I really like Nick's presentation. Really good ability to publicly speak and really easy to understand. This is a great, thorough explanation of a compound kit...of any size.
I'm thinking that they should make a diesel insights video on choosing the proper torque converter stall and how the proper or incorrect converter can affect driving and/or performance.
Great idea!
Good info. i ran a S483/96/1.32 over a 63/68/14 on a 04.5 CR with alot of fuel. Spooled extremely fast and was very clean on street tune. When on the Hot tune truck made just shy of 1,000whp and we limited it with the gate to 85-90 psi. More then that drive pressure would rocket.
Always love how relaxed and none scripted looking your vids come out on top of great info and actually trying to teach people do's and don'ts, good and bad. Keep up the good work guys 🤘
Great video like always from y’all!!
this is the first compound turbo vidy that makes sense awesome info
Late to the game, new to the channel. Great video, Nick. I appreciate all your insights. I'm working on a plan for my build, before I go headlong into spending thousands and thousands of dollars yet again on my truck. I Already have a built trans and 625 ARP's, a Mishimoto IC, and an "Illegal" H&S Black Max on my 2010 6.7, so my foundation is solid.
Thanks Nick. That's good info among a lot of bad.
Great video and explanation, thanks
Always good advise I appreciate you guys and love your setup I have in my 5.9
Appreciate that
Very Well Explained
👍👍
And subscribed
Thanks
Any chance you could do the same video but talk more about what you would need to adjust for the low end torque and towing end of the spectrum? I'd love to get a real quick spool down low at 12-1500 rpm, not too worried about the top end but still need it of course.
Can you cover one for racing sizes that you guys have tested and found what works be really helpful
Thanks, spoken in a way that people easily understand. All the way up to the headstud thing. Then not what I have found to be reality. The truth I found: After market headbolts break, intercoolers need special made high pressure exchangers. Good luck out there!
Nick is a chu chu train at 1:13 sec in to the video.
Keep it up great video
This video was geared towards trucks but I’m looking to compound my 21 Hyundai Sonata 1.6T do you have any insights for fitment or do you know what may fit that car?
Any tips for a 1.6 idi. I was thinking a gt17 or something about that size and then mabye a gt25 or t3/t4 for the larger turbo... any tips would be nice... the idea being it will spool instantly, and hopefully with the larger turbo it will keep making driveable power to redline. Revs to 5000 hoping to keep power to 4500. And not hoping for much power.
Hi nick would you recommend a twin turbo kit for a 3126B cat engine ? It's mainly used for towing my 42' fifth wheel rv . Thanks Rod
Building a fule restricted 5.9VE (91.5IC)looking for 3-350hp@ 2000rpm w/stock "2500"(actualy 2000 through 2350) rpm gov .
What do you think of g25-550 HP and s362sxe LP for this project?
Context is king
3 9l 4bt @3500 is the same air flow as a 6bt @2500.
With that said, my thought is a 350 horsepower compound setup for 4bt should be ideal on a low rpm 350 hp 6bt
My left ear really loves this video.
What about your Right Ear ?
HI Nick- Jess here from Australia- Have to say your clear and concise videos are excellent, lots of good tech information delivered in a way that is easy to assimilate ... my question is a little off topic for your every day engines- I am building up a Mitsubishi Canter 4x4 I am wanting to do a compound setup -the engine is a 4M50 (4.9L 4cyl) my Factory turbo is TD04HL = 45.6mm exducer, 52.0mm inducer- I am wondering what you would recommend as a second turbo I am struggling to find the right information to match them up... Thanks in advance.. Jess
seems the Bot has blocked the numbers for engine its a Mitsubishi 4.9 litre 4m50 the factory turbo is a TD04 HL with 45.6mm exducer and 52.0mm inducer
now that the baby colorado duramax has been out for a while and the 3L duramax is coming out is there going to be a sizing guide for that scale of system looking for the 300-500hp window?
Awesome video once again. What sort of drive pressure compared to boost would you consider typical to see on a compound set up
It's not unusual to see 1:1 drive pressure below ~2750 RPM climbing past that, may peak 1.5-1.6:1 towards 3500 RPM. It really depends on RPM, load, and turbo sizing.
