What intake now? For boost
https://www.jegs.com/i/Holley/510/822032/10002/-1 sniper hi-ram sheet metal intake
For a street car a lot of people get caught up on low end tq. Whats funny is most of the same guys that complain also dont have decent tires. I actually try to reduce low end tq on full send to try and help traction. While it sounds lame less low end tq and more traction beats blowing your tires off at 2k rpm like all the LSA cars.
Ive used most all the intakes, sniper, hi-ram, pro-flo, vic jr, super vic, fast, stock, etc. With the intakes that reduce low end tq I’ve never thought man I wish I had more tq. I just control boost and timing to suite my needs and sail past the low end tq blower cars.
That said even the so called shitty chinese holley sniper has easily ran 8’s so none of them are really hurting your street car performance all that much.

No. On an all-motor car you will be raped on the street with no down low torque. You with boost is a whole different ball game. HP sells and torque wins races. My old torqueless Hi-Ram setup would get murdered on the street. Going up in CR, bigger cam, and increasing plenum volume will be helping immensely. As for traction you have to find a way to plant it.
Low rpm torque may not show up in ET’s, but I have to wonder about the fun factor in heavy cars around town stop light to stop light. Low compression 5.3’s with low rpm torque killing intakes in a heavy car aren’t going to have great response at low rpm. That’s why I still believe in cubic inches for a street toy even if it’s not popular here.
This entirely supposes you have the octane for it. Not everyone can/will run race gas or E85.
However, in recent days Holley have come up with these. They look cool, but no doubt will be utterly ***** with their very short runners. But they are cast, they look like far better quality than the fabbed stuff....and I kinda like them. Even the bellmouth shape around the runners in the plenum look very nice. If only they'd make something similar, with longer runners and say 8-9" max height ( And no...the horrible mid-ram design doesnt count, even if it doesnt perform as bad as it looks like it should )

10 LS Engine Myths That Refuse to Die
Verdad Gallardo How much tq do people need? Most people don't have enough tire on their daily to use more torque. I have a 5.3 in my daily and can still obliterate 345's at pretty much any reasonable speed. Granted most people drive overweight buckets, but boost quickly more then makes up for cubic inches. Plus being on E85 I really like the 5.3's fuel mileage!
I dont think I’ll end up not having enough tq. I had to put a electronic boost controller because when I’d attempt to pass a car, at about 45mph it came it to boost just easing on it and broke the tires loose, got sideways and almost put me into oncoming traffic.
I went 5.3 because I’d like to get better fuel mileage. Look how the 5.0 runs, that’s an even smaller engine. I’m doing a bigger stall while I’m at it and SERIOUSLY thinking about stepping down on camshaft. I look at all these small engine, heavy new cars and how they run. If I play it smart and plan out my combo correctly, it’ll be fast, quiet, get decent fuel mileage and drive like stock until I put my foot down. Only think that will hinder this is my stall, but I can faniggle the timing to gain some response back. And lock it up early under light throttle.

Hell I could still easily and quickly get to 100mph without even going over 3000rpm, and never seeing any boost. I've driven thousands of miles and never been above say 2500rpm lol. For daily use....it simply doesnt need any more than that to make very brisk progress.
Of course yes, when pushing harder doing very illegal things, traction is an issue. But then that's not really "daily" use as I see it. If I did that every day...I'd have no license.
That's where you absolutely do notice the torque. I've had various engines in mine, and types of boost, and also n/a. Of course they're all good, and all different...and sometimes similar.
But say going from a 403 back to a 383, or even 383 back to 346 which I've done literally back to back with same supporting install.....it is very noticeable the lack of torque the smaller motors have low down. Now a 5.3 is still no small motor, but I really cant think I'd ever want to fit one to a car I used often when there are so easily bigger options available.
I'm currently on 382...but really, next time around, I'll probably end up getting back nearer the 400ci range, although that may more likely go to 416, as I fancy the idea of one of the 4" CCW cranks.

Although as to how the above pans out with intakes....we never see dyno reports in the 1-3000rpm range, where lets face it most daily stuff would be operating...and at part throttle.
So they're probably a non issue. I know that despite poor results in the intake test, the Chinese Holley i have on mine, going back to back from the BBK SSI....feels no different on the road at all. If anything it actually seemed to spool a little earlier..
But the fact it is cheap crap does irritate me, and the noise it makes also irritates me. Just havent decided what to replace it with, but those new LoRam's look interesting. Although the big front end on them, doubt I'd have enough room for one.

Of course they have enough tyre ? How much tyre do you need on a daily run in the car ? where you are not trying to go fast, where you are not revving the crap out of it, etc etc ? At none of those times is traction a concern ( unless you live in the snow ), and you would pretty much never be in boost.

Trust me I get having a larger engine if you drive some over weight, under geared, vehicle like a truck. But most people here try to optimize a setup and not drive such poor performing vehicles. Personally having had all manner of larger LS's before going to a 5.3 they just didn't impress me very much. So I keep going back to 5.3's in different chassis and they have all performed much better then the larger engines they replaced. I have never felt a need to have more low end torque and I've had arguably some of the lowest torque setups available (big cam, short runner, low compression, big turbo 5.3). But everyone has different views on what is sufficient and why they make all manner of engines. To each their own, build whatever tickles your pickle!

If possible, my LS7 can run pump until 12.3:1.
It would depend, I am not well versed in non-LS7’s.
Your compression must of been pretty good or non-LS7 heads. I know I posted in the forced induction section, they way made it sound is that all setups do not need any down low torque.
I think the other reason behind this new intake if the popularity of the hi-ram intercoolers, and now have a chance of getting under some hoods with this new shorty version. With guys revving stock 5.3's out to 7500-8000+ RPM now, runner height shouldn't be as much concern.
Well I had an LSX454, shitty IRS, and a short runner intake... I still had too much low end tq for 275 radials. Never went back to all motor though, don't want to be that slow ever again. lol Keep in mind you posted in the Forced Induction section...

It is nice, and exactly why I have a street car and not a drag car. I have two other states within minutes of my house and head out all the time to explore open roads. We have a ton of relatively wide open roads that I've never seen police on, some even had semi organized racing going on for years. That said I've gotten a few warnings but police here are pretty cool, much better then living in the city.
I had LSX-LS7 heads, 11:1 compression nothing fancy. I just don't get the fascination with low end torque, I'm never in the low end long enough for it to matter. Plus once your moving you never go back to low end you just down shift. Maybe people drive really lazy and lug 6th gear around? I really don't know.
