I have decided to upgrade my trucks with Jake Brakes. I am also going with 4 inch exhaust SS 304t pipes to replace the 3 inch that is standard. We are also adding performance hydraulic clutches to our trucks. We are also increasing the Hp up to 425 with over 680 LBS of torque.

Later this year we are upgrading our manual transmissions to a cast iron housing 6 speed manual trany for better pulling performance.

It's going to cost about $ 9,500 per truck, but it is worth it. :wave:
 
Sounds nice, I don't know what jake brakes are but that probably means they're big truck high performance stuff. Why standard transmission? You ever thought about propane injection (i'm guessing diesel by the torque)? What make/model trucks?
 
They work great I have the banks exhaust brake and love it.
You can do alot more mods that dont cost a whole lot to get mo power.
I have a 2000 f350 with the 7.3 And I am putting out 500hp and close to 1200fp of torque and LOVE it.
To be honest I wouldnt waste money on bigger exhaust unless your EGTs are getting high. Spend money on a better air flow system then maybe exhaust if you need it.
My 2cents
 
Jim, I'm gonna have to give you an ear-full next time I see you...

It's CUMMINS No g!!!
 
Worse, they are Dodges...

Jake brakes are exhaust brakes. When you hear a truck coming down a hill when they get realy loud, it is teh Jake brake slowing it down.
 
I thought the Jake brake was when they cut the spark to certain cylinders.

In most places JB are not legal in town. Are you sure it's ok where your at?
 
If Jim is going to increase the performance to 600+ ft/lbs of torque it would be a must to have the bigger exhaust. Lower the EGT the better, especially towing a heavy trailer like he does.
Jim, another thing that you might want to think about are an exhaust temp, and a pyrometer gauge. It is nice to know that stuff while you are towing. Later on when you upgrade the transmissions, ATS makes a great aftermarket transmission that is made for pulling. One other thing Jim, if you decide to have the gauges installed tell whoever installs the pyrometer to install the pyro probe before the turbo and not on the exhaust side. If they install it on the exhaust side the temps that are read on the gauge could be up to a 400 degree difference (cooler) and not give you an accurate reading.
 
My 2005 Dodge Cummins Turbo Diesel Quadcab 2500 came with the factory 4" exhaust but A lot of guys told me that even though it is 4", it is still very restrictive so that is on the list of things to do later on, along with the programmer and different intake.
 
The exhaust on my truck is stock 4" its the only thing I havent changed/upgraded.
Even with 1200pounds of torque and 500 ponies My EGTs dont get above 1000 degrees towing 12,000 pounds. When you get above 1,100 degrees you need to worry at 1,300 degrees you start melting your turbine.
But then again Jim said upgrade to 4" exhaust, so go for it!!

Great point about before the turbo. I will see if it is possible for my year without breaking the bank. Thanks !

We are going to install a pyrometer gauge after the laws come out in 2010 for smoging the diesels. Thats another reason why we did not go with a 5 inch exhaust. Did not want to show too much after market stuff. 4 inch looks standard. 5 inch is obviously after market. Also, according to Banks and others in the field, HP is the key to the exhaust size. Most we talked to says 4 inch for my year with the HP we are thinking about ( around 400 HP) is plenty. I know we can get this truck up to 700+ HP with little cost, however I am not into that for a work truck.

We are looking at installing a bigger turbo within the same size housing ( New housing/ turbo of course, just looks standard) I wanted a twin turbo, however was advised against it due to the new smog laws coming out in 2010 for diesels. The law clearly states no after market equipment on your diesel that may produce more air pollution.

We are adding the Juice for added power, but what worries me currently, our standard " Extra HD Dodge Trany" which will not be able to handle the added HP with the trailer. This trany is clearly the weakest link and must be replaced soon before it breaks. We are thinking about the 2002/4 cast iron Dodge 6 speed trany. Nothing special is needed to install. Many like it for towing and has a good rep for pulling and not breaking.
