smoke?
 

alright so diesels are supposed tosmoke right, well most of the new ones don't stock but on any diesel the more fuel the more smoke the more power, well my friend whos only 16, says that black smoke is bad and it clags up your engines, i think that smoke cools the injectors nozzles to but any input would be great thanks.

P.S> another one of my friends says that turning in the full fuel screw about 4 turns will melt down the injector pump, i doubt this is true but any input again would be nice. :humm:

The pistons will have issues with heat before the injector nozzles do. More smoke doesn't necessarily mean more power, it means you're dumping more fuel in. If you have the airflow upgrades to support burning more fuel, then you'll make more power. The soot really isn't going to clog the engine up, it's going to burn out of the combustion chamber; the main thing is it will soot up the oil so you'll want to change the oil a little more often or at least change the filter more often.

I don't know how much you can turn the rotary pumps up before it's too much pressure; but I have been told that you want to put injectors in if you're turning the pump up very much as the VE pumps don't hold up well to really high pressure.

^^^^^What he said.^^^^^^:U:

alright thanks guys :U:

if you turn your pump up too much you'll have a run away and your motor will blow up unless you can cut the air to the turbo

think you could stall the motor in runaway with a 5 speed?

Not unless you had a twin disk clutch. I don't think a single is going to hold one back if you dumped it. I would bet it would eat the disk. I would definatly give it a try.:w2:

i highly doubt it will kill it by dumping it, my guess is it will slip the clutch till it wont hold any more or the truck will take off :booo:

ha ha ya ill just turn it way up then try LOL.
I would think throwing it into 5th and dumoin it would work but i dunno

get the phone book ready:w2:

still dont think it will work but good luck trying:U:

Q. alright so diesels are supposed tosmoke right
A. No

Q. but on any diesel the more fuel the more smoke the more power,

A. not completely true if you smoke you are not burning the fule the (sweet spot) is lots of fule with the right air mix and NO smoke

Q. well my friend whos only 16, says that black smoke is bad and it clags up your engines,
A. hes 16

Q. i think that smoke cools the injectors nozzles
A. no its the fule in the injectors that cools them that and the engine coolent and turbo air

Q. another one of my friends says that turning in the full fuel screw about 4 turns will melt down the injector pump,

A. no throw it in a fire to melt it....lol

well put :U:

thanks only correct info is good info
:5:

either way your gonna break shit use a phone book or a wood block the best is a 5x5 peice of mudflap jb welded to a 4x4x2

i resent the 16 remark... i know alot more now than i ever did when i was 16; but i dont believe i was that nieve, gotta start somewhere even if its with the wrong info... as long as you arent an arrogant and pompus little jack*** like most 16 year olds are and can be told and listen to the correct info then everythings good lol other than that... pumps dont melt down; pistons do. fuel cools; cold charge air keeps cylinder temps down and the one part of the engine that DOES like to melt; the piston from actually melting... sooo yeah big bad pretty much summed it all up

diesels arent supposed to smoke but the problem is; in order to get the ammount of fuel you need for more power when boost is present tends to result in heavy low boost fueling... WOT at the highest charge air pressures its acceptable to "haze" slightly. this is where the "sweet spot" is

also big bad... if you throw a perfectly good pump in the fire i'm pretty sure i'd have to :ph: and when dealing with a run away... cutting off the air or a carbon dioxide fire extinguisher is the only route to go... dont tear more shit up while your trying to prevent that... anywhere past 3 turn ont he full fuel is where it tends to hang in RPM's.... almost shit a brick, gave it a turn plus half a turn and snapped the throttle and it decided to hang and then come back down... i hurried up and back it off 1/2 a turn :w2:

also well put :c:

that about sums it up

Exactly!:U:

Alright i guess i don't know anything and i need to be quiet but thanks for the input.

the way i see it, if ya dont ask, u wont know :U: most on here dont mind giving some advice

thats why i like this site

x2

ya thats true. thanks guys

I only said give it a try if the thing ran away and you were not ready or unprepared. I didn't mean do it as a rule.:ph:








.

i can see that... if you catch it early enough in its run away i'm sure it'd be possible with minor if any ill results... it should be pretty easy to catch up to, it they run away at idle they tend to climb slowly; not sky rocket... however if your in the high rpms and it stick in the high rpms then decides to start climbing... find some balls and bend over the intake hose as best as you can; should make it spit and sputter and keep it from blowing apart. best bet is to be prepared when your doing fuel mods
