Got a Diesel Question

[Proquad101]

I've got a 2002 F-250 powerstroke with a bullydog chip, straight exhaust and a K&N filter, I was wondering what are some cheap mods to get more power without breaking the bank. I was wondering why when I turn the chip up it will smoke real bad when I lug the motor, is that just to much fuel or what?

[lincster]

The smoke is just due to more fuel into the system, no big deal.

I love it when a diesel smokes.

 

You have done the cheap stuff.

You could put in different injectors.

 

If you want to see mods, go to www.thedieselstop.com.

lincster has it right, you've done most of the cheap mods. How big is the exhaust? You could try methanol injection. Othen then that... you be needin' propane, bigger injectors, bigger turbo and stuff. $cha-ching$

 

And don't worry bout the smoke....quite normal. Mine smokes like a train and I love it when I'm passing bicycles

I didn't see guages in that list. That was the first thing I did to my truck. Now, the straight exhaust, I assume you just deleted the muffler. You NEED a larger downpipe. So, get yourself a 4" turbo back exhaust. It is about $400. You also need a different intake. Or a Tymar type setup. (think cold air intake like you see in a rice burner....) pics on www.thedieselstop.com Anyways, you have to move ALOT of air in and out of the engine, and then add fuel. Now, on your truck, you will ten have problems with turbo surge. There are 2 alleged cures for this. One is an ATS housing. www.atsturbo.com That is kind of pricey, but can be had for about $405 from the right place. (www.dieselsite.com) It is ported, and eliminates most of the surge. The surge will eat the bearings in the turbo. It ate mine, and many others. I got it replaced under warranty, and right then and there, I put the housing on, along with a Wicked Wheel. Which is the second thing. It is about $70, from the same site as as you would get the housing from. This is a different intake wheel than the stocker. It has stepped fins, and is tuned better for the motor than the stocker. Both of these combined eliminated all of my surge. you will likely not notice any surge untill you tow.... Now, you can modify the MAP sensor. So that you can run over 22#'s of boost without setting the Service Engine light. THis is a must. You could shim the fuel pressure regulator to get you up to about 75 PSI, up from the stock at about 50. You could also get a Banks power Elbow which eliminates the factory Exhaust backpressure valve, and flows alot more exhaust out of the truck easier. You also could eliminate the Air Intake Heater plug. (AIH) This requires a Cummins engine drain plug, (M22-1.5 thread) which is available from any auto parts store, and is usually on the "help" rack. THe air intake heater blocks about 40% of the intake tract on the Y intake tract. It must be removed. You could also get a new torque convertor, to put more of the power to the ground. As you will eventually tear up the stocker if you aren't careful. But now you're getting into some bucks. All of the info on these mods can be found at the diesel stop. This is just the toip of the iceberg....

the black smoke is a cool factor but your actually just wasting fuel... now a truck with mods that doesnt smoke would be baddass .. just think if all that wasted fuel(black smoke) was actually getting used imagine how good your truck would pull..especailly with these fuel prices... my c15 500hp cat dont smoke at all but i see alot of 300to 425 hp motors smoking like trains cus they turn up 425p motor to try and get to 500hp ... i'll pull them any day... just bring it...

Im a CHEVY man, but I'd rather be CUMMIN' then STROKEN'

[MonkeyBoy]

I'd drive a Cummins if it didn't come wrapped in a Dodge.

[yamahanut98]

ha we have a cummins wrapped in a dodge, now then if only ford would put a cat diesel in there id be set

agreed. money providing of course.

[MonkeyBoy]

Ain't that the truth. I cry every month when I send the payment out for my 04 F350.

 

Although with the rumors of a Twin Turbo 6.4 liter diesel in 07, she may get traded in around 08.

[Spitfire]

Is it true Ford owns Cummins? And that sometime in the next few years, Cummins will be going into Fords?

[Proquad101]

So what exactly does the chip do to make the extra hp. I know a gas engine would advance the timing to get extra hp but since a diesel doesnt have "timing" like a gas engine where does the hp come from?

To put it in one word: No.

It does not have ignition timing like a gas motor. They use injector timing, pulse width, and injection pressure to deliver a different fuel curve.

 

In a diesel more fuel = more HP as long as there is adequate air to burn it.

 

In a diesel timing is all about when the fuel is being injected.
