BOOST
Boost is
power!! - The more, the cooler, the faster, the BETTER !!!
Well maybe for some of us anyway. Myself for
sure, but for some, the factory allocated portion is enough. Even these
people need to consider the turbo boost controller or "WASTE GATE CONTROL
CANISTER" .
This is the small round can that is attached to the turbo housing with the
metal arm stretching across the side to the Exhaust snail. It usually has a
small hose joining it to the front of the turbo compressor snail outlet.
This is so the boost pressure can cause the waste gate to be actuated by the
compressed air to open a small valve in the exhaust snail to by-pass some of
the exhaust gas pressure to the exhaust pipe after the turbo. ( See
illustration )
When the by-pass valve opens and lets some of the gasses escape to the
exhaust, the turbine shaft slows down and this reduces the compressing
action or boost.
TURBO BOOST TIPS
The spring in the wastegate canister will loose pressure after time allowing
boost to take more time to build up as exhaust gas is leaking past the
by-passing valve.
If the boost sensing hose to the canister is leaking, boost will go too high
and detonation or fuel cut-out will occur. ( in Mits. STARIONS & CORDIAS
anyway, others may be similar.) Indecently, this is how we modify the
factory boost setting, but caution must be exercised as many factors must be
considered before doing this.
Detonation is to be
avoided at any cost. |
