Go eazy on me here guys
I have never owned a truck with a Ebrake and dont know anything about it, but since its on I might as well try and use it untill I land my twins on.
I got this truck that has a BD brake on it and have read that people use it to aid in warm-ups. Whats the deal do you just fire up the truck in the morning and throw on the brake while its at idle? Is there and downsides to it?

 

I start mine, and let the oil pressure stabalize before turning on the exhaust brake.

It warms up quite a bit faster, especially if it does the 1000 RPM idle.

Down sides, I think it uses more fuel.

From what I understand on pre-03 engines there is a pressure/temp sensor in the intake manifold that can require more frequent cleaning from soot (from exhaust blown back into the intake manifold during valve overlap when running the e-brake at idle).

 

I use mine to warm up all the time, warms up 10x faster!!

 

Works well for warming up the engine. Try it with and without a couple of mornings and you will see a huge difference in coolant temp.

 

The 7.3 PSI has an Exhaust Backpressure Valve (EBV) for exactly this purpose. Warmup is way faster. Uses way less fuel in the process. Unfortunately it isn't used as an exhaust brake, although some aftermarket people have produced a kit to do so.

The EVB is a pain on the 7.3 because it comes on automatically whenever the ECM thinks the engine is too cold. Like going down the highway. Fuel economy suffers. You can't shut it off. And it kills throttle response when the engine is cold.

I've got an exhaust brake for my Cummins. I haven't put it on yet. Spending too much time on this board teaching people about fuel pumps.

 

You can pretty much let it idle all day with the e-brake on.....

An e-brake is a definite must in a cold climate.....(like the West Coast )


I see you got a 12V.....its about time

 

I hope I don't get my butt kicked for hijacking this thread...but I'm purchasing a 4" Megamouth downpipe. I already know the answer performance-wise, but I have an exhaust brake from another truck that I wanted to put on my Cummins, its off a Deutz diesel and is air-powered. I think the inside diameter is about 3.5", so i know it will hurt performance. I have a bone stock engine though, so i really wouldn't make use of the full 4" of the Megamouth...I'm just getting the 4" to plan for the future ($25 extra and its already there for when I start bombing).

My real question is...how would the e-brake work if I were to install it at the bottom of the Megamouth? I wouldn't want to chop up the pipe, si it would be further from the engine. I'm sure it would still work fine for engine warmup, which is all that I could use it for right now (I still have an auto, and the mystery switch isn't working right), but I'm trying to find a Spicer 5-speed to swap in.

Would having the e-brake that far back cause problems one I have the manual tranny in and i want to take advantage of the e-brake for its intended purpose?

YEP!! Finally made the move doc
Cold you bet! She went down to 9 last night
Will see how time works out over the next couple of weeks but if I can get to it I will probably land the twins on and then the brake will be a door stop anyway. I never had one and just wasnt sure how they worked.

 

I beleive you are right here, don't have mine installed yey, but according to the manual, once coolant temp reaches 170 it will open up automatically

 

Congrats...Youll sleep better not worrying about fuel pressure and VP's....

now you have to worry about the KDP... (I still have to do mine)

Did you trade your 24V off??
