That motor should have made 1000hp on 14-16lbs with that 88mm somethings wrong!
@@bigboreracing356 They dropped their goal, first 2 episodes they repeatedly said 1000 horsepower with the turbo.
It was only in a 9 pound spring. Was probably making 10-11 psi with controller
Agreed 100%
don’t matter it made 573hp on motor bro… 14.7psi will always double the n/a power.. with the proper size turbo and that’s a Pt88mm so it is proper..he said he put a 9lb spring in it. And turned the dial 5-6 times, let’s just say it was on 9lbs and nothing more so spring pressure before turning the dial that’s a 61% gain in atmosphere.. and 61% of 573hp is 349hp gain.. 573+349=922hp and that’s only on 9lbs. 15lbs that thing would be making 1100+ and he clearly said in the video it should be making 20lbs before he even turned the dial 3more times. And if you take a look in the video looks like they are stopping the pull early maybe it’s getting valve float and not making power after 5500 or maybe the cam specs suck. Maybe it’s the 3step colder plug they used. Never seen anyone go 3steps colder on a mild boost setup. I use br7ef on e85 & make almost the same power as him to the TIRE on 16psi, with a 82mm on a 366ci 6.0L
@@SmxsucksI’m even going to read the story you wrote, but stock bottom end 4.8’s can make this much power.
A well built 408 turbo with the right size and boost should be making 1500 hp and not even break a sweat.
My goodness LoL I've made that kind of power with gen 4 sbe 4.8's and 5.3's with basically a badass hydrologic roller cam and pac and btr valve springs with stock 799's and even some very mildly ported 706's on methanol and with a cats wheel Borg s485 and a billet wheel badass s488 from forced inductions I know the 5.3 was making over 1000whp just based on weight and E.t my fastest pass with a 4.8 with the 85mm 1.15 t6 housing was a 5.57 @ 3200 pound and 5.44 with the big 88mm both had the same th400 butt different ptc converters specced by dusty bradford Holley EFI VP m1 a cheap 102 mm summit brand intake and throttle body and billet Atomizer 325 pounders I got a decent deal but didn't car forem all that much they would stuck open alot more than I cared for LoL I was turning the shit out of both shifting at 7300 and goin across the stripe at 7800-7900Rpm. If I built a 408 with those heads and a good rods and Pistons and it didn't make 1200 plus after The tune was halfway right I would be pissed lol it would definitely be on E90 or e85
865hp? Nice, i do that with my junkyard 5.3 😂
How’s that 5.3 holdin up
Just fine
Dude, this was a give away engine. They're not trying to push it to it's limit for someone to destroy it and get a bad rep. It's over built on a safe tune. Just like every engine in every car, it's built for longevity. A BMW S58 3.0L inline 6 is rated at 525HP. New bigger turbos, injectors, tune, etc., they're making 1000HP on stock internals. So imagine factory internals that handled 1000HP only running 525HP. Overbuilt for longevity.
It’s so cute to watch their reactions. Can we see the dyno screen? It’s kinda old to just watch them clap their hands when the dyno ends. Show the data!
Take a camera and go film your computer screen, tell me how well it looks
They show charts in post edit.
@@adamboyle3331 I’m fairly sure a licensed professional production company isn’t filming any screens and has capabilities to accomplish showing us that data by casting it. Not that hard.
Usually they do show the screen... when they don't, you know it was a crap run. Remember, products they show are also sponsors... so they did the best they could... even the company rep split before the final run. The engine also has a serious pause/hicup during acceleration on all the pulls they showed. That set up will eventually destroy a perfectly good 600hp LS, which I believe is a capital crime in some states.
@@adamboyle3331 Then how come they were so easily able to do at 7:44, hmmm???
That basically was my comment as well. I'd like to see more data. A/f ratios etc.
Sounds beautiful.
Man I miss Mike Galley.....
Where is him?
That’s some pretty disappointing numbers for a motor that made 573 NA. Should make 1146 at 14.7psi in theory.
Yessir it should have doubled its n/a power with double the atmosphere. With it being racegas and a 88mm. Something is definitely wrong.
