Why would you give this guy a thumbs down, who else is helping us come on now

Love it great info. I picked a TB intake based on your info and selected my cam based off your info. With a solid tune on my 5.3 pile it hit 1384 hp so yes your info is gold! Thank you thank you for real info and no hype!

I thank you for explaining this in such a way that it’s so easy to understand 👏👏👏👏👏

You single handed motivated me to do a LS swap to my old Gbody thank you and keep up all the amazing footage

Thanks Heaps, I am choosing a Camshaft for my 740 Turbo Volvo. This video helps a lot.

So tbss intake with the ls9 cam is perfect just as i thought! This is the exact curve ive been looking for! Ill take a slight drop in take off. Ive got 3.92 gears anyways. This video is perfect tysm!

we raced turbo cars in the late 70's forward... in all these years (and getting blackballed by NHRA) this is one of the first guys I have had that actually said anything about compressor maps... Live and die by those maps... and also knows that "bigger" is not always bigger... move that power downstairs a bit and use it there... all about combos

Every cam is the best cam to someone, this is why its important to figure out what you intend to do with the engine, then figure out what budget you realistically have and then you can figure out how much hp you can reliably make, make a plan, set a goal, get a good engine guy involved and listen to him! Thats the best recipe for completing a successful engine build for your project imho

Richard, excellent explanation on how boost just bumps up the curve. So many people out there talking out their tailpipe on Wednesday happens with boost. Well forum "experts" put a banana in that tailpipe! If you don't know, don't speculate, it only hurts the sport. Richie is spot on per usual. He is one lucky bastard to be able to try anything... For cam and intake find the driveability characteristics you can live with. Then add boost to reach desired power levels. Port work and better flowing intake (larger throttle bodies, porting, and so on. You can we the same power with the same cam and intake, just at lower boost levels due to increase in volumetric efficiency. Unfortunately you can only go so far with volumetric efficiency. This is where successful racing teams spend a fortune. They are limited in displacement, rpm, and fuel system. The edge is found in volumetric efficiency. That's not something for the weekend racer or low budget dedicated racer needs to be concerned with. A team made 557hp with a Nissan VQ37 N/A, but how many 370Z's can do that??? Big money research.

Thinking of a Truck application, I would choose the BTR Torque Cam, because when Richard tested it, it "made more power everywhere" which is what you need for a truck. You don't want to give up low end on a truck, at least, if you're going to be using it as a truck. For example heavy towing. Why I need boost is to get my travel trailer up over the I-70 passes in Colorado at a speed that won't get me rear ended. And just all around fun at lower elevations.

Thank you for the the healthy dose of information

The power curve i want has no curve its just 2 straight horizontal lines

I'd think you'd want a cam with more rpm potential (to a certain point) so you could push peak cylinder pressure to a higher rpm. Therefore lessening the chance of hanging the rods out of the block. I'd like to see a dyno test making 1000hp with the stock cam.

I kinda like a more mild cam for the 4.8L and 5.3L! It would have nice torque curve and decent spool up for daily driving! Set it to have a nice rising boost curve with consistent 8-10 lbs of boost to pull strong to 6k rpms and slowly level off and you'd have a serious street vehicle!

You are the master of combo's. All of your work is the best guide for the everyday guy wanting to keep their engine build simple and not killing the wallet.

It is a bit more complicated if you look in a broader perspective, an engine with compact log manifold with a small responsive turbo with high backpressure, no vvt will be pretty bad with badass overlap. Lots of residual gases in the cylinders and it gets knock sensitive, especially on pump fuel. A world away from long tube headers with good pulse separation and massive turbos. So the turbo cam bit depends alot on your engine configuration.

While the power curve will stay the same NA and turbo once it’s making boost, does it reflect how each cam will spool a big turbo? How important is overlap with changing timing and lsa to try keep cylinder pressure up down low to drive a big turbo while still having a fair bit of duration to try get it to make power up top. It’s awesome having someone like you who has tried a million different combinations of what works and what doesn’t and has the use of an engine dyno to show us 👍🏻

High backpressure single turbos need less overlap. Low back pressure twin turbo setups you can tighten the lsa and add some overlap. More overlap will spool faster but may reduce top end power.

