TURBO LS COMBOS-WHAT WORKS (TRICK vs TRIED & TRUE) 

I love this. No brand loyalty, no sponsors being stroked, just hard numbers.

richard, the fucking treehouse is my favorite

Criminally underrated channel. Needs to be at least 500k+ subs

Get your hands out of your pockets Richard, embrace your physical characteristics. Please don't become self conscious about yourself because us winding you up about speaking like an Italian 😉😂😂😂

Moar, turbo

Sloppy stage 2 cam with that s475 and a tbss intake would be pretty cool also

The “KISS” principle! Keep It Simple Stupid! Definitely the best way to go!

Can you do some turbo tests with a stock alloy 5.7 LS preferably with twin china T3/T4's, Crow turbo cam and springs. Interested coz I've installed the Alloy LS and I'm in the fab stage of every thing else. Would be good for extra info to size stuff e.g. converter, injectors, etc.

Na “trick” combo. I love the use of the word trick lol. Reminds me of so many old school ppl I know. Hell I use it lol

Great video. Love the 4.8 stuff a real poor man's combo. Other then that turbo. Lol. Your a great teacher and keep those videos coming

Yes, i know a the high compression had more power, but I went with 317s (because I had them and they were ported)(ss2 cam and s475) my thought was because it’s my daily and in northern Washington, Idaho, Montana e85 is hard to get I’m running 92 octane. So question given a fuel octane restriction would not the better flowing low compression but higher boost end up making more power in the end? Yes I agree the 706 heads would be more responsive (my pickup is a dog to 2500rpm)

Very interesting. I would love to see a similar test done on a different engine platform, Or even a roots blower instead of a turbo. Mismatched parts is easily the most common cause of disappointing engine builds.

Solid video. Richard, what intake have you found to be best besides stock for the 4.8 ly2 lr4? If there is any. It’s like less is more!

Best edition yet! 4.8L don't BS me test, ironically shooting down all the stuff that bs's everyone! Numbers are numbers especially when the internet has its way with them, but this is proof and these are facts.

Could have sworn i was listening to Happel “get a cheap 4.8, do nothing to it, 78/75 or S475, make power” lmao

You brought a ton of knowledge and information to the RU-vid community keep doing what you do best! 👍🏻

Keep them coming, I’d like to see a small charger comparison on 6.0/6.2 , Currently working on a lq9 with single 66mm on pump gas no intercooler for a rock bouncer. I don’t live at 6krpm and want my buggy ti lite down low

Another tremendous video full of great info! Best channel on RU-vid!

I want the karate chops back Richard, it's not the same

Congratulations on 20 k Subscribers Richard. Thanks for all the Great Videos. 👍👍👍

More $ and it's kinda "stupid". Welcome to living in a socialist state. 😝 Glad I'm in Texas!!!!!

Can you do a video of something that we never get to see like a old school Mopar engine like a 440 and see how much boost or power you can make before it blows you know something we never see an old school Mopar and do you recommend getting your engine electronically balanced or you think that's not always necessary when you going over a thousand horsepower

Cali is expensive? A 5.7 is $1100 annual tax and gas is $7/gal. in germany.

Hey Richard I have two holset hx35’s Laying around do you think they’ll do fine on a twin 4.8? Also I have an HX 55 And Two Garrett GT 37’s they were all donated But my dad is most likely going to use the 55 on a 6.0! Just kind of want your overall opinion on those please and thank you

Personally I blame squirrels

Bring the hands back again! We all miss it!

But but but that intake is shinny, and that cam was only $50 lol. I hope you can read the sarcasm in this.

I don't know how to explain this to you other than what I'm getting ready to say I want to be able to switch tanks pump gas the good yes I want to be able to turn heater blows up from inside the cab I want to be able to alter my timing from inside the cat not looking for a race car or truck just want to have control of all of that while in my seat

Excellent video! That "trick" one wasn't even close to peaking at 7k rpm ha

Cable actuation electronic programming actuation in my mind I can see its capabilities in about 10 seconds moving that direction

You should compare the sloppy stage 2 vs the stage 2 turbo cam on either turbo

Listen to someone on the internet? Your on the internet! Just kidding. Love your stuff!

If all things are the same except 706 vs 317 heads, I wonder how they compare with boost when the limiting factor is 91 oct. The 706 makes more power NA than the 317 because of the compression bump, but that means the 317 should be able to take more boost with 91 oct.

25 Years ago (before the internet) An engineer by the name of Red Armstrong preached the same sermon to the Turbo Buick crowd...and I listened. I followed his recipe, and bought his upgrade parts. Great advice !!!