@@Smxsucks by the sound of the pulls, they didn’t rev it high enough and I’d bet they were way too conservative on timing. My old 6.2 made 1210 on an engine dyno at 15lbs but that was on E85. Something is either hurt or tuning was terrible
Yep, came to the comments to say that.
@@bigboreracing356 it’s not about achieving or not achieving their goal, it’s about it taking over 20psi to add 350hp when it should have taken 10psi or so.
@@bigboreracing356 I understand that. The issue is that it should have made 1146hp on 14.7psi not 900 on 23psi if it made 573hp NA.
I heard the reasoning for the 1 5/8" tube headers, but those seem tiny on a 408. Wish I could see what back pressure numbers were on that hot side. Should have 1 7/8" tube or even bigger cast turbo log for exhaust.
The bp is gonna be limited (or should I say raised) by the hot more than anything in a good combo. Exhaust to the turbo is nots important..even the stock manifolds can do 1k+
I don't listen , I don't care to learn from anybody else I have learned alot watching these guys I actually sordve know what I'm talking about now !
Im sorry but this is the the first time ive seen (sort of) being spelled like that and im from Oklahoma and "sordve" is exactly how it is pronounced here lol. Not being an asss just thought it was funny because thats exactly how we say it TBH.
actually no, these guys are shade tree mechanics. it takes years to learn this stuff and your not going to learn it from RUclips videos.
No power is used, however power can’t be lost do to restriction and back pressure so using larger hotside can have huge gains on the higher rpm range but cause lack of spool and boost lag. Turbos like any power adder have +\-. Wheel to housing ratio and flow rate to psi can be a HUGE factor in true power. Love y’all keep up the good work. 2000hp or die
That's an insanely expensive 865HP.
That turbo on log manifolds, on a stock 6.0 would do that easy and way cheaper.
@@bigboreracing356 shouldn't take 30 psi to make that
True but how long would it last? This thing would last forever at such a conservative Tune.
Ideal 6.0 build out? Looking at 6.0s right now.
@@whatta7793 there’s no “ideal” build out. Just depends on goals and application
@@Mastermindyoung14 lmao BBR deleted ALL their comments on this entire video 😂
I love this channel
I'm doing the Red Tide 5.3 swap on my 91 k1500. This engine would definitely take my build to the next level.
I'm digging the VHT. I think im gonna go get some for my new project cars headers.
573HP N/A is good.865 HP on the same engine with 20psi is weak sauce. Something was definitely wrong-they didn't even show the whole dyno sheet. There is some sort of control issue I think.
Exactly! something wasn’t right there, I was really disappointed with those boosted numbers, 20psi should’ve been around 1500. I thought with the 1400 block rating we would’ve seen 1000 at least. And what happened to the other guy? It’s like they just gave up, surely they wasn’t satisfied with those numbers, or maybe they did find something wrong and just hid it. If Holdener was performing these test I bet we would have seen some good numbers or if we didn’t at least we would know why. I’m trying to copy this build so it really was disappointing they let it go at that.
@@bigboreracing356 corrected numbers just allows you to “somewhat” compare to other dynos, correcting to specific atmospheric conditions, which doesn’t mean those numbers aren’t correct or close, it could go either way.
That “20psi of boost” must be the 14.7 lbs of atmospheric and roughly 5psi on top of that. That’s the only thing that makes sense
@@stevenbelue5496 Your correct, its a GM product
@Hates Spam it handles 1000 stock lol.
I feel like they kicked the EFI tech out of the shop hahaha
MSD coil packs suck, I've had to replace them constantly. I've had 3 fail within a year with less the 5K milesnon them.
I had a set of street fires and they were garbage too. Msd can't make a coil to save their life
@@bigboreracing356 "All MSD coils are made to our specifications and thoroughly tested. Also, the coils for the Pro Mag 12s and 44s, the HVC line of coils and our multiple spark LS coils are all made in the United States."
We use the factory Hemi one’s past 1K horsepower, we don’t like the MSD ones either.
