Turbo Balancing Etc

[benl1981]

Just wondering if the balancing is independent of each wheel? I.e. If you swap one wheel over that is already balanced to an existing turbo that was balanced would the turbo remained balanced with the new wheel.

I have a GCG with too large compressor wheel..I have sourced a blown one with the smaller wheel. Could I just take the housing off, undo the balanced nut and wheel and put it on the other GCG and hope the balance would be ok. I mean if the nut is done up to the same torrqu and relative location to the compressor wheel then that wheel should be balanced.

You can see on the attachments the spots where I think they have balanced it.

Cheers

as far as i know because its balanced as a complete rotating assembly and indexed before dismantling and re-assembling it will not be balanced even if you index it as per other turbo.

im going off the fact when i have watched the guys balance wheels/tyres at work, having extra weight on one side/wheel in turbos case can offset either more or less weight on other side. if that makes sense.

my answer is no, the different mass of the different sized wheels will cause out of balance.

if turbo wheels were balanced seperately then it would be possible but they aren't...

You might have something there RB30. THough they are supported by a bearing pack in the middle so I thought this might not be the case
