Speed Secrets: FAST LSXR 102mm Intake Test!

How much horsepower you can gain after swapping to an aftermarket intake manifold is not a one-size-fits-all situation. In this episode of Speed Secrets, you’ll learn why power gains from an intake can vary. Featuring the FAST LSXR 102MM intake and Comp Cams 54-454-11 and 54-469-11 Camshafts!

So basically, don't buy a Fast unless you're doing heads and cam??

How come you are not doing this test on the ever popular LS1? A 5.7 l? It would be great if you could do one on that test so we can see how much power the 5.7 makes with the nice Cam and a huge exhaust. Like a kooks setup. There are thousands of us who own 5.7 LS1s we would love to see this test on our engine

Would love to see the FAST 102 vs Sniper EFI Duel Plenum 102/92mm on a 408 stroker. Been looking at the Sniper intake lately but there is not much about it.

Hey! It's time for a new test with the BTR Trinity's @ 8000 rpm!!

[randallsavage]

since everyone is always concerned about peak horsepower, yes shorter runners should be used on the 6.0 in this test.

I would love to see the difference between victor Jr intake with fast efi 2.0 vs fast lsxr 102mm. Can you show us the hp difference between the two?

I have a 2002 5.3 I’m installing one and 34 inch headers, a 92 mm fast intake with the truck north cam I will be running the stock heads from the LM7 what else do you think I could do to get a little more low in torque

[MrCGrammer]

Question: what size injectors should I run with the LSXR102 intake and throttle body? They are going on a stock LS1 in a 99 Trans Am WS6, going to be boosted later

[slyr]

On LS1 whats a good intake MSD Automic or Fast LSXR

[raulreveles]

I have a 5.3 with headers and 100 shot of nitrous. What intake manifold and cam would you recommend?

[jesse_legacy]

Would you have to install fuel injectors? Or would you need them right away for full power?

[alexhicks]

Hey I have a 5.7 aluminum block. With fast 92mm Ported throttle body and intake manifold and camed up. Running E85 fuel. With that combo What Hp do you think I am putting out.

[alexandermcdole]

Is it worth putting on a full bolt on ls1 with a small cam?227/236 565.579 110 lsa.

[michaelmacgregor]

hey does anyone what type of plastic the fast lsxr outside case it made of

[blainebreak]

Sooo the upgraded manifold wouldn’t do much if you just had a cam and other bolt ons 🤔 or would it? I’m stuck between is it worth it or not.

[onewheelup]

im confused i just watched another video of yours where you test like 18 intakes and the fast didnt do squat compared to a stock ls3 intake and supposedly truck intakes make more torque and power.so if i have a ls3 style intake with a cam on my l96 6.0 buying a fast 102 intake or even a 10 tb dont do anything, right ? so do i just keep what i have ? i need more torque and power would be nice.

Richard I need some advice, basically I’m new to this and right now I have the time to do things I’ve wanted to I’ve begun collecting parts for my 5.3 vortec, but I’m trying to get my hands on a 6.0 motor itself to work on separately since my 5.3 is my daily and getting me around reliably, I bought a aftermarket ls3 throttle body 102mm, fast 102 intake, my problem is I’m not sure I got the best cam, I found one practical new for cheap on marketplace, it’s a Texas speed 212/218 .550/.550 112 LSA. Along w some springs and pushrods. What would be the best cam for either setup? I can sell this one and buy another if I need to.