@@bri-manhunter2654 i have oem LS7 coils on mine now and at 700 wheel its still fine.
The only downside to OEM LS coils is some if not all have an auto-fire protection if you feed them excessive dwell. With the right plug & gap you shouldn't need more til you're putting 4 digits to the wheels.
VHT works great. Aside from a couple of touch ups, I've been running it on my drag truck for 7 years and it still looks good. I run 113 octane and it's never burnt off.
Great show guys. I would love to have that turbocharged engine lol that would be real nice in my 2014 Chevy Silverado
Your 5.4L with ring gap, cam, springs, stock internals, and boost can put up some good numbers too.
Does anyone else think a 408 single turbo should make north of 1000+ horsepower?
At 20# that engine should be pushing over 1100 hp.
That setup N/A is on point👌 boost is fun but the power it made N/A is amazing
Amazing and immediate.
Was it me the engine has a big hiccup when the boost came in
I need that setup
REV that thing guys! All those fancy parts for "extra insurance" only to baby it in order to not hurt the fancy parts lol
They couldn't. They only did a trunion upgrade instead of putting in a set of Harland Sharp rockers.
You guys should see what many, many others are doing with stock 4.8 liters. Imagine what those guys could get out of this engine. Guess you have to start somewhere. 👍
Except this is reliable power and not a few hero passes on a junk yard motor
Plus this was only 10-12 pounds
Tell me more about 4.8s would love to build a reliable true sleeper
@@loweredyote8416 I think they said in the video it was roughly 22 lbs. Sum Ting Wong, this should have made WAY WAY more power at that boost.
@@neilsmith8790 I thought that too but I took it as supposed to make 22 pounds but only made 10-12
Keep the good work up love your videos
Great results guy's, What sort of cam and comp did you have?
My LS isnt in yet and I'm ready for an upgrade
When are you guys going to build a 318cid la and 318 magnum and compare them???? Hopefully use same size cam and after market heads ????
Cool set-up, but im not sure if I care for that hot pipe going into the turbo should be nearly touching the pipe going right into the motor. Seems like it could create a heat issue
Its really not though. The exhaust wrap that is there keeps it to a minimum. I dont like it either but its almost negligible.
Pat is king. Period.
Terrible power for an 88mm turbo on a 408 cube engine. Especially on 22psi. This thing is a a boat anchor. I'd be too embarrassed to make a video making that low power on a combo like that. Sponsors will be pissed. 😂
I was thinking the same thing. Should have made at least a 1000hp at 15 lb of boost. I've seen stock 5.3 with big turbos make more power than that at the wheels lol

The oil fitting they provided would send unfiltered oil into the turbo…
Ill.take na
What happened to the boost control solenoid? You had one sitting with all the parts on the bench, but then used a crappy manual boost controller on the dyno???
Oh hell yea the better episodes with mike galley
You had a electronic boost controller at the beginning of the video. Turn up the duty on the controller 😎👍
3 port Mac valve. 15lb spring = 30psi turning up the duty
4 port watch out it’s going to the moon at a certain point with very minimal duty change. 5lb spring can make 60 on a 4port
That would go good in my pickup all these guys around here think there stock engines are the most powerful around I would like to show them with this engine
2:49 It is not for free, my friend. A turbocharger takes torque/efficiency out of the exhaust stroke lol. If you disagree, ask Gale Banks)))
Not as much power loss as the twin, root, and centrifugal blowers.
@@bri-manhunter2654 Correct . And that`s not what It`s about. What`s driven by belt, takes efficiency out of all 4 strokes in a 4-stroke engine. If a random twin might take 1/5 of engine`s power at high rpm, a random turbocharger might take 1/25... But the guy said "None of the engine`s power`s being used" and that`s a huge mistake.
@@Riptidevulture. It’s Phydics 101, energy is never free.
Great video. I’m no mechanic but how are you going to fit that beast of a motor and turbo setup under the hood of a car?
They're swapped in everything. Miatas, 240's, Supra's, lambo's, etc they're not very big.