Upgrade smaller turbo turbine wheel
Wow Nick great video and sales. Appreciate your insight. Pretty obvious from your presentation you have immense time and knowledge in R&D. I’m knew to diesel performance but not building high HP motors. I kept thinking why would you upgrade the small turbo over adding a compound. Will be talking to you soon for my motor upgrades. Looking for power in a f550 2nd gen Cummins. Heavy truck for work and don’t want to destroy mpg. How can I get in touch with you?
You can talk to one of our knowledgeable reps. 815-568-7920. Thanks
I'm wanting to do my s366 Street billet with an s480 im thinking it would do fine for 800hp
I'm currently running a 63/68/14 T3 turbo, would it he a good combination for a S475 T6 1.15?
Great video, love the explanation. Just curious - planning to eventually run a Stealth 64 with the 67’s hot side under an Aggressor 88 on an 04.5 Cummins, and I’m wondering what the maximum RPM is that could be sustained for a prolonged period (up to 5 minutes) without putting the valley turbo in danger?
Give us a call, Robert! 815-568-7920
what about the hotside of lp turbo 171702 borg should i be running the biggest a/r i can get since turbo lag is not a consideration
I got a s400 sitting at the shop. Could I just add it to my stock turbo on my 05 6.0 ? It's got head studs with a 100 hp tuner stock injectors.
What compound kit would you recommend for lly stage 3 trans 650 build, 15% injectors mild engine internals ARP everything, new stock turbo mild pulling tunes. Its for a daily work truck about 200 miles a day, low to high elevations. Only pulling about 8-10000lbs. I'm looking for reliability low egts for pulling weight up hills and taking stress out of the system. I'm thinking stocker 475 or 471 kits?
Give us a call, 815-568-7920.
Currently Running lmm with s480 over stock kit 60% overs 10mm pump, built short block, Been this way for couple years love it. Looking to up the game.
Would stealth 67g2 with 64 compressor / s480 get me fuel issues? Upgrade to 100% overs? Dual duelers or Single 12mm? And what would probable power output be?
With that combo you could likely jump to 100% overs and a 12mm pump (or dual Cp3's) and make 1,000 HP. It really depends how you use the truck and what you want to accomplish with it.
I am curious about running a larger secondary and adding an external waste gate to relieve exhaust pressure. Is this s good way to go?
I have a vp44, sxe 362/70 - 472/110
I wouldn't go any bigger with your secondary. If anything just do an external waste gate on the set up you have now if there's a real pressure issue. The trouble with the vp44 is that you really aren't going to make more than 600hp reliably, and the 62/72 setup you have is good for 650-700. So going larger on the secondary is going to gain you pretty much nothing, just loss of money on a turbo you don't need.
Great video! Here’s a question: ‘05 Ram, 5.9l, Manual Trans, Stock CP3, BBI 0.5 (60hp), Smarty S06……what if I want to use the stock turbo for the fastest spooling daily drive/tow setup on the road and don’t even care about saying I can make 700hp? What about downsizing the primary to a smaller T6? BorgWarner S400 SX-E? Garrett GtX470? What would you recommend and how would you size it? THANKS for reading the long comment!
Hey Andrew, give us a call. Way easier to talk about over the phone. 815-568-7920, thanks!
Think I’m going with S471 T6 71/96 1.15 A/R
@duramaxtuner you guys are freaking awesome. I'm guessing my PPEI autocal is locked, id love to try your tunes!
Thanks! Most reputable tuners will unlock your AutoCal for free.
So my lmm I bought came with a s475 over a danville 68mm drop in. Engine had cracked piston and I'm rebuilding. But I have been told the 475 was too small for the 68 and I needed a 483 or bigger. So I'm looking at a bullseye 488. Thoughts?
Give us a call, 815-568-7920.
I’m looking at building a compound setup on a 06 cummins with a 363/74/.91 sxe on the manifold would a s488 be too big for a primary or would that be a good setup?
The s488 should be a good match.
Got a 2000 Cummins 6 speed manual, has 200hp injectors, headstuds, Ejwa, airdog 100 and some other small things done, I have a 63/68/.70 turbo on now and it runs pretty decent. I’ve toyed with the idea to eventually run compounds. I don’t tow with the truck at all I just play with it. What would be a good turbo to pair with what I got? Minimal lag and decent driving manners, any thoughts? Thanks!
