7700-RPM JUNKYARD 5.3L LS INTAKE TEST. HI RAM VS LOW RAM-WHICH HOLLEY LS INTAKE MAKES THE MOST HP? 

I absolutely love that you're willing to try "stupid"(read as unconventional) things on the dyno like removing the lid of the intake.

The most gangster move pulling that lid off at the start of the run , you a real one 💯

Keep up the good work always love watching your videos I’m always learning from you and I’ve very thankful for that. Happy holidays to u and yours

That lid off was one of the best things I’ve seen 😆

Once again class has been very interesting thank you very much teacher and I shall continue To stay close attentive.😀

That's why the active intake in the Dodge 392 switches to short runners above 4000rpm.

In my '57 Chevy, I have what started out as a Chevy Performance crate LS3, and added a Texas Speed Stage 3 NA cam, the Holley Hi-Ram, and 1-3/4" long tube headers. Together with 4.11 gears and a Circle D 4,200 stall converter, it runs great on the street, especially when I stand on the gas. :)

nice vidéo rick tanks so mutch merci beaucoup

Always playing with the cathedral port motors...while us LS3 guys wanna know how this would work on our rec ports!! LoL!!! Great video!!!

Great tech video

I just bought a 2003 Cateye with a 5.3 in it and having no previous engine knowledge besides routine maintenance, i can't thank you enough for your videos! Goal is to make her a pretty quick race truck, but i'm starting out slow and working my way up. subscribed!

I love this monster!!!!

AWSOME video

If your toy is a Pantera or Mangusta, you can play around with tall intake manifolds, GMC style blowers, etc. The engine is behind the driver so a "tall" engine is not an aerodynamic or aesthetic concern.

The low ram is very similar to the stock manifolds on my Buick V6s, not idea for stock to medium cams but decent for the bigger cams. I have a cam set aside for a later project that is 262/262 deg, 303/303 advertised, but even then it's still a bit on the short side for the ideal runner length. But otherwise it's very well designed with a good area for the runners to support pretty wild builds, tapered runner as well. The major difference to this Holley though is the plenum on mine are a sideways oval log-ish plenum which allowed the top side of the tapper to extend all the way to the top of the plenum, while the bottom side is rather short like the Holley low ram. I can't recall exactly on the length of the runner, but the middle (average length) from back of valve to the opening in the plenum is 245mm. Mine is actually called in the community the high ram, there is a even lower ram version used in the previous gen LN3.

Hey Richard are you ever going to revisit the l28et? Maybe dyno and test upgrades. The Datsun guys would really appreciate it 😂

Crazy 🤣 Sorry I missed some mission about no lid or throttle body.😮

That no lid test was wild :D

Would be interesting to see a comparison with the "sandwich" style intercoolers (tick performance etc.)

Where’s the lid off chart? That’s a very interesting component to this comparison- as the air doesn’t like to turn. I’ll bet it had some remarkable results!

Hard to beat the better versions of the stock manifolds and they fir any vehicle

I love the way the high ram and even the low ram look, I love the way the sheet metal intakes look… but I am loyal to the FAST because it has gobs more of torque and power over them. Gobs more.

You Should Do Another HighRam Test ... But Use The One That Has The Water Methanol Injection System On It ... Show How Much Difference Adding That To A N/A Engine Makes ...

I’d be interested to see what the stock intake does in comparison to these on the hp and torque curve down low, as well as sheet metal intakes vs cast

The high ram is good performing but fitment is usually an issue

those intakes are like the single planes of the LS world.

Now that you did the no lid test, I want a holdener powered variable length intake runner test. Pull the lid, slap in place runner extensions and then pull those as revs pass 5500 or 6k.

Hey Richard great videos man, was wondering if you had any info on an amount of boost that is safe with no ring gap on a gen 3 6.0

Love your vids Richard! Do you have an email or platform I can ask questions about LS stuff please? Thank you!

Who needs shop towels to wipe you hands, when you have your pants 😊

I'm thinking the tall ram will produce peak torque lower in the RPM range.

Love ot

from this test the ultra low ram from holley would be even more loss in the mid range. that hi ram is hard to fit either cut a hole buy a hood lower the motor lower the k member lol but another note how would the trickflow split intake and elbow do?

Compare the same combo with the FAST LSXR!!! Waaaaa🎉

Great video!! Could you do a test on the new one 105mm tb vs 92 tb or 102mm tb?

Hey Richard. Thanks for your content. Can you help on which Holley Hi/Rise is right for my application. I have a sbf 302 bored out to a 347 stroker.