@@KE458S he's talking about the crap hanging off the front. there is no way that turbo setup is fitting in a engine compartment. who ever wins that thing is going to have to reengineer the exhaust and turbo.
Different piping setup. On the dyno is just showing us the potential.
My Yukon used to get up and go
I am not sure if I would run non filtered oil to the turbo but that's just me.
That stupid rtv between the turbo and manifold is probably preventing them to boost properly because of leak, must use mls gasket or embossed
Wow wow man I really love this show
How does the addition of the turbo lube-oil takeoff from the main oil gallery affect the rest of the system pressure? And, do you install, or recommend an engine oil cooler/radiator?
Catch can and an oil cooler, 100%.
I usually REALLY like these videos. I've been following this engine build series since part 1 was released on RUclips. I know this video aired on tv a long time ago.
I have to say though that this video was a pretty big disappointment. The way they came into this series at the beginning of this build really made it seem like they were going to show us what this engine could REALLY do. Now, they did show it producing some good horse power at the end, but I was not really "wowed" by the final result. It even seemed to me like there was something a little fishy going on with the motor during the dyno pulls. I'm not an expert by any means, but I just felt as tho the final result came up a little flat. Especially considering all of the talk in the video about 'how much power this whole build is capable of'.
Seems like something going on , it falls on its face before a pull no clean power
Biggest change over the last 10 years is computer control over everything is WAY more granular and has more complete control letting us push engines way closer to the edge without pushing them over not a luxury they had in 2011 900hp back then was big big numbers ....2nd big change is our turbos are so much more efficient now ....just my 2 cents on why we look at the 900hp and go wtf we are jaded and forgot how hard it was to make that 1k mark 10years ago and be safe
Heating them up is like powder coating them so the coating hardens
Thanks for watching.
I wander what else I can use that VHT on 🤔
Which one gives more horsepower turbocharged or supercharged gas engines only 👍
I bet if they didn’t use RTV the numbers would have been better.
now did you make the boosted pull on pump fuel? 91? or 93? or something else?
?
what brand is the injector cleaner
What was the static compression ratio NA?
Needs an electronic boost controller and back pressure sensor something badly wrong this thing should’ve made way more power it made power like numbers on for 5 pounds of boost. It had to of quit making power before 5200 RPMs for the torque to be higher than the horsepower indicating major back pressure issues.
Why the msd coil packs over the stock gm ones?
Galley!!! Dearly missed
Who remembers watching this (or something similar) on TNN? Later, Spike!. PowerBlock(TM)!! XD
Yep
550 HP is a walk in the park for a 6.0. Let alone a 408. It needs more cam timing for the 6.0 let alone the 408.
Those are numbers you’d get with a 6.0 SBE Gen 4 with a cam. That a 88 mm turbo on 20lbs of boost. It’s should be making 1200 HP at that boost level on a 408.
What happened to the turbo nut at 2.18
how are you the only comment.. i came here purely for that hahaha
Could someone please help me finds the spark plug gapping tool he used!!!
Ya idk, on a 600 hp na motor with 15 lbs of boost it should of doubled the hp
I have this coming up thank or you so much for sharing
Terry
I'm surprised they didn't run a boost referenced fuel pressure regulator, that would have automatically added fuel as boost increased 1:1 . Also the ECM should have pulled timing in proportionality too the boost increase. That way they wouldn't have to worry about changing timing manually. I'm running a Terminator X-max and it does all that automatically after initial set-up....Seems they weren't adding fuel and pulling timing as the low HP numbers verify....
i run a ford small block 351 stroked to 408 putting out on a single turbo 123mm 2000hp at the wheel. it works good enough for 5.96 passes on the track in a fox body.
@@bigboreracing356 you really have room to go. wish I could send you a picture, keep up the great work.
Thanks gays
Yeah I like to cry I love your show and I sure like to try to try to win that in for my car what that'll be a good in you for me I love your shows
Those headers were way too small! It honestly should have made that power on 7 to 8 psi! Something was radically off! I honestly hope you weren’t @ 21psi! A crappy 4.8 with a 160$ turbo will make over 800! I honestly think the headers were killing it, way way too small, probably should have been 2 in, @ did anyone verify timing ⏱? Or even check EGTS? High EGTS will tell you if timing is way too low!
