Professional Products Intake Manifold Yeah I know it'll weigh a bit more, but if it performs like a FAST, it's a nice trade-off for some pretty bling. Professional Products intake manifold includes fuel rails.
Anyway, any results with a 90mm TB?

I found a price of $365.95 for the LS1 (# 52061) on a non-sponsor website.
From their website. They have 3 different versions available. A LS1/LS6 85mm version, LS2/LS7 96mm and a 96mm specific LS1/LS6 version. They also sell TB's. Someone needs to invite them over here to post some dyno comparisons and notes.
"This manifold is a result of over one year of development with extensive dyno testing. While it is difficult to improve on the original G.M. design we were able to show increases all the way up the rpm range with significantly more power down in the low and mid rpm ranges than competitive aftermarket manifolds for this engine. And yet we still matched or exceeded them on the top end. The LS1 version has an 85mm inlet (see our matching 85mm throttle body or use stock throttle body) while the LS2 version sports a humongous 96mm inlet bore. Use your stock 91mm throttle body or our matching 96mm model. Both the LS1 and LS2 manifolds come complete with fuel rails and necessary plumbing with fittings to match factory fuel lines. If your LS1 is an early version with a fuel return line, you can utilize our 10670 or 10671 fuel pressure regulator with this setup. The late returnless systems utilize a regulator in the fuel tank with the fuel pump. See the regulator section of this catalog. Some Mix & Match Information… Our LS1 Manifold will accept up to an 85mm throttle body. Our LS2 Manifold will accept up to our 96mm throttle body and could conceivably be enlarged for a larger size if anyone makes one. If you have an LS1 engine but want to run a throttle body larger than 85mm, you can use our #52064/52065 LS2 manifold and one of our LS2 96mm throttle bodies or the stock 91mm throttle body. Both our LS1 and LS2 manifolds come with a set of fuel rails. The reason you need to use this special version of the LS2 manifold is that the LS2 injectors are shorter and are a different diameter where they go into the manifold than the LS1 and have a different electrical connection than the LS1 which means you cannot use the LS2 injectors on an LS1 manifold or with an LS1 harness. The #52064/#52065 version of the LS2 manifold is machined to accept LS1 injectors so you can continue to utilize your stock wiring harness and injector connectors but gain the large 96MM inlet opening."

For one thing, the moving air, combined with injected fuel would have a cooling affect, and as long as the car isn't just sitting idleing, I wouldn't think it'd be that big of a deal.
Ford didn't implement the same concept for no reason

Hmmm, looks interesting. The exterior looks like a FAST or LS2 intake, so who knows, it may be just as good.
****, for $365 that's not too expensive of a risk to try it out. I wonder what the return policy is on it? Go to a dyno, dyno the car, swap the intake, make a few more pulls, check the programming, and if it doesn't make more power return it for false advertising.

I think the $365 is for the satin finish. The polished one is probably more. Either one is half the price of a FAST 90, and will work with just about any TB you want. I can't see anybody getting the satin finish once you've seen the shiny one.
