Lot of money to spend on intake & TB to not upgrade the heads. At least send the stockers for a CNC porting or use LS3 heads that flow much better than any stock cathedral. I’ve also found there’s a considerable difference between full length long tubes and shorties, even if they are cheap eBay long tubes.
The MOST Important bit of info for this entire build was unfortunately held until the end of the video...and that is ENGINE SOURCE &/OR OWNERSHIP/RUNNING STATUS (ie. Existing owned running re-fresh, Rebuild purchased Junkyard Core, Existing/Owned Blown Engine Rebuild etc.). While this is an awesome guide for someone who wants to spice up a running LQ4 and doesn't mind spending a bit of cash for guaranteed results without pulling an engine, you could see how more guys than not would take that FAST Intake money and buy a Stroker or similar Forged Rotating Assembly for a 4.8/5.3L Aluminum Block etc. You get what I mean. Great video nonetheless. I would however change the title to "Running LQ4 Refresh/Upgrade". Keep up the good work. I like your style.
@@DannyR2681 I know that, this manifold, 102mm TB and otr was one of my first mods with exhaust and tune on my grange. All up was good for 32whp. 305 at the wheels in an 1850kg car gets boring after about 5 years so I slowly upped everything else over the last 7 years. I was agreeing with someone else and telling what’s happened to the parts I had, and he is dead right, except when I got my fast manifold it was $600 and now they’re over $2k. My custom manifold I run was $1250, so if you’re planning to go anyfurther and are worried about cost, forget the fast altogether as on its own is worth basically no gain unless you add another $5k worth of stuff
@@baddaddy8718 it all depends on your set up and what you’re using the car for she I’m using my set up and car for Drifting so I benefit from the higher revs of the fast intake, compared to a stock OEM car intake.
I'm running the same cam but BTR trinity intake,the Fast stuff is proven but dam expensive!!!$750 -800 13:49 is my limit on an intake. Looks like a good build and love the part numbers always help.good luck with it
Those are really nice parts and that’s gonna be a really nice ending with a Lotta good easy horsepower gains you realistically should be at the 500 range not for 450
He prob spend close to 6 -8 grand tbh. U don’t need to spend that much to gain as much hp as he will but this will definitely make it easier for tuning and reliability.
Hi Ken, I have done this recipe on a 2003 Sierra lq4 with drive by cable and it worked great! So yes it should. But to be safe always ask Summit or the place you order from to confirm compatibility for each part. That way they are responsible if there is a mess up and would have to make it right. Sh#t happens right. So always cover your base.
Very nice. I have an LS1 camaro i am trying to add some power to. Its a headache. This recipe would just about eat all of my budget and i dont think it would get me quite to my power goals. Id really like to get 500 to the wheels and call it a day. Starting to think that might be impossible on my budget. I do really like that intake tho
Prc 5.3 heads,tsp magic stick camshaft fast intake nick williams throttle body stock fuel rails 65 lbs an hour injectors to be safe 505-520 wheel hp 91 octane more with e85
@@nowayjose596 yeah I've spent a couple years trying to figure it out before committing money. Looks like I'm going to be going with a procharger. Turbo may make a little more power but bigger headache, bigger cost, and I'm running a mostly stock tranny.
@nowayjose596 I suggest you stop talking. You seem very ignorant. It's already been dyno proven with multiple combos of what it takes to get an ls1 to that power without boost. It's very easy to do
If you want 500 hp, add a cheap turbo, springs, injectors, fuel pump. Don’t change the cam intake or throttlebody. 8 pound spring on the gate will get 550
Hi David, the stock LQ9 has 345hp at the crank. With this cam, intake, injectors and a good tune, it should add 100hp or more. So it should be around 445hp or more at the crank. Of course, rear wheel hp is lower than crank hp. In my experience 15 to 20 percent less than crank hp at the wheels on a 2 wheel drive.
@ptbelttactics you can make more boost with the fast manifold than you can with the truck manifold. And the fast manifold looks better and fits better in more vehicles because it's not as tall
But do you guys know the difference between cathedral port and rectangle port? This is a cathedral port set-up where the FAST is very much beneficial. So your point may be true, but has literally nothing to do with this video.
@@baby-sharkgto4902 fast may be the top dog, but is big $$$. If it beat everything by 30+ average BHP and TQ it would be worth it. It does not gain that much over other choices. Buying a different manifold and a set of long tubes with the leftover cash would be a better option.
Hi Shawn The Gen 2 LT1 is a great engine! I think they had 300hp stock from factory. They had their flaws but those can be taken care of. There is a great article on how to build an LT1 on www.onallcylinders.com Titled * The Last Small Block*
The FAST intake manifold isn't worth the money, the stock intake is THE best manifold as proven by anyone who knows LS's. Waste of time & money. A cam with headwork on standard intake/throttle body far better money spent.
No, Not $ well spent. No Hp gains just loss of $ and no significance other than looks. Playing and just talking , do your research and actually know what your talking about other than just your personal preference for pretty colored intakes. And summit? This ain’t 1997, these kids only know wat system tells them their sitting in front of, know wat your working on and with and BUILD SOME FKN “POWER”!!!!!
What heads are you using? I have a GEN4 LY6 390ci I just last week got done assembling, fully firged Callies crank, Compstar rods and Diamond pistons. BUT....my weakness if my old ass LS1 241 ported heads that onlly flow 304cfm@.650. Also, I still have an old ported LS6 intake and stock TB. My top end parts are probably costing me a good 100+ HP that I could add to this N/A set up. I'll be boosting it soon so I first want to squeeze as much N/A power out of it as possible......
