t3's, t3/4's etc

[Wow, you got 23 psi boost from a K26 turbo with stock
CIS if I understand correctly ?? This is contrary to
what I heard from previous posts to the list that
suggest 16-18 psi is the max limit for a turbo CIS
setup due to fuel and especially airflow limitations.
Is there something that you did not mention in your
setup that allowed these high boost levels with the
K26 ??

Ed,

I've seen 25+ PSI - blowing the intercooler end cap off - before dialing
back on my schrapnel knob and strapping the intercooler. A safe limit for
the setup is around 15 psi ( I know I've said 18 before, but hot weather and
heat soak is suggesting a more conservative setting).  I don't think the
stock turbo has a problem of delivering the boost, but the turbo starts to
lose efficiency and longevity at higher levels, and the stock fuel injection
will not deliver sufficiently.
