Quick Answer: What does a fuel plate do?

Cam plates, or fuel plates, are an effective method to increase fueling to your 12 valve in order to improve the overall performance by controlling the rack travel of the pump itself. Different cam plates on various pumps will delivery varying horsepower levels.

How do you take the fuel plate off a 12 valve Cummins?

Fuel plate modification p-pump Cummins

What does removing the fuel plate do?

Removing the plate is a bad idea, you risk damage to the pump and a runaway motor. Run a 0 or 100. Get the springs with the 4kGSK, anything over 3400rpm needs them. The GSK kit allows full fuel flow through the rpm range, rather than defueling at about 2600.

What does fuel plate do in P7100?

Commonly known as a “cam plate”, BD’s Fuel Stop Plate controls the rack travel, which affects the amount of fuel the Bosch P7100 fuel pump delivers. Six different ramp designs enable power gains from 30 to 150 hp and 70 to 300 lb. -ft. of torque.

How much HP does a 12 valve Cummins have?

The Cummins 5.9-liter 6BT 12 valve has 230 HP, 440 lb-ft of torque, and a P7100 inline injection pump right out of the box. The 12-valve is also a popular engine swap choice, powering a slew of Jeep, rat rod, muscle car, and dragster projects.

What does a boost elbow do?

Product Details. The installation of the brass elbow permits turbo boost pressures of greater than 20 psi without the waste gate opening. This goes in the waste gate feed line on the turbo, which is located on the face of the turbo.

How do I turn up the fuel on my P pump?

By sliding the AFC housing forward (toward the front of the pump) and backing out the pre-boost screw (on the backside of the AFC housing), fueling can be brought in at a much lower rpm, the governor linkage is altered and the rack is adjusted forward.

How do I get rid of AFC housing?

Take the AFC to a suitable working location (work bench). Remove AFC cover by removing (3) flat-standard screws and grinding a slot in (1) tamper- proof screw and then removing screw. Also grind a slot in the tamper-proof screw on the small pre-boost fuel cover and remove the cover.

What is a 12v Cummins?

The 12-valve Cummins, officially the Cummins 6BT, is the engine at the bottom of the family tree of diesel engines (at least in pickup trucks). Its simple, straightforward design is a symbol of reliability, solid engineering and tractor-style torque.

Can you put AP pump on a 24 valve Cummins?

While not everyone is looking to build a twin-turbo, P-pumped, sled pulling monster, the same basic parts used in this swap can be fitted to any 24-valve truck.

How do you turn on the star wheel on a Cummins?

Registered. top of the star wheel goes toward the engine, so counter clockwise if your standing in front of the truck.

Which year 12 valve Cummins is best?

1996-1998 has the best injection pumps (perhaps ignoring the 1989-1993 VE) and stronger automatics compared to earlier years. Look at the buyers guide section in the thread below. The 1998 12 valve trucks were only built in 1997.

How much power can a stock 12v Cummins handle?

The forged-steel connecting rods found in the 12-valve 5.9L (and ‘98.5-’02 24-valve engines) are of an I-beam design and capable of easily handling 800 rwhp in stock form.

Why is the 12v Cummins so reliable?

The Cummins 12v/6BT is widely regarded as the best and most reliable diesel engine ever produced. These engines are extremely simplistic, operating with mostly mechanical components rather than complicated electronic ones. The simplicity allows for massive power potential in conjunction with ultimate reliability.

How much boost does a 5.9 Cummins make?

On 1998.5-2004 5.9L Cummins you will need to physically modify your wastegate to gain more turbo boost. Doing this without the Boost Fooler will result in check engine lights and codes set into the computer. Stock 98-04 trucks should generate 18-23psi of boost pressure stock (depending on year model).

How does a boost elbow work on a Cummins?

The Actuator has a mechanical Spring in it that once the preset pressure is reached from the air the lever moves and opens the wastegate dumping exhaust gas that drives the turbo (boost).

What does a boost fooler do Cummins?

The Boost Fooler will allow you to increase turbo boost to compensate for the added fueling modifications you have made. Enabling your turbo to produce more boost will increase overall horsepower and torque and lower your exhaust temperatures.

What will 4k governor springs do for my 12v Cummins?

The Industrial Injection 4000 Governor Spring Kit is by far the best modification you will ever do to your 12 valve Cummins engine. The factory governor generally will slowly start to defuel the engine around 2300-2400 rpm and drastically decrease performance and pulling power.

How do you set the timing on a 12 valve Cummins?

Power Driven Diesel Timing Kit Instructions

What is a diesel P pump?

A mechanical diesel injection pump is designed to pressurize, meter, and distribute the diesel fuel that’s injected into the engine to create the optimum power output.

Is AFC live worth?

AFC Live is a nice piece, and can save you some time tuning. But, if your budget is tight, it’s not really needed for most builds. One simple/cheap mod that has a similar effect, is to just add a boost elbow or boost control valve in place of the original air fitting on the AFC.

Is 12 valve or 24 valve Cummins better?

12v vs 24v Tuning &amp
Aftermarket Potential

When it comes to serious power and performance the 12v 5.9 Cummins takes the win. These engines are known to hold up better at extreme power levels when compared to the 24v engines. P7100 injection pumps on the 6BT are easier to mod and support the extra power.

Does a 12V Cummins have a lift pump?

The 12 valve Cummins features a cam lobe which activates the plunger on the lift pump (see photo).
