The fact that I started watching you over 5 years ago on the 5.3 teardown and rebuild videos to randomly seeing your recent videos looking for more info for my turbo 5.3 ranger shocks me. I think you had like 30k subs back then. Way to go man! Keep the info coming. You're awesome!
That's super cool info and alot of hard work and punishment dished out by that built 5.3 of yours to set some benchmarks for your product. Great stuff great data great video.
Awesome finally someone gives a honest test with back pressure only thing could even remotely be better is similar test with LSA comparison on different cams for back pressure test thanks for a real tuner vid great info!
Incredible what the stock 5.3 crank can handle with a quality turbo pushing steady airflow without being peaky or overly sensitive to dome pressure changes.
Great video man! I didn’t realize how much dome pressure is needed to get above 30psi. With my s484 from forced inductions about 25psi i lost the 1:1 on dome pressure to boost pressure so i stopped adding dome pressure. This spring I will have to put 50psi to the dome and see what it will do. Keep up the good work man. My dad and I really appreciate and enjoy your videos.
We found not to rely on dome pressure alone. Do yourself a favor and put in a BP sensor, and then compare them. Keep going until you hit the point of diminishing returns.
Nice video, well done. I like your format. I would like to mention I’m not in love with whatever cam you have in there based on the results. But whatever, if it works for you then that’s all that matters. Keep up the good work guys.
Was waiting for you to break out of the Formal voice character lol not even a "eazy peazy and don't forget to get that V" at the end haha . Loved the video dude!
Maxing out the turbos almost maxed out the engine. After that last run, I'd want to pull the motor apart and see how all the bearings and everything else faired. I wouldn't be surprised if some head work is needed. The turbos did very well overall!
Great testing. Reveals the 96 turbine is not the cork in the system. It was people asking too much mass flow from a undersized compressor leading to extreme exhaust drive pressure. Of course, if we look at borg warner s400 compressor maps we can see the WHY for the results
A very good video. I would have liked to see the torque and horsepower lines cross at 5252 rpm and naturally the compressor maps for the turbos. Tuning on VE, the airflow is calulated and could be plotted onto them. :)
What a work horse. I was definitely expecting more of a difference in power numbers but I guess if the backhousing was similar If not the same then it makes sense
Awesome video, respect for all the work involved! Would really love to see the same test but with various turbine side changes. Would be a lot more work no doubt!
thst back pressure is outragious for sure. nearly 3:1 is nuts. i run 2 s475s with 83,1.0 and literally 1psi difference dome to boost gauge. yea them 103mm are a huge help in the s400 chassis turbos to be more competitive.
It shows on the dyno graph, granted each will be different from dead idle to WOT but on the dyno already up in the rpm it wasnt enough difference to matter on track
Not really since they didn't change turbine sides. Turbine side changes are the #1 cause of spool change, compressor side changes don't hurt spool much but can really affect the top end power limit, as seen here. Turbine changes massively affect spool and power limit. I run an 82x75mm turbine for maximum spool on the street on my 5.3l.
There will be a significant change in response rate from a 76mm to 88mm compressor on the street. For drag racing where you’re on a 2 step you won’t notice but street driving I guarantee you will.
That’s an awesome test. Nice work. Love the hub dyno. It don’t lie. We had one in the shop I worked at and it’s by far the only way to go. I’m in the market for a turbo here soon. I’m gona check you guys out. That 85mm would be perfect on my destroked 6.0. It’s a 4.8 crank with a 6.0 block .040 over. I think that would work just right for the set up. Going for a hi revving lil 334ci but I’m going powerglide. A th400 would be too much of a power robber for that set up. I’ve used many. But a glide is the way to go.
Hey I have a 07 tbss with a 416 lsx, afr 235 heads done by Tony mamo. The static compression ratio is 9.5-1. I have a huron speed t6 turbo kit with a s480 80mm work turbo 96mm exducer wheel 1.32 a.ron it now, I feel the turbo is to small for the ci.. what are your thoughts and if I were to step up to a bigger to how much bigger? An 88mm or bigger given the c.i.? Thanks hope to hear back.
@5:57 the graph on the dyno computer shows around 1050 hp at 5190 rpm, then you cut to a graph that shows you werent making that power until 6500-6600 rpm, whats with that.
