To pressurize or not

[Cattletrkr]

I've been toying with the idea of replacing my Juice with an EZ or other pressure box. Nothing wrong with the Juice, I just haven't done any mods lately. This has kinda got me thinking. Which is worse in term of engine wear? Timing/duration vs pressure. I've got the rokktech sensor fully advanced now and I don't think I have an "overly advanced" issue. like I said, I'm just thinkin'.



Before anyone says it, yes stacking was most definently my first thought. But I don't want to buy a new turbo along with the EZ. I can get a new EZ for relatively cheap... my tire guy will sell me one at cost or nearly so.

timing and duration is worse. go with a ez or a predator box... ... ... .

why do you say timing and duration is worse?

im just curious. i have a Van Aaken C3. 2 and it only does duration... .

im looking into a larger turbo as well.

Thanks DP.



In another thread about the modded CP3's you mentioned something about the "benefits of pressure". Were you referring to super-duper pressure like the modded pumps, or plain old boxes as well. What benefits, other than the obvious power/mileage?

I would also be interested to hear why. It has been my impression that increasing rail pressure was the least desirable way to go because of potential injector problems. I was seriously considering a Van Aaken to avoid increasing pressure.



Whats the story?

ok guys this is deep subject. duration does not modifie timing which will raise egt's unnessisarly, also more duration will lower pressure, which decreases atomization, and a clean powerfull burn. and it increases black smoke a lot. the bad part of this is it's shoving so much fuel in at one time, with no timing advance, and no pressure increase to burn it properly. the resultwith alot of diration is cylinderwash--beacuse you are forcing alot of fule in at a givin time, that is made to opperate under extream psi to burn the fuel, but now is not. dont get me wrong it's not somthing thats happens over night, it will take years ansyears of someone being hard on the duration only box for it to affect anything, because the cummins is so tough. but in answer to your question you see why i chose duration as the biggest harm, if it's alone, but also timing can be as well if there is too much you can blow your motor quick. but you can't go wrong with pressure our engines are designed for high pressure---it burnes cleaner, offers more power,and will coplement high timing and duration boxes for an awsome stack. bosch has all the components ( except for the relief valve) tested for at least 28-30+thousand psi, so i think we will be just fine---thats where my truck runs around at. :-laf hop this helps as there is much involved with this subject. Oo.

van aaken makes agreat box, and a turbo will make it even better

the bennifits are many, a clenner burn will make most of your engine cleaner and wont contaminat your oil as much, plus pressure will make sure your injectors stay self efficient and clean. Oo.

i can put together a simple pressure and duration combo that you and your truck will love, that works Oo.

 

[JHardwick]

I ran an EZ for over 150,000 miles, I now have 210,000 miles and still running OE injectors.

Thanks, I'm doing this low budget. It is for my 100k mile '03 and I think will look for a used EZ

the plan is twins and 50HP injectors... .



and a new clutch... Oo.

but i dont get paid enough, and i dont like running up my credit card. i like it paid off, or able to be paid off next pay day without having to eat noodles for two weeks... lol

:-laf I had a truck come in Friday,mil light on and a customer that swore he never had a box or programer on it. He had heard a loud pop that scared him followed by massive smoke and the dreaded mil light on. High rail pressure code... . After I suggested that some one had run a box on it he came clean..... A quad box was on for 3 days and had popped the valve repeatedly. The freeze frame tells the story. 29,8xxpsi is not good on a stock set-up

that proves that you can see a plug box in if a component fails.

Pressure in moderation is good. Pressure with timing and duration is even better. The added pressure with a timing and duration box like the TST helps keep the pressure in the rail high enough to maintain good atomization unless you get crazy on the settings.



There have been enough posts on here that would prove that running a pressure box on kill all the time as the only means of added HP is very hard on injectors. I've seen pictures of injectors that were damaged by running high pressure all the time.



I guess that is the benefit of the modded CP3. High volume at the right pressure to keep things running in the sweet spot.



I just wish we could get this figured out. By the time we save for the latest best mod, someone comes up with another better, safer way to add ponies. Will it ever end?

 

[Cattletrkr]

Will it ever end?

I hope not.



I've been looking at a couple EZ's on Ebay. If I could get one cheap enough I might stack 'em. I really don't think my truck would like that, but I know I would... for a little while. I'm sure I have enough self control to not break something. :-laf Yeah, don't we all.

 

[RDyson]

You can sure tell the difference a little pressure makes. I still have the stock 47re and have ran the TST/EZ stack for a year. I run it on 3/3 & 1 most of the time. Heck, it takes that on my SO just to get where you guys are stock! I can turn it up a little when the TC is locked and man it will fly.



I'm upgrading my transmission next summer and then I will be able to play a little more. Can't wait. :-laf
