Since the polling period has ended, I've contacted Harold from Pacbrake and we'll see how things go from there.



Thanks,



Matt

hey if pacbrake needs anyone to help test them im willing to provide a truck

I'm with Mhannik, I'd love to be a guinea pig for something for once.

could we also take the next logical step and just cast a NEW better flowing head w/brake ? maybe even aluminum? it would justify a better price and also make engineering easier! why pay 2k for an add-on brake AND then 2k more for the ported head?

as i hear it there is an aluminum head and block based on the 5. 9 cummins that is designed to run alcohol. from what i am told all the cummins parts will fit. i bet its not cheap

Wouldn't we all???!!! Oo. Oo. Oo.

Okay guys I'm going to print this thread and hand it over to our engineeering department for design review. Lets hope all of your request help them get a move on.

Thanks for your help Harold!

 

[redfuelrules]

Thanks. This would truley be a great thing for all of our trucks. It would also be alot of fun to rub it in the faces of all the GM and Ford guys: Still think your goofy V8's are better?

If you look at the pictures on the link you have you'll notice that it is an exhaust brake just like everyone else has been selling, not a true "jake brake" like what we're after.

I wish I could remember his name, but the guy I spoke with at Jacobs about my exhaust brake was one cool dude. If your exhaust brake is made by Jacobs, it IS a Jake Brake... Jake Brake is a registered trademark, so much so in fact that Jacobs sends letters out to cities asking them to remove their ordinance signs prohibiting "Jake Brakes".



Right under my 3500 CTD badge is a Jake Brake badge, courtesy of Jacobs... I'll post a pic when I can. Looks way cool and gets tons of stares, questions and comments, mainly, "I didn't know that Dodges had Jake Brakes!".



While I agree that an engine brake would be a great novelty, my Jake Brake exhaust brake works just fine for me and what it was designed to do, but I would love to see and hear the results of this endeavor.



FWIW, this is what Jacobs has to say on the subject:

FLynes- That link was pretty cool. there is a pretty good diagram a ways down that shows how it works pretty good.

 

[FLynes]

Yeah, I love that website, and the guys at Jacobs are phenominal with their customer service too.

harold i dont wanna sound pushy or anything but any news on this go or no go?

 

[KAlder]

I'm gonna ask Santa for a Christmas miracle. Got to work on a crane mounted to a Kenworth today, I "accidently" left the Jake on while I was testing out my work. :-laf

Boom up... ... . BLAAAAHHHH... ... Swing left... ... . BLAAAHHH

SWEET!!!!



Too bad I missed this poll while it was active. If the price was right, I'd jump on this one--ESPECIALLY if it could incorporate a better-flowing head.

 

[KAlder]

Anything new Harold? Can I give you my credit card info yet?

 

[Mhannink]

well guys i dont know if harold has told you guys through pm but i talked to him a while back and he told me r&d said no go. reasons being besides needing a body lift there would be extensive head work required and the cost would not be effective to the consumer.



i know we are all disappointed but it looks like exhaust brakes are all we get untill someone works out a low profile high flow head

You'ld think SOMEONE would've done this by now!! #@$%!

 

[Mhannink]

you would think so but not yet the only head and blocks for that matter that i know of are aluminum and meant for running alch

 

[JAmos]

I brain stormed on this one for a while, but came to the same conclusion of the necessity of a body lift. If the engine didn't sit under the cowl, then there would be more possibilities. Its been a few years since i messed with jake brakes in diesel school, so I can't remember what sizes the piston and slave cylinder assemblies are but the 2 cylinders under the cowl just hang the idea up. Not enough clearance and not a cost affordable way to get the necessary clearance. Not unless someone designed a hemi head that would allow mounting the exhaust brake assemblies at enough of an angle to be feasible.



The only way I was thinking that would be possible is to maybe use/design a low profile slave cylinder ***. that would recieve oil from a high pressure pump with a clutch, like an a/c compressor. If it was possible to get enough oil pressure from the pump, then it might be possible to use a small enough slave cyl. that would fit.



Don't get me wrong, I would love to have one on my truck, just don't see it happening.

Don't forget some of us don't have any cowl to worry about us 1st geners don't have to worry engine is out there ... easy to work on. . and I'd think most 2nd and 3rd gens owners wanting a engine brake would spring for a 4" lift in order to mount it etc... .

Thanks,
