I've herd of a screw called the "smoke screw" that adjust how much black smoke you want to put out, I was wondering if any you guys have done anything with it, and i was wondering where its at and how to adjust it, i would love more black smoke!

 

 

not real familiar with the p pump but i think that would be on the VE pump on first gens like mine

 

I assume your talking about the star wheel on top of the afc housing. It controlls how much gas your putting in when taking off. The farther you trun it one way, the more gas you get when starting and going the opposite way (towards the engine I believe) backs down the low boost fueling.

Its not a good idea to adjust it without gauges because more fuel/smoke = more heat lower MPGs. Basically its a waste of time if you don't have any fueling upgrades and some afc tuning and all you will see are the negative effects...

 

I think he talking about the screw on the back of the AFC it has a little tin cover with a flat head screw in it and the other is a breakoff screw. Is that what your talking about bud?

 

The smoke screw is on the back of the AFC it pre loads the diaphragm. Use it to fine tune your afc setup.

 

All the added smoke in the world will do him no good without the proper equipment to monitor what the added fueling and temps are doing.Plus as someone already stated,just becuase you can lay smoke down like a train does not mean its making power.Along with most times the added smoke is just wasted fuel milage and money from your pocket.

-Gauges first,before you get started working on the truck.

-Plan your mods according to what will need to be addressed to handle the added fuel and power.Meaning just throwing parts may mean you spend money twice on some things,if you plan ahead then you may only have to do things once.

-Set your goal for a "realistic" power level.Something which will allow you to do both daily driving and playtime.The BIGGEST mistake I see new owners make is setting unrealistic power goals.Too much too soon usually means other things suffer and end up costing you money twice.If you plan your goals then the cost,while still may be high,may not be double or more over what you thought going into a project.

So with that in mind and knowing your a newbie I would say to get some gauges first to monitor your important functions.Then keep in mind when you do add fuel that stock drivelines(i.e.-transmissions and/or clutches)will only handle so much before they need addressed.This also goes for your turbocharger as while more fuel may be good for smoke,that added fuel will also increase your EGT's andthen you need to address the lack of air to cool it.Its a slippery slope but if you do it right then your cost may not be as bad.........Andy

 

thanks, but what exactly kind-of gauges should i get? I seen on BD performance diesel they have a guage package called a "X-Monitor Digital Gauge" It is suppose to show your boost, pyrometer, and Trans. Temp. Is that what you guys mean???

 

yah the x monitor will work. or you get get autometers isspros diprocal etc. You need at least a boost (0-60 psi) and a pyrometer.

If you have an auto its recommended that you get a tranny temp because the stock tranny doesn't like added power to much and a fuel pressure gauge is advised so if you do lose your lift pump or something else happens you will be able to know about it before it takes out the injection pump which isn't a cheap fix.