Great info.... Something like a sand rail, the short runner would work our great since ya hit max rpm and gear early and the "correct" paddle tire set up slingshots you like a 7000 rpm stall converter... Long runner for toys that shift & run through a few gears and need to pull from mid rpm areas...

Have you ever compared throttle body sizes? Those charts could be interesting.

You should test a stock duration cam with a bunch of lift or low lift with crazy duration

My most used quote of yours is, "There's no such thing as magic cam specs. Similar cams make similar power." If a off shelf cam has a similar spec to your custom stage ~ turbo cam, they will make similar power despite the consensus that the turbo cam has to work better.

thank you Richards ❤

I’m the best person for my set up but I like snappy turbo not lazy so a 212/218 550 550 112 +4 with a big turbo brian tooley says not to let exhaust exit with overlap

Of course drive/driven ratio will play a part in this.

I decided to build my 6.0 into a stroker 408, N/A, it should end up around 10.3-10.5 to 1 compression. What I'd like to have an opinion on, which of these cam would you put in it? the Summit SUM-8710, 230/242 dur 625/605 lift 113+3 LSA or the Comp cam 54-459-11 you are very familiar with (I made made it into a possibility from one of your video 😉)

Have a 4.8 in 2011 Silverado. No dod/afm....but does have vvt, how’s about some testing using factory equipment with turbo and aftermarket cams built for vvt, showing graphs n/a and turbocharged?

I would note, if it hasn’t been noted already that super high torque at low engine speed can put lots of stress on your bottom end. Just something to keep in mind. If you are doing an NA deal, it probably won’t be an issue. But it is with decent powered booster stuff. Anyways. Have a good day.

I get the impression Richard knew all this before he did the testing. It's all about air flow. It doesn't matter what the pressure is, air still flows the same..... assuming the turbo's compressor and turbine efficiency are selected correctly.

I would like to see a turbo header to manifold shootout on and ls. Header vs holley manifold vs stock truck vs ect. All of this done on a stock head and stock displacement so the flow is not effected by a special flowing head.

The thumbnail of you smiling and holding your shaft--- Anthony Weiner went t jail for that.

Richard got a $20K question: If the N/A motor is maxed out and transmission is build and suspension done; what blower will be best for M6 LS3 6.2 vs a 5.0 whipple coyote?

For science show everyone what a restriction looks like in the curve. Like oem y pipe vs duel. Literally something that can effect the two and hp curve of the cam to be different from what's shown to be what it should do

How about a high compression ls6 test geared for the road course track crowd

I have the sloppy stage 3 in a LQ4 , sucks to be me ! The new skool internet says my car will not even run once I add a turbo , too much duration ! Just ask the guys on LS1tech 😂 , and all the old skool guys say I need 7:1 compression and I need to o-ring the block for boost ! Thanks for bringing the truth to the world Richard !!!!

I got a 4.8 s10 cold air intake and exhaust and electric fans it's fun truck and pretty quick .would love to have a cam and springs and a cheap turbo or a 100 shot but I work everyday alot of Bill's and it sucks seeing all these builds but I love it Richard holder you have the best job in the world man I would almost give one of my nuts to do this.lol

When are your cam shafts coming out??

Lower boost is going to be less stressful so id take the highest hp made NA. Most guys will use a 3k convertor minimum anyway. If you're using a stock convertor with any decent turbo you're missing out.

What about a cam for ls3 with supercharger for low end power and a turbo for high end power

i thought you needed to get a turbo cam for something to do with valve float or something but what do i know

I'd be interested to see a test where you run the same turbo with the different cams, but adjust it to hit the same peak HP, instead of the same boost, and compare the curves. Especially regarding the lower RPM's where boost is still building on the smaller cam where it may have already hit the peak boost it needs with the larger cams.

how about any videos or tests for those seeking to peak in the 7-8000rpm range ? Very few seem to peak that high, although some users manage to get to 8k ok ?

