Too much data showing otherwise. It is possible that a "certain" cam grind is just not matching the dynamics of that intake, that can happen with heads etc...
But to say that the LS6 is superior as well as the LS2 is just not true.
Components mismatch, yes, I agree with that, everyone knows that one of the most common errors is doing so and making less power.
Now is the FAST "LORD" of all intakes, no. But it makes the power needed with the right cam specs and heads, more than a LS6 or LS2 (in stock forms).
The LS2 is a good intake but it needs modifying, ie: porting. The Aussies have proven that and once ported the LS2 does outdo the FAST. The aussies even designed a costom tool to port the LS2. Now that is innovation.
Bottom line, we go back to the magic word "COMBO". properly matched with the right parts, the FAST has it place in the market. still too darn expensive though.

But go ahead and stop thinking. I am not making a claim the data is in the thread look at it for yourself. The Engine lost HP and TQ !!!!!!. not a small amount either. -

Iam talking about:
1- Full specs of setup (including cam specs)
2- Tuning specs (timing, AFR etc...)
How can any one agree with you if these info are not available and most of us do make more power with that intake?
read J-Rod's post, that is one of the posts that makes the most sense. something is definately not right (obviously) but where? That is the question, and is that intake really to blame?

I'd be there aren't but maybe 4-5 head/cam 347s on this site that could make more then 410 hp on a mustang 1750de at 1100 ft above sea level.

The Ls2 got a bad rap from A-B testing done early on a controlled engine dyno where it lost power. Folks ahve begun to port them and fix all the various issues witht hem to get them on par with say an LS6 intake.
Did you see the threads on gearchatter which addressed this?

I could see the ls2 intake needing some porting due to the modling flash in the plenum area but again cam specs will have an impact on how well any fo the manifold perform.

Cam specs are not something i will hand out freely.

That is why I refer to J-rods post, that the intake might not be to blame.
We have seen that cam specs also have different power potential with different heads, take AFR 205s, they prefer traditional splits over reverse or no splits for that matter. So someone running a set on a reverse might just come out and say, AFR205s are crap I only picked 10rwhp over my ported LS6s, get my drift
This is where we do not agree with your comments.

Well, I dont see why you are arguing with him about the FAST's. He is questioning TSP, Tony Mamo and Don Kinder and acting like they dont know what there doing???? They forgot more than this dude knows about lsx motors IMO. - We've know Slowhawk and TSP and there cars for years. Ive never heard of this guy or his shop.

Some stated that the intake (Fast) may not be the culprit, in Sean's tests, becaused he has cammed his set-up for LS2 LS6 Intake and possibly not the FAST! Does anyone have a properly cammed FAST set-up that's comparable to Seans set-up? CID, Heads, Comp, etc.. The only way to make these comparisons are to have everything else be as close to equal as possible, otherwise it's just talk! I think Seans onto something (as we all know cam timing is important) He needs to properly cam a FAST intake, and discuss the result! Just MY .02!

He talks about things he clearly does not understand, and tries to pass off his incompetence by saying that no one else knows what they are doing. I have yet to see him contribute anything useful to any discussion he's been in.
