Manual Boost Controller Q

[Inigo Montoya]

So how do you tell what you set your boost too? I hope theres a way besides for hitting WOT and seeing where it peaks at :-/

TYVM for replies

A manual boost controller is placed in the path of the waste-gate’s sensor. The controller bleeds off some of the pressure in the line so that the pressure measured at the waste gate is lower than actual. This tricks the waste gate into staying closed longer than usual so a higher level of boost is reached. They’re really cheap to build, but the most important expense in this project is to getting accurate boost gauge. A little bit of bleed goes a long way and there is no way to tell where you are at without a proper gauge.

ok i understand that.. so my dreaded assumption is correct... the only way to tell what psi it will boost to is drop into neutral and rev tune it? gaaaaaaaaaay

no most controllers will have some way of telling... i know on my buddies... every "click" is 1psi

no
you go in increments. from all the way down and then you turn from there.
btw you cant measure boost in neutral
