AMF was able to fit this manifold under the hood of a 3000GT VR-4 which doesn’t have very much room to begin with. If you are able to fit two turbochargers, it is likely that you will be able to fit it to your vehicle but just to be sure, here are the dimensions: Height(RED)~ 8.375”, Width(Yellow/ Front of Manifold Body to Back of Bridgepipe)~ 5”, Length(Blue/ Inlet V-band 1 to Inlet V-band 2)~ 12.125”
The actuator spring rating should be relative to an area of the applied primary turbocharger’s turbine MAP’s pressure ratio where it begins to become effective. This ensures localization of an efficiently effective area per its Turbine MAP and can be incrementally adjusted from there if needed.
Absolutely! If you have an engine that is designed to work with forced induction, you can benefit from having the Hlava Sequential Turbo Manifold.
The utilization of a one-way flap/swing valve on the charge piping of the initial response turbo allows the compressor to flow unrestricted and closes once the larger turbocharger’s pressure takes over, ensuring that the pressure from the large turbo is not backing out through the smaller turbocharger’s compressor housing. These valves can be found at various hardware stores such as McMaster Carr. (Be sure the valve is rated accordingly for temperatures and pressure relative to your application)
You can start with a PSI rated spring based on the amount of boost the initial response turbo will likely be around when in it’s predetermined efficiency area of its MAP, and make slight PSI adjustments from there if needed (-/+ 1-2psi). An additional aid in valve operation but likely not be required is running a vacuum line off the intake manifold or large turbo at its pressure port to allow boost pressure to help. Start with a spring setup that is 1-2psi lower than the amount of boost the initial response turbo will likely be around when in it’s predetermined efficiency area of its MAP, and make slight PSI adjustments from there if needed (-/+ 1-2psi). For example, the GT2554R is in an efficient area of it compressor MAP around 11psi, and we found a 10psi spring setup worked best for our application. An additional aid in valve operation but likely not be required is running a vacuum line off the intake manifold or large turbo at its pressure port to allow boost pressure to help.
The dual-valve manifold was designed to be installed on an ICE operated vehicle by utilizing one exhaust bank per inlet on the Hlava Sequential Turbo Manifold or by dividing the cylinders at the end-user’s discretion. Also, this manifold does NOT come with mounting flanges for the turbochargers. This allows the end-user to incorporate the necessary flanges for their choice in turbocharger application.