An s480 should be a solid match with that setup.
So what if you were to stack an S475 or S480 over one of the stealth series turbos say a 67mm on an LLY? Truck is only driven on weekends with some spirited driving but gets used as a daily driver?
It will be a badass kit. Stick with the s480 at least, maybe think about an s488.
I'm looking for some advice on adding a compound kit on a 2015 Ford 6.7
While we have not dove into that specifically I love the idea.
I have a 12 valve with a hx35 hx55 compound setup. It performs absolutely perfect, but I’m curious to your thoughts on a better replacement for the hx35 Because it’s such old technology. Is there a better option for a manifold charger in this setup?
If anything you may tweak with your wastegate opening/arm length preload to get the best 'handoff' between the two turbos, but in reality the HX-35 is going to be tough to beat in that application especially at power levels below 650rwhp.
That’s what I thought. I have the gate set at 25lbs as is.
At 45lbs total boost I have 14.5 intermediate boost.
Stock fueling minus timing.
Was wondering if I should go 475 or 480 1.15 over stock for strictly pulling decently heavy. Just want the engine to be safe and cool which one would be better since price is similar and what are issues going with the 80 instead of the 75. Thanks
475 is likely going to map out for better drive-ability. The s480 will perform better at peak load but likely will have higher drive:boost pressure ratios on average.
Okay Nick! I've got an 08 6.7 48re swapped cummins with efi from Firepunk made 733whp on a single 369sxe on a 3rd gen manifold swap, question is will this be sufficient to run an s488 or 491
Truck is studded with 6500rpm valvsprings
10mm exergy stroker
60 percent overs
Fass lift pump
Intank sump etc
*end goal of 1500hp*
Not opposed to upgrading fuel again
Yes! We have had several customers run similar compound setups. You likely are going to want to upgrade your Cp3 and Injectors to get peak power.
Hi Nick, will the "average" stock diesel turbocharger exhaust side be able to flow well enough to drive the second bigger turbo (if sized correctly) without any modifications?
Good question. The short answer is yes.
Cool, thank you
I’ve been poking around the idea of running a stealth 64 with a s488 on my 2015 lml building a solid 7-800hp tow rig and maybe 9-1000hp on a hot tune. Would that be a good matchup?
I’m running an s480 over a s364.5 sxe in the valley on my 03 lb7 and it tows like a dream
I have a 2007.5 Cummins 6.7L.
Head studs
20% over on injections
64 mm phatshaft turbo
Built transmission
Larger intake manifold
Larger inter cool
My EGTs are manageable but I have been considering a larger single or compounds to keep them even lower. I am a idle to 3200 rpm kinda heavy tower. What are your thoughts and recommendations.
Nothing beats a compound setup. That being said, they come with a price. If you are looking for a turbo upgrade, the Stealth 64 is a better match for your current setup. The 67 will give you room to grow.
When going to a compound, is swapping the stocker for a 63mm a bad idea if the primary is a 80mm? I'm looking at a compound kit and the 63mm comes with it.
John Davis you really want to focus on the turbine sizing if you’re planning to run the kit hard. Think small compressor (love the 63s with 480) and make sure it’s got LLY vanes or large like in our Stealth lineup. Avoid LBZ and LMM exhaust housings. Unless you’re under 700rwhp, then you’re not pushing the kit hard enough matter ;)
Hey , Nick! I have your stealth 64 turbo on my 06 5.9 and I have been running into some turbo surge problems. Any ideas for a solution? Will this compound kit help, or are you able to change out turbo wheel? I’m at a loss and any help would be great, thanks.
give us a call so we can learn a little more about your issue and in turn, give some helpful feedback. 815-568-7920
@@Duramaxtuner ok, thank you.
