RE: F.A.S.T. intake manifold
Man, you havent been on for awile... Jeese whats up?
Right now they are re-designing it because it picked up 20 RWHP on a stock car with a 93 octane tune. The tune makes about 15+ RWHP by itself.

ahh yes, the bi-weekly F.A.I.L. intake manifold thread.
it will never come out, ever.
or if it does, its gonna need a blower attached to it.

I emailed Brenspeed to ask if they were going to sell them with tunes to go with them. They said yes, but without new cams and new heads, you could only make about 5 extra HP.
So, spend your several thousand dollars on a supercharger instead.

RE: F.A.S.T. intake manifold
Here's a little bit of info that is on the C&L site about their new manifold:
"Given the flow rate of the stock intake manifold, it does not appear to be a restriction on your typical stock or mildly modified application where the cylinder heads have not been modified. This is not to say that a higher flowing intake manifold "CAN NOT" improve performance over stock, but rather to confirm that the factory intake does not represent a measurable restriction on the stock factory cylinder heads. Because of this, we are not willing to "go out on a limb" and make ANY potential power gain predictions based solely on airflow. This testing shows that the primary user for an upgraded intake manifold on this engine will be using either ported cylinder heads, a form of supercharging, or both. These are the people who will benefit most from an aftermarket intake upgrade. People with completely stock engines MIGHT find some improvement, and we will be happy to provide exact details when they are available, but our initial testing has indicated that any aftermarket intake for this engine will only be ideal for more heavily modified applications."
This means it's basically the same deal as the F.A.S.T. manifold. If you don't have new heads or at least some head work, an SC, etc etc....you're not going to see any gains. Apparently the stock manifold is not bad at all. I would like to have one of these things though....but for the money you need to spend to see any real power, you can just supercharge it and be done with it.
