- HOW MUCH POWER WILL CAM AND SPRINGS ADD ON MY LS? DO I NEED A TURBO CAM TO RUN BOOST ON MY JUNKYARD LS? HOW DO I MAKE MORE LS POWER? CAN I ADD A TURBO TO MY JUNKYARD LS? WILL A 4.8L WORK WITH BOOST? HOW MUCH POWER DOES A BTR STAGE 2 TURBO CAM ADD? DO I NEED TO REPLACE THE SPRINGS WHEN I SWAP CAMSHFTS? WHAT SIZE TURBO SHOULD I RUN ON MY CAMMED 4.8L? CHECK OUT THIS VIDEO WHERE I COVERED THE BASIC RECIPE FOR MAKING SOLID LS TURBO POWER, CAM, SPRINGS AND BOOST! STARTING WITH THE NA MOTOR, I REPLACED THE STOCK LR4 CAM WITH A BTR STAGE 2 TURBO CAM, THEN ADDED BOOST FROM AN S475 TURBO FROM SUMMIT RACING.
Am I the only one that hits the thumbs up button before the video even starts?...my go to guy for knowledge and performance!
I just did it 😂!!
Do not care if he is schooling us from a Dodge, Ford or Chevy I have my seat.
I do it too
I do the same thing
I'm actually terrible at remembering to like videos.
Thanks for the reminder
👍
Just got my Gt45 junkyard 5.3 up and running, its an absolute BLAST on only 8lbs for now.
Thanks for the motivation Richard!
That's Awesome!!
Nice! Where did you buy your gt45 from?
@@carlylemcafee5483 ebay, just make sure you find a seller with good feedback of course
How much power is it making on 8lbs? I wanna build a turbo junkyard 5.4 aswell
@@Julesdapimp not sure, should be close to 600 fly wheel
Remember for you budget guy there are some great junkyard/ budget oem injectors, some Volvos use 41 lbs injectors and bigger, 8.1 have a little bigger injectors, you can decap some stock truck injectors, a friend of mine is running 2 junkyard fuel pumps and decapped Volvo injectors, most 1/2 hard line some spots are still 3/8s and is making close to 700
Do he have videos of doing that 😳?
@@youngbuckrefrigeration716 I’m not sure but sloppy mechanics has a video on deccaping stock injectors to gain about 100% fuel flow, the idea is you get 2 good sets of injectors decap them all and then send them out to get Them flow matched
GREAT VIDEO RICHARD. CHEAP HORSEPOWER IS THE FOCUS. GREAT VIDEO AND THANKS FOR SHARING. SOMETHING TO CONSIDER.
Hi, hope all is well. Video idea. Compare the BTR truck Norris cam…. With the NSR Truck Norris cam…but don’t upgrade the springs on the NSR cam…. Also maybe compare other NSR cams w stock springs.
Before anyone asks, same applies to your 6.0 and 5.3
Lol. Thanks for clearing that up for some folks.
Thank you 😂
I’d love to see 4.8, 5.3 and 6.0 graphs with identical cam and turbo layed out next to each other. It would be an obvious illustration of what displacement is doing on the same setup.
PLEASE SEE THE VIDEO WHERE I COMPARED THE STOCK 4.8L, 5.3L AND 6.0L
Boost is your friend...and even more boost is your best friend...
What about oil pumps ?? Looking into the melling high volume one .
You should revisit this with a true divided hotside to show the improved boost response.
Boost makes everything better
Decap stock injectors and they flow 72ish lbs at 58psi base. Can run a small amount on E85 or a pretty decent amount on pump gas that way.
as long as they all flow the same
thanks for answering questions even in the first 2 minutes, I also loved all your old articles in muscle mustangs and fast Fords! Is the new 7.3 gas motor something to be excited about?
YES
Hey Richard could we do a dyno result test on the old school cool cans. May I on fuel injected and carbed, ice vs dry ice. I seen allot of conflicting information on this topic. Btw ur vids are the best!
I love the fox mustang I might have to switch to chey
I probably missed the video? Hot sizes house size! Haven't seen any video of same set ups over different sizes hot side. 1.32 etc
I'VE DONE AR TESTING WAY BACK
That's my exact setup in my 68 c10
Now when talking about a junkyard 4.8 and putting gap on rings with forged pistons. Are you using the stock connecting rods and all stock bearings? Or is this a rebuild with the honed bores, new bearings new timing and so on. Just curious if the testing was just throwing a few pistons and cam in and bolting on a turbo then sending it to outer space
we run turbos on stock motors with stock pistons, rod, crank and block with just added ring gap. Also with forged internals
Thank you
Are you going to continue to use the sloppy best cam for testing or was that a one and done situation?
Just curious, does switching to e85 hurt the seals and gaskets? 👍👍
On the last pod cast you mentioned about long/short tube runners. Any videos you did on maximizing them or videos out there I can watch?
6.0 LS p/u looking for turbo for towing power, what I need to do
FOR TOWING-JUST ADD BOOST
Any fuel pump recommendations for a 4.8 with 1000cc injectors?
what power level?
@@richardholdener1727 twin 62mm turbos, tsp stage 3 cam and dual spring kit, Holley 1000cc injectors
Everything else completely stock(motor,trans etc.)
