mackr1989 Posted December 26, 2014 Share Posted December 26, 2014 How much would it cost to have a dynatard or engine brake installed in an 88 r model with a 250? Quote Link to comment Share on other sites More sharing options...
Popular Post mrsmackpaul Posted December 26, 2014 Popular Post Share Posted December 26, 2014 I wouldnt worry about a dynatard just open up the door and make the noise will work just as wella jacobs brake works about 20 times better Paul 3 Quote Link to comment Share on other sites More sharing options...
Timmyb Posted December 28, 2014 Share Posted December 28, 2014 I wouldn't be brave enough to guess a price. But tec brake do engine brakes for the mack engines. Apparently they do the replacement parts for Jake brakes also. I'd get a price from them, and speak to a good mechanic about installing them. We have an e7 with dynatards and they aren't great. My e6 has Jacobs but they aren't working just yet. Good luck. 1 Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted December 28, 2014 Share Posted December 28, 2014 an engine brake on a mack is like dragging a 10 lb. anchor behind a aircraft carrier!.......... for the money the exhaust brake will cost take the truck to a body shop and have a suicide door kit installed with electric windows, then when going down hill you can throw the doors open and then roll windows up or down to simulate one head or two. this is a exact replica of a jake or dynatard on a mack without the exhaust noise 1 Quote Link to comment Share on other sites More sharing options...
1958 F.W.D. Posted December 28, 2014 Share Posted December 28, 2014 Anyone have a Telma on a Mack? I have driven a couple of firetrucks with them and they work great, but are a drain on the electrical system when they engage.

theakerstwo Posted December 28, 2014 Share Posted December 28, 2014 I bid on a telma brake on ebay but the guy wanted to get paid with me giving him a card # and it would not go thru ebay so I reneged on the deal.I would have installed it on a CHI have a jake brake and did have a dnyotard on the engine that was in my truck.Not much difference.The dynotard will engage faster for up shifts and that is all they are good for.The doors open with the windows up and your Imagination will do as good. 1 Quote glenn akers Link to comment Share on other sites More sharing options...
bobcotkg Posted December 30, 2014 Share Posted December 30, 2014 Run a truck with a dynatard and complain about ituntil its broken, then you realize how muchit actually helps.I'm thinking those Jake kits are around $2500from Tec brake 1 Quote Link to comment Share on other sites More sharing options...

Superdog Posted December 30, 2014 Share Posted December 30, 2014 I gotta agree with storkmack,every Dynatard I ever had worked good. I was always told the secret was in keeping the valves properly adjusted. 1 Quote Link to comment Share on other sites More sharing options...
storkmack Posted December 30, 2014 Share Posted December 30, 2014 I gotta agree with storkmack,every Dynatard I ever had worked good. I was always told the secret was in keeping the valves properly adjusted.My truck had been sitting for years before I acquired it. Serviced the truck ran it a bit and the Dynatard worked good, had the valves adjusted and it works great. The best is when empty, shifting it like a 5speed with the Dynatard, makes the Paccar guys put air in the seat to see what just past their ass. 1 Quote Link to comment Share on other sites More sharing options...

gearhead204 Posted December 30, 2014 Share Posted December 30, 2014 well I can agree that a well adjusted dynatard performs BETTER than a ill adjusted one and yes they work great for speed shifting, but compared to a Cummins with a well adjusted Jake, .........well I don't want to start a fist fight! 2 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 30, 2014 Share Posted December 30, 2014 yes horses for courses Dynatard have heard some mixed results most bad however also have heard that there is a mod were there is some O ring you can pull out then it makes them work like a Jakebrake upon questioning people about said mod they all seem to loose there memory and have some were to go so maybe there full of crap or perhaps its a secret dunno some work better than others thats for sure from driving different ones I can tell I have one of the dudsPaul Quote Link to comment Share on other sites More sharing options...

57 bcr Posted December 30, 2014 Share Posted December 30, 2014 I like the Jakes I had on my '79 & my '90. Like Timmyb says,thats all TecBrake now as they bought Jacobs "vintage" business out. I like the fact that the Jake or Tec Brake is a bolt on deal. The Dynatard used a special cam,if I remember right. True,they don't work the same as on an 855 Cum-a-part,but they will keep you from doing brake jobs so damn often!

1MACK1 Posted December 30, 2014 Share Posted December 30, 2014 They are not the greatest form off engine brake around But after not having mine on an e6 350 for a few weeks its great to have them back But hey that's just my view Quote Link to comment Share on other sites More sharing options...
DCR Posted December 30, 2014 Share Posted December 30, 2014 Mack has a Jake accessory oil line kit that runs from the oil filter housing to the Jake heads. I had this added to my E7 460 and it helped some. The next time I changed oil I put 2 gallons of Lucas in and saw a tremendous increase in braking power. On a section of I80 in PA I had to apply brakes going downhill, after the Lucas I had to add throttle to reach the bottom. 1 Quote Denny330-550-6020A "Mack Pack" Charter Member Link to comment Share on other sites More sharing options...
