- FULL DYNO RESULTS-4.8L GETS CAM, NOS AND BOOST. CHECK OUT THIS VIDEO WHERE I GRABBED A JUNKYARD 4.8L, THEN APPLIED A VARIETY OF MODIFICATIONS. WE STARTED WITH A CARBURETED INDUCTION SYSTEM, THEN ADDED A HEALTHY COMP CAM AND SPRINGS. I THEN ADDED A SIMPLE NOS SNIPER PLATE NITROUS SYSTEM WITH STREET JETTING. AFTER THE NITROUS, I ADDED A TORQSTORM SUPERCHARGER. THE TESTING WAS FINISHED OFF WITH E-85!

Richard, you'll have one-million subscribers very soon, with the excellent, informative content. Every gearhead loves dyno testing!
Thanks 👍
Richard, you need to build a 24 Hours of Lemons car with one of your junkyard 4.8 boosted motors. I'm pretty sure you could get most of the 102K of us to sponsor the build. If everyone here sponsored one part of the build, you'd have it funded in no time and we'd be able to see one of your junkyard creations in action. If you do this, you need to name the patrons "Holdener's Heroes" or something suitably corny! :)
I've run in that race-it's fun stuff
@@richardholdener1727 Hello I'm in the middle of putting a 6.0 in a BMW 328ci could you please let me know a camshaft you think would be good. I've watched so many videos I'm just at a loss.
@@timribarich7473 I had a turbo lq4 with a ss2 (elgin e1840p) and vsracing billet 7875 in my 2001 e46 wagon (325i) Worked great, sounded good at idle, boosted fast.
@@wyfiswanson I have a 200 shot that I am going to use do you think it would still work out okay??
Richard!!!!!!!!!!! How can you leave us hanging like this? The title says "Nitrous aaaaaand BOOST". We only got nitrous then boost. 😢 You know what would be cool. Nitrous hit tapering off as the boost increases?
Love seeing 4.8 stuff, im one of the black sheep with one in my truck
got one in my truck 96,666miles today. Never touched it besides oil changes.
I'VE GOT THE PERFECT SHIRT IDEA! "so, i went to the junkyard..."
So, we got a call...
So anyway I started boostin'...
Why would anybody give this a thumbs down? It’s good useful well explained info, jeez
Would like to see you do an ECU review showing timing, fuel and boost accuracy, setup and tuning on various combos
they all provide the AF and timing-its other things that make them work for specific applications
@@richardholdener1727 I have seen some of the cheaper ECU's bounce the timing around in the higher RPM's, if that is just a physically poor trigger setup or the ECU's themselves having issues would be nice to know. For the AF side of things I hear the fuel film calculation on the M1 series motecs is supposed to be the bee's knees it would be nice to see if there is anything between ECU's on that side as well, even if it was just a general comparison of ECU's on something fairly crazy on the dyno would be interesting. Also some Toyota/Lexus 1UZ content while your at it :)
The valuable raw data and time You have saved guys is insane!! Wish you would add some other junkyard motors for shits and giggles..nissan v6s for example or a subaru boxer engine h6 or ej25 sohc and or dohc. Just would be fun to see some more different BIG BANGS!! LOVE ALL THE ENGINES OUT THERE! HELL DO A HYUNDAI IF YOU WANNA...ID LOVE TO SEE IT!! LOVE AND RESPECT RICHARD!
hard to hook those to the dyno
Good to see some different content on your page, just when i thought i had seen an LS done every way it could be done you pull out a TS blow thru i wanted to see the nitrous triggered with the TS on a few pulls we know the 4.8 can take it
20👍's up Richard thanks again for taking us all to school with you
Haha the guy that yanks out the efi to throw in a nice carb 👌
Big power numbers on the dyno = Carb.
@@Torquemonster440 drivability under any conditions = efi
I appreciate how you don’t hate on things. That’s nice. I am primarily a turbo sb efi guy. But I appreciate a nice carby setup or blower deal. But the idea of keeping an open mind and honing discernment. For example, if you want to learn about wiring, maybe check how they do it on airplanes and boats. Maybe you can learn something and apply it to your hot rod. Same type of thinking and open mind for carb and efi turbo blower nitrous etc. it’s how we get better. Trying to grab the best ideas or methods from each for our goals and doing them. Maybe some ideas don’t work like we thought and some work better than we could have imagined. But the common denominator is open mind and learning while honing the discernment. For example I am a crimper not a solder guy. But that doesn’t mean there isn’t a place for it. Anyways. God bless and keep up the great work.
