Complete Steer to Deleting the EBPV on a 7.3L Power Stroke
Applicable Models:
1994.5 - 1997 Ford F-250, F-350, F-Comprehensive Tariff
1999 - 2003 Ford F-250, F-350, F-450, F-550 Super Obligation
Relevant Engine(s):
7.3L Big businessman Stroke (Dot)
Reducing pumping losses some in and unconscious of an engine increases its efficiency and may improve carrying into action, as is the event in deleting the exhaust backpressure valve from a 7.3L Power CVA. While the valve's orbit appears comparatively small when IT rests in the open pose, numerous accounts suggest that an EBPV edit will lower EGTs and improve turbocharger response crosswise the board.
7.3L Top executive Stroke EBPV Operation
The wipe out backpressure valve is a simple twist configured to reduce the time required for an railway locomotive to reach operating temperature past restricting run through flow and essentially simulating a load happening the engine. The valve itself is a simple butterfly type that is mounted to the turbine outlet of the turbocharger. The EBPV is connected to the EBPV actuator by means of a simple gene linkage. The actuator features a plunger/piston that moves forwards and backwards to control the position of the EBPV. A EBPV regulator/solenoid controls the flow of locomotive engine oil into the actuator, which successively controls its range of motion. The EBP sensing element located at the front of the HPOP source is victimised to discover the correct position of the EBPV during the warmly rising process. Once the engine approaches operating temperature, the system is injured and the EBP valve is stored in the give position.
EBPV Delete Considerations
One and only could argue that this system was developed with the spirit of reducing emissions since a diesel motor does not reach peak combustion efficiency until it reaches operating temperature. A subsequent benefit of diminished fresh up times is less fuel dilution, as a cold engine at idle is by far one of the almost profound conditions in which fire dilution occurs. Regardless, IT is a restriction in the path of the exhaust stream exiting the turbine trapping and therefore imposes a negative effect on engine performance and turbocharger efficiency. There are many reasons why some choose to delete the EBPV, including:
• Negative event along engine performance and turbocharger efficiency (removing EBPV reduces turbocharger lag and improves performance characteristics).
• Creates higher tucker out gas temperatures (EGT), especially with the improver of performance enhancing aftermarket equipment.
• The EBPV governor and actuator are unerect to leaking engine oil at the bum of the turbocharger; they are non easily accessible and only serviceable with the turbocharger removed.
• The EBPV regulator and actuator are expensive to rebuild/restore.
The two negatives regarding deleting or disabling the EBPV are 1) the engine will require Thomas More clip to reach operating temperature. This is non a major business in areas with warmer climates, however this could throw negative impacts along engines that are started in extremely cold environments where fire dilution is already Major headache. 2) the locomotive engine will bring forth greater emissions relative to the difference in metre necessary for an engine to reach operating temperature with the EBPV vs without it. This is unlikely a unplayful issue for all but, however the EBPV is an emissions insure device and hence IT is compulsory to be amply useable during emission tests in regions where they are compulsory.
EBPV Blue-pencil Options
The "correct", or might I suggest "most exhaustive" method acting of deleting the EBPV is to purchase a non-EBPV turbocharger pedestal and a non-EBPV turbine outlet. Some of these are manufactured by Garrett, the OEM turbocharger manufacturer for all 7.3L Mightiness Stroke diesels. The part numbers game for these components are as follows:
• 1994.5 - 1999 (early) non-EBPV turbine outlet: Garrett 448179-0005
• 1994.5 - 1999 (early) non-EBPV turbocharger pedestal: Garrett 448486-0004
• 1999.5 (former) - 2003 non-EBPV turbine electric outlet: Garrett 451274-0005
• 1999.5 (late) - 2003 non-EBPV turbocharger pedestal: Garrett 702670-0002
A second base, and very inexpensive option is to simply polish of the valve, catgut it, and disconnect the EBP regulator. Remove the butterfly valve, plug the holes with freeze plugs or a similar piece of common hardware, and reinstall it. Disconnecting the governor keeps the piston on the actuator in the retracted position. The problems with this method acting are that 1) it testament throw a soft DTC and 2) the actuator and regulator can even so develop an oil leak in time. Simply unplugging the EBPV in club to hinder its mental process negates to achieve the obvious benefits from removing the restriction and therefore is a ineffectual approach.
A third option is to remove the EBPV (instructions below) and replace IT with a not-EBPV turbine exit while safekeeping the factory EBPV turbocharger pedestal. This option eliminates the limitation, however information technology reduces the cost by avoiding the expense of purchasing a new turbo pedestal and all the items required to reinstall the turbocharger. Erstwhile again, the actuator and regulator could possibly leak in the future.
EBPV 470 Ohm Resistor Modern
To disable the EBPV electronically without deleting any of the pedestal components, you can simply unplug the two prong connector mounted on the compressor housing near the compressor recess. However, the PCM bequeath realize that the system is not functioning and trigger a DTC. Our 7.3L Power Stroke EBPV connecter plug away will clear this problem, or you can jump the two prong connector happening the harness side with a 470 Ω, 1 Watt resistor and mag tape/heat shrink it securely. The PCM testament read that the EBPV system is functioning in good order even though the connector is unplugged.
EBPV Remotion Procedures
Note - EBPV delete performed on 1994.5 - 1999 7.3L Power Stroke railway locomotive. Concept is correspondent for later 1999.5 - 2003 model year engines, yet the cognitive operation wish birth somewhat different steps.
Pawl some thumbnail to view fullsize, elaborate mental image
• Disconnect the actuator gene linkage from the EBPV by sliding the latch/arm on the rod towards the actuator (driver side), then pull downwards.
• Hit the three bolts connecting the EBPV to the turbocharger turbine housing using an 8 mm 12 point socket. These bolts will be tight and you may want to hit them with a sharp fluid (PB Blaster, WD-40, etc) before attempting to loosen them.
• The EBPV regulator electrical connector is located just infra the compressor recess at the straw man of the turbocharger (refer to image).
• Installation of the various EBPV delete techniques/products is reversal of remotion.
• With the EBPV placed on a bench in the "open" position, the residual exhaust restriction is clear visible.
