Overview
Show original supplier description
Part #: 7301
Massive Performance, Compact Size.a Industry-first diaphragm design - the WGAa (TM)s Silicone/Nomex diaphragm uses a new bead retention design that achieves the largest effective area with the smallest possible outside diameter. This keeps the overall size of the WGA down whilst giving it more control authority over the wastegate flap, resulting in better boost control. Ita (TM)s like telling your turbo what to do instead of pleading with it!a Longest stroke a with 18mm of rod travel, the WGA is suitable for controlling the largest of internal wastegates, or the extra travel can be used to further increase boost pressure without having to change springs.a Unique pivoting rod guide a machined from PEEK (an extremely high-performance engineering polymer), the encapsulated spherical rod guide takes up significantly less height in the actuator body than other designs, whilst offering low friction and superior wear resistance.a No unnecessary bulk a sounds obvious, but attention to detail in the design means the WGA is the shortest actuator on the market.More Adjustable, More Easily. Setting the base spring pressure correctly for your application can have significant performance benefits, so we made sure the WGA offers the best adjustability on the market!We supply 3 stainless steel springs that can be used in any combination ranging from 5psi to 22psi, but thata (TM)s only the beginning. Whilst other brands may offer more spring options (sold separately), changing springs to fine-tune boost pressure is time consuming and quite frankly, a pain. Thata (TM)s why we added another industry first - turnbuckle adjustment. The long stroke of the WGA means more adjustment range for the spring pre-load, so you can fine-tune your base boost pressure in a matter of minutes without swapping springs or removing the actuator. Available in bolt-on or universal kits - Check the GFB website for details.
Bolt on high performance internal wastegate actuator. The WGA replaces the factory turboa (TM)s actuator, offering a larger diaphragm and adjustable base spring pressures ranging from 5-22psi to get the most out of your turbo.
