Hi everyone,
Ok trying to decide how to mod my 05 cummins 4spd auto, 4wd for more HP. Please remember that this truck is an all rounder and is use for daily driving, towing, and playing.
This what i got as far is profromance goes:
-Edge with attitude and juice module
-AirRad intake
-afe 4"exhaust
-High proformance tranny with clutch pack upgrades, Valve body, bearing Gear Train, Single disc torque convertor. Tranny is good for up to 450hp at the Rear Wheels

Option A- this easy to do as my tranny can handle it.
-Fass Fuel system 150 GPM
-Add Fuel pressure and Tranny temp gauges
- Single BD super B turbo
-Intercooler
-head Studs and Copper head gasket. (i dunno if this is need with just single turbo)
-75hp injectors
afe intake manifold (would this be something good to add. i know it increases airfolw)
-use current exhaust

option B, this is the crazy option, which i really want but don't know if i need.
-use curent Edge system Or change out to Smarty. I would really like to still use the Edge as it is very easy to change power levels.
-Fass Fuel System 150GPM
-BD Twin super B turbos
-Intercooler
-Head studs 12mm and Copper head gasket
-Camshaft, I don't know if this is needed or will orginal be good enought with twins.
-Dual CP3 Pumps
-75hp or 90hp Injectors? Please give some info on how it will affect my truck?
-Upgrade Tranny with multi disc torque converter, Bulit Input and output shafts.
- Run current 4" exhuast or Change out to dual 5". I am Also considering 8'' Dual Stacks but I am worried the noise will bud me as i talk on the phone alot while driving and I have a canopy that i use once and while.
-Add Fuel pressure and Tranny temp gauges

Any thoughts on these upgrades or am I just crazy. Do you guys think this is overdueing it for a daily driver. I already have dumped a ton of cash in this truck and and plan on keeping it forever.

Also what do you think I will make as far as HP is concerned. What would you say is a good target to set as far as how big on HP to go and still be reliable daily truck that will do everything.
Thanks, look forward for all the replys

I guess my question is since your trans is only built to 450hp to the ground, are you trying to be at a constant 450hp or is 450hp just for the dyno?

For that type of goal, a programmer, fuel pump, CP3 mod and intake & exhaust mods should get you right there.

Who's trans do you have? Why did you opt for a single disk when there are so many triples out there....not trying to flame, but you are going to eat that trans up as soon as you go big time. I do not see billet input/output on the trans, or the weak link the FLEX PLATE!!!

My daily driver is a 2005 with a HTT 64/12, glacier fuel system and built trans. I am running the Smarty only and have 536 daily HP available. You are going to find on the 2005 that 450HP is not hard to hit even on stock turbo, fuel and a moderate smarty program. If you are adding injectors I forsee you needing a cp3 upgrade to keep fuel to the rail.

Just my observations..... good luck.

For either of those options I would not get the intercooler. With 75-90 hp injectors dual cp3 pumps are also not needed. Just modify your stock cp3 with some of the kits out there.

Initially I would save your money on the camshaft and intercooler and put it into the trans because that will go first. If it were me, I would modify the options to...

Option A.
Fass
Fuel Pressure/tranny temp gauge
Turbo
afe intake
current exhaust
head studs, (not a must, but a good idea if you have the money)
tranny parts

Option B
Smarty
Fass
BD Twins
Studs and valve springs
90 hp injectors
cp3 upgrade, arson kit
5" exhaust
fuel pressure/trans gauge
Lots of transmission parts

Ultimately you have to ask yourself how much money you want to spend.

I like your suggestion of opt B. I am thinking by the time i add up upgrading my tranny and all opt b. with labour and parts maybe around 12 Grand CDN.
My Transmission Builder is Rat Transmission. Rob is the owner, and was previously working with BD Diesel. I blew my tranny almost one and half yr ago. Got it a new built tranny from Rob and didn't think i would need billet shafts and muilti disc convt as i was planning to just leave the truck as a work truck. it funny how you can change your mind! lol now it will cost me 3grand to upgrade the **** tranny..
anyways, I ended up getting my Fass system installed today by my mechanic, Andrew, at Jazzy Diesel. The system makes a little noise, but aleast i got more fuel pressure. And one more step forward in the right direction
Andrew had recomended that i just add a single ATS aroara 3000 turbo, upgrade cp3, intercooler, maybe smarty and leave the truck as is. He said that then i would not have to mess around with tranny or head studs etc.
My whole thing is I want to do it once and do it right. I do not want to have spend the money twice.

anyway happy turning everyone

theres no need for an intercooler or CP3 urpgrade at this point until you start moving lots more fuel(atleast smarty & stix).

I would get atleast 50hp injectors and maybe a cam for some better power throughout the band and keep it cool under the same turbo(even though that pushing it). You can get a single turbo with 50hp injectors and it would spool pretty nice just depending upon size. Also i like having an aftermarket air horn. my boost dropped showing an increase in efficiency, tiny improvemnt in milage and a better throttle response.

You already have a pressure box so you can run that with smarty. Your trans. seems pretty good but you never know since there is so much power delivered at low RPM and than being 4wd. The more you increase power the bigger chance you take.

For the time being get a smarty and see how much xtra power you really need over what you than have.