I have a question us old 8v 2.2 2.5l turbo dodge guys have argued. Is there any way you could test plenum volume makes a difference in fuel injected Boost application's? I know with N/A it makes zero difference. Some of us turbo dodge guys (4cyl 8 valve) swear a larger plenum is mandatory for more power. I wonder if any platform could be used. So long as boost & fuel injection were used with small plenum vs huge. Thanks Richard your videos and information sharing is 2nd to none! Keep it up!

That crane 224 looks really good with average and peak power, I need an intake manifold that provides equal distribution of water methanol for an ly6 street motor boosted.

Richard can you make a video on Turbo cam vs Centrifugal cam? LS turbo engine.

Hey Richard, have you ever done with a intake rocker arm different than a exhaust rocker arm? Example a 1.7 rocker for the intake and a 1.6 on the exhaust on the same motor. Maybe it makes no difference? You test a lot of combos and maybe you came across this over the years.

How about testing a batch of OEM diesel turbos?

Can you do a difference in power on different spark plug types on a basic to mild build engine

Got any good information on the honda h series?

Great video. Im curious on boost response on LS Ebay twin turbo gt45 vs gt35. Something for the street car guys. I think to many people are concerned with high HP numbers instead of good throttle response on the street. Will you be doing any twin turbo comparison? Big twins vs little on an LS? thank you for helping everyone with the tests. I'll be supporting you through patreon. Ahmad

Great video. So, theoretically could you build a 427" turbo LS that makes a flat 700 lb/ft from 2500- 7000rpm on pump gas? Been thinking about this for a while- a bit tricky since you'd need decent boost at 2500, but not choke it too bad at 700.

You know... something from stock ish to wild. Making good power reliability that you can beat on all day and it’ll live.

Just finished the Oct issue of Hot Rod mag, with You testing Hemi intakes! Please take a look at the latest Cleetus video? They pulled a head, and the carbon on the pistons went from dark to light. Front to rear. What do You think would cause that?

Would love to see 5.7 ls1 videos

I want to see dyno testing on Holley Sniper Race intake on a LQ4 NA . Make it happen Richard!!

Please test what happens when you put a cam in a VVT engine like a gen4 sbc LS.

Still waiting on a 351w blow thru turbo video ! I’ve got a built 357 but what turbo ? Intercooler choice water vs air ?

Your the best

Right on

Also on the factory truck 76mm tb intake manifold I made 474rwhp 428rwtq in my 4WD 2006 silverado It was an iron 383 with 11-1 wiseco pistons, 227cc Dart heads i hand ported that started from dart 205 heads, i used a small solid roller cam 235-240 .636in .643ex 113lsa 110ilc Port matched the stock truck intake Stock 76mm throttle body Pace setter long tube headers Circle D triple disc billet 3400 stall 4L60E trans, 10 bolt 3.42 rear I know the LSXRT would have put me near 500rw NA but Still the truth is the truck hauled ass and ran high 11's

So do long runners work better at low engine speed because the wavelength of the incoming charge is longer? If so is there a way to calculate optimum runner length for a constant speed engine or an engine that will be held at a constant speed while under power? Thinking about that turbo tractor build I'm planning and since it is currently an updraft I was planning on making my own intake and exhaust (plus gives me practice with the TIG so win win) but would like to know how to optimize the runner length without a dyno if that is possible.

Nice F Bomb shirt!!

What cam spec numbers make the LS9 cam down on power compared to the LM7 cam below 5000 ?

I love the F bomb shirt

I just want to increase my lower end power for towing my 8000lb trailer with my 5.3 lmg yukon. What can I do to get my torque to come in sooner than it does? Slap a properly sized turbo on it with a tune and be done? I want to avoid having to change my converter stall speed too if possible.

what about a lt1 cam?

Can you include what injector size are being used

Would a truck Norris cam with turbo work well for daily use?

