Which turbos are the ones that spool really loud?

The 'Detroit' Turbo I have is really loud when it spools up, especially with the twin Donaldson Air Cleaners.
It does border on annoying if the windows are down.

 

BlackW900, whenever I saw the Freightshakers in your sig, I had to do a double take! #1, & #2 are almost identical to a pair my father purchased. They were part of a large fleet originating in North or South Dakota, (forget), some of which ended up for sale in Houston TX. The two my father purchased were 1971s, with the smaller "White Freightliner" radiator cap cover. The paint scheme was identical to #1, in medium blue & white. The deal included a new paint job, and I stayed with same scheme, and colors; father chose to paint his that red and white scheme #2 has.
Some of the options chosen by the original purchaser were :
Look closely you young guys!!!!!!
(1) The 270 Cummins, upgrade from the 250 HP, (220 HP may also have still been available.) Cummins offered the "big" 335 HP as the high end.
(2) RTLO 9513 , A 13 speed built to withstand a whopping 9500 ft lbs of torque.
(3) 4.44 ratio rears
(4) NO air conditioner! none, nada, zilch, zippo.... (remember, from the factory like that!)
(5) They did have the full padded interior, with the 71" cab and sleeper combined, the deluxe models got two hooks to hang clothing, NO closets were available. A cubby hole behind the driver seat was also thrown in, size was approx. 8"x36", for the trivial stuff like socks, briefs, paperwork, tools you wanted to store inside, etc.
(6) The 24 volt starter, which incorporated a parallel switch that had a life span of about 3 months. The Cummins did have a compression release, which IMHO no truck should be without, even this day and age.

Sorry to get off track, that picture opened old memorys for me.
Getting back to the turbo thing, my father, as did a lot of other people, believed no turbocharged engine should have a muffler, which I think is the main reason I need to learn to read lips.

 

Started out on a 1693. To this day, imo, that was the sweetest sounding turbo.

 

YES! The 1693T/A was the best sounding Cat ever....The turbo never sounded better on any engine.

 

X2!!!:smt023

 

There certainly is a lot of "I'm better than him" in this thread.

I suppose anyone who seeks to personalize their trucks in a manner you don't like must be inferior physically. How is that in any way reasonable to assume?

I'm the only person who has to deal with my truck for more than a few passing moment. I am fairly courteous with my truck and I do fully recognize a lot of others are not.

As far as that driver in the video being a "nondriver" I think that's utter horse crap. I believe such statements are typically inflammatory and devisive simply for the sake of being so. He's a touch irresponsible but clearly capable. I'm quite certain how he drove in that video relates little to how he drives in the course of duty.

Additionally, tearing him down for being willing to drive his truck hard because its hard onhis truck? Well, since you don't spend his money so get over it. I don't berate people over their choices that only effect them. I doubt you could judge from that video if his truck was in a safe operating condition either, so no argument about if hes ragging the truck out.

 

I wasn't going to jump in but can't help it. While viewing that video, two things popped into my head.
(1) Noise ordinances
(2) Professional drivers, (or lack of)

If you'll read my earlier posts about those old Freightliners, I did not add any more, because I had already gotten off the thread's subject......Now I can; My father had acquired a third Freightliner some months later, when my BIL decided he wanted to be a truck driver. His truck was specced similar, but a 1970, with a 10 sp. Removing the mufflers was right up BIL's alley; he liked that sort of thing. It didn't take long for him to get banned from one of the small towns we moved a lot of grain into, and out of, due to the straight pipes. Funny thing was my father, myself, and others had the same setup in their trucks. BIL wasn't the only one to get banned, but a whole lot of us never got hassled for no mufflers on their trucks.

 

I won't say his use of the Jakes near a couple of houses, and the guy walking his dog, wasn't a bit unnecessary. It was. Being during the day, and over fairly quickly, it wasn't the worst offense, though offensive none the less.

He was most likely speeding, but I'd guess not by a whole lot. I saw one posted 45 zone and I suspect he wasn't more than 10 over at any point, and not for very long. Certainly none of us can really guess how fast he was going accurately. He did slow down quite a bit and fairly quickly for the guy with his dog. There wasn't any traffic to deal with that I noticed, so I don't think he put anyone at great risk.

Since we can't really tell what kind of truck it is, and if it's a day-cab or not, I won't speculate if the truck exceeded the road's weight limit. It's just as likely it did as it is that it didn't. Being bobtail, he likely still didn't exceed the limit by very much. Shades of gray...

He passed a couple houses in the country/on the edge of town. He started in an industrial/business park looking area. Hardly in a residential neighborhood.

I have straights on my truck, but I don't abuse people with my jakes. I have never heard of any complaints while others have, doing the same jobs as I have. I don't use my jakes in town, around the yard, at shippers/receivers, in front of houses close to the road at night, etc. I afford extra respect for things like hospitals, fire stations, etc, even when they are in areas I'd otherwise use my jakes in. Even with mufflers, a lot of areas are still to dense to use jakes without irritating people.

I use my jakes basically everywhere I need to without violating posted laws or obviously offending people in there homes. It's all based around common sense and common courtesy. Certainly, many people lack one, or both of those.

I just don't agree with ripping into this guy as being a unskilled, unsafe, or otherwise incapable driver. It's more rude to berate him than was anything he did in his video, IMO. I'm sure a lot of people would agree, and likely just as many disagree. Treating someone as if a piece of ##### is not helping make the industry any better either. It's a smaller thing, but it's this adversarial, divisive attitude that is the root of the larger problems between drivers.

 

I've got an MBN C15 flashed to 6NZ, pitts power mufflers, with the Borg Warner turbo Haney recommended... It's a single air cleaner T600. My turbo whistle is loud. I can hear it under bridges and in tunnels really well. Sounds good I like it... I remember when I used to drive a company ride at night with the windows cracked and could hear large cars that sounded really good passing the other way, not talking about loud pipes either, just free flow mufflers and a nice turbo whistle.. I like to think that's what mine sounds like now lol.. And my ol lady hasnt complained about any shrinkage in my manhood either lol...

 

I thought this thread was about Turbo whistle and what was loudest? Can we answer the mans question as I am curious also. I always thought Holset myself.
