Wastegates Traditional Application vs The Hlava Sequential Turbo Manifold

The designed intent behind the Hlava Sequential is to maximize performance with synchronized efficiency. It may seem contradictory to many others when they see claims of eliminating the use of a wastegate in a turbocharged system. Let alone that it can be a more efficient system than the traditional setups. This is due to the fact that most people have just been accustomed to the more traditional setups that heavily rely on the usage of these components and are unaware of how inefficient they truly are. Even though there are some downfalls to using a wastegated system, there are some benefits to both utilizing and not utilizing a wastegate on the Hlava Sequential Turbo Manifold.

               First, we’ll talk about the Hlava Sequential Turbo Manifold using a wastegate. When utilizing a wastegate with this apparatus, you gain the ability to program a target boost level. But if you are intending to utilize the Hlava Sequential Turbo Manifold in its designed manor, a wastegate can be implemented as a fail-safe if you are not completely confident in your choice of turbocharger and its capabilities to utilize all the exhaust gas your engine is able to supply it with. There are some issues that will come with the implementation of a wastegate. When setting a target boost level, this may eliminate the turbocharger’s ability to create efficient output in high load/high rev conditions, similar to what is experienced with more traditional setups because the ecu (in accordance with its programming) will do what is programmed to force your turbocharger to create the predetermined level of boost. Even if that means forcing the turbochargers to work on inefficient areas of their maps and rotating faster than it was reliably meant to. This will likely lead to elevated intake temperatures which means a less-than-optimal quality of air delivered because higher temperatures mean less usable energy in the air. This can also lead to excessive exhaust manifold pressures relative to boost output placing excessive strain on engine and turbo components alike. When utilizing a wastegate and setting a target boost level, this also increases the amount of cost as you will need to spend more on the added components as well as making the tuning process a lot more complicated.

               Now, utilizing the Hlava Sequential Turbo Manifold in the way it was fully meant to be applied, there is no need to use a wastegate or boost controller because of the efficiency approach. When following the parameters that meet the 100% efficient approach, the large turbocharger can utilize every bit of exhaust gas the applied engine can provide it with. This means there is no need for a wastegate which also simplifies the tuning process as the wastegate adds to components that must be coordinated with the rest of the programmed setup. Also, when eliminating the need of a wastegate and boost controller, the Hlava Sequential Turbo Manifold not only allows the turbochargers to function in the most purely mechanical sense they can operate in, but this allows them to function in areas of their maps that are both efficient and effective. Because they will only function efficiently, this means they will be able to supply colder intake temperatures which means the air delivered is much more efficient and effective. Moreover, this means the air has more usable energy relative to the quality seen by more traditional setups and the insurance of efficient and effective usage can translate to more longevity out of both turbochargers and engine components. With this approach, there is no need to sacrifice on the performance side of things as, if properly paired turbos are applied, the engine will experience an increased range of the RPM where it receives effective turbocharger response. By pairing the turbochargers well, you will see better acceleration because of the much-improved earlier RPM turbo response that meets in the middle of the RPM band with a turbocharger that is able to utilize all of the exhaust gas that your engine will be able to supply it with and not need a wastegate. Being able to utilize every bit of exhaust gas that your engine is able to provide also translates to a more complete burn meaning less emissions.

               Having learned the advantages of utilizing the Hlava Sequential Turbo Manifold, both with and without the implementation of a wastegate, the real takeaway is that whatever path is chosen, the right initial path chosen is using this apparatus anyways. There are benefits to utilizing this system either way it is approached.
