Yeah, I'm going to stick with the LS6 manifold I bought a few weeks ago because this wasn't ready then when I ordered it I'm going to wait to see how the LS2 design for LS1 cars works out against a FAST. If this manifold is even within 5hp or so of a FAST on a stock setup, I'll be ordering this setup. If its better than a FAST, even better then

I'm sure you could EASILY organize a group purchase for these bad boys.
Also, Jim, is the fuel rail in the pics also included?

Group purchase
I am sorry but we do not sell direct to consumers so we cannot do a group buy. The way our distribution is organized, we have to honor the relationship we have with our distributors. Possibly you could organize a group buy with the company that has been quoting prices on this board.

To use our manifold with the early setup, you would have to utilize our supplementary kit #52160 or you could plumb your own setup using any aftermarket EFI regulator. The stock regulator is an integral part of the stock fuel rail assembly and cannot be used independently.

A couple things that you may want to consider, is to set the intake up, either with an adapter plate or what have you so that aftermarket throttle bodies, like the nick williams 90mm TB can be used with the intake, alot of people that have already purchased those and fast 90mm intakes might want to try this, and if the TB will work with either intake, it will for sure make it alot more fisable for people to swap them with their fast intakes.
Also, bosses for directport nitrous would also be a very good idea, as it seems that there are more and more people taking that route these days, being able to do it on your intake would also be a good selling point.

So our package is about $300 less than an equivalent combination of parts from others and based on our tests, makes more power. Seems like a win-win to me. And if looks are your thing, our polished version is cosmetically far superior to a black plastic manifold.
Most popular is the GM LS6 intake with a ported stock TB. The next big hike in power comes from the FAST 90mm setup with a 90mm TB.
I'm definitely interested as I only have a LS1 intake on my 99. But I'll probably hold out and wait for results on your 96mm TB/intake. If it performs better than the GM LS6 intake for similar money it will fly off the shelf.

Dyno testing gets to be very expensive. We have invested a huge amount of money in development and tooling expenses for this manifold already. We paid $6,000 for the crate motor alone, bought just for this project. And that is just the tip of the iceberg.
One other thing I forgot to mention is that the stock coil covers will not work with our manifold. We are designing what I think are some very sharp looking polished aluminum coil covers. These will be out of extruded aluminum which can be relatively thin and light weight. Again, this is another product that is down the road a ways.

I never went back and tested it against the LS6. We never really considered testing against the FAST, mainly because of the huge difference in cost. The Weiand is reported to be slightly better than an LS6 manifold and we are somewhat better than the Weiand so we are making the assumption we are better than the LS6. Assumptions can get you in trouble however.

You should have gotten on here. Saved yourself some money and shipped out an intake or two to someone near you. Just two weeks ago me and about 9 other guys did dynos at the same time.
Switching a manifold doesn't take much. I don't see how testing all three (weind, LS6, yours) couldn't have been done in a day.

I am not familiar with the Nick Williams unit. If it is 90mm and our inlet is 85, a minor amount of grinding on our intake manifold inlet would allow it to bolt up, assuming the Nick Williams unit has the same three bolt pattern as the stock LS1.

Yes, you are correct. In hindsight, that would have been the thing to do.
