Help me plz.
I have LS1 from Camaro and I am going to use it for drifting.

I bought
Ported Throttle Body & MAF
COMP CAM CAMARO XR275HR
COMP CAMS VALVE SPRINGS 26918
COMP CAMS HI-TECH PUSHROD 7.400 #7955-16

Will it work with weiand intake??? Or better to buy from LS6 or fast???

the weiand flows about the same as the LS6 and the ported fast flows better than all...if you go with the fast dont waste your time on the 78mm...get in touch with Vengeance or another sponser that sells the ported 92 or like size with TB. I run the Weiand now and I love mine but eventually will save up for the fast setup. I love how my Weiand looks though ( polished and shiny)

I want to save the money. I can buy weiand intake If I don't need FAST intake for my mods.
weiand intake cost about 300-400$ vs fast 800-900$ (+92mm throttle).

Yes, on a budget a Weiand or better yet a used Weiand is a good choice. You can even open the inlet w/ a dremmel. If you search will find a few threads where I have noted deatailed flow information as measured by MAP & MAF.

FYI:
-used Weinad can be had for $250-$300 ($200 if you are patient)
-used LS6 $300 is the going rate (maybe $275 on the right day @ the right moment). LS6 is much lighter than the aluminum Weiand.

BTW, Welcome to the Forum. I see that you are a new member from Russia.

Weight is important for me, becouse the engine will be swap into my Nissan Silvia S15. So I think to buy one from LS6. Do I need change something like injectors? Or I can put it bolt on to my LS1?

Thx for welcome. I like this forum!!!

PS: sorry for my english)))

what about BBK SSI?

AlbertDRIFT

What is it? Is it better than from LS6 or weiand intake?

it's supposed to be good for about 12-15 more hp than a Z06.

Stick with the LS6 Intake. The FAST is best only when you do serious heads like AFR or Trickflow. the other vendors are made of metal. You dont want that. LS6 and FAST are made of strong polymer plastic which is lighter and willnot have heat soak

Stick with the LS6. It makes as much power as the BBK or Weiand, with a fraction of the weight.

Yes, stick w/ the LS6 since weight is an issue & it is as good as the Weiand & BBK, as noted. You're gonna have to measure in order to get the correct push rod. You will also need a tune in order to get the benefit out of the cam, ported TB & intake.

If you were doing just the intake, the fuel trims in the PCM could handle the change without a tune. However, because you're also adding the cam & ported TB, a tune will be needed. You should look into a set of long tube headers, as well.

Absoluetly incorrect!! I ran it on my stock 6.0L LQ9. I gained 21rwhp(same day testing), with my stock exhaust manifolds, my .470" lift camshaft and all...Everything Ive seen gains with a FAST intake from stock to crazy...

He was talking about a 5.7L LS1. Obviously, the 6.0L has the advantage of moving a larger volume of air, which is why you experienced the gains. On the 6.0L, the MAP pressure drops due to the size of the LS6 runners & probably somewhat of the inlet size.

You would still see great gains even with a 5.7L, the 6.0L isnt magical. I could argue that his cam has .500 lift stock and more duration.

Like I said, Ive seen everything in stock form pick up with the FAST.

Now, you sound like a wanna be. There's nothing that you can tell me about the LS6 intake that I haven't already measured & recorded. Both, the LS6 & the FAST intakes are excellent products. There is defenitely an advantage in the 6.0L in that the volume of air, per unit of time, moving through the runners is greater throughout the RPM range regardless of your cam argument. He does not need to spend money on a FAST intake @ this time.

Recording the MAF & MAP through the RPM band yields the most accurate results. I can get him up to 440 g/s @ 100 kPa up through 6600 RPM using an LS6 intake w/ the proper intake mods. Only after that point will he need to go to a FAST. Once the runner flow increases to the point where the MAP drops below 100 kPA @ higher RPM (even after a mild runner port) will he need the FAST. That can happen somewhere between 410-440 g/s depending on inlet &/or runner mods.

Look guys, this guy is drifting this car. He isn't trying to break any power records or set the 1/4 mile on fire. The LS6 intake will more than do the job for him.

I gained 24whp and 49wtq going from the weiand to the fast 90 on stock 853 heads. If you can afford it do the fast and do it once.
