hey

I'm half way throught turboing my 4k rolla but I'm unsure on how to lock the dizzy

ive got a 3k and 4k dizzy here which one would be the best to use and how do u lock it.

thanks

Do you want to lock the mechanical advance weights, or the vacuum advance/retard?

 

What is the advantage to you in not having the ignition advance with revs?

 

You can make it advance less by altering the slots under the dizzy plate where the arms run, and you can make it advance slower by changing the springs on the arms. You can stop it retarding on acceleration by screwing through the base plate where the vac advance/retard rotates it.

 

But if you lock it at 10deg advance at idle it just won't rev.

You could lock it and go an electronically controlled ingnition system, just requires some electronics skill, excellent for you want to do. You can modify the timing as you drive and as you dyno and things like that......here's some info http:// [url=http://www.rollaclub.com/board/index.php?showtopic=34948]http://www.rollaclub.com/board/index.php?showtopic=34948

the 3k one is easier to lock. Pull all of the top out of it and you see a couple of slots with some pins that run on them that'll be on the inside. If you want to do it quick and easy just use 4x small cables ties to stop the pins running in the slots.

 

Then set the timing at 20-25*BTDC static. It won't like starting too much on cold mornings but it will like to rev,....espeacially on boost. ;)
