Over boosting probs

[mikeycar500]

Hey long time no talk I have been out of the festiva game for a bit, life and all but I am back I have the arm drops I. Two days and the vj11 on this motor is over boosting to more then 20 psi I do not have a boost controller just running the waste gate pressure which should be in between eight and 10 pounds
At a loss here any help to get me to the track would be muchly appreciated

How big is the exhaust?

[mikeycar500]

2.5 all the way back
By the way this is Aaron brooks old car I have had to change the motor as the over boosting blew the one that was in it I am on my last motor so can't kill this one
I have changed all the vacuum lines I have searched and patched and blocked any holes I can't think of any reason that it would be over boosting the wastegate works

Cut the exhaust put a piece of 1.25 pipe in ,at least a foot long . Some place closer to the engine .

I just went through this!!!! have you seen my new thread

Lucifer gets a new turbo setup.

Dont overboost past 16!!!

My issues came mostly from my leak in the line to the controller. I found the leak, set the controller to it lowest boost setting and would let it creep up to around 15psi. I had a ø2" open down pipe 6" long! I blew 2 jv14 in a month. the 1st one was good the 2nd was not so good at best. Now im going to an all new turbo setup because i wanted away from the jv stuff.