How about that 480 on the better motor? The higher compression and proper cam should help that big girl light off of my thinking is correct?

Richard I am hooked on your videos now to my question I have seen your video on boost on a SBC with a roots blower. Have you ever done a test with the cx raceing SBC turbo kit blow through on a holley super sniper 4150 I am thinking of building this set up any advice woud be great

i have ben reading your articles for years now your on youtube to those of you who dont know this guy you should listen this guy is the real deal i was just reading an article in hot rod you did about bbc ovel vs square port heads great to see you here

For the people who are thumbs downing 👎🏾 these videos just don’t watch it because you’re a hater!!

I like the video’s Richard on the 4.8 , 5.3’s. I’m still waiting on the LQ4 torque video’s

Want to turbocharge my 383 stroker. What about us conventional guys lol

I have a 2015 l96 6.0 stock. My plan is to use a gt45 and demon blow through carb. Will be installed in my 79 fox mustang for drag racing. What other cheaper upgrades would you suggest?

How many of us can drive thousand horsepower ?

Whats the part number on that s475??

When you gone do the Direct fogger nitrous 5.3

Please add the toyota v8 1uz or 2uz fe engine there in American junkyards out lasting the competition

There's nothing wrong with that LSA cam if you size the turbo right. Its just more street friendly.

Didn't hear anything about gap on this one?

Ok so I've been thinking and you know what would be a really interesting comparison? A bunch of engines of various types and setups and the volume of air they consume. I'm talking na, turbo, procharged, big block Chevy, ls, hemi, whatever Ford stuff and compare the volume of air they are consuming at various power levels and how they relate. How much air does a crazy na big block Chevy or hemi use at say 1000 hp compared to say a turbo or supercharged ls or 2jz at the same power? And fuel too. Does it come down to a similar volume of air flowed with the proper amount of fuel equal a general same amount of horsepower?

What's the size of the hot side on the s475? I seen they have multiple sizes hot sides, think most was 1.32?

Great video. Thank you much

Would have loved to see the s480 at 16psi

I noticed you didn't mention any fuel upgrades. Were there any? Stock fuel injectors?

More compression equals more torque and helps that turbo spool faster (especially when sized correctly).

Thanks Richard for your videos

Just the way my brain works

Did you do anything with ring gap?

I really liked this comparison

So, why isn't Brian Tooley Racing a sponsor on these videos?

Great video as usual RH! I read all the hot rod magazines back in the day. Like ALL of them. Especially loved MM&FF. I read every one of your articles. You and Revvin' Evan were my favorites. And LL Brule-J, lol. Freiburger and Finnigan too! Such great memories learning the ways of the horsepower junky! I've built a few cars, several engines, couple bikes. I am a driveability tech at a Chevrolet dealer in Texas. Thank you for putting this all together. So many videos coming out so quick. Amazing. I noticed you haven't put any gen 4's on the dyno (I might have missed it.) Should they be avoided? I know you have the gen 4 rods in the 4.8. Have you tested any gen 5's? Those high compression engines have some sweeeeet looking cylinder heads. Keep up the good work Sir!

Why do you always limit rpm and boost in your tests? 16lbs? 7k? On a 4.8? The "big names" in the SBE world are running 8300 rpm on factory heads and 30-40psi. IMO your "wrong part combo" has more potential in an SBE. It will limit the cyl pressures around pk TQ keeping the SBE alive at big power levels. The aftermarket short runner intake will perform much better up top. Where it matters in a race application. And limit power down low that will bend rods and shatter ring lands. Would be nice if you stepped it up for us and ran some rpm and boost through these engines to show what they are really capable of! The big TQ setups will grenade themselves at huge boost levels in actual race applications.

I cant wait to see that video of why 2 turbos are better then one....are they? Hmmm

Hi what size twin turbos would you suggest for ls stroked to 408 With Frankenstein racing heads running twin charge coolers And what power would you expect Have you done a similar set up on your channel Thanks Tim

Myself and the squirrels are curious on what the twin turbo equivalent to the S475 would be . What's a half of a s475 ? T3/T4 twin or something ?

What size turbine housing is on the S475? Or atleast what’s the optimal size for this truck style setup?

What about going even cheaper on that tried and true setup and running a stock ls6 or ls9 cam in say, a 5.3? Only asking because that’s exactly what I have and want to know what kind of power that and the infamous eBay turbo would do😂

At the 825 horsepower level do you need more ring gap?

