So as short and sweet as I can make it, which won’t be the case but.....Truck in sig. Recently installed the BBIs, and ran it down to the Scheid X couple weeks ago. Pulled a friend’s 32’ 5th wheel which was first towing test after injectors. Pulled it respectably, and put it on the dyno there. Put up a 565/1050. SO, after talking with some of the sales reps there about what I need to do to get in the 600-650 range, seems the consensus was I needed more cp3, and maybe more air. On the air side, I’d prefer to stay away from compounds, because as much as I like the idea of them, I ultimately want to eventually mount a Pacbrake or similar exhaust brake, and I think compounds would make it difficult space wise. After talking to reps there, the turbo options that were recommended were the II Silver Bullet 63/74, or the ATS Aurora 4K. Any other suggestions that would get me into that hp range, and keep my egts manageable for towing, would be welcome. As for the cp3, I’m leaning towards going with duals there. Seems price wise to be close enough that a guy might as well go duals vs stroker, and at least that way you have backup in the case of failure of one pump. Maybe my thinking is wrong on that though. If there’s any opinions on that, I welcome them too. I’ll be pulling the motor this winter to replace a leaking oil pan gasket, and engine compartment tidy up. So I’m hoping to have a bunch of parts ready to go in at same time when it’s out in the wide open

My opinion for simplicity would be 2nd gen swap s363 or s362sxe with a stroker. Simple is better. You're not wrong on the duals option but murphys law applies here. Sxe turbos will perform as well if not better than brand name turbos with a lot less cost.

I agree with the sxe turbos. You can hit your goal with a stock CP3. I got 624HP on a dyno with a stock CP3. If you think you might want a little more power down the road, then go with 363, otherwise i would go with the 362.

On the 'air' side of things, compounds themselves take up some room for sure but the exhaust brake is an 'inline mount' under the truck. With a single turbo you can use the 'direct mount' off of the turbo.

A modded HE351 will get you to that hp goal as well. That or a 2g swap with a S363. I wouldnt expect a stock cp3 to make north of 600 but there are quite a few that do but I would not expect it to make that power.

 

[RamThisCummins]

I would get a cp3, if yours can't keep up, draining rail.

That turbo will support 700+. But if you haven't gotten a new tune for the injectors I would do that first.

So your opinion is my cp3 is my limiting factor at this point? I do have an oem 2nd gen manifold along with a 63/67 modded 351 from Taterbuilt. Which he also mentioned should be good for 700hp. But I almost find it hard to believe given that I have the equivalent of 90hp injectors that netted me 565. But maybe you had them dialed back to the point that with more cp3 I would see a bigger gain out of them. I just really doubt I’d see 700 from that turbo by itself out of injectors I know are capable of 700 numbers.

Yeah, Phil did send me new tunes for those injectors, but they are dialed back though I’m not sure to what extent, to take stock cp3 into consideration.

I agree. And I did consider the inline mount, but I also know that the farther you mount it back from turbo, the less effective it is. So ideally, I’d like to keep it close. Which raises the question if when adding an exhaust brake, which turbo mount config is the best? 3rd gen, 2nd gen down, or 2nd gen flipped up?

Also, to those who suggested the SXE line, that is also one of the options I had in the back of my mind. Seems a lot of guys are going that route nowadays. And if they can be had for a better price for a quality turbo, it’s definitely something I’d have to look at

I would turn it up until it starts dropping rail, then upgrade the cp3. If you aren't making enough boost plug the waste gate tube lol.

 

[Broaner]

Realistically both cp3 and turbo are probably limiting you. You might gain 40hp from each but together you could pick up 150hp. All hypothetical numbers. Just making a point.

Yes the SXE is a great bang for the buck. And a t4 2nd gen swap will really do you some good. Its just the way things are supposed to be if ya know what I mean.

I had the 'Direct mount' originally & went to the 'Inline mount' when I went to compounds. My experience with the same truck, there is no difference between the two set-ups in performance, no lag. :confused013:

Good point for sure. Interesting that you mention T4 second gen manifold. What would that do vs T3? Obviously larger ports but if I did indeed go with something like a 63sxe would I not need an adapter because that comes with a T3 flange, or can you order it with T3 or T4?

Not sure how to turn it up other than tuning, maybe there’s a way I guess. But just to MAYBE gain a little from turning that up I don’t think is worry the money to get another new set of tunes. Once I get another cp3 or turbo or something significant I’ll look at new tunes but not when I just got a set for my current mods

You can have the tunes you just ordered revised if they are holding rail pressure the duration can be stretched out more.

 

[Flyingfinn73]

Ahh ok. Thanks. Didn’t know that was the case. Figured had to pay for new tunes any time you change em . I’ll do some testing look at commanded vs actual RP and let you know. Thanks again

Some will charge you, some won't.

Well you have your answer to that question about Anarchy straight from Phil. And so do I! I paid for the tune change when I put in bigger injectors, but the way I understood his comment, is that set of tunes can be tweaked if need be without extra charge. Though I’m sure there’s a limit of how much time he’ll spend tweaking without getting reimbursed again!

Can be ordered with T4
