shim the CDM wastegate
 

anyone cheap enough to try and shim there wastegate? if so what did you use and what was the outcome.. i got a 5.8 psi spring i was thinking about finding a large washer or somthing to try and bump it up to 8psi or so

Probably just easier to make or buy a boost controller.

Yea, you can use a few washers to shim your wastgate (im assuming where the bracket bolts to the turbo)... I did it on mine once, and it worked well..
1 washer upped me about 2psi...

I also bent the bracket once, to up the boost. It worked, but you have to watch out not to get the arm crooked, or it will bind.

Re: shim the CDM wastegate
 

he is talking about a external wastegate and your are talking internal, but if you find the right size washer it should work

Re: shim the CDM wastegate
 

yuor right, i just remember how gay it is to take them apart

Re: shim the CDM wastegate
 

It'll work, but just check to see that the valve will still open 100% and not bottom out from the washers.


You might get boost creep if that happens.
