$$$$$$$$$$$$$$$$ too. I think the aftetrmarket manifold is better suited if you are going to continually upgrade the engine. If you are just doing daily driver, the SS intake should suffice.
True but who has over 1k $$$to just drop on a intake? Rather use the tbss and put that 1k towards a better turbo which would make much more than another 40 hp like that overpriced fast does.
There’s a simple reason why it makes more power , look how much taller the intake is, it give the intake longer and wider runners ..normally longer hurts the top end ,and shorter is used for top end power, but they figured out a way to get more top end and low end at the same time…I’ve never seen a comparison between having only wider runners just long and short, it would be cool to see a comparison when the only change is to the diameter of the runners ,as it will allow more air to flow up to a point until it starts to slow down…
But $350 for tbss vs $1200 for the fast... On a 5.3 it's more like a 10-20hp diff tbss vs fast I've heard anyway.. The 8707 has 226/238 duration .600 lift. I have the flex fuel injectors and walbro 255. Was dynod at 400whp and 400wtq.. I agree the $1200 for the fast could be put towards a turbo cam and turbo manifold with crossover.
It is sharp. But for a truck being used as a truck. Plus adding the price point. To me, you just can't beat the TBSS and if you start leaning towards more hot rod than truck, say a turbo or Is super charger. The TBSS 799 and only a 90mm can do 1000hp no problem. And on the street Having more torque and horsepower up to 4800. Means y the time the hi dollar starts to shine, the Scrimmage is over. But look wise, 🤤
I was going to do the tbss but i picked up a fast LSXrt with throttle body new in the box for $800 and almost knocked my wife over heading for the car. My question for you is i really want to use my factory fuel connection for now. Do you know the kit you got with the rails and the stock style connector? Info hard to come by on these. Great info new subscriber ✌️
For a budget build you won’t beat the TBSS intake. It’s a very good piece. The Fast offers some HP up top in exchange for some Hp down low. Same rules apply for boost but the Hp difference would be greater.
I would do a torque converter, a cam and springs, and a good tune. That’ll be a little more than $1500 (doing the labor yourself) but that will be your biggest bang for the buck there.
The link I put in the description is literally his LSXRT dyno video. Definitely recommend you watch it. He’s also tested both intakes back to back has said multiple times the graphs basically overlay each other.
The TBSS Intake is the Exact Same intake as the intake on the 2007-2013 Silverado, That's why I'll NEVER Spend $1000.00 for an Intake for My 2008 Z71!!!! @Costal Racecraft
The TBSS is definitely king in the OEM cathedral world. The FAST is targeted towards a performance application where you’ll see more benefit due to other supporting mods already in place like a good cam and exhaust. I would not recommend this be your first mod on a relatively stock vehicle. It’s two totally different segments.
It's not Stock, I've put Dual Exhaust a Truck Norris Cam and Lifters, Cold Air Intake, TB spacer, New Injectors for my Flex Fuel, new Coils and I rebuilt the 373 in the rear, I just Can't See Spending That Much for just 15 to 25 more hp.@@CoastalRacecraft
You can mess with the ports some but since it’s glued together from the factory you would really have to cut it apart and glue it back together if you wanted to modify the whole thing. It’s a great intake and makes great power but It’s not worth trying to cut apart.
@@CoastalRacecraft That's what I figured. I have long term plans of going boosted. Are there any other good forced induction intakes that aren't $1000+ ? Or will the tbss suffice in that application as well?
@@CoastalRacecraft it's actually in a Volvo 240 lol. With a ford 8.8 3.73 and spooled diff. And a RS5R30A Nissan built trans. (Similar ratio to t56 at less then half the cost and weight) It's a street/weekend drag car. Has the summit 8707 226/238 .600 lift 113 lsa cam so already makes power up top. And has pac 1219 springs, brt pushrods and trunion kit and headers with 3" SS catless. I have hptuners and have been able to make small adjustments. But po had it set on open loop as they dyno tuned it only then sold it. So needs a refined tune.
Ps it's only an lm7 but has l59 flex fuel injectors, a walbro 255 and Vette regulated filter as tbss is return less which isn't really ideal for forced correct?
I'd rather run the tbss intake that fast only gained around 30-40 HP compared to the tbss intake. call it 40 hp over the tbss intake at over 1000$. Nope not for me too rich for my blood. For that kinda money it needs to be at least a 100hp gain over the tbss intake.. Which wouldn't happen. Fast are great but stupid idiotic overpriced.
I have the lm7 summit 8707 brt pushrods and trunion and pac 1219 springs. Built 706 heads. It has the tbss and snake eater 92mm tb price vs power I agree. Tbss is suffice unless your squeezing .1 off your 1/4
The LSXRT manifold makes more power everywhere in the rpm range compared to the TBSS do the increased runner length over the LSXR manifold.

