That's crazy! I even went back and looked at your build thread to see the placement of the WG's, and everything looks good to me... Are the WG on a 90 off of the exhaust manifold or a 45? I couldn't really tell.

It looks to me like they're on a straight 90, after the bend up to the turbo... Maybe if they were placed coming straight off the bend it would be better for releasing the exhaust gas/flow? That's the only thing i can think of... The WG's are definitely big enough.

 

 

After seeing that pic, it looks like it should be golden! I honestly have no clue what else it could be though... But I know that going from 7lb springs to 3lb springs, you should not be seeing the same amount of boost! It seems like to me if you took the WG's off you would still see it climb to 7lbs!

Man that thing is gonna be fun to drive!

 

Yea I think I should take the gates off just to check them out to weight out all options

 

That's what I would do, and if boost still climbs... It's gotta be the WG tube/flange placement.

 

Yea but where would I move it to I mean can't really get to much more in the line of flow.

 

That's not necessarily true.

The boost curve will be different, however, the peak boost may be the same. For example, in my setup in 1st gear at the track I see very similar boost (~16-17 psi) on my light spring and heavy spring. Boost in 2nd and 3rd is very different between the two.

If the boost cannot be controlled with springs, need larger wastegate.

 

All the latest pulls have been in third to not break the tires loose.

 

Shouldn't a 45mm WG be sufficient for half the motor?

And taking the WG's completely off to see what it does should be a good starting point to see where the problem is right?

 

What is the A/R size on the turbine/exhaust housings on your turbos?