I have a question, I’m building a budget lq4 6.0 with springs and sloppy stage 2 I got a cat c6 turbo for free from work it’s a 96mm turbine 1.72 ar housing T6 flange and 87 mm inducer and the 110mm exducer on the compressor, I know is going to be lagging as hell but do you guys think it would even be worth it, it’s a brand new name brand turbo it’s going in a 4000lb 4 door th400 3000 stall 3.73 gears and 31” tires 5:55
I’m building a 415/416 out of a L8T LT block what should I use if I go single turbo and what should I use if I go twin turbo. My goal is to see at least 1400hp. 60% street 40% track
Loved the video, I have a5.30I am doing a first time turbo om and would like to get some help on suggestion on waste gate and BOV size to use. I see you have BSI products WG and I am looking @ them . I have a GT45 E bay Turbo (T-4) was recommended a 60 MM waste Gate and 50 MM BOV does this sound correct? Thank You.
How bad will the back pressure be on a 11:1 408, Dart heads w/a FIS 91/102 T4 flanged turbo? Is there anything i can do..? Jose offered a V band exhaust housing, would that flow better? If so, I'll go ahead and get it. I know I'll be adding a 2nd gate, but other than that, I have no idea what to do or expect! Thanks man! Congrats at TX2K too!! Hopefully my motor and turbo will put me in the low 8's, w/o leaning on it hard!
question bro did u bore over this 5.3 or you just thru piston an rods i have iron block 6.0 bore over to 6.2 416ci with cp pistons and manley i beam rods and eagle crank ls3 top in with th400 from fti and ford 9" with 88mm from btr whts my power looking like?
Like a 7875 is pretty much perfect for burnouts and icecream. To big exhaust side on these for a real fun street car, but the bigger is better for drag racing
350 427 cubes 86 mm is perfect smaller motors love twin 62s noticed once you get into the 500 cubes need a 96 with a 103 dual or a big 112 with a 120 back housing how snot rockets makes 3000 whp on to 76s is amazing
I think you should of stated the back pressure numbers with each turbo as that is the true culprit of HP when sizing a turbo for LS. When you say max effort i feel like ur maxed out with backpressure and cant make more power as the engine is fighting it self.
Ain’t nothing better than straight up back to back results on the Dyno.
Excellent test
That's an awesome test! Great results! That 5.3 banging out some horsepower.
Turbo John!!!!!!!! What’s up man. You’ve been killing it. Keep up the amazing work. Love the new car
The fact that I started watching you over 5 years ago on the 5.3 teardown and rebuild videos to randomly seeing your recent videos looking for more info for my turbo 5.3 ranger shocks me. I think you had like 30k subs back then. Way to go man! Keep the info coming. You're awesome!
Awesome video man. This helps big time in deciding what size to use. Love the channel keep it up 🇨🇦
Oh frig yea I've been waiting for this videoooo. This is sooo much good knowledge and real life data! BSI/TNT the world!!!!
I'd like to see the response difference between the turbos. To see how much a bigger compressor actually effects spool
And on next episode.. we combine ALL the turbos.
On a honda
Issa airplane.
😂😂
That's super cool info and alot of hard work and punishment dished out by that built 5.3 of yours to set some benchmarks for your product. Great stuff great data great video.
Awesome finally someone gives a honest test with back pressure only thing could even remotely be better is similar test with LSA comparison on different cams for back pressure test thanks for a real tuner vid great info!
Incredible what the stock 5.3 crank can handle with a quality turbo pushing steady airflow without being peaky or overly sensitive to dome pressure changes.
I was definately getting a little scared after that 🤣
@@Boostedlifestyle you did say in the video that you were seeing increased coolant pressure...
Solid testing.. that ol 5.3 took a good packing that day lol. Impressive
Great back to back review of the TNT line-up. Very scientific approach and killer results, Kyle. #teamraceteam
I love this sort of content keep it up big fan down here in Australia
That's some serious numbers, dude. Proven top quality products!
It is a testament to your engine building… most garage built motors would have blown up before you mounted the 2nd turbo
Great video man! I didn’t realize how much dome pressure is needed to get above 30psi. With my s484 from forced inductions about 25psi i lost the 1:1 on dome pressure to boost pressure so i stopped adding dome pressure.

We found not to rely on dome pressure alone. Do yourself a favor and put in a BP sensor, and then compare them. Keep going until you hit the point of diminishing returns.
@@Sceviourzx3 good point I will definitely do that this winter.
