Its hard to have too much Wastegate. It's easy to have too little Wastegate...

With that turbo if your trying to keep the boost down, run a 44mm. higher boost, the 38mm should be okay.

so the 60 is a complete overkill?

Check out the Turbosmart Big Bubba 52mm. I use to have a 38mm but I was getting some impeller flutter with it. No problems with the big bubba at 700rwhp.

like the man said, can never have too much gate. Course then the Gate is 1/2 the size of the turbo then, that would look "interesting"



Big Gate !

a turbosmart hypergate 45 will be plenty for that setup...