Sweet I subbed thanks keep good ls stuff coming please 🙏
Appreciate the support! Got some cool stuff in the works!

For sure. Cubic inch and head flow will definitely play rolls on that. On a smaller motor Like this I don’t see there being much Hp variance.
tbss makes more power than both all the way to 4500 rpm .. need to get mine swapped out ASAP
Correct the TBSS is more of a low rpm intake by design which hurts upper rpm performance. The Fast being opposite of that.
But $350 for tbss vs $1200 for the fast... On a 5.3 it's more like a 10-20hp diff tbss vs fast I've heard anyway..

It’s definitely a mod dependent on engine combo and goals.
I was going to do the tbss but i picked up a fast LSXrt with throttle body new in the box for $800 and almost knocked my wife over heading for the car. My question for you is i really want to use my factory fuel connection for now. Do you know the kit you got with the rails and the stock style connector? Info hard to come by on these. Great info new subscriber ✌️
Thanks man! I’m running a Little different set up so I ended up making my own fuel line kit
do you have before and after dyno graph numbers? would love to see the difference on your setup.
I don’t have one of my setup but I linked a dyno comparison Richard Holdener did. Great info!
whats the link to that specific richard holdner video??
Basically, the tbss intake is more for low end and Fast Intake is for upper/boost setup?
For a budget build you won’t beat the TBSS intake. It’s a very good piece. The Fast offers some HP up top in exchange for some Hp down low. Same rules apply for boost but the Hp difference would be greater.
Does your new LSXRT intake idle well?
Hey Jamie! It does! Check out our newest video for an idle clip.
Buddy could you tell me what is that hole on the side of the tbss intake? The one by the back of the throttle body on the side.
Yes sir that’s for a PCV system
I have a ss silverado 6.0 stock any recommendations? I have about 1500 bucks to start putting in stuff , thank you
I would do a torque converter, a cam and springs, and a good tune. That’ll be a little more than $1500 (doing the labor yourself) but that will be your biggest bang for the buck there.
He’s right, but also you should get this LSX,RT forget about any other intake manifold
Get you a Cam Motion little little chopper
Darn, I want to see dyno numbers.
Check out the link I put in the description. Richard has all the dyno numbers in that link.
richard tested the LSXr not the LSXRT
The link I put in the description is literally his LSXRT dyno video. Definitely recommend you watch it. He’s also tested both intakes back to back has said multiple times the graphs basically overlay each other.
They make the same power he did both they where in 1-2 numbers of each other
Richard tested them both and they make the exact same power. I don't wipe my butt without watching one of Richards videos, true story 🤷♂️
I was told the LSXRT has a bung or port for nitrous. Is that true?
Yes sir it just needs drilled and tapped.
@@CoastalRacecraft good deal, thank you. Is there anyway possible you could tell me the location of said bung?
You’ll see a round blank spot right next to the fuel injector. Drill and tap right there and you’re good to go!
Thats the wrong graph. Thats the lsxr graph not the lsxrT graph.
Both the LSXRT and LSXR have near identical performance numbers. You could run them back to back and they overlay each other.

Can you port the tbss?
You can mess with the ports some but since it’s glued together from the factory you would really have to cut it apart and glue it back together if you wanted to modify the whole thing. It’s a great intake and makes great power but It’s not worth trying to cut apart.

The TBSS is a great stock intake. Intake choice really depends on where you want your power. Is it a street truck or do you care more about track ET?

I think it is by far the ugliest intake ever made but im damn sure getting one 👍
Can’t go wrong with either one!
