I'm running a turbo and was wondering if it is it better to lock the distributor in full advance or does it matter? What are the advantages of a locked distributor?

Tell what you think of my new upgrades.

 

It's better to lock the dizzy in full advance and then set your timing, so that the timing doesn't change with RPMs. This will allow you to have a constant and predictable timing, and help prevent detonation from the automatically advancing timing.

And the reason you lock it in FULL advance is because if you locked it at no advance, and your welds broke (or whatever you're locking it with) then you'd instantly inherit fifteen degrees of advance.... kaboom!
