinning w/ the engine crank. It's also good b/c you won't run the risk of walking your front balance shaft out...unless you already have that retaining seal. Vibration is minimal though, when you first drive it you'll notice a little, but you get used to it. There's no shaking through the cabin or something that dramatic though.

A member on here, I believe Owequitit, ran his F22 for 63k miles w/o any problems, it would've been more but he got an H22 swap done.

x2, I just replaced my timing belt and Jose (d112crzy) said I didn't need that balance shaft belt so I chucked that bad boy

Im getting ready to drop in my A6 cam, and IM so while I'm in there I'm just going to leave it off.

So I was trying to replace my balance shaft seals and the screwdriver slipped out of the maintaince hole for the rear shaft and not sure how to line it all back up. Should I try to line it back up(ideas for this) or just leave the belt off. I dont want a lot of shake and I want my engine to last. I know balancing it wrong might be worse than not balancing it at all.

I'm also curious about this. I'm going to the JY Thursday to find an A6 IM, cam and hopefully an A4 header. The ecu that i'll need I need to read up on more as to what models have them but since i'll already have the timing belt off i'll be able to get to the balance shaft belt and wasn't sure if I could just take it off and discard it or what all could happen by not running that belt.
