TS-0705-1001 - Exhaust Manifold Pressure DampenerUpdated 9 days ago

Important Notes on Your Exhaust Manifold Pressure Dampener

• Turbosmart accepts no responsibility whatsoever for incorrect installation of this product which is potentially hazardous and can cause serious engine damage or personal injury.
• The internal filter should be inspected once a year.
• Ensure that all plumbing is appropriately secured.
• Your exhaust manifold pressure dampener should be mounted at least 100mm from any significant heat source.
• Exhaust Gas are extremely hot and will impact the life of the sensor being used to measure it. The sensor should be remote mounted as such enough surface area of the remote pipe has sufficiently cooled the exhaust gas.
• Sensor port is 1/8” NPT.

Recommendations

• Turbosmart recommends that an appropriately qualified technician fits your exhaust manifold pressure dampener.
• Filter replacement part is TS-0801-3001 as well as necessary O-rings

How to Install Your Exhaust Manifold Pressure Dampener

Kit Contents

Please check that the following items have been provided in your Exhaust manifold pressure dampener kit.

Tools Required

1. Non- marking spanners to tighten fittings

Fitting Your Exhaust Manifold Pressure Sensor

Locate a suitable location for exhaust manifold pressure sensor mounting location

It is common practice to locate your exhaust manifold back pressure sensor in the exhaust manifold pre turbocharger, generally in an area such as the collector to get an average pressure. This will give readings on how much back pressure is being generated to drive the turbine of the turbocharger. However, the exhaust manifold pressure sensor can be used anywhere along the exhaust for pressure readings.

Common mounting locations would be mounted on the firewall with associated bracket. TS-0801-3002.

It is also suggested to ensure the sensor is upright as to not allow any condensation or moisture to collect near the sensor, higher up in the engine bay should also assist. 

Note: Ensure engine has cooled down before conducting any work. 

Fit Sensor 

Before mounting the Exhaust Manifold Pressure Dampener, install a 1/8” NPT sensor. Apply thread lubricant and screw in clockwise until finger tight, then tighten further 1-2 turns for seal.

Exhaust Gas Pressure Feed Plumbing

Routing the exhaust gas to the sensor can be done a couple of ways, it's good practice to ensure that sufficient length is used and a material such as a hard line allow for good thermal conductivity to take hot exhaust gas temperature away from the gas and allow the temperature to cool enough that a sensor can last without an earlier than expected failure. 

An example below shows exhaust gas been run through a coiled hard line of length of at least half a meter allowing for sufficient cooling and remote mounting of the sensor. 

Generally speaking cooling a 1200 degC down with Stainless Steel line will require a minimum of 300mm of coiled hose. To correctly dissipate the exhaust gas temperature.  

Start engine and check for leaks

 Congratulations, your  Exhaust Manifold Pressure Dampener is installed and ready for use. Double check all fittings, lines and mountings then proceed to start engine and check for leaks. No adjustment is required.

WARNING!

CAUTION! If exhaust leaks are present – switch off engine immediately and rectify leaks.

Filter Internal Maintenance 

The filter can be cleaned out as required. To do this, we need two non-marking 9/16” Spanners to disassemble with anticlockwise rotation. The Filter can then be accessed for cleaning. Use a combination of compressed air and elastomer safe degreasers spraying through from sensor side to dislodge particles on the inlet side of the filter.

The Dampener must be torqued to 12Nm (8.8.lb.ft.)

The filter should be refitted in the same orientation. The Clean side should always face the exhaust manifold. 

 Replacement Filter 

Troubleshooting 

• Exhaust Manifold Pressure Dampener leaking – Check fittings are tight and o-rings are present or not damaged.
• Failing the above, submit a technical request to [email protected] with information of your engine, oil type and photos of installation