Redsmoke

Yeah i am running a edge juice with attitude box, can you run a smarty at the same time? what would you set the smarty at for everyday driving and what wwould set the edge at

Redsmoke

at the end of the day I want the best all round reliable truck who lots of power when i want it. the money don't matter but spending less would be better.

450 hp = Intake, guages, airdog or fass, smarty, stock cp3, stock turbo, stock sticks, smarty.
500 hp = Intake, guages, tranny, airdog, or fass, stock cp3, 62 turbo, 50 hp sticks, smarty. The upgraded cp3 will help but I still don't have one at 600 hp.

There are guys making more then 450 with just a smarty. Your list is way too long for what you want but it definatley won't hurt to be safe either.

Redsmoke

ya well then for 450hp i must be almost there: As I have intake, stock cp3, stock turbo, stock sticks, Edge juice with atitude, 4inch exhuast, Fass.
Brian are talking in RWHP???

Brian Lent

At the wheels you should be close. I dynoed with a friend of mine a few years ago aho had the juice hot. We put my smarty on his truck and he dynoed the exact same numbers as 10 min. prior with the edge. I think they make good power just run hotter. Only one way to find out though! Every truck is different.

Today was an interesting day.
I had gone in to BD diesel today to get some pricing and talk to the sales reps. They are very nice and know tons about the Cumminis motor. I had told him how i use my truck and he pointed me in the direction of a super B single turbo upgrade, Intercooler, Intake manifold. He quoted me 5100 bucks installed. he had mention for a daliy driver this would be the best as then you don't have to stud the head and do gaskets. and i would increase flow in the to motor and also some hp, with out touching my tranny. I was soo ready just to hand over the plastic and getter done! when i thought okay better be sure and sleep on it. Also get another quote from another shop i deal with, Jazzy diesel. The point is I need reliablility and need to do my upgrade wisely, as i don't wanna blow stuff up. and i don't wanna aim to big on the hp.
So then i confused myself by phone another well know shop in the area, PDR Diesel. They have a totally different view on diesel proformance compared to BD. The thing is Bd engineers there own products. PDR said upgrading a single turbo is a waste of money as your just making one turbo work harder and it would be more efficent to have twins. two turbos working less to achieve the same hp on regular driving. His price installed is about 5800 bucks just for stage 3 twins installed, which are on PDR website. Now BD wants 7500 for there twins installed. They apparently don't spool as fast as bd super B twin but maybe more reliable. That is PDR statement, Which confused the hell out of me. another thing is PDR Says do as many upgrades to achieve the HP you want. How ever i thought, in order to do you mods right you should do them in a way which could prevent any damage to other systems. for example, when you do twin, do your head studs, and copper gasket as the same time. then because your pushing too much power you need to upgrade the tranny. its almost preventative mantiance.
Now i am completely confused and don't know how to move forward. Can i please get some help here!!
I Just want to do this right the 1st time and be able to drive my truck for aleast another 300000km.

In the end you are going to have to make up your own mind. Each person you ask will have a different suggestion on set up.
I would say you first need to determine how you will drive your truck. DD, heavy towing, racing, etc. Then, decide how much power you want to make. Unless you say 800 (or more), take your number and increase it by 20-25%. This gives you room to grow.
Build your tranny and engine to handle the bigger number. (by engine I mean studs, springs, cam, head, etc.) For example, if you want to make 450 and have a DD, you don't need to fire ring the head or install a cam. For a 700hp+ sled-pulling, high-revving motor your "needs" change.

Talk with several different shops/builders. Find one that you feel comfortable with and who has a similar style to yours.

After you do that, if you can't decide on a set up, you can experiment. Get a used big single and see if that suits you. If not, sell it and try something else. You can try a Smarty and return it if it doesn't suit you, and so on. Drive a few trucks that have set-ups you are considering. At get-togethers you can usually at least get a ride. Ask the owner how he uses his truck and what he doesn't like about his set up.

Some generalizations:


You will eventually want more power than you now think you do.

The 05 has a good intercooler for 600hp (some run higher) as long as you don't have the plastic end caps.

Some mods are easier to do, and can be done later if the need/desire develops. An intercooler is one such mod.

Some mods are more difficult to do and need to be done as a group. Want big twins and 80psi boost? You can't really stud/ring later.

Big singles are more laggy (slow to spool) than smaller singles and aren't as streetable.

Twins (compound turbos) that make the same boost as a big single spool faster and are more streetable. They also cost more, and are more complex. More parts = more parts that can break.

Going into the motor once is a lot less expensive than multiple times. (If you are paying for work.) So, if you're doing injectors and debating studs - do them at the same time. You don't have to pull the head or change the head gasket to install studs. You do have to pull injectors to install studs.

Going into/rebuilding the transmission... see motor above.

The higher the power and the more you use it, the more stuff breaks. There are those who run 5-600+hp for long periods of time without problems. There are also those with stock trucks that break. However, the fact remains.

You will eventually want more power than you now think you do.

Good luck, and let us know what you decide.

^Great post. You say you dont want to aim to big on the horsepower but that can be taken so many ways. What type of hp are we talking about here? You say it is for all around use, towing daily driving, ext. How much weight are you towing? You live at altitude?

rburm

Hey Redsmoke, i live in Richmond, and have an 07 with all the mods done that you are looking into. would be happy to take you for a ride at some point and discuss this stuff...ive gone through the expensive learning curve and hey if i can help a fellow gear head out, why not.