Can pre ignition cause an engine to blow the head gasket?
no
What was the static compression on this engine
Stock it was 9.5:1. They did a piston change to bring it up to 10.5:1. That hurt them badly.
105 + 20psi on a 570+na hp engine making less than 1100 don't make sense.... AT all.
Yea something wasnt right there lol
Was thinking the very same thing. Something very wrong.
Must be a conservative tune in it.. should make that at 15psi.
@@KE458S that thing had 21* of timing and 20/21# of boost before they gave it "3 clicks" on the boost controller lol
@@jesselee128able i agree something was wrong with it.
it didn't respond like it should have
That setup shouldve made 1100hp on 14psi.
At 14 psi that motor would have made around 1350hp. At 10 psi it would be around 1100. Thats an 88mm turbo on 1 5/8 tubes. The wrong cam and wrong lifters were installed and they were blowing all their boost out of the exhaust valve.
Mike: Are You sure you're not a relative to Aaron Rodgers (GB-Pack's) in your 5th or 6th gene?
🎉🥰👍🏼
Is it just me or is the Intake pipe resting on the downpipe ?
Now fit all of this set up under the hood of a car..
Wonder if it was having valve float issues. Hellion is known for high back pressure with resulting valve float on their Mustang kits due to poor manifold design.
Nah, this was mostly the wrong cam and wrong rocker set up. They were blowing their boost out the exhaust valve. The coked the crap out of that turbo also because the plug was WAAAAAY to cold.
A 409 would be more fun, fun, fun.
1200 Hp, 1100 torque?
Please pick me....love this show
Season 1... that was awarded to some sucker years ago.
Let’s enter to win something they gave away 7yrs ago. They need to post newer episodes!! 🥱🥱🥱
Something wrong here boys, at 20 psi this thing should’ve made way more power. The first clue was that you needed that boost tee to keep boost. Waste gate is faulty.
That's some Fucken power
Gotta put a better cam
Whats the COMPRESSION??????
something is not right with the setup, I own a dyno shop and make that hp to the tire on 5.3s with less boost. You guys need to start using holley efi systems they are far better.
theyre very conservative with their numbers in case you havent noticed by now
I agree. I'm making 560 whp with a bone stock 5.3 at 14 psi. With the suitcase full of money they threw at this thing, they should have been over 1100 at the crank.
Depends on the cam, compression, and timing used. But, as a dyno shop you should know all that🙃
21degrees of timing and 20Ib’s of boost, that was a hurt motor they were trying to hide.
Listen as they roll into the throttle you can hear it layover. Something definitely seems off or hurt.
@@nooch8it197. Agreed
Would be interesting to see an engine running a turbo without ducting the output back to the engine. To see how much parasitic loss there is with the exhaust restriction.
You only did half the job on the headers, the ceramic coating needs to be on the inside of the tubes as well as the outside.
Don't know what car that would go in like that 🤔
No power come free……ever, that cooling fan is way to close to the inter cooler as well, looks like a nice build but expected a lot more from a setup like this to be honest
I wish I could put this engine in my 98 K1500. really need to update my old/tired 350 small block.
perfect 😍
Did anyone happen to see how shitty that deck surface was. They gave away a ticking time bomb. That mfer gonna blow a head gasket in no time. Deck surface was pitted and scratched to all kinds of hell.
oh wow, another LS and turbo set up 🥱🥱 🥱
6000vortec
That fan in front of the intercooler though!!!! REALLY?
The waste gate should not be a 90 degree to the flow. It’s blowing right by the gate
Although that's optimal, it doesn't matter that much because it's pressurized.
@@nevosrestos394 wrong.
On a twin turbo set up, I would agree. On this setup its about blow off time. The valve is big enough to make it negligible.
More back pressure too. Not great
You need to do a Chrysler 408 stroker now
🤷♂️ Where’s Mike Galley nowdays ? He completely disappeared…
