I read your post twice, and I still am not sure I know what your talking about.. Maybe it is the terms you are using that I may not be familiar with? Most of the turbo systems I have seen use a "waste gate". As I understand it, The waste gate controls the flow of exhaust gas between the turbo fan and a bypass pipe (a pipe that lets the exhaust bypass the turbo). The boost (pressure) on the exit of the turbo (going to the intake) controls the position of the waste gate. By adjusting the mechanical linkage from the diaphram to the waste gate, you essentialy set at what level of boost pressure the gate opens. When the gate opens, the additional exhaust gas is "wasted", and will bypass the turbo. The end result is the turbo will not spin any faster. Modern systems use an electronic control with a variable (computer controled) waste gate. This allows you to regulate the boost based on other engine data. BTW, those expensive "monster cables" *DO* make a difference. --- Martin Gutkowski <webmaster@xxxxxxxxxxxxxx> wrote: > Hi All > > I would like some input on something that I want to > learn about before > installing my Z7U turbo PRV in my DeLorean. <SNIP> __________________________________ Do you Yahoo!?
