Shelby Charger T1 to T2 #1
video # 1 of 6. My 87 shelby charger. Im converting it from t1 to t2 and
will be showing you the way to do it and the parts you'll need.
a wastegate from a Mitsubishi 15g turbo
from a mid 90s Volvo 850 turbo being
tested by a Kent-Moore wastegate tester.
Redneck turbo wastegate actuator BUILD YOUR OWN!
Tune a Wastegate.
Part of the jeep turbo project is the
idea of reliability and a big component of that is low Boost pressures. I could tell I was too high
during the testing and rather than buying a new actuator I have decided to
cut my down. It is a very simple modification project for anyone with a
few tools. Be sure to follow along as I work the kinks out of my turbocharged F head project.

The sole guidance I had found for this part of the project is located here:
lower PSI on a GN wastegate acutator
How to lower PSI on a wastegate w/ out opening it up. This is a factory HD
wastegate from a 87 Buick Grand National set at 18-19 psi. I needed to
lower the PSI to 4-7 PSI.
Knockoff TiAL MVS Tested
Video testing the durability of a knockoff TiAL wastegate, the wastegate
was broken right out of the box (wouldn't hold pressure) and the unit could
not be installed if the valve seat was inserted because of poor machining -
so in truth the wastegate could not have been used on a car at all. The
video is at 8x speed, the video is 47 min long compressed into about 6 min.
the wastegate only lasted a bit over 42 min on the test bench - around

How to change turbo actuator?
The simplest closed-loop control for a wastegate is to supply Boost pressure directly from the charge air
side to the wastegate actuator. A small hose can connect from the turbocharger compressor outlet, charge pipes, or
intake manifold to the nipple on the wastegate actuator. The wastegate will
open further as the Boost pressure
pushes against the force of the spring in the wastegate actuator until
equilibrium is obtained. More intelligent control can be added by
integrating an electronic Boost
Standard wastegates have one port for attaching the Boost control line from the charge air supply
line or Boost control solenoid. This
is the most common configuration and the only type of configuration found
on internal wastegates.
A dual port wastegate adds a second port on the opposite side of the
actuator. Air pressure allowed to enter this second port aids the spring to
push harder in the direction of closing the wastegate. This is exactly the
opposite of the first port. The ability to help the wastegate remain closed
as Boost pressure builds can be
increased. This also adds further complexity to Boost control, requiring more control ports on
the solenoid or possibly a complete second Boost control system with its own separate
solenoid. Use of the second port is not necessary. Secondary ports, unlike
primary ports, cannot be simply attached to a Boost control line and require electronic or
manual control to be useful. C02 can also be used to apply pressure to the
second port, to control Boost on a
much finer level.
A wastegate is a valve that diverts Exhaust gases away from the turbine wheel in a
turbocharged engine system. Diversion of
Exhaust gases regulates the turbine
speed, which in turn regulates the rotating speed of the compressor. The
primary function of the wastegate is to regulate the maximum Boost pressure in turbocharger systems, to protect the engine and
the turbocharger. One advantage of
installing a remote mount wastegate to a free-float (or non-WG) turbo includes allowance for a smaller A/R turbine
housing, resulting in less lag time before the turbo begins to spool and create Boost
Diagnosis of Massive Air Leak at Turbocharger Wastegate Actuator
This video shows the diagnosis of a gross air leak at the diaphragm of the
turbocharger's wastegate actuator on a
customer's 1990 Eagle Talon TSi AWD with 4G63T. This vehicle had been
built by some people that were supposedly known for these vehicles. If so,
they should have caught this easily. The vehicle had also been to one
other shop prior to coming to Street Sports for diagnosis.
