OVS determined after testing that the Tail turbine housing and external
wastegate spools faster and makes more power than the Garrett internal
wastegate turbine housing . Comparing the two designs you would have to
run 3lbs higher boost on the Garrett internal wastegate design to make
the same power as the Tial turbine housing with the external wastegate. OVS industry first exhaust link that lets the external
wastegate do it's job without interrupting the exhaust flow. This is
done by taking the exhaust equally from the perimeter between the pipe
and turbine housing so the exhaust stream has the least amount of
interruption into the Tial turbine housing as possible. If you are
looking for the best upgrade for your Garrett turbo kit this is the one.
The OVS Tial upgrade kit was designed and manufactured with the
highest quality parts. This upgrade kit includes, Tial stainless steel turbine housing, Tial 38mm external wastegate, OVS exhaust link, muffler and all hardware to install the upgrade.