Hey so to start out I’m a missionary in Haiti and have a 2011 Isuzu Dmax which is a foreign country built truck not sold in the US. But it is super ridiculously slow and we get into some bad situations sometimes down here especially lately where I want to get the heck out of there as quick as possible. That being said it has a 4 cylinder 2.5l turbo diesel with a super tiny turbo on it and the engine is fully mechanical no computer to change anything. I’ve increased the fuel flow of my injector pump slightly and that already made a difference but would like to pick up some more if possible. Should I look into a compound setup so it runs cooler in such hot temps here or am I better off just going with a little larger single turbo or even a factory same size just with a line to the wastegate and throwing a T in it just for some small gains. Again not looking to blow the engine up but don’t love how slow it is. Also on a tight tight budget haha 😂
With a tight budget, we'd say go larger single charger.
I’m looking to take my lbz to the limit of the bottom end or around the 700 hp Mark I don’t tow often so I was thinking of getting a stealth 67, but after watching I’m questioning if I should run twins instead? Thoughts
It all comes down to how you use the truck. If you tow often and heavy, you can't beat twins. The big benefit of the single is obviously cost but it also allows you to build your truck over time. You could always run the 67G2 now, then add an s488 down the road.
Duramaxtuner thank you for the suggestion, you guys will be getting a call soon!
I bought a LML Stealth 64 from you for replacing factory one
thinking for turbo compound kit
should I get 1.32 t6 or 1.15 t6? thanks
The 1.32 works great on that application. We've run the 1.15, it balances the output but honestly probably isn't worth the cash.
@@nickpriegnitz5895 Thanks
I am currently running a s476 sx-e 1.15 AR over a s361 sx-3 .83 AR (non gated) with 30% over injectors. On stock tune it builds boost quick and tows nicely with egt's maintaing sub 1100f however I am concerned if I run it in tune 5 (650HP) my drive pressures may be too high due to the restrictive .83 housing. I am planning on adding an external gate to relieve drive pressure from the secondary turbo and feed into the primary but am unsure what # spring to start with. What would you recommend? Do you think it is even necessary with my injector size and HP?
@hallasnackbar1865 It really depends on the boost pressure you plan on running along with the wastegate actuator you plan on running. If you let me know what those are I can probably help you figure out what will work best.
@@Duramaxtuner I did not have a specific boost pressure in mind, I just want to keep both turbos in their optimal efficiency range and avoid over driving and damaging the smaller turbo. I have 30% over injectors and a 5 position switch with tune 5 maxing out at about 650 HP. I have not used tune 4 or 5 since switching to the smaller exhaust housings . I don't race the truck and rarely if ever run past the 3.25k rpm factory redline. The truck had T4 .91 and T6 1.58 housings before and it made 650HP at 3500 rpm but was really laggy sub 2200 rpm and the power was unusable for towing.
@@hallasnackbar1865 You will want to base your turbo's boost pressure off of the efficiency range of the compressor map for that turbo (if you have access to one). If you are exceeding, or at the limits of, the efficiency range then executing your plan to re-route the waste gas into the secondary turbo wouldn't be a bad idea.
I have an lmm and a bought a s480 kit and I wanna go with 100% over injectors and 12mm cp3 and I wanna make around 1000 hp what turbo do you guys recommend
67G2 and s488 will get you there or damn close.
I have a lml 250k miles on it will be doing heads here soon truck is deleted it pushes 35psi don't know how I bought it like that. Looking to get a set of heads from choate with ring work done I will change bearings as well and compound it .
I pull a 20k trailer once a week on the mountains 7 to 8 degrees slope will the 475 trow a rod? What would yours guy's recommend. Believe or not my old LB7 with 350k did a much better job PPE max out sometimes I use the old bully dog with crazy larry 😜 couldn't kill the the truck until I rolled of the mountain....
Just looking for lower EGTS I will ARP stud it too.
THANKS
We can help with turbo sizing, give us a call 815-568-7920. Tuning we will not be able to help with as it is deleted though.
What size turbos would you recommend to efficiently make 1000 rwhp at 5000ft elevation on a 5.9? Currently have a single 472 and want to put a 488 on top but I’m wondering if I can downsize the secondary a bit to reduce the LAG
How do you plan on using the truck? Will you be doing a lot of towing? Do you want to drag race?
@@Duramaxtunermostly a street hot rod and some drag racing! Towing could be very little..
@@ronnyenns9469 What year 5.9L is it? Assuming you have a common rail, a 3rd Gen Stealth 67G2 and s488 has proven to be a nasty street rod setup.
