LS THROTTLE BODY UPGRADE-WHAT'S IT WORTH? HOW MUCH POWER IS A THROTTLE BODY UPGRADE WORTH ON AN LS?

[@ufarkingicehole]

Richard.. you are KZbin gold brotherman!! You have saved so many people countless money and time with your no BS approach and wealth of knowledge.

[@simonhardgrave4568]

Sir Richard is my go to for not buying pointless shit

[@orangetruckman]

I’m still in disbelief that Richard doesn’t have over a million subscribers ☹️

[@Russell_and_Rosko]

I like the new "What's it worth" format. I've got one. 20 degrees of cam duration. Whats it worth? 196 to 216? 206 to 226? Stock vs supporting mods? Love the videos Richard 🇺🇲

[@ChurchAutoTest]

Great test Rich. On my PDSC LS I didn't start to see gains over the stock 87mm throttle body until I was over 700 whp (800 crank?). Considering that 87mm has about 25% more flow than a 78mm, the 650 hp plateau in your PDSC 78mm example makes sense. Great note on the blow through setups too. I've made over 500 whp on a 62mm throttle on a blow through setup on my Honda without any issues, and one of my employees is making nearly 800 whp on a 70mm tb blow through setup.

[@richardholdener1727]

we used a 65mm on the Bonneville Honda but there was no need...it was free

[@joaoescudo1561]

In a nutshell: Upgrade your throttle body (and everything before it) to match your intake manifold.

[@wildnfree223]

The comment I was looking for

[@MrDamhandiman]

I can't describe how you and your work have brought my brother's together

[@strokermaverick]

Great upload, Richard! The big 3, already have the throttle bodies optimized for stock engines. Throttle body companies have always advertised gains, for stock engines. Especially, in the fox body days.

[@hydrocarbon82]

One point with supercharger gains - a roots/screw blower is simply a multiplier for inlet air pressure, so ANY restriction is literally multiplied. 1/2psi lost between the throttle body and blower will drop peak boost from 14 to 13psi. Those tend to be the only time people really can see gains, since few ever build 700+ hp NA engines.

[@Kstang09]

Aww yeah, workin' the shop, cue up the Holdener 👌

[@richardholdener1727]

Right on!

[@Prestiged_peck]

Cant wait to see you do one of these videos on a EFI 300 ford Id do 1.7 rockers, a mechanical fan delete, a smog pump delete, and then of course a custom upper intake.

[@richardholdener1727]

me too

[@BOOT]

Herd if you run enough boost(LOTS) on a single Large TB, the blade will get stuck open. Can't rem the company that came out with a dual TB intake for boats, due to that issue. Something to do with blade diameter, surface area and leverage.

[@RallyElite]

the savior of street automotive youtube has posted!

[@LSturboguy]

I went 105mm TB as mine is big Turbo ls 427 low ram and I also went up to 2400cc injectors. worked Good on mine, never really bothered with a stock 1 mines got big flowing req ported heads I agree they are a must on a boosted big cube LS

[@DR-px5sh]

I had no idea that the inside of a truck manifold looked like that. Cool pic.

[@Sleeperdude]

Great information thanks for sharing

[@bowhite1293]

I wonder when I'll ever lay my hands on a stock 78mm TB. Maybe one day.

[@SubePelayo928]

Am I the only one that was counting the intake runners on the Thumbnail motor? v12 LS?

[@richardholdener1727]

first one that noticed

[@dsm4959]

Great content as always.. Of course a PD Supercharger will see more gains from a Throttle Body upgrade compared to turbos or a centrifugal Blower. Just wanted to ask, Have you ever done comparison test with Turbos or centrifugal Blower and Larger Throttle Body? Happy Thanksgiving... Go Lions!

[@richardholdener1727]

yes-it did nothing at the power level we ran it at

[@crushthequarter6863]

Thanks for the data. I was wondering about this.

[@a89proof]

I've had a running theory for some time now that selling bigger throttle bodies to people that don't need them produces a perceived result in that the engine is effectively at wide open throttle at an earlier point in the travel of the throttle plate, due to the net area equivalent now happening at say 60% WOT instead of at 85%. How this correlates to electronic fuel and spark control as mapped against throttle position sensor values with no additional tuning I suppose would depend on how air flow calcs are made? I know I've driven plenty of cars with stock throttle bodies and meager outputs where under high load scenarios, there would be no appreciable difference between ~75% throttle and wide open, foot to the floor - and I can't imagine why you'd want to make that resolution even worse.

