Why does "Overtime" have a small pipe next to the stack?

[BigTruck27]

@drockgibson There is a wastegate installed on the turbo to prevent it from creating so much boost that it damages itself. It works by blowing off the excess exhaust gasses and, in this case, there seem to be so many and they're so sooty, they were vented out through a small secondary hood stack to keep the engine area from being bathed in black smoke.

[arbcruiser]

the black smoke is fuel that is burned thats why it is black

[dodgedude101]

black smoke is non burnt fuel...you can not make horse power out of a diesel without black smoke

[jaybrown1012003]

untrue, you can make plenty of hp without the black smoke

[dodgedude101]

prove me wrong....you show me a diesel pickup that has lots of horse power an doesnt blow black smoke.....not possible dude....unless you run NOS thats the only way

[granderd]

why does it blow white smoke in the beging then it goes in to black smoke?

[jaybrown1012003]

the black smoke is unburned fuel.

[dodgedude101]

these guys are runnin water injection into their turbo's thats why there is white smoke at the start

[granderd]

thats what i thought i wasnt for sure on that

[dodgedude101]

ya....like these guys are runnin so much horsepower an boost they need the water injection to keep the turbos cool an sometimes they sit at the line spoolin up cause their runnin alot of fuel to the motor an tryin to get the turbocharger hot enough to burn the water

[DieselDoc83]

water injection keep the motor and egt's down enough so they can run 300ft without melting a piston since there all "filled" blocks plus the water can add more horse power since it turns into hydrogen in the cylinder

[DieselDoc83]

ummm you mean into the intake...water doesnt get fed into a turbo

[dodgedude101]

ya thats wat i ment thanks.....an water injection is a good way for some good horse power add....so is myth injection but some pullin classes dont allow that stuff

[tvoidt]

Actually is because of the low compression.

[dodgedude101]

lowering the compression in a diesel is a good way to get more boost an horse power....

[tvoidt]

Yeah, i know. Same goes for gassers.

[dodgedude101]

no for gas engines you want as much compression as you can get out of your block.....gas an diesel are different.....diesel you want lower compression an gassers you want higher compression

[tvoidt]

Wrong.

[dodgedude101]

WTF you mean wrong....if your want big horse power with a gas you go with higher compression...like say my broothers 454BBC it went from 9:1 i think thats wat they run stock not sure...but anyways....he bored it .60 over so it s a 468 now an it has 13:1 compression an runs 650hp....but tell me why i'm wrong

[tvoidt]

I'm sure his motor is naturally aspirated. If you lower the compression and turbocharge the motor you can run higher boost pressure. Same thing on a diesel.

[dodgedude101]

oh you never said anything about a gas runnin a turbo now...lol...but ya i suppose you are right on some parts...you can take a stock gas an run a turbo without lowerin the compression

[BigTruck27]

@dodgedude101 Generally for gas engines, 10:1 compression is about the max with standard pump gas, due to pre-ignition or detonation. (ignition of the fuel/air mix prior to full compression & sparking) 14:1 is about the max possible using high-octane leaded racing fuels. Diesels are compression ignition engines. (no spark plugs) They rely on very high compression to heat the air and ignite the fuel which is injected into the cylinder at the top of the compression stroke. 20:1or higher is common.

[dodgedude101]

@BigTruck27 ....ya i know, my brothers 454 is 13.5:1 compression an my 96 12 valve is 15:1 from 21:1 stock lol

[digzie1]

god ! that ford S U C K E D ass ! he should find the highest cliff and push it over with a dodge ,lol..

[Snowgoer05]

Stupis ford frames! PUT THAT IN A CHEVY FRAME THERE A LOT STRONGER!

[JSRmontcalm]

uhhh no. not even close.
