GFB EX38 38mm External V Band Wastegate

7003



Designed to cope with the brutal conditions of extreme exhaust temperatures, the EX38 features not only a huge flow capacity, but also a compact size that is unmatched by competitors for a 38mm wastegate.

  • Supplied with a 13psi spring
  • 7psi and 9psi springs also available that can be ganged together with the supplied 13psi spring in various combinations to allow boost pressures of 7, 9, 13, 16, 20, 22 and 29psi.
  • Body, valve and seat are made from high-temp stainless steel
  • Actuator housing machined from billet 7075 aluminium – much stronger & harder than 6061
  • Flow tests show that for the same valve lift, the EX38 outflows its nearest competitor by 18%
  • Internal valve shroud protects valve stem from excessive heat and prevents carbon-related sticking
  • Top-hat style Nomex-reinforced silicone rolling diaphragm for longer valve travel
  • 90° banjo-style boost hose connectors
  • V-band clamp mounting system, supplied with 304 stainless weld-on adaptors

Our main goal for the EX38 was to create a wastegate that had a very large flow capacity in a package that is physically as small as possible.  This was achieved with the use of CAD design which allowed us to minimise the amount of unnecessary bulk (particularly on the actuator).

Good flow around a poppet-style valve depends on a smooth and generous bowl area into which the valve lifts.  Many brands do not allow enough room around the valve head for good flow, instead relying on increasing the valve travel as a band-aid solution.