[@LS_Rooster]

Class is in session

[@kennybryan4816]

I have a 2014 chevy reaper truck with 6.2 and it has a magnison supercharger. It's equipped with the stock TB . I've been. Thinking about upgrading it to the 95 mm TB or would you recommend going to the 102 mm ? . If I do will I need to get a tune for the air fuel setting ? Thanks Richard I've learned a ton watching your videos!

[@richardholdener1727]

bigger will help-your tune should add fuel with higher boost

[@ztwntyn8]

One that needs the most flow. Too expensive for just cam headers IMO. Head now yeah. Flow

[@chrisbenedict2245]

Do you have a video on electric water pumps vs belt drive?

[@MADDMERK]

Richard post video ,i put my learning cap on 🤓📝😎

[@3dracing]

Good info thanks

[@ztwntyn8]

I guess if you don’t need you don’t have as much throttle control per idk travel of the pedal or percentage open and around %80 I doubt you have anymore input in your butt if you don’t need it. Rather have just enough for control if that makes sense.

[@nickcook7408]

common plenums ad runners are for losers, you want an individual throttle per cylinder. more even cylinder filling and better response. ITBs are always the answer.

[@francisbeaudry8598]

[@randallservidio5919]

Thank you

[@AndreS_-df2nw]

How did the dual stock style TB on top of the Hi-ram as in the thumbnail perform?

[@richardholdener1727]

works fine-if you look close-note that is a 12 cylinder LS

[@benwhittaker8630]

You've just shown the people why Gale Banks is "wrong". I love his work but you can tell when he's trying to pull the wool over your eyes, like with his Cummins intake elbows. He never quotes power gains specifically, but repeatedly highlights the flow bench results and concludes that based on the evidence, it WILL make more power and use less fuel. However real world testing shows no gain.

[@ztwntyn8]

Hmm, I think Gale has his stuff together. He is mainly looking at air density and improving that definitely makes more power (more air density)

[@fastec5]

Diesels and Gas motors behave different to different things. Banks is the 🐐

[@jasondoyle355]

Shit comment. Gale Banks DEFINITELY knows what he is talking about and sells honest quality products. Post less in the future

[@benwhittaker8630]

Yes, Gale Banks does know what he's talking about and makes good products, but you've all missed the point I was making. With the example I gave specifically, cummins intake elbows, countless people have done back to back testing, even at four digit power levels, and seen no gains. It's just like putting a larger throttle body on a stock truck motor, all that extra flow of one component adds nothing to the system as a whole. Banks intake elbow flows huge amounts more than a stock elbow, but the stock elbow flows more than the rest of the system, so it's irrelevant. If you go and look at the videos they've made on it, they always harp on about the increased cfm it flows, and then push the idea that increased airflow means more power, but they don't seem to directly say that bolting their intake horn will give you more power (because they probably know it doesn't).

[@thecaptn311]

Was just wondering if the intake swap is worth it on the ls2 cammed 5.3 I shoved into a blazer

[@richardholdener1727]

A Fast is the best choice but expensive

[@thecaptn311]

@@richardholdener1727 Thats fine wine for my beer budget mostly gm part# swap. The tbss intake is looking like my budget winner. 5.3 dish pistons 862 heads cut .040 ls2 cam and 26918 comp springs. basic copy of your ls2 cam swap dyno build.

[@falfighter]

im guessing its significant on a forced induction motor

[@simonhardgrave4568]

Supercharged maybe turbo nope because your force feeding not pulling air through. I'm sure Richard will chime in

[@falfighter]

@@simonhardgrave4568 but still have to pass air thru the throttle body. i dont think it matters if you push the air or pull the air

[@richardholdener1727]

the draw vs blow through matters a great deal

[@zslemp]

can we get some l92 testing please

[@richardholdener1727]

I have L92 vids up

[@erickbernard8208]

Does an early ls( 3 hole ) fit an M90?

[@richardholdener1727]

no

Join Richards live feed a bums!!!!😂

[@samemerzidis3810]

About time you let us know the cost of some things but we need also the engine parts costs for upgrades including labour hrs costs

[@richardholdener1727]

shop rates vary from $0 to $100+ per hour, so no way to know.

[@orangetruckman]

Cost for parts can vary by your location and definitely labor rates. Parts cost is not what this channel is about. The knowledge that Richard shares is far more valuable than the time needed to lookup part pricing!
