Turning to much fuel to something makes the engine run hotter which can lead to burnt pistons.

thats the reason I am dumping almost 1/2 a gallon of water into the intake system durring a 300ft sled pull. It not only gets my EGT's down to 1400 degree's but a bunch of horsepower is also created.

One thing that you should know though, that alot of people don't know...with the size of injectors I am running and my fuel mods...just the fuel alone is acting as cooling. One reason how guys can run in slep pulls with super high HP where they are not alowed to run water.

DUMB SHIT, diesels make FAR less co2 than any shitty fuckin gasser....

cleaner than any fucking prius. start up a prius in a garage and see how long you live (about three to four hours) start up a diesel and see how long u live (three to four days)

I want a diesel bad but damn they are exspensive. a 01-02 duramax silverado is 18-20+K in excellent shape vs a gas engine 01-02 in excellent shape at maybe 12K. im torn between the two..Im not doing any major hauling so a gas engine best suites me but i want diesel lol

dude where did u get ur cowl hood!?

Name of the video should be renamed to "First boner from hood stack"

Why does everyone insist on bitchin about everybodys videos?

@urbex2007 That true 100% but in truck pulling if you are physicall you using all that fuel and it no longer smokes...you are going to be having major EGT issues. When you get to the point that the water injection won't cool it down enough or the air/water intercooler, the only other option is to load up on the fuel which helps HUGE in lowering the EGT's and its proven that it doesn't hurt the HP all that much on a 1200-2500hp engine and it keeps engine from having a total melt down!

ok about the egts you all have to undersatnd black smoke is fuel that does not get burned completely so therefore if the fuel is not burning then it acts like a cooler for the pistons and also black smoke occurs when the turbo has not caught up to the amount of fuel in the combustion chamber a turbo is driven by exahust gases its not like a super charger that is directly hooked to the speed of the engine it takes a little bit to spool up

@RiceReaper Oh thank God someone who talks sense. That's two of us that now about engines then. Why do people think that injecting more diesel gives more power when power is limited by the size of each cylinder. Unless they are made bigger the extra excess diesel burns off in the manifold, turbo, EGR and CAT causing serious problems. There are so many idiots about who think smoke means power when really SMOKE=BROKE! Do the same on a petrol car and it's less forgiving.

[urbex2007]

@RyanBambach The main thing people do not understand is that black smoke is unburnt/unused diesel. Unless you make the cylinder size bigger to accomodate all that extra diesel thrown in - it will just burn off in the manifold, turbo, EGR, CAT etc. It doesn't produce any more power. Efficient powerfull diesels do not smoke. The black smoke is for show and indicates a detuned inefficient engine. It soots up the engine components too. Also indicates an ECU/fuelling problem which causes damage.

@atlasrgstr ... too rich means you have to replace spark plugs and o2 sensors running lean is what brings your egt and other temps to dangerous levels. fuel is what cools the pistons
