2015 truck turbo upgrade?

jensenrcng · Apr 6, 2016

I'm wanting a new turbo for my 2015. My truck has custom tunes, d******, cold air intake & 5" exhaust. I am not planning (diesel owners famous last words) on upgrading anything else. I want a little more HQ/TQ but really interested in getting the whistle back (former 6.0 guy). I have narrowed it down to the
Barder 6670R or the Midwest Streetmax R.
Morgan told me that they will make the same power without fuel upgrades... My question is Does anyone have either of these on their stock fueled trucks and if so what is your opinion and which one sounds better? Also If you have a video of you truck running these that would be cool. :shrug:
Thanks for any help guys.

the 6670R has a modified turbine so it is going to have the whistle. the streetmaxR is a stock turbine so it is going to sound the same as stock out the exhaust. the compressor wheels on both are very similar in size so they will have about the same noise out the intake (both louder than stock)

if you are not doing anymore upgrades than this, why not just do the streetmax? it is cheaper and will spool like stock.

unless of course the whistle is worth the extra dollars-i just don't see the point...

The Streetmax does have a pretty badass compressor sound to it. It definitely moves some air too... I'm running some new tunes from Midwest, and they have the Streetmax tuning nailed.

Sooner or later, I plan on upgrading to either the new Streetmax (65.5) or the 6670R. I think all of Morgan's current turbos also have the 360 degree thrust bearing upgrade, and that's a plus for longevity.

Regardless of which way you go, do yourself a favor and add a No Limit intake. I wasn't a believer until I tried one myself. I'd consider that a must-have supporting upgrade for the turbo.

Problem solved

Sooooooo let me get this straight... You want to spend anywhere from $2k-6k for whistle? I just don't see the point... if you're not upgrading fuel, and don't plan to, you're literally doing just that, spending thousands to get the same performance... I mean, to each their own and all...

Hell pay me the money and I'll ride along with you with a boatswains whistle, same thing...

Thanks guys, That info helps.

MAXXEDOUT : Will the No limit intake make a difference over an S&B?

jensenrcng · Apr 6, 2016

Notneb : Fortunately for you its not your $... But like the add says, I'm not planning to upgrade (Famous last words). But you know how us diesel owners are, Just want to do this one thing..... then well I might as well do this other because I can now and so on. Ask my wife about me keeping my 6.0 "stock". As for riding around with me thanks for the offer!

Yes it will, no limit is the best CAI you can buy IMO.

Cheap6.7 : I'm sure you're right, I will be back asking for more power sooner than later. LOL!!!

Yes, it will make a significant difference over the S&B, especially when you're running a bigger turbo. My only regret is not buying the No Limit intake a year ago haha.

Yes...with more fuel and another turbo upgrade, assuming you go with the StreetmaxR or have Neb ride around with you, hell yes.

Notneb · Apr 6, 2016

I went from an S&B to a No Limit S2, and yes, it's a noticeable difference. Of course I also did my piping when I went to the NLS2... might have contributed to the experience!

dsmracing1 · Apr 6, 2016

I'm running the streetmax 65.5 with Morgan's piping and the no limit intake and she's a beast! You won't be disappointed by any means. I'm keeping stock fuel for now too as I'm just wanting a reliable tow rig that keeps low EGTS. Definitely found it with this setup... Morgan's tuning is the chit, and his ability to help with any necessary issues is top notch!

Morgan's piping is designed around the no limit intake, so it goes together like peanut butter and jelly...

maxxedout · Apr 7, 2016

Not to derail the OP's thread, but I've been thinking about the piping kit as well... I'd love to get rid of all the factory garbage and ****** the CCV while I'm at it.

To the guys running the Midwest Diesel piping kit, what do you think? Pros/Cons?

Notneb · Apr 7, 2016

I'm running exactly that!
Pros: Cleans up the engine bay, works directly with the No Limit Intake, eliminates the factory plastic IC pipe, better flow and response.

Cons: It can be a pain in the butt to do yourself, enlist help.

Here's the link to my build thread if you want more in depth info: http://powerstrokearmy.com/forums/showthread.php?t=64954&page=4

When he does we got that covered! We gained 50hp over single pump tuning after adding dual pumps on a StreetMaxR truck.

650 on a 65.5 is very fun... 6670 can do over 700 though.
