Ported Intake Question
Help me understand....why does the FAST intake require firewall modification? If Chris can port the intake without it taking up more space, basically using the stock intake and modifying it, why can't the FAST guys do that? Is the intake very different? Why would they put out an intake that is such a PITA to deal with?
Just wondering...

Indeed, the FAST was not meant for the C6. The FAST drops in place of the LS1 or LS6 and accepts those fuel rails. The LS2 was a whole other animal as far as the intakes go. It's really a PAIN to swap a FAST in place of the LS2 intake due to the firewall and the fact that almost everything that goes on the intake must be adapted- fuel rails, injector o- rings, and MAP sensor. Only the TB fits and it isn't in exactly the same location as stock.
For 90% of the guys doing mods it may not be worth it. Not to mention the fact that the dealership service dept. pops the hood and sees whats up instantly. Even a painted FAST with the name ground off looks suspect.
But the FAST does deliver the most gain once ported - hands down.

Also, what is your process, turn around, and price? PM me if you wish.

Ported manifolds are able to achieve about 1/2 of what the FAST can. That's why I say that a ported stock manifold is great for about 90% of the guys who mod their cars. The other 10% need ("need" is such subjective word!) the gains that the FAST can give and are willing to pay that much higher premium for it.
Budget is a consideration in all modification plans. Some horsepower is cheaper to obtain. However, when you're trying to scratch out every last bit... it gets expensive hence the FAST pricing and things like electric waterpumps. The cost per hp gained is very prohibitive.

The answer is "D" all of the above.
The Plenum is different
The runners are different
and it's a different design geared not toward making a decent flowing intake that meets the manufacturer criteria, but rather a design that does as much as possible in place of the LS6 intake manifold.

Craig, as you know I'm very happy with my intake that Cory ported. I never thought the Fast was worth it cost wise, it's very expensive and unless you're going for 450+ hp no need to fool with it.
Here's my track results and intake install notes. It's an easy job.

Check the link above in my post - Cory (CHarris85Vette) has a good system set up. He ships you one, you swap it out, and you send him your original back. Worked like clockwork for me and the swap is really easy, with the couple of tips I posted
