GFB EX50-50MM V BAND EXTERNAL WASTEGATE
Type: WASTEGATES
Vendor: GFB
Description:
The GFB EX50 features not only a huge flow capacity, but also a compact size that is unmatched by competitors for a 50mm 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 Ð much stronger & harder than 6061 Flow tests show that for the same valve lift, the EX50 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 (base flange is compatible with TiAl 44 flange when used with GFB adaptor) Our main goal for the EX50 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.Other fine products
