Wastegate Manufactures @ StrikeEngine.com - External Wastegates

Greddy
One of the most important components in a well designed turbocharged engine set-up, is a properly sized wastegate. Too small of a wastegate can cause boost creep while too large of a wastegate will increase boost lag and decrease performance. Our GReddy external wastegates are made from the highest quality materials to insure both stability and durability in a turbocharger's boost control. Each unit is adjustable as well as rebuildable. Available in 4 sizes and various spring rates. From 0.8kg/cm2 (11psi) to 1.5kg/cm2 (21psi) and up.

HKS
HKS external wastegates are race proven units that offer unsurpassed craftsmanship, reliability and functionality for a diverse range of applications. Each HKS wastegate is constructed with a stainless steel valve, a die-cast mount base and valve seat, a fully sealed shaft and a high temperature resistant diaphragm. Available in three different types, Standard, Racing, and GT, HKS has the appropriate wastegate for every application and performance level. The Standard Wastegate utilizes a 40mm valve and is rated to applications producing upwards of 500 horsepower. The Racing Wastegate utilizes a 50mm valve and supports up to 1000 horsepower. The GT Wastegate is the largest of the series and utilizes a 60mm valve to support applications producing well over 1000 horsepower. Each wastegate type offers several different spring rates for various boost pressure levels. Also available are universal base flanges, flexible outlet tubes, barb fittings and gaskets for custom applications.

Synapse Engineering
The Synchronic actuator consists of four varying-sized surface areas inside, not two equal ones like conventional wastegates have. As boost pressure is applied to a surface area, a force is applied and the spring compresses, thus lifting the valve. The Synchronic wastegate's varying surface areas and ports make for a number of different boost combinations that can be applied without the need for a controller. All that's required is splicing the lines together and routing them to a pressure source on the engine. This all controls how far up the valve moves, not just how many pounds of boost the turbo will produce. The conventional wastegate is also different in this respect. Rates can be changed by swapping springs but remain dependent on the amount of preload. Also, as spring rates increase here, and more boost is made, the diaphragm has to stretch more, resulting in a valve that doesn't lift as much and possible boost creep. This all determines when the wastegate will open and just how much boost the engine will see, so it's got to be right.

With the Synchronic wastegate, users can adjust spring preload and spring rate interdependent of one another as well as control how the valve rises, and how high it rises, as boost climbs. This increases response time and wastegate flow characteristics and should be tailored for individual engines.
