TiAL will be replacing the F38 wastegate with the new MV-S wastegate.
"Small was on our mind when we developed this new ultra compact wastegate. It stands only 3.7" in height vs the current F38 which is 4.85" Other features include 3 bottom pressure ports for easy install and a top mount pressure port that can be rotated 6 different ways. No more bolts or gaskets and all configurations are leaded fuel safe. We also altered the way the diaphragm sits so it is virtually impossible to pinch. A late fall release date is scheduled."
The new wastegate will be sold with all part included, that means flanges, clamps, air fittings, springs and all!
Currently the TiAL MV-S wastegates are sold standard in silver with a 1.0 bar spring pressure and include the remaining springs, please see the following charge for spring size identification.
In the near future, TiAL will be assembling these wastegates with
NO spring inside and all the springs will be included for you to select
your own pressure and install. (Updated 06/07/2011) Other colors are available by special order. Please call for details, 972-984-1800.
