Ok so i know there's the boost solenoid and the waste gate, but it seems like there's something else restricting boost, other than the size of the turbo itself. I've found that my ea82t usually boosts 10psi with the wastegate unplugged and the boost solenoid gone (boost solenoid fell and melted the connector so had to junk it) but it is now currently only boosting about 4psi, I'm assuming i have a boost leak somewhere. It runs and drives fine in low RPM's and just is a dog in upper RPM's when there's supposed to be boost and there's only 4 psi.

 

Is there anything else that somehow limits boost? I'm running a TMIC right now. I'm thinking about takeing it off for now and seeing if that makes a difference.

 

btw i was trying to blow the motor up when i did that, but now i just am curious as to why it would boost max 10psi.

Exhaust leak before the turbine would limit boost. Turbo going south (bearing) wouldn't help either. A leak in the wastegate flapper could cause too much exhaust bypassing the turbine.....

 

10psi is about the safe limit of the stock EA82T. The VF7 blows too hot much above that.
