i have a t3/t4 turbo setup from drag w. a tial wastgate
the box on the w.gate says .5 as a spring.... i forget off hand which psi this is... im plainning on running 14-19 lbs thru it....
so if anyone knows anything

 

.5 of a bar.

a bar is 14.5

14.5*0.5=7.25psi

you should get a 1.0 bar spring

 

.5 bar spring should be around 7PSI

1 bar = 14.5