Kind of a silly question but is there anyway to retain your engine brake with a compound kit? (18 2500 Cummins)
I'm don't know for sure, but the newer cummins engines exhaust brake by closing the vanes on the vgt, if you compounded with the stock vgt and an s400 the factory exhaust brake would work I would think. Although you probably already figured that out.
If I had a nickel for every time I heard a diesel bro call a compound turbo set-up "twin turbos" I'd have enough money to pay for the never ending truck repair bills of everyone who thinks they need 1,000hp daily driver...
Love being called a "diesel bro"! Thanks, it makes me feel young enough to change my mind on how I phrase things.
I have am LMM and a SXE488 from another build that didn't happen. I was going to do a 475 but i have this - Is this too big? Planning built motor, 60 over injectors, fass, 10mm cp3
We see plenty of s475 over twin kits. It always comes down to what your ultimate goal is of the truck.
95 12valve. 5x.014’s. 191 DV’s. Hotrod mechanical pump. Studs. Valve springs. Afc mods. 22* timing. With a 64/68/12 s300 currently. Looking to add the best sized s400 into the mix for an all around driving mix.
Hey, give us a call. 815-568-7920
2 questions...
1. Can you run compounds on a LBZ Duramax without deleting the EGR?
2. 2006 LBZ Duramax used as a backup daily driver, mainly for towing and occasionally at the dirt or street drags. I have already done the Stealth 64 turbo with supporting upgrades and stock injectors. Lets say I'm looking for more power but still use the the truck same as stated above. If going to a compound setup, what do you recommend for a primary (atmosphere) turbo? Do I need to replace the Stealth 64 in the valley with a stock turbo?
Have your stealth 64 on my 06 Cummins. Would an s480 pair well with it?
martin1234512345 Very potent combo. The large turbine on the stealth 64 is a good match for the 480 and even the 488sxe
Nick Priegnitz awesome! Thanks for replying
So does this information carry over to a powerstroke application? I've been wanting to do a compound setup for light towing and alot of fun and I'm really confused
Most of the advice given this video should translate well to the Powerstroke market. I’ll be honest and tell you that I haven’t done any Powerstroke compound turbo sizing. However, based on the engine size and factory turbo charger selections I see no reason why the theory should not apply there.
@@Duramaxtuner thank you, I didn't think you guys would have much out there as for powerstroke specifically but the information you guys do have is amazing and I love watching the videos regardless.
I recently purchased a 2012 duramax with a wc compound turbo kit it don’t perform like I think it should what are some things I should look for to Diagnose the problem
Boost test it from the face of the atmospheric charger. Also, most guys neglect their air filters on compound trucks for some reason. Fresh air filter and clean the MAF while your at it.
I have a 97 Cummins with a 4" tail pipe. Stock injectors looking for better towing and cooler running. Have larger all aluminum radiator. My 46re has steel 6 gear sun gear, upgraded torque converter and bilet drive shaft. With a shift kit and gm solenoid. Any advice. Would like cooler towing and to not lose any fuel economy while getting better towing.
s400/stock compound kit is hard to beat.
@@Duramaxtuner i getting ready to order a torque converter 47re and looking forward to doing a sequential twin turbos IE compound turbos. And going to the 400s (S475) so what torque am I looking at and were would 5he ideal stall be to kick in on time? 97 2500 4x4 4re stock injectors.

This might be a bit left field but I’m currently building a compound turbo KTA19 Cummins and need some help with turbo sizing. I’m chasing about 1200hp at the flywheel with a max rpm of about 2400rpm. Most of the time it will be operating between 1200-1900rpm. Any suggestions??
Sounds like an awesome project. We would have to do a bit more research to see what they have to start with.
They run a Holset HX80 standard I believe
So matching turbos, on a cummins 6
7, how well will a 364.5/80/1.0 and a s480/96/1
32 be? My goal eventually is 900+ to the wheels
That is a pretty common setup. Should be good fun on the street.
What size injector and cp3 should I run in that setup
Wath do you think on a s484 over stock lmm max effort tunes
francisco munoz we’ve seen trucks Dyno mid 900’s with that combo, a couple even tickling 1000rwhp.
