Hi
Paul,
I'll
be interested in the answers to this question myself. It was my understanding
that a pop-off valve and a waste gate were the best way. I DID learn something
interesting the other day thought....
On my
91 turbo there is a vacuum pipe which comes out of the waste gate and goes to
the side of the turbo casing. It has a T for another vacuum hose connection
which goes to a solenoid in the stock installation. The engine guy tells me that
if this vacuum hose is open to the ambiant pressure, then the wastegate will be
open. If it's blocked, then the wastegate will close. All I have to do to
control the wastegate is fit a valve to this hose.
I
wonder what Rusty and Todd are doing in this area.
Regards,
John Slade

wastegate requirements
Hi, fellow canardians. I am still sitting
on that fence between turbo or not to turbo. (I have some splinters in my butt
cheeks from that fence). I was reading the installation and
operation manual that came with my MicroTech electronic engine management
system, and under "setting up" there is a section entitled BstCUT, which
says "This feature prevents turbo engines from overboosting by cutting all
fuel supply when bost pressure exceeds the limit set in theBSTcut screen,
i.e: if you set this value to 10 psi, all fuel supply will be
immediately shut off when boost is 11 psi or higher." Does this sound
like a useful tool in installing and setting up a turbo on my 13b?
Please don't flame me, as I know less about turbos than I know about
understanding women. Does this mean I would not need a wastegate?
Thanks in advance for your replies. Paul Conner, Mobile,
