Twin Turbo's for the Eth andall other 24 valvers

[therabbittree]

hey bd makes a 4" under the truck exhaust brake too. . not just pac brake. . i don't thing the bd needs the compressed air?. . a 5" would be sweet though id like to run a aircompressor any how... to power airhorns and bags too. . my truck did not come with ac any how so room is there ...

I was just stating that Pac-Brake does make a 4" and 5" but they need to be run on compressed air. The only reason I said this is that it sounded like K_Arts wanted to stick with Pac-Brake stuff. I know BD makes an excellent 4" brake. I also believe that it uses vacuum to actuate it. I don't know if it is turbo mount or not. Although, I don't think so. I know that the larger Pac's are not turbo mount. But where would you mount a brake on a twin toobo truck anyway? I am interested in this as I have on board air and could run the bigger brakes. Oh what fun!

You wouldn't haven to have any part numbers would you? I called pacbrake and talked to them about getting a bigger brake. . cause I wanted to go with a full 4" exhaust and they told me that they currently don't sell anything for the Dodge bigger then 3". Even though mine is a turbo mount, I would have no problem putting the brake down on the exhaust pipe somewhere and compressing it. As long as I can still use it. If a brake will not work on a twin setup, I would be really interested in just trading my turbo in for an HX-40 and finding a 4" turbo mount replacement that I can put on my pacbrake... if possible. Any ideas?

Thanks for the help.

Kevin, I don't know if this will help you but here's what I know... The 4" BD brake is run on vacuum, not compressed air. The brake is located in a straight section of the pipe, not a turbo mount. I think that you would be better off selling the pac brake and getting a 4" BD rather than attempting to use a 3" brake in a 4" exhaust (if I was reading your post correctly). I would have to wonder how the restriction, from 4" to 3", would perform in the area of spool up and egt. reduction, in regards to the use of a 3" pac brake on a 4" exhaust. If I misread your last post, I apologize in advance. Hope this helps. I can tell you that you would not be disappointed in the performance of the 4" BD. It is a little on the "pricey" side.

I know its a concern, the e brakes will worl with twins also the 5 " exhaust is not a must you can run a 4" it will cause a little back pressure but it should be fine I have been swamped this week so I did't get anything done on the system but rest assured we are getting closer the machine work is what is a pain in my butt anyway I hope that helps kev still not sure why you want to slow down #ad

Hey Wiz, I would be interested in your setup for a twelve valver. I already have an H2E-17cm turbo on the truck with an HX35-16cm sitting on the shelf. I could use all the plumbing pieces though.

bid _dq hey I need to know what if any changes to your RPM is it still factory or have you cranked it up I don't think either of those turbos will work but we will run the formula when I get to my office this morning I will post a check list you and everyone else who is interested will need to answer the questions before I can begine to configure your system the 24 valvers are all going to be pretty close but the 12 valvers on the other hand thats a whole different world check this post later today I will also post the checklist seperatly

twin turbo's questionaire
1)Cubid inch displacement?
2)How Much boost wanted?
3)Intercooled or not?
4)what elevation are you running in?
5)highest ambient temp?
6)RPM you will be running
answer these questions to the best of your knowledge then email them to me or post them WIZ1

wiz,

Don't you also need the max engine speed to combine with boost to calculate the mass flow rate of air through the engine. I realize that all 24 valvers will be the same,but some 12 valvers are turning 2800 while others are capable of 3800. That should make a BIG difference in turbo choices if you are going to keep them as efficient as possible. I'm sure it was just an oversight because you alluded to it earlier.

You know... its that same ole story again. . about towing heavy weight within the mountains... LOL

Cause we all know how bad it sucks pulling weight in the mountains with and Auto.

we can make the power but anything after the engine I can't be responsible for #ad

the transmission will be the next weak link when you put your foot on the go peddle there will be no turbo lag so all that power and torque will be hitting the trans all at once so look out baby there may be parts flying #ad
