Better engine braking?

Mine must be broke then, when it's on it comes up with 24lbs of boost at times when it's cool out.

 

First of all maxxforce is a European engine, a bad one at that! they are known as M.A.N here, their engine brake isn't really a Jake, engine braking was never developed here cos we use retarders, I don't think there is much you can do to improve it unfortunately !

 

I have a 2012 prostar same company as Ethan with 21000 miles and the Jake brake is worthless compaired to my old.Columbia previously I had. I'll look into it as well next time I'm at the dealer.

 

Hhmm, I was chatting to a guy with the same complaint as you and his maxxforce only had the same engine brake as we get here, basically makes a bit of noise and not much else! Yeah they probably are fitting proper jakes now but how well designed are those engines to take them? What I mean is say CAT and Cummins, Detroit etc are US engines so are designed for jakes I'm not sure how well a euro stove would react to them?

 

Yeah I wouldn't doubt you for a second there!

 

On which part? Going to the dealer? Worthless engine brake or both? LOL if nothing happens I guess like previous post said ill have to adjust to my driving habit to creeping down mountain grades which is fine, its better then being a multi ton missle barreling down it. Maybe has to do with the governing of our truck Idk. Other than the power and engine brake she's a dream to drive and has a lot of perks over my previous truck.

 

No it isn't a MAN.
It is a International build with some aid from MAN.

Who BTW aren't using the MEGR platform for obtaining the same levels off pollution.
They will go the DEF-EGR way,as all other brands.

 

The block here for the 11 & 13 ltr engine is a MAN block. The only engine that is a CAT derivative is the 15 ltr. The 07 product had just a butterfly valve. The 2010 product has an actual Jake brake. Also programming can be an issue if your truck has fleet specs and could possibly impact jake performance.
