Jake brakes 8v71

[eagle19952]

Loud pipes can only be heard behind you.  They do nothing for left turners or anything else, this backed up by insurance studies.  I say this as a motorcyclist and instructor for 40 years.  I ride with quiet pipes.  I have no time for straight-piped bikes, I want them outlawed and off the streets.

Off topic or what?

you brought it up....I actually think jakes in a tunnel are a lot more irritating....agree ?
so your pipes are glorious and harlyman's aren't.....little one sided....

I made sure to be in first gear and with the jakes on going through that tunnel, and the sound was glorious!   I made sure to be in first gear and with the jakes on going through that tunnel, and the sound was glorious!  I live on a road that lumber trucks pass by, and some of those are straight-piped and have seriously loud jakes, I like the sound of a truck working.  Loud motorcycles (the really loud straight piped ones) piss me off, that is noise for noises sake, but a truck working hard for a living I like.  I wave, they wave back.  It's a Maritime thing maybe.

My little bus has an exhaust brake.  I tried it out today for the first time on a long 7% grade near me.  They held my bitty 10,000# bus at 45 mph all the way down the hill.  I'm sold!

BTW, the bus climbed the same hill at over 50 mph with its little 5.2 l 4 cyl turbo diesel--I'm stoked!  Still, it would be nice to have a real bus  .  Jack

Jack-at times it's nice to have a smaller motorhome. While I like my 40ft'r, I'm looking for a less than 25ft'r to be able to do quicky weekenders-say to state parks that mostly have 25ft restrictions. Something like the Lazy Daze 24ft twin king is what I'm talking about. No slides, huge windows. Good luck, TomC

Tom I have a 1973 Winnebago Indian for sale, great motorhome, very solid(back then they had a lifetime warranty on the body), rebuilt engine, new tires, everything works including the Onan Generator and AC, all original paint etc. At 22feet long and 10 feet high you can park it just about anywhere. 

[TomC]

Funny thing-we rented a brand new 1973 Winnebago Indian 22ft with 413 Dodge engine in it from the owner-hadn't even taken it out for himself yet. Not a bad rig, but rides like a truck. I imagine putting air suspension in the rear would solve that. And not a fan of the sandwich walls used in the 70's. Good Luck, TomC

Brian I have heard bikes come up behind me on the freeway going 70 and I have had no problem hearing them, it's true some are very quiet but some you can clearly hear coming up from behind, don't know where that insurance company study came from but I don't think it is all that correct. Just saying

I have had buses pass me running straight (no muffler) exhaust and the noise is terrible.  It makes a straight pipe Harley sound like a Honda Civic.  I have Harleys and when I boosted my 80" Evo to a Stroker 89"er I went with the "Thunderheader" pipe-- the noise was so bad I had to wear eaplugs and that was not enough.  Finally I sacrificed great performance by putting the stock pipes back on.  Still hauls @$#, but I can live without performance for some peace and quiet.

I would never run straight pipes on my RTS bus conversion.

Excellent subject matter by the way and thank you.  Now my story.  Way back in about 1970-71 when I was pretending to go to college I drove a School Bus part time for the Kern High School District in the pretty city of Bakersfield CA.  My daily assigned ride was a fairly new 1963 Crown Supercoach 40 foot 10 wheeler 92 passenger bus. 

The route then was daily down then up the Grape Vine South of town on Interstate 5, although it might have been named highway 99 back then.  Too long ago.  Anyhow, a 220 hp non turbo 743 Cummings.  Jake Brake.  RTO 910 Fuller.  With a full load of about 50-60 kids, we came down the Ridge at about 25-30 mph without touching the brakes. 

The Jake was an incredibly effective SAFETY DEVICE.  Also about tranny retarders;  I will NOT tell you a true story where a unnamed fire agency fire engine was returning from down South coming down the same North bound Ridge Route at 75 mph with the Allison retarder in the "max" position.  Burned up the automatic tranny.  Big $repair$ job.  The stupid so called "deserving" Engineer did not know what he was doing, which is typical.

Jake Brakes dump about 70% of the absorbed heat energy back into the water radiator and 30% out the exhaust pipe as heat and noise.  This keeps the engines warm going down steep grades, which is good.  Auto tranny retarders dump all the heat into the tranny oil cooler with mixed results.  However ... Telsa, (sp?)  type retarders are fine?

Jakes work.  Yes they are noisy, which is part of the fun, games and giggles of owning a Bus Conversion.  They also have a particular place in large fast coaches that tend to come down the hills as fast as they went up them which could be exciting at times.  You will be very happy with a Jake Brake.  I would not own a Bus Conversion without one.

PS;  I now want to do a cheap rat rod street pickup truck powered by an old DD 353N.  Why?  Because it can have a Jake.  A real one. not a potato brake.

Just me.  HB of CJ (old coot)

Am I the only one who only wants jakes for one reason and one only? The noise

Nope Scott your not, I also would like a set for my 6V92.  My Harley also has loud pipes and has saved my but a time or two.