Going for a daily street truck 550-700whp
Fairly new to watching your videos, would higher compression make a drastic power difference? Bacially doing same setup on a 6L but running at 10.3:1 comp?
Yeah, it's gonna make more power with more compression. Adding boost is the equivalent of adding more compression, so you will need less boost to get the same output as the guy with less compeession
Hey Richard, I am starting a build, it currently has a low mileage 4.8L. I ultimately just want a nasty little street truck, but i also have a l92 and 6l80 that i was thinking on swapping but both engine and tranny will need to be rebuilt because its higher mileage. Any recommendations? I think 600hp at the wheels would be a reasonable goal for street use, but would want the ability to crank it up if needs be.
turbo and 600 whp is easy
if you had the choice between the 4.8 and 6.2, which one would you choose ?
a 6.2l would be aluminum and bigger so I would pick that if the price is the same (usually not the case), but most would pick the cheapest route to make an easy 600 hp (that would be the 4.8L or 5.3l)
Please do the same video but with hemi 5.7 sub 2009 non vvt
please see the hemi turbo vids
On all of your cam and boost LS vids, are you still running factory pushrods and rockers?
Would you recommend dual springs with a stock cam and boost?
no-beehives will work
.... Would running ethanol free gasoline, E90 around here, gain or decrease power outputs? 🤔
U mean e10? Regular pump gas
Id like to see this same test with the same engine setup but with different brand turbos. Say what are the results with an ebay gt45, on3 gt45 and such. How the quality of the turbo plays a factor in the boost level vs the power and torque. "Cheap turbo makes 10 psi @ 5500 rpm vs higher end turbo makes 10 psi @ 2000 rpms" Also do it with ball bearing vs journal bearing. ($100 vs $500 vs $2000 turbo) is the "you get what you pay for" worth it... you see alot of twin gt35s and gt45s in the LS community but is it really worth it to go cheaper or spend the extra few hundred for the name brand and size it better to the setup say a 76/75 vs the gt45.
you will see very little difference at 10 psi
@@richardholdener1727 I was just saying 10 psi as a reference. Basically what are the results with a higher end turbo vs cheap and bb vs journal bearing. If you put a manual boost controller on it how quick do they "light up" at the set psi and how effective is the power and torque curve. In a nut shell what to small of a turbo would do and what an over sized turbo would do to the setup.
r@@richardholdener1727 rick for the BTR stage to cam do you need more valve clerence and for the spring any machining or juste fit ,,,,,,tanks for all your time ,,,merci bien
Are 1000 cc snake eaters injectors good for 1000 hp on e 85 on a turbo 5.3
YES
@@richardholdener1727 thanks buddy
the description is missing the "add ring gap" disclaimer
.007-.008 ring gap per 1 inch of bore per Sir Cam alot or .028 on 4 inch bore
@@408SPLKINGS I gap cast piston at 7tho per inch forged at 8.5 tho per inch also make the a bit extra especially for 26xx and the stronger more ductile pistons have higher expansion ratios this is way they get a lot of slap when cold.
But if doing a ls junk yard boost build just air for 28-38 tho (5.3 to 6.2). And it will do fine you will hit the rod limits before they get pinched but maybe add another 4-5tho if not properly cooling charge air.
Maybe i missed it but was the comp mentioned?
9.8:1
Thank you, everytime, thank you!
What would you do for fuel; in a boosted situation, if e85 isn’t in your area? The closest e85 pump for me is 2 hours away.
run 91 with less timing
How long does that carry over 7k rpm
How was the soccer game?
not the hoped for outcome!
Test 2v heads Vs 4v heads on the same block
and intake and cams-they will all be different
Awesome video's
What kind of timing were you running under boost?
22
@@richardholdener1727 how much world that be with 91 for example? Was that at the 12psi run?
C+S+B...Got it!
seems simple, right?
@@richardholdener1727 When you say it. I learn H+C+I from you. heads, Cam Intake. This one is Far better...less Expensive! More Power...Thanks Richard...
# 1👍🏻! 💪🏻
What push rods did you use? Stock 7.4?
we measure and adjust
Good shit Richard
What about exhaust valves ? There is a superalloy exhaust valve for virtually everything now .and with girthy valve springs ,comes elevated oil tempature at least in the marine app's. Street guys don't talk about as much though
Thank u for all your research 🔬 love the Chanel. Can u guide me in the right Direction to build 800HP on my Mercury marine 1999 454 mpi mag I already have a M-1 pro charger pushing 5psi. What cam and valve springs would help me accomplish 800?
YOU WILL NED MORE THAN A CAM
@@richardholdener1727 I forgot to add that my pro charger has a water inner cooler. I believe I have the upgraded injectors and fuel pump as well. I was wondering if I could get close to 800 with some head work and beehive valve springs and Cam and maybe change the police so I am making 7 pounds of boost 🤔
Wonder if anyone has used a thumper cam with boost
Every cam is a turbo cam.
And ring gap
Why e85? The normal guy is on 91-93 gas. All you do is e85 or race gas.
use the fuel you like
👍🏽🇺🇸👍🏽
What happened to the video? 12 minutes?!
Personally I blame squirrels
hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahah omg hahahahahaha man thats the line of the century.. man you got some mileage out of this one.what a side splitter..family has to be proud
Hmm, that's weird, my bone stock Coyote mustang makes way more 🤔
Are u using Holley software?
