I actually sold my PORTED FAST and switched to a stock LS2 intake when I went FI and I make great numbers

Really a LS6 mainifold and even the LS1 and a LS2 on a FI set-up works very good! When you are FI a lot of factors that help Naturally Asperated motors don't do the same thing for Forced Induction - it kinda goes out the window, so to speak
I have 701 RWHP and 582 RWTQ on my LS6 manifold!
Thanks,Matt

From my with experience FAST intakes on my Procharged set up is that they flow very well. I've never had an issue of them breaking under hard boost or sealing issues. Most problems with FAST intakes is improper installation.

Its just an alternative way to make power. In most cases, you can accomplish solid power, with minimal mods, on a boosted application. But that doesnt stop people from adding heads, headers, valvetrain, cat back exhaust, etc etc etc..
Is a FAST intake and larger TB a MUST?? Nope..Is it just another way to add more power? Yup.
Think of it this way.. Any way you can make more power, and limit the amount of boost, is a good idea. From a pure mechanical functionality standpoint, it is significantly safer to make all the power you can with the motor, then top it off with the power adder.
But at the end of the day, you can make the exact same power by turning up the wick.
The FAST leaking issues come from improper (Inadequate torquing) torquing, which causes leaks. They DO come slightly tweaked from the factory, and do require a tad more torque to seal them. When a person goes by the GM guidelines, they will tend to leak.

Many people have issues with the FAST being that it is a 3 piece design and being Forced Inducted - They tend to leak!
Really a LS6 mainifold and even the LS1 and a LS2 on a FI set-up works very good! When you are FI a lot of factors that help Naturally Asperated motors don't do the same thing for Forced Induction - it kinda goes out the window, so to speak
I have 701 RWHP and 582 RWTQ on my LS6 manifold!
Thanks,Matt

I sold my 90-90 setup when I went to FI. They may make the numbers, but they are POS's as far as quality goes. Definitely not worth $1,200 on most FI setups. The money is better spent elsewhere. I'm not even sure i would run one on an FI build with no budget.