Yeah like Nick said done pressure can vary depending on how big the top side of your piston is vs how big the valve is
@Boostedlifestyle what size merge pipe would you need to support a ls 5.3 with that TNT 88MM what size ar housing.?
Nice video, well done. I like your format. I would like to mention I’m not in love with whatever cam you have in there based on the results. But whatever, if it works for you then that’s all that matters. Keep up the good work guys.
Great comparison Kyle, keep up the great work!
Kyle you rock! Love the channel and content! Peace easy and get that v!
how this video doesnt have more views, it shows a direct back to back to back comparison of turbo sizes and their effects.
Very informative video that I didn’t know I needed to watch🎉
Was waiting for you to break out of the Formal voice character lol not even a "eazy peazy and don't forget to get that V" at the end haha . Loved the video dude!
I think it would be cool to your 88mm turbo vs other brands that are in the same price range
That is also not out of the cards 👀
Maxing out the turbos almost maxed out the engine. After that last run, I'd want to pull the motor apart and see how all the bearings and everything else faired. I wouldn't be surprised if some head work is needed. The turbos did very well overall!
Honestly I just have to either retorque the heads. Or put new headgaskets in it. Other than that ii think we golden
So is Retorquing the heads on an LS daily driver with 12 lbs of boost something you should do?
Very cool!!! And a deadly format for the video awesome work pumpkin nuts
Great testing. Reveals the 96 turbine is not the cork in the system. It was people asking too much mass flow from a undersized compressor leading to extreme exhaust drive pressure. Of course, if we look at borg warner s400 compressor maps we can see the WHY for the results
Fantastic info, thanks TNT boys!
Great video ! Buttttt there's more to it then just peak numbers. Would love to see the graphs overlayed on top of each other.
Best comparison I’ve seen also wheel speed and back pressure would be nice. thanks
How much of a difference would it make if you used a 6L instead of the 5.3??
Would you recommend a larger turbine?
Depends on a street car sub 1000hp I would use the 96. On a race car over 1000hp I would switch to the 103
A very good video.
I would have liked to see the torque and horsepower lines cross at 5252 rpm and naturally the compressor maps for the turbos.
Tuning on VE, the airflow is calulated and could be plotted onto them. :)
Its a hub dyno, that's why it doesn't cross there.
Tremendous contribution to the racing community! Wow.
What a work horse. I was definitely expecting more of a difference in power numbers but I guess if the backhousing was similar If not the same then it makes sense
Exact same turbine wheel and housing for all four.
@@Sceviourzx3 I thought I heard that correctly
There’s no way this hasn’t been hugely successful in getting True North Turbos more orders. Count me in!
It definitely helps 😁😁 come join the team
Awesome video, respect for all the work involved! Would really love to see the same test but with various turbine side changes. Would be a lot more work no doubt!
It's not out of the cards though!
@@Boostedlifestyle When it goes BOOM, who pays for the new engine build?
Awesome concise testing!!! Great video!
Would be interesting to see backpressure levels at each psi and compare them to every turbo size
best ive seen on youtube hands down
thst back pressure is outragious for sure. nearly 3:1 is nuts.
i run 2 s475s with 83,1.0 and literally 1psi difference dome to boost gauge.
yea them 103mm are a huge help in the s400 chassis turbos to be more competitive.
The best turbo for any engine is a True North Turbo!!!
What about the response rate of each turbo. Obviously the smaller ones will spool/max out faster
It shows on the dyno graph, granted each will be different from dead idle to WOT but on the dyno already up in the rpm it wasnt enough difference to matter on track
Not really since they didn't change turbine sides. Turbine side changes are the #1 cause of spool change, compressor side changes don't hurt spool much but can really affect the top end power limit, as seen here.

Can you list the back pressure VS boost pressure on the tests?
I have the data some where. I believe on the max effort runs we were right around 1.6-1.8 : 1 on most of the turns
Love seeing real world testing
would be interesting to see a s491 or s494 in this test and then just a gt5594 to compare. ill send you mine if you wanna try it.
That’s an awesome test. Nice work. Love the hub dyno. It don’t lie. We had one in the shop I worked at and it’s by far the only way to go. I’m in the market for a turbo here soon.

Amazing work and great results
I Love your content keep up the good work.

An 88mm or bigger given the c.i.? Thanks hope to hear back.