Amazing how much power and how consistent the l.s motors are right out of the junkyard with two hundred thou on em a lot of times back in the day we could only dream of finding a junkyard motor with even 225 horsepower nevermind over 300 and that responds so we'll to upgrades and lives to fight another day gm really hit it and made it so nice for us hot rodders putting them in everything as well I gotta find an s10 to stick a 4.8 or 5.3 in and have a blast even in stock form it will be scary as hell lmao all the kids around think the old man's crazy any way doing burnouts for em wait till the s10 is done lmao
I love you man!!! You are awesome 👍👍. Videos are great
Glad you like them!
Aggressive cam is the booster. !!! Thanks 😊 Richard
I’d like to see this 4.8 with a lot more nitrous...
I love your videos and tech knowledge but agree totally with previous posts I want to see what happens with boost and nos. The cooling effect of nos may make more power than what the jetting calls for. PS great video. Thank you
I have a video up where we used nitrous as the intercooler-it is not very effective as a cooler-but does add lots of power
Power was still clearly climbing on that 4.8. Can you do "big rpm" LS test for us in the future richard? See how far we can really rev these things out? Id like to know where that cam made peak power on that setup! -thks as always!
the valve train limits rpm
Love when he talks about nitrous!
Thanks for all you do Richard
Funny thing at the local races 2 weekends ago...the vehicles hit won in the Pro & Sportsmen classes were both carbureted engines , one was nitrous pro was turbo
Love your videos. You should show the process on how you ring gap an LS that would be great.
Love to see this cam 54-545-11 on 6.2 LS NA and boost.
My tuner recommended this cam on my 6.2 Ls for daily driving
it works well on a 6.2L
I have learned some about a ls got a pretty clean car 2002 trans am not a ws6 but I got it pretty cheap it's black tooim really a big block na carb now I'm switching to ls motor I have learned quite a bit from you a usually watch many times to sink in my head I'm a gear head so I learned a lot faster than most absolutely love your show your the man but I have this new ls project so I'm going with the lq4 like the block in my truck so thank you for doing all this work I hope that you are making good money bud you deserve it for sure I have some motor part heads came if square port heads 408 I know it will come out 600 hp range but would like to use turbo or pro charger thank you again for commenting on my post your the man brother.
Really like all testing that you do.
Awesome, broad video!
Would love to see you play with an Vortec 8.1L
yes
@@richardholdener1727 hi question, planning on street build i have a chevette 1,600 # 12 bolt. 373s coil over 4 link
.. Ok my question is what will be my best engine option 4.8, 5.3 ,6.0 want it carbed. ?on that class weight what route should i go ? horse power range ? , not for racing at the track but fast enough for highway thanks in advance speeds
Loved the video. Keep it up!
Single plane all the way on any ls engine. I ran a dual plane on a stock 5.3 & 4.8 with a comp thumper cam. Both ran like garbage with horrible dead spots. Took the dual plane off the 5.3 & put a single plane on & ran awesome way more responsive & power everywhere you want it. The 4.8 I actually cut the center divider out & added a 1" spacer & fixed it. Basically making similar to a single plane....just buy a single plane.
Love it
Back in the day, a built, balanced and blueprinted 283 Chevy, tuned would not only scream on high revs but it could tow a heavy car.
