Question about Turbo wastegate actuator plumbing


Recommended Posts

Hi,

I have a question about where the wastegate actuator plumbing is taken from,

The picture here has 2 connections, A and B,

I have seen turbos with either A or B, what is the difference from taken the "pressure" from A over B,

Why is A and B joined at C ?, what does this do ?

From what I can remember, running it off ports a & b is supposed to provide a more accurate boost source, the pressures at port a and b port will be different to each other by a little bit, but to be honest I don't think it really matters, I normally just run it off port a or off the inlet manifold.

I don't think I've ever seen them joined together.

 

I've used either "A" or the intake manifold to reference boost pressure.

 

Sourcing at the turbo is said to protect the turbo from overspool, due to reacting quicker and using what is at the compressor nozzle, since this is usually a little higher in pressure than what is at the manifold.