06 5.9 Cummins....tows 10k maybe 4 times a year....shooting for the best setup for 800HP. Weekend fun truck 95% of the time. 100% Over Exergys Stocker/S475? Stealth 64 / S480? Opinions? Thanks!
All depends on what you want to spend. I went semi cheap on the turbos: My setup on my early 04 is a he351 (opended up wastegate and billet wheel) over a s475 using crazy Carl's kit. 60% nozzles and dual fuellers. I tow with it all the time and it spools similar to stock. Smarty on lvl 4 with no added timing, torque, or rail pressure. Egt's can get in the 1300-1400 range on long pulls with a 25k lb combined weight in 6th gear but doesn't have any issues keeping up speed.
Previous truck was a 01 24v and had 100% injectors and bd race twins. I couldn't tow with it at all. Laggy and high egts. I only had an edge tuner back then, so there are probably better options now. I like the smaller primary turbo and injector setup better for towing.
A stocker/s475 kit is going to give you the most bang for your buck. the Stealth 64/s480 kit will make more peak power but it's hard to beat the $/HP ratio of using your stock turbo (assuming it is in good condition now).
Whats a good company that can do an add turbo kits 750-775 for 06 cummins?
Hit up WCFab for twins, our Stealth 67 works perfect up to 800+HP.
Want to do this to a big block grudge car. These things have big advantages. The turbos hardly work. I know the importfaqs are big into this . Making 3k on a 4 cyl
Should talk about your gas tuning too! I always get positive feedback from the gas guys running it
Thanks for the plug Kevin! Look for vids soon, we've been very busy adding Ecoboost support. :)
Is there 3.0 duramax tunes coming too ?
Can't say we've looked at it yet.
Wondering if 3" exhaust is too small form a s464 secondary to a T6 s475?
Most would run a 4" or 5" exhaust with that setup.
@@Duramaxtuner okay so it should be a 4" from the S464 turbine housing to the inlet of the S475 turbine housing?
I have a 2001 Dodge 3500 and I pull a 30' toyhauler. 5.9 Cummins with NV5600 6 speed manual Transmission and 3.73 differential gears. I noticed you didn't say anything at all about EGT other than to say certain things make a lot of heat. I'm not really interested in super high horsepower. What I want is to be able to use all of the power my truck has without the EGT going sky high. I also want quick spool up and that means compounds. My engine is factory rated at 245 HP and 505 lb/ft of torque. If I could just use that all on a long steep grade that would be great. I don't like high RPM. The truck I used to drive redlined at 2100 RPM and I know I'll be turning more than that with this smaller engine but I don't really want to turn more than about 2500 RPM. I'd like to keep it between 1700 and 2250 if I can and EGT no more than 1200 maximum. I've had to downshift on a couple of grades to 4th gear to maintain any decent EGT. Given my distaste for high RPM on this engine, that means I'm only passing the most heavily loaded truckers at 45 mph in a 65 or 75 mph zone. So I don't want to increase fueling, it has plenty of that I just want a better air flow. What size turbo should I put on to feed air to my Holset HX35?
Witch kit can i put on a stock lly and be able to tow whit it and how much hp can i go whit the stock fuel system
A Stealth 64 VVT is probably the right match for you. If you really want twins, an s475/stock is most likely the ultimate kit for towing.
@@Duramaxtuner the stock turbo on a lly is it the same as your stealth 64 vvt
Now what's biggest difference going from a 1.15 ar to a 1.32 ar housing on atmospheric charger?
It's going to impact how quickly it can spool up and how much peak power it's capable of. Tighter AR will give you quicker spool up (lower RPM efficiency) but sacrifice some peak power.
I recently talked myself out of compounds after Jim talked me into it. Before I pushed play on this video I hesitated. If I watched it I figured I would want compounds again. Dang it... That's exactly what happened. I love your videos, but they cost me a lot money.
I'll tell Jim to follow up with you ;)
I already have a Stealth 64. Not looking for more power. It's a duraburb so I'm not trying to race anybody. Just need this beast to pull my 10k pound trailer up the Rockies. So, s475 with which turbine housing? Is the 1.15 really worth it?
