whats it smell like?!?

 

I was thinking the same thing.. the blue seal was definitely leaking. I did a boost test and left the wga line plugged in and covered the bleed hole on the mbc. My boost is wacko.. even with it cleaned out it's still not right.

I'm kinda suprised nobody for Forge has chimed in to this thread...

 

The corroded spring is to blame for the inconsistent boost levels. You will have to replace the spring in order to get the unit to operate correctly.

 

Oh, that brown crap is actually chocolate. It helps with corrosion. J K

Got rid of my RS BOV after constantly cleaning trails of grease, aluminum dust and shavings out of my turbo inlet.

Managed to convert the plastic OEM DV to hold just as good as the RS under high boost but operate normal under daily driving so I sold the RS

Perhaps the dude that made it broke the seal in rigging it

 

Probably left the bracket on it when he welded it so it f'd up the seals.. dunno. Car runs like crap and isn't consistent at all. FP WGA needs to hurry up... got a LT upgrade on the way as well.

 

Just safety wire the WG shut and run stock timing map until you get your part

 

If the actuator is not holding pressure when being pressure tested, the issue lies with the diaphragm possibly having a rupture of some sort.

We can provide replacement diaphragms free of charge for the life of the part.

The bottom blue colored seal is not supposed to seal completely. It is more a guide for the arm than a seal.

We are working on a way to prevent water ingress into the bodies of the units to prevent this rust colored grime from occurring, but this does not pose a functional issue for the units until we finalize something.

 

Then my question would be, do the NEW units with piston design for the Evo 9 turbo, will they have this type of problem??

 

What type of problem?

The piston units don't use diaphragms so there is no potential for diaphragm failure, so that being the only potential problem, no.

The water ingress may still occur until we make available a way to prevent it, however, like I said, the water ingress does not pose a functional problem for the units. They will still operate as intended without any issue.

 

Well thats what I was talking about. I have another question, the new piston design WGA for evo 9, have you finally finish the production on them? Because last thing I heard of them, they were few beta units that TTP was selling?

 

I am positive that it will cause a functional problem once the spring becomes corroded to the point that it affects the resiliency of the spring. This is the case with my unit and now I will need a new spring. Nothing else changed on my car when I began to have problems with the boost. Once I installed the stock actuator back on the car I was able to attain a higher boost value. At this point the stock wastegate was performing better than the Forge unit with the corroded spring.
One questoin that I do have is what type of metal is the spring made out of? If you would like I can send my spring back to you to aid in your research and development on this product.
