Boost controller

[johnnie5]

Half a face? Usually its divided up into thirds, approx One third vacuum, two thirds boost.

actually the autometer guage i have




their boost only is 0-35 same as the above but without the vac portion so full deflection but we dont need 35psi

other manufacturers i have seen a 0-20 which would be ideal

What boost are you running, me as well as quite a few on here are running 23 -24 PSI of boost, making the one you show useless. You can see mine on the previous page. 0-30 boost in 5 PSI increments, the Vacuum 0-30 in 10 PSI increments.

So do you see vacume when the throttle is closed....

Myself? only of less the 0.3 PSI

Would a scangauge be good enough to make boost pressure adjustments , or is it best to use anormal style gauge.. Is the scangauge reading accurate

[amalinze]

i myself have never used the scan gauge for this, i have one on my GReddy PRofec Boost controller that goes down to 0.1 of a PSI and an analogue one. My opinion is not to do it until you have a decent gauge though. AND DONT wind it over 17PSI with out a chip or DMS. Apparently hicko found out that the power evens out as there is no more fuel being added for the increase in air which in turn causes high EGT and melted pistons or something....