Hi Nick, please help me out. I'm doing a compound setup on my vehicle but I can't find any info on anyone that has done a compound setup on my specific vehicle.
It's a Ford Ranger 3.2liter 5 cylinder TD.
Currently I'm making 350hp (stock 197hp) & 750Nm (stock 470Nm) at flywheel. I want to be able to make around 450hp and 1000+ Nm.
I have no clue how to size the bigger turbo as I want to use the stock turbo that has slightly been modified(hybrid).
My current turbo has a lot of turbo lag and won't be suitable for the setup.
Where do I start and can anyone help please?
I have another borgwarner K27 turbo, maybe that will work with the stock Garrett powermax turbo...?
Thanks in advance!
@Nortifyer Your modified stock turbo should work well as a secondary turbo for a compound setup. The BorgWarner K27 would also work and probably get you the 450hp you are looking for out of it too. It's all about finding a turbo that comes into its efficacy range right as your secondary turbo is falling out of its efficacy range. If you might be looking to make more than 450hp later down the line something like a BorgWarner S252 or S257 would also be a good match for the power you're going for combined with the efficacy range of your stock turbo. Check out our video on sizing your compound turbo system for more information on the topic: th-cam.com/video/oSdusJZG9AU/w-d-xo.html
@Duramaxtuner thanks for the comment!! Appreciate it! Love your content!
For someone who is responsible, I swear I am, for an s475/stock how quickly will I need to upgrade the transmission on my LMM? No flooring it = no problems???
Lots of guys run our Stealth 64 on a stock transmission truck. It has more to do with your tune and driving style. The turbo wont just make your transmission fail. Abusive driving will.
what would happen if i would use a wastegate turbo for the small turbo and put a massive wastegate on it and use a VNT turbo for the big one?
I don't it's been tried before.....
Would love a stealth line for my 2.8 LWN duramax!
👍
Have a stock replacment batmo compressor wheel and 10 blade turbine on the OEM turbo, will this be an issue compounding?
Shouldn't be. The batmo generally performs just like stock.
@@Duramaxtuner except at 10k+ feet, it's been great even through the grumblings of the guys at my shop saying I should have put a 11 blade on it. Thanks!
Do u have to build the engine for that
IF you're passing 750HP+ You're going to want to build your motor.
Is compounds worth it for towing
Yes!
@@Duramaxtuner i have a 2007.5 6.7 that has been deleted. The truck has a 2 piece 5.9 manifold with a 64mm phatshaft installed in the stock location. what can you do for me?
Dammit and I just pulled the trigger on a 67G2 for my LML ultimate goal is to go twins now I’m second guessing my buy
Nightmare SS Don’t panic. We’ve tuned plenty of 67G2/488s to know you’ll love it when the time and funds allow.
Nick Priegnitz I know who I’ll be calling or going to when the time is right then! Thank you for the awesome videos keep it up bud.
Duramax 3.0 Please
Easy drinking game here, this guy has the record for saying turbocharger
Poor lly its just bad all around huh. Do you need a built trans before you put a compound kit on?
We would suggest a built trans before doing compound turbos.
@@Duramaxtuner thank you
How would a cheetah 63.5 in the valley with an S476 do ?
Would work. We say Stealth 64 though😉
He is using twin, sequential, and compound turbo charging interchangeably I'm confused.
Y’all are obviously huge on tuning....would you say this all still applies with mechanical fuel injection? Aka us p7100 guys
364.5/73/14 & 480/96/1.32
12MM P7100 24v
I'm gonna run Headstuds without O-ring and dog it and see how long it lasts, 4k GSK so i'll probably do Rod bolts and of course pushrods and valve springs and send it
@adudenamedjeff3962 You should be fine with just some head studs and a new head gasket. Sounds like she'll be pretty rowdy though.
What is the story about the Ford in the background?
Good spot! More to come on that soon.
Duramaxtuner what’s it take to get y’all to put a compound kit on my 2019 Limited f250?!
Where is the l5p twin kit
Come drop off your L5P and we will build you a custom kit.
@@Duramaxtuner it's coming in April for the tranny and tune I already spoke to Chris emkhei about 3 weeks ago it's the only time I'm off so unless you can build a twin kit in 3-4 days that is a big no
