Hi my dad has a 2005 dodge with a edge ez.does any one know if I can block off the waste gate. Would it be safe.


Thanks

 

Don't hold me to it, but 05's have an electric wastegate on them. Therefore I don't know if you can block it off. The EZ should have a boost fooler already on it. I searched it here on the forums and read that it does, but some people add a boost fooler anyway.

 

04.5-07 have an electronic solenoid on the wastegate. I dont think it would be wise to disable the wastegate. I run that turbo on my 1st gen with the gate tacked shut and i can make 36psi with stock fuel pin. The 05 should be able to make a fair bit more boost than i, probably too much.

 

With added fueling (Programmers) and blocking the WG you will run high Drive Pressures and possibly over spool the turbo.. If you have a DP gauge to watch DP's then you can adjust the WG rod tighter (shorter) in order for the gate to remain shut longer i.e. making higher boost but, I would not close it off completely.. DP should not be more than 1.5:1 ratio to be safe.. It all depends on how much fuel you throw at it and I'm not familiar with the Edge EZ's fueling potential..

Each complete turn (shorter) of the WG rod should in crease the boost by 1.5lbs and the WG should be set to open @ 23lbs by OEM specs.. There is a small pin through the rod and clevis you will have to drill out in order to be able to adjust the rod (in front of the jam nut).. The Electronic waste gate actuator is normally closed when powered so you cannot disconnect it or it will be open all the time.. The MAP sensor senses boost pressure and the ECM tells the electronic solenoid to open allowing boost lbs. to push open the WG actuator (set at 23lbs OE specs) and WG.. If you make the actuator tension tighter then the WG wont open until boost reaches the tension you set it at.. You will have to get a boost fooler or you will be throwing an over boost code constantly..

Connect a shop air hose with an in line air gauge and valve of some sort to the WG actuator boost tubing and you can set the gate to the lbs. you choose but, I would not go more than 35-38lbs.

I do not recommend doing any of the above unless you have gauges i.e. EGT, Boost & DP gauges... DO NOT TRY THIS If you don't understand how any of the above mentioned works..

Go to Competition Diesel.Com "tuning twins" thread and read, read, read..

Hi the problem my dad is having is the boost will go up to 28 psi then drop to 14 psi and stay there or go back up to 23 .and some times it is normal hitting 28 psi then droping to 23 and staying there

 

Maybe the MAP sensor? Does the engine surge up and down when the boost changes? If so I would say it's a fuel problem.. You cold wire the WG shut for temporary troubleshooting to eliminate the solenoid.. Just pull the actuator rod off of the WG lever and wire the gate shut.. I would change the tuning back to stock for the troubleshooting..
