Boost and Intercooler?

[30psi]

Pressure drops are common across intercoolers, due to resistance in the intercooler and pipe work.

I see, that makes sense, Is 2psi a lot to drop or not?

This kinda leads me on to my next question which is where should I be reading my bosst pressure from? I just tapped a new guage into the the pipe that the Factory fitted boost guage ran from, but If I'm lossing pressure through the IC then should I read it from the turbo side to make sure I don't over work that?

[30psi]

The actuator should be fed off of the compressor housing of the turbo.

Its probably an average drop for the cheaper type of IC's, but remember that its only a T2 trying to push the air through.

[JackieFan]

The actuator is fed from the compressor housing but is that where I should also read the boost from?

[30psi]

I see what you mean now...

I think it would make more sense to read it at the inlet manifold. That way you can monitor leaks etc.

Wouldn't turn it past 12psi though...

[JackieFan]

Good, that's what I thought and have done

Is 12psi the limit of the stock internals or the T2?

[30psi]

Its kind of the limit of the T2.

I found at 12psi with a volvo intercooler that turning up made no difference, and it struggled to hold the boost at the top end anyway (which is the limit).
