The FAST is a great manifold and it makes some gains especially with throttle response. However that price tag is a bit steep...$800 man. Add in their TB and you're looking at over $1,000. Every now and then you can find a used FAST for around $600. Another option is to get a ported IM with a V-Max ported TB like I have. I went with Bare Essentials Racing. They tested their intake manifold against the FAST manifold some time ago. And their manifold held up pretty well. I think it was about only a few hp less than FAST. And the price makes it a better deal. I paid $250 shipped for their manifold after sending in a core. The core costed me $175. So all in all I paid $425 for the ported manifold. Factor in me selling my original for $200 and it comes out to $225 total that I paid for it. Some companies are selling them cheaper, like $150. But I went with BER because they were the only ones who offered dyno results from their comparo with FAST.
And I did the same thing with V-Max. I bought a core TB, sent that in plus $150 for a ported one, then installed the ported one and sold my original. I do it like that to avoid down-time. But you can't go wrong with a ported manifold if you went that route over the FAST stuff. Check out some of the companies offering ported stuff. You can save a lot of money and get comparable performance.