Sure but at a higher rpm down low even with no upgrades the 283 was. Certainly not much in the way of low end torque but ran so smooth and I loved them I only actually had 2 one that was In a 67 impala with a powerslide and it ran beautifully and the other was out of a 65 something I'm not sure of I got the motor after it was pulled the 67 went in my girlfriend's 72 Camaro with the only thing done was a krylon rebuild and an H.E.I distributor in front of a turbo 350 instead of the powerslide it really woke up even with the small little two barrel it came with I hounded her for years to let me put a four barrel headers and dual exhaust on it but she wasn't with it she kept saying why so you can beat on it and of course my answer was nooooo just so it can breath better and you'll get better fuel milage ( lies lies lies ) lol that small two barrel sipped the fuel lol anyway we broke up she sold it and I never did ever get to see the potential of a stock 283 with just some small upgrades like a 4 barrel and a free flowing exhaust I assume like any other small block the valve train would be the limiting factor for the Rpms which it really needs if I'm not mistaken and being a small journal motor could with the right heads not too far away from. The output of the infamous 302 so the stroke is a bit shorter it still would spin to the stratosphere and make ungodly power if it was built right but man it's really something you have to get used to the two 69 z28s I rode in were such screamers you'd swear it was about to blow up every time you ran it hard as I said it's something you have to get used to and get that God it's revving to death out of your head lol 7 grand is to your ears a whole different world than the 5 grand or so the average 350 sees but those small journal 283 302 and 327s loved it and lived to fight again another day if they had the roller valve train components we have nowadays holy hell they would really survive to fight another day from what I've been told that's what was the first to go not the bottom end the bottom ends held up just fine even with the oil pressure only at ten ish at idle and 50 ish at higher rpms
I love the 283-but even the very best one makes a lot less power than a stock truck 4.8L
Absolutely and to make power you had to spin the snot out if it hence short stroke motors shortcoming is just that issue whereas the 4.8 has a decent stroke and bore combination to get the best of both worlds along with the best cylinder heads to ever come off the assembly line and just the overall design taking 50 years of experience with small and big blocks and using that knowledge to make the ultimate small block engine moving the cam tunnel and allowing a larger overall cam diameter changed the game entirely they have profiles now that allow smooth idle with lots of vacuum at idle and and scream at full throttle which was unheard of and impossible actually before ..
Love the videos! Keep’em coming 😆
one for your "other guys" nissan vk56 :)
The guys down in AU, LS1. 🤘
Dude you are the best!!! Thanks for the videos bro
And I’d like to see a 6.0 carb to with those set ups
that was great in a 4.8. a cam swap to 450hp? wow. around $4500 for 650hp thats pretty good. torq storm 2900$ easier to add the torq storm than a turbo. can bolt it on in the driveway in about 4hours
Never heard whether or not you gapped the rings or not.
Right on
Would be cool to see a twin turbo cross ram test, how would it work out having each turbo feed its own throttle body
Though naturally each turbo and bank should be on par with each other, it is is probably better to have balance.
I want to see some regular guy comparison of the 5.4 mod 3 valve vs the 5.3 LS with similar mods. Then a 5.4 junk yard with junk yard 4 valve heads added. Where I'm located the mod motors sit and the LS motors get bought up. I theorize that 3 valve heads can perform well vs the LS head
I spray my 4.8 with a 150 right out the hole. Damn thing doesn’t make any torque and it needs it! Especially in a truck.
Oh fuck yeah straight out the hole only way to do it 💪🏽
What is your combo in? And what are your times? I'm working on a gbody project and could use the info
did you gap rings or not even look at them? and if my eye serves me correctly this is a gen 3 yes? (insert "he did it" meme form Jurassic park)
When in doubt, lean it out!!!!!!!!!
Awesome videos!
Thanks!
I'm going to have to make a trip to my local Propane dealer to find out what kind of tank to use for me to use liquid propane instead of gasoline or E85 with a nitrous kit. I think Frost on the outside of my tunnel ram would be a very cool thing to see.
I've seen LP on diesels never seen it used on a gas engine.
@@Phil-rs5wl My thought is this, by using liquid propane with the nitrous you don't have to be concerned with the cars normal fuel system since the propane is self pressurized just like the nitrous. It's also equal to or better octane ratio VS E85. It should be no more difficult to install than a regular nitrous system yet be able to produce more power, it also lowers the intake temp to freezing levels.
I need to learn more about the direct injected engines because if they can be converted to inject liquid propane instead of gasoline it could be awesome.
If youre really worried about it, I would use M1 as the fuel for your spray. Methanol is a heat sponge. Guys with roots blowers will get frost on the side of the case under boost. Propane works but doesn't take much more than typical gasoline to evaporate. It's about 40% higher than gasoline but a little more than a third of methanol. Stoic for methanol is also 6.42 where propane is 15.5. At stociometric air fuel, propane has 15.7% the latent enthalpy of vaporization as methanol. Given you can use vinyl tubing to hold methanol and not some high pressure line with high pressure pump to keep it liquid. If all you want is frost on the casting, methanol is an easier and more effective way to do it.
@@timothybayliss6680 Have you ever filled a propane tank???
If you have, you have seen what happens when a pressurized liquid evaporates into a gas in a hurry. Methanol does not come close.
Richard great video! I have two 6.0's both going in cars soon but I'd like to run the VS Racing Turbo! Can you refer me the link to where and which ones you used in your test videos? Thanx
7875 gen 2
lets see some more 4.8 (love them) I sill want to know how much exhaust system effects the turbo power numbers like running exhaust pipe and reducing it for mufflers to be used on the street engine, the dyno engines with the turbo has a 4 inch exhaust most cars can not run a 4 inch pipe to a muffler not enough room and the law don't like straight turbo exhaust out the engine compartment.
did you watch the turbo exhaust video?
