Richard Holdner has proven over and over again. The long runner fast will kill everything under every condition including boost, it beats everything everywhere under 7k.
Excellent data. Thanks for the effort and objectivity. Have you ever tested an OEM LS3 intake versus the Fast? Westech has but interested in seeing any other data out there. Thanks again!
You should also throw on a Victor Jr or other carburetor style manifold with a 4150 pattern throttle body. Give some info/love to the people wanting to keep the classic carbureted look.
I think the "carburetor look" is what EFI guys give when someone starts talking about jet sizes. Sorta like a blank stare mixed with a bit of confusion.
The BTR equalizer 3 would have been a good comparison to the FAST intake in this particular test. The trinity runners are shorter in comparison to the equalizer.
@@mr.c5217 that’s what that one was built for.. designed specifically for boost… had a few guys who ran one with boosted, said it held 37-38 lbs with no issues
@@tptrsn Agreed, There is alot of knowledge out there, but this channel is chalking up to being a massive resource of that knowledge. I built my own engine based off these videos combined with Richard Holdners testing. Hence my LQ4 has TFS225 heads and a Fast LSXRT intake.
Most LS guys are looking for more independent test on the stock LS3 vs ported rodmod vs the non-high rise Performance Design XS on close to stock LS3 displacement 6.2. Seems some people are not finding the same real-world results or numbers.
There was only 1 test of the PD XS vs Rodmod and it made 12 hp over the rod mod on the cammed ls3 on a chevy ss but the owner of the car removed it due to the PD XS having an incurable vacuum issue.
What the chance i can get a build sheet from you or have you make a build sheet for me? Airboat motor. 700hp high torque. Wanna go ls but needs to be light and beefy. Currently running 496 bbc and wanna get away from the carburetor an wanna go ls.
I like this 6.0 you built and the hp range. Could work off that but running 3500-4000 rpm constantly running and getting up to 58-6000 when getting across dry ground
The L92 intake is less likely to lean out at high rpm, and has an almost identical power curve...... And it's about $200 cheaper. It can give some fitment issues on some cars though.
It would be great to see this with a couple of budget intakes thrown in so all of us commoners (lol) could see if our budget intake was worth it :)
It wasn't better off keeping stock ls3

I would love to see Hi Ram vs CID 4.0
CID destroys it. The modified hi ram kinda closes the power gap but still the CID walks up top pretty good
Good to see you got your shoes on in this video.
Lmao 😂
when i overlay more than 2 i turn off torque to just highlight the hp curves might look less busy im not sure if your software lets you
quick question which throttle body was used???
Good information thanks for sharing

Gwatney tested it look it up vs heap of other intakes
Love this

I would like to see the BTR Truck Norris cam vs. the Texas Speed Torquer V4 cam. I think both are higher average numbers focused.
Great channel growing well done 🇦🇺👍

Need to see the tsp titan on that graph
From what i remember the BTR intake was made for FORCED INDUCTION
Same with the carbon intake..not really meant for na
@@abelthomas2406 I wouldn't use a Carbon intake for Forced Induction.

Great video
I would love to see 2 efi motor a ford 363 and a LS 6.0 with a street hyd high lift cam and a hi rise manifold shoot out
I wish you could fit the high ram without cutting the cowl. I would have no problem cutting the hood, but the cowl is a little different
Last time i came this early i became a dad😂
It wasnt yours, someone always comes earlier.
Which would be best in a boosted application ?
Just about anything man in boosted application manifold dosent do much
I have a Fast LSXR intake on my C6 LS3, and that engine is responsive.
No Rod mod or ported LS3 intake?
Is there an inter cooler that works with the PTR?
What about edelbrock pro flo xt?
Fast lsxr did really well down low would the stock ls3 still be the same as the fast hear ? or has this out performed it being a stroker ?
Curious about these with boost. Currently trying to finish up my twin turbo C6 Z06 and actually took off a fast 102 for a ported trinity
Hey guys, appreciate the info ! What cam would you recommend with the Fast LSXR intake, for a '06 5.3 V8? Thanks.
U know Richard Holdner tested ever intake imaginable #wrongcam
He did, but it's great to see the testing results confirmed like this!

The more the better..
Can you do a like 4 short runners and 4 long runners? Or mix in some mid runners?

@@granddya5323 thanks yeah I think I talked to him on his channel
@@granddya5323this was done by NRG no?
@@sixohslow3417 Rubin Mercado. He has a video testing a direct swap from his rod mod.
Hey, I have a 6.0 out of a 2500HD. Which way should I go for a mean street car?
can’t WAIT to throw this in my vette 😼
Any chance of testing stock and rod modded for additional comparison?

Cynlinder head test next ?
That a gretta sticker on the dyno room window?😂
They straight up copied Steve Morris. Pretty sad
@@aslackersad? You know the saying "imitation is the best form of flattery?
do you guys usally run 12.0 air fuel
what about compared to a ported stock intake manifold
im running a 6.7L ls3 n/a with a ported ls3 intake manifold so that's why I'm curious
shouldve tested the texas speed sr3
Hard to beat the Hi Ram. Especially in a drag race application.
If you could only test a cid intake
Where's the MSD? or did I miss him explaining that....
MSD does not make an LS3 intake manifold. Only LS1, LS7 and Gen V LT
@@JacobVillemain, my bad... I have the LS7, I just assumed. Thanks!!!!
All it needed was ITBs to be added to the test
i would like to have seen the the power average taken from peak torque to peak horsepower.
Did you watch the video??
ill stick with the ls3 intake ,no one has proved a better manifold to 6500.
The L92 intake is less likely to lean out at high rpm, and has an almost identical power curve...... And it's about $200 cheaper. It can give some fitment issues on some cars though.
