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. :smile
i dont think these are gonna be much more than the 38’s just a little bit more for hardware. maybe 25 more from what they told me earlier this year. they are great for fabrication because they are much smaller and can fit in tighter areas.