Witch sort of motorcontroller do you use Ignition and fule

On a large single turbo application would you run a twin turbo cam because you have it or buy a new single turbo cam? What’s the difference?

Good video 👍 Would you ever do a blow through carb vs EFI test ??

Please do the L83 and even LV4 (baby Stage II Buick). they're starting to appear in junkyards fairly cheap.

KISS theory in practice here, shunning the internet keyboard warrior know it alls. Richard, did you have to gap rings on this mule?

It really comes down to the application I talked to you on FB about my old 4.8 setup it was a 2011 4.8 sbe I had decked PRC CNC'ed 799's LJMS cam and BTR springs trunion upgrade ls7 lifters good pushrods a summit brand 102mm fabricated intake and TB with Bosch 210s on ignite e90 in a 3300 pound 99 z28 with a Huron speed single t6 turbo kit with a really nice water to air intercooler I started with a s475 t6 1.32 exhaust basically throwing the beans at it and not picking up power so I threw nitrous on it a single fogger nozzle in the charge pipe and ended up goin 5.60's in the 1/8 a good deal came up on a billet wheel s480 same 1.32 exhaust side I also went to a 5" hood exit to a 4" bumper exit Exhaust and made a converter change and out of the box was almost running what the s475 was running with spray (the converter did help but it was mostly turbo I got curious about methanol injection so I put my nitrous fuel solenoid back on and added another fogger nozzle in the charge pipe and ramped the methanol in similar to how I did with the nitrous on my Holley hp setup and went 5.63 first pass out with the methanol it ended up goin a pb of 5.53 @ 124mph crossing the line at 7886 rpm it was a mean 4.8 but got stupid and trying to go faster I put the spray back on it first pass killed it before the 330 but if you was to run that setup on the street it wouldn't be all that fun until 5000-7800 rpm and it would probably be a good idea to keep the nitrous especially if it's in a heavier car lol but I love 4.8s il take one over a 5.3 all day

I'd love to see a video addressing turbolag. I've done some of my own analysis on cars I deal with, and I see it as ! mostly a perception related to the if torque increase that boost produces.

I thought 706’s got higher compressior since it’s got smaller chamber volume compare to the 317!

I’m just now getting into the LS stuff, I have a ton to learn which is why I’m here. Where does an average Joe go to get a tune to make the cam and turbo work as they should? I have feeling as well 500+ horsepower and a stock 4L60 is on borrowed time?

could you do a test with the summit turbo ls cams ?

Ls9 cam, small turbo for quick spool light street truck? Quick boost to fill in the low end? And the ls9 cam to help with the top end? Just kicking around ideas.

Stock injectors? What are you tuning with?

Why the 15 sec digs? seems like you're trying to hurt it

Love these videos. Thanks Richard

Why does the motor in the n/a video have trickflow heads?

Another awesome test, thanks Richard! Great comparison.

Great video:) ( please keep in mind All my research is for the 6.0) I thought the only compression difference between the 317s and the 706 was if it was an LQ9 verse LQ4 I thought the flat versus dished pistons created the difference in compression with the 317. Though if the 4.8 is a flat piston engine I can see why there would be A substantial compression difference. Thank you teaching us all. Oh I mentioned to you in one of my community posts I had a question I figured you would know / spot

So were both of these motors torn apart and ring gapped?

Where's Your hands?! It's just not the same..

Realizing that I made some typos while voice texting but I think you get the point

Richard is the dyno myth buster awesome stuff

I listen to some guy on the internet but that guy is you haha

I would like to see some 302 , 351w turbo combos.

lsa cam suck on any application.. well in mild lsa build just fine... more less fair would be using ls9 cam.. it aint the best on turbo use but way better than the lsa cam.

Any ring gap ?

A proper setup vs a fanboi setup. The proper setup will win every time. Even the cost of the setup was cheaper than the fanboi setup. Just because it looks cool, doesn't mean it will make more power. Most times, factory intake manifolds will always make more useable power "under the curve" and therefore translates to a quicker, more responsive setup.

what injectors are you running on that e85 s475 BTR Stage 2 combo thats making 800 plus

I like the video you are doing, how about put twins 475 on your 5.3.

Do open the ring gap or just leave it alone on these tests?

ur awsome

Dammit Richard, NOW whos gonna buy my 2 sets of 317s!?!

Nice video

You need to talk more about PROPER SIZED hot-side A/R housings rather than throwing the baby out with the bathwater and simply bolting on a bigger overall turbo in each of your vids.

What was the A/R on the S475 turbo