Run a full exhaust but put a cutout right up front using 4 in up to it then either do fender dumps or just dump under the car right up front. Then you get the quiet exhaust when you need it and the open exhaust when you want it.
@@richardholdener1727 no
@@Phil-rs5wl Thanks Phil
@@tpeace2160 I've seen one guy with a boost referenced cutout. It was on a neon turbo or whatever they're called. Fully open by 5psi and less that 1/2 second to open. Quiet until boost. Worked good.
Great video
you should do a 4.6 ford, 4.7 mopar, 4.7 Toyota, 48 Chevy shoot out.
Have you done any videos on the powertech 4.7 mopar motor? If not will you consider doing a mini big bang episode to see what they will do?
I've got a question about your comment on carburetor versus EFI on the LS and season 1 episode 2 of engine Masters they had a real problem using a Holley Terminator self-learning EFI on a dual plane intake and wound up having to go to a single plane intake, did anybody ever figure out why that was, as always, love the videos, definitely keep testing, I learn something everyday
Yes if you use a 1in spacer it can read both sides of engine for a map
I am not a fan of the self learning throttle body injection
I have a sniper efi tbi and works good on My 401 amc
You should try the newer 4.3l ecotec see what is horsepower and torque just engine only
Your a legend now sweet
Yeet cannon!
Getting there! .1 cubic inches away from a 4.7 HO
Still would like to no carb jetting with blow throw carb just for starting point.350 stock or very small cam488 liftish and 8 pounds of boost
Its called a 4.great richard
All Turbo ..lol ...good stuff man ...change the rods with stock pistons and let's see what the 4.8 can really do ..more ...power Baby lol
look up Big Bang
Can you talk about durability? It’s cool to see numbers, but I have no experience with the longevity of a blown junkyard 4.8. I think that would attract a lot of attention’
I can't test durability on the dyno-I have made 70+ pulls at 1,000 hp on several of the big bang motors and several hundred runs on the Gen 4 6.0L big bang motor-they work and last if the tune is right
Would love to see big bang on a vq35de out of a 350z 🤔
The vq35 will bend stock rods and send them though the block if it makes over 650ish ft.lbs before 5k
@@ericmaysonet3135 would still love to see it
You should really test intercoolers VS no intercoolers on the higher boost applications
always intercoolers
I’ve been running the 54-454-11 cam for a week now. I love it, it does steal a lot of the vacuum from the brake booster. What do you recommend for that situation? I tried the vacuum canister it helped but not enough to get a inspection done.
What about using a factory electric vacuum pump off a 03 or 04 pickup?
J Minnick I’ll give that a try I’m thinking my lash might be too tight. I was running out of daylight when I put back together and rushing. If that doesn’t fix it I’ll try the electric pump.
Or a hydroboost off the ps pump.
That's right
There were 2 vortec 7400's in the late 90's. One used a distributor in the 2500 and 3500 series trucks and then in the top locks and Kodiak the other used a coil near plug design. Is the big truck 7400 similar to an LS?
Edit: Is the L21 similar to an LS type engine?
only in use of the coil pack and tuning-other wise its BBC
Vacuum cleaner at 7:30? I thought it was in my house.....
Hey Richard, many videos ago, you ran that same carb/blow through adaptor and experienced a lean condition on one side of the engine. Did you ever solve the lean condition?
fuel supply to the carb
I have an LS1 and I'm in the states lol
HEMI’S! Why don’t you do this kind of testing with 5.7 and 6.4 mills?!! Please!!!!!!!
please watch the Hemi videos that R up
When you guys run e85, is it pump e85 that you are running or you buy jugs or barrels of e85?
I go buy it from the pump at a local station
where are the NO2 and boost numbers? The title says NO2 and boost but I did not see it in the video...
we ran the motor with N20 AND we ran the motor with boost
@@richardholdener1727 the title implies both boost and NO2 we ran in combination. Other viewers have the same opinion.
So I camp and go to the dunes a lot. I have a 5 speed 2013 4.8 silverado with 65k mileage. I travel down and up the mountains on the freeway and my 4.8 needs more torque power. I'm not thinking of review my motor past 5500 RPM whats the cheapest combination for me? BTR Torque cam and programing? What benefits am I looking at? Or cheap ebay turbo and programing?
