hmm nout wrong with …
hmm nout wrong with it just need runing a little bit longer before the pull
This is a reposted …
This is a reposted video. They did not have time to warm it up before the run. There are other videos of this on youtube.
Not good

Most high …
Most high performance diesel engines that run 60+ pounds of boost usually have a lower compression ratio to keep the head on the engine.. SO when the engine is starting you obviousley don’t have the boost to make the engine run right, so yes you get unburnt diesel and white smoke. Diesel engines use the heat of the compression to ignite the fuel, so if you have a lower compression ratio you will have a hard time starting the engine.. Ever try to start a weak diesel on a cold day
The white smoke is …
The white smoke is probably because of the water injection, but it’s rare to see the water injection turned on at idle, usually it’s turned on when pushed down the throtle.
Why even try?

not sure if it …
not sure if it relates to this video but white smoke on a deisel is cold unburnt fuel and obviosly black is warm unburnt
wow didnt know …
wow didnt know stupid came in so many ways
They lower the …
They lower the static compression ratio to keep from blowing heads, head gaskets etc…. not because it allows to more fuel and air to fill the cylinder.
this video was good …
this video was good
energetic fun smart and loves this video Uz
thats not thru!! …
thats not thru!! read the other comments, power in this engine’s is coming from the max turbo boost , the more air you can get in the cilinder, the more feul you can combust, the higher the explosion force!, in normal diesels you can’t get as hy forces by max turbo pres!, , its nothing like a normal diesel!!
Nobody………No …
Nobody………No matter where you are from can talk about that pull!! That bad boy right there is ready to do the thing! You got the right recipe !!! you will learn more about diesels and pulling as whole by keeping your mouth shut and your ears and eyes open, than you ever will getting told about it…..Southern Virginia. USA…. Over and OUT!
hey man. im naked!! …
hey man. im naked!! p
i can´t see any …
i can´t see any trouble
engine can rev …
engine can rev harder with less compression
Low compression …
Low compression pistons to allow more fuel making more boost from turbo/s
Holy Smoke, what …
Holy Smoke, what was wrong with that thing? it sure seemed to do good during the pull, though.
850dan: nobody even …
850dan: nobody even makes a 2-stroke diesel for automotive/over the road truck use anymore they were useless lag pigs no power and leaked more oil than they could hold.
White smoke was from really low compression pistons 10:1 not enough compression to fire over the diesel fuel until the cylinder get hot. The lower the compression the more room there is in the cylinder to fill with diesel and high boost pressure from the turbos. All really high performance diesel engines de-compress like this.
hey my grandpa told …
hey my grandpa told me that and i think he nos alot more than u guys do
You can go for …
You can go for higher turbo boost with low compression.
oo i didnt know …
oo i didnt know that one i made my self look so stupid but why i dont get it ? why do they take as much for lower commpression ? but i know that in regular cars the more commpression the more power
Do you know what …
Do you know what your talking about?
When they take out these powers from a diesel engine they lower compression as much as possible.
you are …
you are stupid the more commpresion the more power !!!!!!!!!!!!!!!!
the higher the …
the higher the compression the less power,the smoke is white because its got a turbo.the black smoke is made by the intercooler.
