TiAL's New F38 wastegate replacement is the new MV-S wastegate.

Small was in their mind when they developed this new ultra compact wastegate.Stands only 3.7" (94mm!!) in height vs the current F38 which is 4.85" (125mm)

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.

Diaphragm is altered to sit in where its virtually impossible to pinch. 

V-Band inlet and outlet make install easy, flanges and clamps are in the box!

Integrated -4 AN water cooling ports that cycle a small amount of coolant through the actuator top to keep the temperatures down in extreme conditions such as road racing. These are leak tested after installation from the factory and can be removed if not utilized.
