For 550 plus horsepower, you don't need much.. Just a nice combination.. If you do an II 62-14, DDP 90hp injectors, and good programming you'll be there.. You can pull a trailer great.. Spools great.. EGT's are fine.. You don't even have to run a lift pump.. I've already done it.. Mine made 543 uncorrected dyno jet hp with the old smarty tune.. It's much stronger now with the new tune..

 

Stock CP3 and injectors. 573hp. Read my sig.




and I don't need no stinkin' smarty...

 

I hit 522 stock fuel system, smarty, dr p predator, SPS62.

534 with beta smarty

With my new mods (injectors, cp3) I still havent gotten any dyno time...but I do still pull 21+mpg with the smarty on!! New PB of 23.3 last tank!!

 

Is is better to stack another box with the Smarty or put injectors in with Smarty??

 

With my current setup I feel like im right on the border at 500hp. Just installed the crazy larry yesterday. That program is sick. I turned my edge down to Level 1. Dont wanna tear it up too bad. What do u guys think? 500hp yet?

 

Smarty is an option, but it's not the best for everyone. I had one to test for a week and it was a dog on my truck. It made less power than the Hot Juice. There are a lot of trucks in the power range you are after running other stuff. There are also a lot of trucks in the range that do run the Smarty.

Some guys are getting 600hp on a stock cp3 - but very few. You can break 500hp with a stock cp3 for sure. But remember, it's not all about peak numbers. When I did the cp3 what it got me was more low end power, and the top end power held on longer. Also, if you were to go with a pump from Floor It, a stage 1 will get you 600hp and save you $500 to spend elsewhere.
A lift pump upgrade is needed for sure though.

So what you need to do it right....
A controller - Juice, TST, Quad, etc.
Some pressure - via a controller or a pressure box - xzt, mp-8, VA, etc.
Turbo
Lift Pump
Cp3 - ? - depends on how much hp/fueling
Downloader - Smarty, BDDL, Predator, etc. OR Injectors
Tranny work - can't forget this step!

You can hit 600 with a downloader and skip the controller in the mix, but you lose some adjustability that way.

I should be well over 600hp with my set up, but there is something goofy going on with my truck (electronically) that is currently being worked out.

 

I managed 632 with a stock cp3, but it definately was taxed to the max. Totally ran out of ruel in the rail well before it hit its maximum power. It is much stronger now that I have the stage 2 cp3 in there.

Wher would I be at with a Smarty, CP-3 and injectors? And do I need a pressure box as well?

 

Depends on the injectors. DDP 90s or Flux 2s and I would think 525 area. Pressure might get you another 20-50hp. You could go big onthe injectors and gain more. Remember, with what you listed, you will need a lift pump and minimum a TC/VB for the tranny.

 

How do the DDP's and Flux injectors compare? I like the idea of being in the 550 range with the pressure box. I already plan on changing out all the necessary components for the tranny. Another question, with twins is it a good idea to run a 5" exhaust back?

 

I just have to throw something in here.. I would not run a pressure box.. If you're going for max power on a race rig, yes. Otherwise, no.. I had no lift pump for over 20,000 miles on my 05 dually and it ran 13.0's at 8,040 pounds with a single 62 and DDP90's.. That was with no torque converter lockup switch. By the calculator, that's over 600 rwhp. The new trucks have a much better fuel supply than those a few years ago. I used the scary larry program and cracked an injector. It did make great power..I'm now staying away from pressure.. It's just not worth it.. DDP90's and a stock CP3 can take you over 600hp with no lift pump.. Keep it simple to start with.. It doesn't take much.. I'm only sharing the exact combination I have a lot of experience with. As posted above, you do need to start with atleast a torque converter and a shift kit. 5'' exhaust isn't necessary.. Replace the factory muffler and converter with an aftermarket straight through design, and you'll be set..

 

Were your numbers achieved with everything in your sig? I think some trucks respond differently or maybe its just the dyno. I put down 468/923 uncorrected on a dynojet with just the smarty on 9 and 5" exhaust. I think if i added a modified cp-3 and flux 2's id be in the upper 500's. I dont know though, i could be wrong.

 

As far as needing a lift pump, depends on how long you want your cp3 to last. Fuel has 3 options once it get to the cp3. Feeding the rail, cooling and lubricating the pump, bypass. The only way fuel is doing all three is if you have an abundance. If you have fueling demands that require all the fuel being delivered to the cp3 to be sent to the rail, guess what, no cooling and lubrication. A lift pump is a whole lot cheaper than a new cp3.

As far as pressure, you need two things to do it safely - a rail pressure gauge and a 2 micron filter set up. If you have those two things with ADJUSTABLE pressure, there is absolutely no reason not to run pressure. No gauge and no way to control the amount of pressure - that's where people run into problems.

 

Yes, but again, I'm having some problems. I put down 502 with the Juice, mp8, and turbo. I had the cp3, but probably wasn't helping peak numbers at that point. I was getting it because mine was leaking and would have eventually bought one anyway.
Yes, different trucks respond differently. My truck did not like the Smarty. It made considerably less power than the Hot Juice.
As far as my estimate of the 525hp. I figured 275 + 170 + 90-100 is 535-545, but that's if you get exactly those numbers. So you got around 190-195 out of the Smarty - that's better than most. I didn't dyno with the Smarty on my truck but I would guess it was worth 120 at the most on mine.

 

Yep, Stays on 9 and never moves.. Once you go big you can't go back to the little numbers!!! And she's all stock.. Like posted above.. Be smart.. The hardest I have been on my truck was at dyno days. Other than that I drive it very smart try to keep the tranny torque converter locked up and that's about it.. I honestly think the tranny's are built stronger than what they are made out to be there is just guys out there with a chip doing 0-60 launches at every stoplight! Making a bad name for them.. I tow extensively and heavy and don't have any troubles no slipping, suring or anyting.. So far so good!!! Now just to get to that 700 mark!!! On a stock tranny!!
