legacy b4 boost

Hi lads, anyone know wat boost d legacy b4's are?? Eli, if u read this, am I right on saying that my legacy is 1 bar on d first turbo and 1.2 on d second?
:ponder2:
 
Yeah mate, the boost on your Legacy is up as it was mapped to run higher boost on both turbos.
 
is there different ways to measure this? mine boosts just over 0.8 and 1.5-1.6, not sure if its psi?
 
That would be BAR Jay from the figures you quoted. 1.5 and 1.6 BAR seems high even for a mapped B4.

1 BAR = 14.5 PSI
 
right ya thats what davesti said a bit back. that must be why i get fuel cut pushing it up hill. like hitting a brick wall but going through it. done my clutch in in a year ( prob cause of messing in the snow too though) but the speed is incredible.anything i can do without another remap

Mine was mapped for 1.5bar peak, it really depends on the individual car's capability :thumbsup:

Thats OK on your Impreza Robbie but that boost too much on the B4 turbos.

I was talking about my B4 which bob mapped :thumbsup: ... Ran perfect for over 2 and a half years and I liked to make good use of that 1.5bar :icon_grin:
 
standard for the B4s are

.8 and 1.0 for manuals
.7 and .9 for autos!

thats factory figures anyway

anything over 1.2 secondary on a standard map is bad news
