How do I know this?
Because it's the only one of the two that's available right now.

They will likely both excel in different areas and compliment different supporting modifications.
It seems as if the Weiand Street Warrior will yield more gains in the lower to mid RPM range while the FAST might show more in the mid to upper ranges but still provide an overall better package for most NA applications.

Might want to consider Performance products Typhoon aluminum intake.

I also saw it last year when it said: "estimated ship date 1/28/08"!

OK speculation based on an observation: Weiand has an LS1 intake manifold out now and it loses power over stock.
I fail to see why everytime a company announces a part to be rerleased (and they keep pushing the date for release back), people think it has to be the best yet available over existing, proven parts when there is no info available on it. It gets pushed back for release because it doenst work.
There is no evidence to suggest it would be better since they couldnt get the LS1 weiand to make any power.

There were some dyno charts from Mast Performance using a preproduction unit put up on LS1 Tech showing some promise but there was still nothing truly conclusive shown there.
The FAST 90/92 still appears to remain the clear choice for most (all?) applications in this particular ball game.

I am throughly enjoying my SPINmoddedFast. While I did not get the dyno gains some folks got in the midrange (14 hp, 16 tq all above 4500), you CANNOT argue with the consistent 2 mph in the 1/8 and my 4 mph gain in the 1/4. (my bolt on best below was a bit of a fluke as I'd leaned my car out too much, I repeat 11.4's @ 124 very consistently now).
I have a spreadsheet of all my runs so I track this very carefully and those gains are consistent, every run.
The FAST is a great mod and added nearly as much to my 1/4 mile MPH as my cam with ZERO downside.
Except for the noise it makes, I don't like it, the engine sounds kind of hollow and junky now in the cab IMHO but I live with it for the performance.

With the stock intake I really didn't hear the engine from the cab, now I do. The thick stock intake does a lot for NVH control.
I'm kind of a sound guy, I love my cutouts for that reason. Another example, one of the sweetest sounds from a car is on my 71 442 when I open the secondaries on my Quadrajet. The moan of a Quadrajet when opened up is music to my ears.
The sound of the FAST is not music. It allows the valve noise (I have a very high lift cam) to come into the cockpit as it seems to echo the valve noise. Valve noise isn't pretty noise to me. That said, sound is very subjective, I'm sure some folks love the sound of a FAST.

I have stopped believing in the Weiand Street Warrior for the LS2. I don't believe we will ever see anyting beyond the prototype. However, if by chance we do, I will be more than surprised if it can match the proven performance of the modified and ported FAST (SpinFAST) for the LS2.

Doesn't bother me though but I don't have a high lift cam lol.
