What is an acceptable level of boost pressure drop between the turbo and plenum ?
400 BHP - 650 KG\'s = 616 BHP Per Ton of Rotary Power

That\'s the way to do it! :Thumbsup!

There is no such thing as an acceptable loss, it should be made as small as possible within the given constraints.

How much are you getting Tony ?

on average between 1 to 2 psi drop, anything more throw it in the bin

so 3 - 4 psi is probably too much then?
400 BHP - 650 KG\'s = 616 BHP Per Ton of Rotary Power

Depends at how much boost you\'re losing 3-4 psi.

As Mike say\'s it very much depends on what boost you are running.
But 2 psi drop is fairly normal at at that sort of boost level.
Some people set up boost controllers and guages to read before the intercooler,but we prefer to set them up after,that way everything is setup for what the engine is actually receiving.
