Definately in once they figure out what all is included.

So it was measured againt the LS1 manifold not the LS6?

I believe it was only measured against the Weiand which I thought wasn't a real improvement over the LS6. I think I will wait till there is a comparison against an actual LS6/LSX.

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

Yes, the fuel rails are included. We even have a special fitting that the stock fuel line will connect to. For those with the earlier LS1 engines with a built-in regulator in the fuel rails and a return line, we will be offering an inexpensive kit that includes a regulator and return connection. Unfortunately this is not into production yet but should be in about 60 days.

What years are the earlier models? Would my 99 TA be an earlier model?

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.

jimdavis@professional

I am not sure I follow what you are saying. The alternative for an aluminum manifold is the Weiand at least $150 more plus the equivalent fuel rail kit set up is probably another $150. 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.

jimdavis@professional

The 1997 and 1998 LS1's used the return system and regulator. Since this change may not have occurred exactly with the model year, to make sure, look at your fuel rail setup. There is a crossover tube in the center of the engine that goes from one fuel rail to the other. If there is a small round metal canister attached to this crossover tube on the driver's side of the fuel rail assembly, then that is the "early" style setup.

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.

I think the question being asked is how does your intake compare to the other available options, not just aluminium.

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.

The crate engine that we used for dyno testing is an LS6 engine so we have one of those manifolds. In the very early stages of developing this manifold we did test it against the LS6 and we were a little better. But we subsequently made a lot of changes in our design and improved it. 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.

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.

technical

coil covers... fuel rail covers probably.

Correct, like the vettes. They clip onto the fuel rails, so if you use a different fuel rail, they won't just clip on.

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.

jimdavis@professional

The photo shown is of an earlier version of the design. The production models do have nitrous bosses on them.

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.

jimdavis@professional

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

Nick williams bolts up to a fast intake... if that's of any help.