Low ram vs. Truck manifold please.

What did the pull look like without the top part?

U should test the Holley ultra low ram Richard when ever u get a chance I would really like to Know what the ultra low ram puts out

When you took the lid off, it made me wonder about 8 stack systems vs hi ram single throttle. Seems to me if both were same overall length, hi ram wins because of lack of turbulence caused by the internal t valve. Ever test this comparison? 8 stack wins the cool factor hands down though!

Will the High Ram fit under the hood of a 86 C10

Explain the electrical storm going on , on the valve cover.

Chrysler know that in early 60s with long ram Wedge motors

would have been nice to include the stock intake graph

Do you have a go to kit for afm 5.3 delete? Do you have a throttle preference wire or cable? Pros and cons for each? Do you have a website with a list of parts tested and combination hp?

Could you do a test where you run the m90 on the low ram?

No such as Stupid or unconventional.That would say NDT/DT testing serves minimal gain ; As an engineer you should understand, theirs just the untested! 🍻

Cut some valve reliefs, and more cam duration please!!!!!!!!!

Have you tested the Holley single plane intake with the Holley 4150 throttle body yet?

I know you are testing the ram style manifolds but how do they compare to the midrise holley manifold.

Richard can you build a efi sbf 363 stroker motor with I mild cam hyd roller and put it on the dyno

We need a ultra high ram that sticks out the hood.

How does a turbo change this....or does it? Will the long runners still make more through the power band with a turbo?

Any idea of the wet flow characteristics of the ultra low ram intake? My vette makes 680hp has meth injection with a stock ls1 intake so I need a better intake for my setup.

is it the same on boosted V8 engines? is the longrunner is better overall than the shortrunner manifolds?

Would you expect better or the same results on 6.0 ls2 with the comp 459 cam and TEA 799 cnc port heads?

Would moving the throttle body further from the intake on the low ram, increase plenum volume enough to gain any losses back?

Richard what do you think about the Texas Speed SR3 Titan?

I see SBE 4.8s and 5.3s turning 7k+rpm alot these days. Even boosted. My question is: can a gen 4 SBE 6.0 run 7k+ turbo'd with a stage 3 cam? No upgraded rod bolts needed?

Now do a vid with turbos por favor

Richard! In any world, does boost change power curves?

PLEASE DO A MID RISE PLEASE!!??

Whats a good low profile intake for the LM4/L33, under 6500rpm, street/drag race? I have an LS swap I'm working on where hood clearance is really tight. I was thinking maybe ls3 with adaports but I'm not as familar with whats available for the LS.

Can you do some l77 stuff

Great job...unfortunately for me my swap dictated the ultra low ram. I have a stroked and built L33 with a summit stage 4 and related upgrades. Didn't port the heads but I plan to eventually run my 80mm vsr turbo. Compression is a little over 9.5 to 1. Plan on running roughly 10lbs, maybe less..possibly a tad more. Electronic boost controller will give me 15 to 16lb overboost with button. Engines gapped for 15+, everything forged

No gusher from the low ram set up

Now compare that to a stock 5.3 graph to show that when, looks like it still makes good tq under 5k probably thanks to the compression

Max effort na 5.3 I want to leave the block untouched but not SBE methanol and carb what pistons and rods and cam to make a lot of hp

Why didn’t you run the Holley mid ram in this test as well ?

Runner Length on the hi ram is 6.50 inch.Is that correct? thanks

I'd like to see a comparison of a high ram vs a low ram with intercooler on a turbo setup... see if the charge cooling makes up for it

Hi Richard I have a question the crankshaft turns twice as fast as camshaft So at 7700 RPMs you were talking about the camshaft speed In reality the crankshafts turn in 15,400

Dyno Shorts! You could probably start a new fad. I mean people are wearing brand new jeans with holes in them.

What about the ultra low?

Lid off. Flipping the ignition off at high rpm You have Huevos 😅

Did i miss the graphs for no lid?

Now add boost and do it again please.

Will the high ram fit a 5.7 hemi?

Why no lidless short ram pull? Surely would have been worth at least 1.6 hp up top 😂

Why do companies like FAST name short runners intake as "Race" specific knowing that long runners are better performing throughout the curve 🤔

2:53 Something is pouring out of the top of the engine!

Holley also makes a mid ram.

SBE?

M90 on low ram???

Where's the throttle body cam?

Notice oil pressure drops off after 7k

But what happens when boosted

Send me the low ram, I have $200 here for ya
