GFB Wastegates - 38mm, 44mm & 50mm V-Band Wastegate - GFB EX38, EX44 & EX50

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

Supplied with a 10psi spring, 5psi & 7psi springs are available & can be ganged together in various combinations to allow boost pressures of 5psi, 7psi, 10psi, 12psi, 15psi, 17psi and 22psi. This is the largest range of boost pressures off-the-shelf.

Body, valve and seat are made from high-temp stainless steel.

- Actuator housing machined from billet 7075 aluminium - much stronger & harder than 6061

- 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

- Brass boost hose connectors

- V-band clamp mounting system, supplied with 304 stainless weld-on adaptors (base flange is compatible with TiAL 38 flange)

- Quality & Performance unsurpassed

The GFB 44mm Wastegate has been designed to cope with the brutal conditions of extreme exhaust temperatures, the EX44 Wastegate features not only a huge flow capacity, but also a compact size that is unmatched by competitors for a 44mm wastegate.

Supplied with a 5psi & 10psi Spring already fitted , a 7psi spring is available & can be ganged together in various combinations to allow boost pressures of 5psi, 7psi, 10psi, 12psi, 15psi, 17psi and 22psi. This is the largest range of boost pressures off-the-shelf.