Great video!! Amazing comparison data
Wonder how much it would spool faster with a 1.15 AR and compare back pressure to the 1.32AR on the biggest turbo.
Best turbo commercial ever.
How do you have different back pressures if all the turbos have the same turbine?
Love this comparison !!!!
Did you have problems spooling the bigger turbos at the track and if you did what did you do to overcome it
@5:57 the graph on the dyno computer shows around 1050 hp at 5190 rpm, then you cut to a graph that shows you werent making that power until 6500-6600 rpm, whats with that.

I no this nothing to do with it but how is the F1 car going on it looks class
Alberta boy. I just got a T6 turbo blanket from BSI
I’m building a 415/416 out of a L8T LT block what should I use if I go single turbo and what should I use if I go twin turbo. My goal is to see at least 1400hp. 60% street 40% track
So what would you use if you were running twins. I bought 66s with a 80 73 turbine with a. 91 ar and I'm thinking they might be lazy on the street
Hi would like to know about my last 7.0 turbo. Lsx have a 88 mm Garrett turbo.
20 lb of boost = 800 hp - looks great and would run all day - regular use many years of duty !
Awesome video, a lot of great info 🤙
whats that engine build?
Were these turbine wheels the 10 blade or 9 blade?
Kyle ..I have the same car if yours is a 95 gt original green i have a.99 Sierra 5.3 waiting to go in!

question bro did u bore over this 5.3 or you just thru piston an rods
i have iron block 6.0 bore over to 6.2 416ci with cp pistons and manley i beam rods and eagle crank ls3 top in with th400 from fti and ford 9" with 88mm from btr whts my power looking like?
Wonder what the perfect size turbo would be for a mini f1 car .. lol
What is the AR on the hotside of the 85 and 88?
Shame the shipping price is insane to Australia 😔 $250 shipping for the case of sams detailing stuff 🤣. $25 shipping just for a sticker ☹️
Great video
What size of twin turbo do I need for the coyote 5.0 for 1000 hp
What's the best turbo for an LS for someone who does a lot of neighborhood driving? Smooth, quick boost.
Depends on what youre really trying to do to be honest. We usually base turbo sizes on horsepower goals and future horsepower goals
Like a 7875 is pretty much perfect for burnouts and icecream. To big exhaust side on these for a real fun street car, but the bigger is better for drag racing
@Boosted Lifestyle Goal is to have an epic daily 😂 Drag times would be irrelevant. Definitely not for racing, either.
Building a 408 LS stroker, what do you recommend for it? I wanted to run twins but not sure.
350 427 cubes 86 mm is perfect smaller motors love twin 62s noticed once you get into the 500 cubes need a 96 with a 103 dual or a big 112 with a 120 back housing how snot rockets makes 3000 whp on to 76s is amazing
2.0 is on 83/85s
Awesome video love the info. My question is how much torque will it make when you compound the 76mm with the 85mm ? :)
My question to that is why would you ? Lol
I think you should of stated the back pressure numbers with each turbo as that is the true culprit of HP when sizing a turbo for LS. When you say max effort i feel like ur maxed out with backpressure and cant make more power as the engine is fighting it self.
I thought it was moose power in Canada not horse.
Why don’t the lines cross at 5252 rpm? I’ve not ever seen dyno results that didn’t cross at this point.
It is on a hub dyno going through an automatic transmission.
That compressor is monster sized.
Great vid , thx. What diameter turbine wheels are the smaller turbos running ?
Thoughts on using a G42-1450 on a street 5.3 Miata swap? Good data here, thanks for presenting.
Stop saying, "thoughts".
How much timing at 20 pounds of boost?
How reliable is it?
I wondered if you were going to break it.
Not quite just floated the heads a little. It drove back into the trailer
Why a 5.3 and not a 6.0 though?
Cool vid bro!
what brand turbo
The static compression ratio must be 9:1 or lower. That's a lot of boost for 900hp.
Keep in mind there are a lot of parasitic losses as well as drivetrain losses through the TH400 and rear end. Engine dyno numbers would be much higher
What camshaft? Do you have the part number?
What’s the specs on that ls?
Dyno sheets don't show crossover at 5252. ....what gives?
Sneak peak in the back?🤭
Love a good hp comparo
What rods and pistons did you use?
Shame that Mustang isn't it's original color, that was one of my fave colors for that stang.
Who make or sale these turbos