Hey can you do or have you done sbc with double hump heads and big cam like 525 in 546 ex doing a build and would like to see what I’m working with for street strip with a dual plan

What about intercool intake ? Would the runners matter ? If there’s an intercooler sandwich in between? Like Holley high ram and the new low ram ?

USA USA Gotta love the push rod V-8... From a zillion hours in a N.Y. taxi, to a open class Baja truck, etc... The LS seems to be most easily (and cheaply) built to perform for what ever .... I love my Honda's amazing 4cyl etc... but they will never slingshot a 8000 pound baja truck over 1000 miles of desert for a win.....

How does the amount of pipe or sharpness of bends in between the turbo and throttle body affect things ?

We want back pressure numbers . How about an 88mm turbo ?

I recently bought a Chevelle with a built 383 stroker but have no specs or information about the motor and power it makes. I want to boost it but don't know how to test the compression to be able to safely add boost. Any suggestions?

At what point in an LS Build do you raise the injection pounds from the factory ones

How bout tubo headers vs stock manifolds? What are the benefits if any from each other

You have to admit, the short runner intake and the big cam in that 6.0 makes a really flat torque curve. I'm not exactly into flat torque curves, but statistically, it's impressive. With a +- 10% spread, that 6.0 is flat from 3700 to 7200. -- On that application, the stock truck intake is nice because it's all one piece. No chance at a vacuum leak. -- The FAST is impressive. The fabricated intake doesn't hit 550hp until 6300 RPM. The FAST was there from 5500, and kept beating it until 7000. The LSXRt is super flat from an operating range perspective. +- ~6% from 4000 to 6300. Within 10% of peak power from 5200 to rev limiter. That intake, that cam, on a tall-deck stroker motor with a similar cylinder head would be killer from 6500 and down.

I still want to see Compressed Air Supercharging. Do a big bang

Have you done anything with the 8100

all of them

NASCAR 358 engines make 700 plus with the holley four barrel fuel injection system

Have you done a 5.3 or 6.0 LS and Maggie 2300 test?

Longer runners in the intake make more power earlier,while short runners make more power later?

If I have to choose my own cam, I'm screwed!

👐 HANDS Holdener!

So what is the point of buying a more expensive cam or a custom cam?

What if you supercharge a turbo charger?

Me: literally pausing the video to answer the question @3 min mark.. my answer? All of them! Hopefully I got the answer right, About to find out! Lmao 😂 Edit: yes!!!! 🎉 watch way to many of these videos

How do I donate to your patreon account Richard I need some of those old sbc parts for my 86 trans am those cheap eBay heads would be great

Is there going to be a second part to the ss2 vs the world under boost?

Hey Richard! I have an idea for a video. I really love the new trend of dressing the LS motors up like a traditional small block. But my question is this. How much power does that cost you to look cool like that? Could you do some A/B testing on a few different combinations? Test something like a 6.0 or a 5.3, with a typical warm street cam, and test different intake configurations. Start with a standard factory manifold. Then try a dual plane with a throttle body style injection set up, and try the exact same manifold, and do the fuel rails and either the conversions to put a stock style throttle body in place of the carb, or the 4bbl throttle body that is air only. Is there a cost to look cool!?!? I wanna see!

Personally I blame squirrels

The cam that makes the most HP with the lowest boost at the desired rpm ceiling. That's the cam you want

Well you know what we want 1000ft-lbs from 1000rpm to 7000rpm. Pull like a freight train or an electric motor. :-)

How is your cam line coming?

But EVERYbody says the kegger for the Dodge Magnum is JUNK. Can't make big power. Let's see!! #MoparMagnum5.9 #BoostToTheMoon

Just ship me a ls turbo exhaust manifold 😂 🤣 😂 🤣

But...any cam is a turbo cam

The question is: What is the CHEAPEST 1000 HORSE POWER engine combo ??? If you have the skills to build your own blow through carb I'm thinking it might be a Gen 6 BBC with GT45's. It just might make it the cheapest.

Where’s sloppy vs the world part 2?
