Some pics of my dirty girl :D

[NUTNDUN]

Sorry guys, no nudies... ... LOL



I figured there would be some class 8 fans on here and I figured I would post some pics of my favorite diesel. She is a little dirty from running in the snow today so I didn't totally lie for the title of this thread... . LOL I was taking pics of the dodge for the classifieds and figured I would take some of the Petercar.

Hmmm... Not quite enough light on the front bumper. Good looking truck.

That is a nice truck. How about some 8" stacks?

I like 8" stacks when they are straight or miter cut, when they have the bend in them they kinda look funny, I would like to get a set of 6" bull haulers with the older style elbows that come all the way down to level with the bottom of the tank and then go under the frame but that kit is alot of $$$, lol bought the same as 8".

I will try to take a pic this morning, I am hoping i don't have any trouble starting, got below 0* here and I didn't plug in. I know the motor will fire off if I can get it to turn over, the starter doesn't like turning the kitty kat over in the cold, you can smell the starter burning in a matter of seconds... . LOL I will take a pic from the inside looking out, I love seeing the big hood out there, and all the gauges... lol

I've been wanting to ask this question and since your Peterbilt has them maybe you'll provide the answer.



I notice that many West Coast trucks have twin stacks. I know that many West Coast trucks have higher horsepower engines for traversing the Rocky Mountains.



Do the higher rated engines require twin stacks for improved performance or is it just for the sound and appearance? Obviously a V8 performance car engine makes more power at higher rpm with dual exhausts because the exhaust system improves exhaust flow. But V8 engines split exhaust output naturally due to engine design. Do the higher rated big truck engines use a split exhaust manifold with three cylinders exhausting into each stack for improved exhaust flow?



BTW, I use a screen saver on my PC downloaded from the Peterbilt site. I enjoy admiring the big Peterbilt 379s.

The exhaust manifold is just like on our cummins, 6 into 1. My exhaust on the pete splits into a y right about the end of the steps then comes out the side. Right now the exhaust is 5" from the turbo all the way out. Alot of people with the classic style trucks have dual air cleaners and stacks... . actually dual everything... . it is like a class thing I guess, the more chrome you have and that what is on one side of the truck matches the other side. My truck has a 550 Cat with 1850 ft lbs. , there are alot of the C15 cats in single air cleaner and single stack trucks but I would have to say that better performance is a definate with duals. I know switching to straight stacks especially on the C15's and bigger motors there are alot of guys averaging . 5mpg better along with 1-3 extra psi of boost and a few degrees cooler egt. My egt probe is post turbo on the down elbow and when I am pulling a couple mile long hill as long as I keep the rpms at 1300 or above my egt never goes above 950* even in the summer. I wouldn't want to run a big motor with singles. If I were to put the Pittsburgh power box on it, to be able to run the higher settings you have to put the bigger turbo and free flowing exhaust on to keep the egt's in check, and thats even with duals. The Pittsburgh power box will hopefully be on the truck in the next couple of months, I mainly want it for the fuel mileage but the extra power won't hurt... . lol . The box is like $2,500 and the turbo is like another $2,500 for a 200hp and 500 ft lbs increase. It would be too much power for what I do now, I have to take it easy on the low side or I waste the tires away, I usually quarter throttle through the first 14, then once I get into the top two hammer holes and splitting either one then I lay into it. I don't care what anyone says either about big motors and fuel mileage sucks, it all depends on what the person does with their right foot, last summer I averaged 6. 25mpg pulling 42,000+ all the time local.

If anyone is ever on the east coast, mainly in the PA-DE area especially on I-283 or 81 feel free to flag me down if ya see me, I'll buy lunch.

sweet lookin rig!!!!!

I think I have seen your truck before, I'm surprised I don't see it all the time since I live in Ship and drive to Harrisburg everyday. We just bought a new place in Newville and we are supposed to settle at the end of the month, I need something with land so I can park the big truck and build a pole barn, would be really sweet to put a dyno in too but I think the wife would kick my booty... . LOL

NUTNDUN:



Thanks for the reply and information. I've admired and been curious about Class 8 trucks since I was a kid. I guess it is the same internal drive that causes others to be fascinated by trains and others by airplanes, powerboats, or sailboats, weapons, computers, whatever.

Hey Harvey,
Same with me, dad drove all his life and now me... LOL I love trains, I pull for triple crown which their trailer travel most of their way by train and we haul em from the yard to the customer within a 300 mile radius, triple crown is a division of Norfolk Southern, granted there are alot of times we get held up by the trains and then I don't like em that much LOL but I love hearing them sitting there idling and when they first lay into it to get the train moving, it is absolutely amazing the weight that they move. It's almost like a wet dream when there are 4-5 engines tied together, better then the wife whispering sweet nothings in my ear... just don't tell her that. LOL

I like their sound too and also love to feel the earth hum when a big diesel electric locomotive begins moving a long train of heavily loaded railcars. Back when I was a youngster in the Navy I spent about three and a half years in the mid-60s as a crewmember of a diesel electric submarine. It was powered by four huge 16 cylinder diesels, each spinning a dc generator that powered the electric propulsion motors. It's been 40 years so my memory may be failing me but I think they were GM16-278s. Sixteen cylinders, each with 278 cubic inch displacement. I think the engines were actually railroad locomotive diesel engines. Crossing the Atlantic in the winter with those big engines sucking cold air through the control room hatch, down through the control room, crews dining area, and crews bunk area was not comfortable. After living and working a few feet from those sounds for several years I can sleep like a baby in a truck stop.

Would racing stripes on the side help improve fuel mileage? Sweet looking rig.

I agree I like straight 8" stacks the best. They look good and sound awesome. Here in NW Iowa, where I go to school, there is a lot of Pete 379s that haul livestock with this setup. They sound awesome!

LOL possibly, aerodynamics of the stripes would help with air deflection...

I did hear through the grapevine that taking the stacks off and putting two of those big fart cans from a ricer will yeild 50+ horsepower, they say too that all the racing stickers will gain more power but nobody has dynoed to find out... . LOL

Definately #ad
, anything with 6" and bigger straight sound awesome, especially when the person is good with the throttle and winds her out to 2000 rpm, pulls it out of gear for the upshift, insert big turbo whoosh here, then blips the throttle to match everything up and slides er in the next hole, then hammer down. #ad