-4AN Line is only good for 300ish shot.
-6 will show you the limit of a stock small block.
Do a test and prove it.
At what RPM would that HP curve nose over hard ? because of the rising boost curve I am imagining that little 4.8 would spin to the moon ! 8500 rpm ? Lol where is the limit ?
limit is valve train
Is it possible to read fuel flow on the dyno and then compare fuel economy from stock vs modified at the same torque points?
You need a really accurate fuel flow meter. You can scale fuel usage with pulse width and lambda but that really only works well with back to back tests. I also don't know if the brake on the dyno can hold the engine at 0rpm per sec. For fuel efficiency testing you want to do sweeps with like 15" of manifold vacuum starting at 1500-2000rpm. Westech can probably do it, but it's a little outside the norm as compared to slamming a cam in and spinning the engine to 7k.
That is best done on the road under cruise
Was only thinking because an old cammed up v8 would typically get worse mpg, but a newer alloy v8 with higher comp and efi it might not. But definitely boring compared to seeing junk make big HP 😁
new guy here .. where is your chop located?! love your vids
I don't have a shop-nor do I sell anything-just info
Richard Holdener thanks for replying .. can you give me some pointers .. i have a 04 silverado 4.3 v6 but i’m installing a 5.3 next month .. i want a daily 600hp driver .. what can i do to have it reliable .. i drive about 120 miles a day .. also love your channel keep up the good work 😎

What did you gap the rings to
Was the engine ran with 14.6 psi? That amount of boost should've doubled the power minus "some" power to run the supercharger. To go from 441 hp to 672 hp would/should need less than 8 psi.
thnx
id like to know how much hp it takes to drive the supercharger thru the dyno pull
depends on the blower type and flow rate/boost-some cost as much as 300 hp
Mr Richard can you do a L77 6.0 please
lots of 6.0L vids up
👐👍
Where is the boost + nos at the same time as advertised? .
we did run NOS and Boost and a cam
Are the "seesaw" connectors on roller lifters a necessity?
I'd like to modify some roller lifters for an inline 6 that doesn't have siamese lifter holes.
What
@@austindoud273
I have an inline six that no one makes roller lifters for because there's block webbing separating the lifter bores dramtically. I see those bars/rods that connect roller lifters as sets (seesaw) as they're called.
They stop the lifter from spinning around. It the wheel on the end of the roller lifter turned 90 deg to the cam lobe it would wipe the lobe off. Some late model engines run a cradle thats fixed to the block, that may be something you can modify. Hope this helps.
@@wakjob961 oh the guy below spelled it out typically called tie bar you could Do like a sbc with the dog bone or even maybe some d shaped bushings in the lifter bore along with appropriately shaped lifters good luck
Richard, how much boost was this setup?
gauge showed over 14 psi (I think it was wrong)
Hey buddy what’s better d581 coil packs or Ls1 coil packs
I have best luck so far with LS3
Richard Holdener thank you buddy
For what i have into my diesel i could have more hp with 5.3 for 1/2 the dough
The more Nos the better till the rods come out. lol
Can u tune a small turbo diesel next Rich?
we don't run diesels on the engine dyno
@@richardholdener1727 Thanks for the reply, ive seen loads of people talk up diesels have a great day.
WHATS THE STORY ON YOUR CAM BUSINESS? (Sent with love)
Was that all stock internals ?
31 seems high for timing on an ls.
Is this because you are using a carburetor?
Timing mark could also be off
we adjusted til it stopped making power-don't care what the number is
I've done a couple carb ls motors. They seem to really like more timing. My last carb 4.8 made the most power NA with 35* of timing.
31 isn't particularly high. Ls2 guys usually have really good luck with factory thermostat and 27-28°. If it was run at 160°f and it has 9.4 v 10.5;1 compression that's enough for 3 degrees of timing. It might sound a little much but it's in the ball park.
So where is the NOS + BOOST ????????
You said boost and nitrous. Looks like you ran them separate. Why don’t you ever run them together
afr’s race gas vs e85??
was the same
How much would an intercooler add to the supercharger/
depends on boost level and air temp
Carb guys can't tune efi and efi guys can't tune carbs. Thats why the hate lmao
I can tune both. I just prefer efi due to datalogging/traction control etc.
all the stock 4.8s make 330 hp the single plane dosent seem to hurt .........
it hurts a lot down low and in the mid range
Personally I blame squirrels
what is that supposed to mean? I have seen people saying that for a while but don't get the joke.
