Some guys on this board (me included), have 100-150K invested into their cars. Not that we're wealthy by ANY stretch of the imagination (actually its usually the opposite), but if you take this sport seriously, and dont look at it in the perspective of trying togain 100rwhp for 40 bucks, then 3000-4000 is MORE than acceptable. Especially when it comes down to winning or loosing.
I think with a few design changes, (ie..double edged flange around the perimiter, with removeable adhesive, SS Nuts/bolt, and 2-3 plenum braces, like the FAST and stock intakes run, possible burst panel provisions, and nitrous port provisions this would be a solid performer, and my company woulld be willing to purchase "In Bulk" IMMEDIATLY for the Corvette community.
But without some sort of physical restraint between the top and bottom, this manifold will crash and burn. This is PRECISELY why GM instatuted their plenum supports. They were getting too much plenum vibration under "stock" applications.
Provided we were able to see some real world mule testing on high hp NA, med-high boost F/I, and nitrous applications of course..
If you make these changes, we (meaning Total Performance) will contract with LME, to build 3 specific longblock LS7 motors, utilizing TSP LS7 heads, w/forged internals, and run them on a 3rd party engine dyno at QMP machining in Los Angeles, CA.
I will commit right now to this project, and fund all 3 motors AND testing, if you build the manifolds to those specs. Of course, I think before ANY modifications were made, there should be a meeting of the minds of the LS Based F/I tuners, on this application. IF the tuners can bring all of their ideas together, we might just have a winner here.
Although the F-body market will most likey not go for this type of manifold due to its cost, with the exception of the hardcore guys, Our company could sell these as fast as we could get them delivered to my Corvette community. If you need C5/C6 measurements,let me know. This can include cowl'd hoods if necessary.
I am NOT in any way bullshitting you. This is a product that is LONG overdue, and i am willing to put my companies resources into the project, provided this is a "Real Deal" application, with the ability to produce not only a manifold, but results...
PM me if necessary.

Thanks for the comments all.
This was never meant to compete with the high volume plastic intakes, and the reason the LS7 was first was primarily due to the target market (ie. Corvettes).
I am just showing my pet project that I am passionate about. Dont want to have to defend, but CF is not cheap. This is not a ricer CF hood that is made from fiberglass and then wrapped with 1 layer of CF to make it a "CF hood"; this is 7 layers moulded in steel moulds for high accuracy.
As everyone knows, you need to match intake-heads-cam. The intake was not designed for a stock LS7 and I will be totally honest with any numbers I show. Unfortunately, I have only had the opportunity to test on a stock LS7. Hopefully in about 6weeks I can access a cam-only LS7.

I wont sell a billet IR manifold.. They are nothing but heatsinks, that cause your IAT's to exceed 130-140*+. Although they sure are good looking, they SUCK in the performance catagory. I know, I've got first hand experience in that...
A carbon IR intake would eliminate that issue..

I couldnt understand your question, but I assume you meant, How do I know how hot the IAT's inside the ports were...
We tapped the rear of the manifold with an IAT sensor. This way we got the most accurate temps. In city driving at night when the ambient temps were around 70*F, we were seeing in excess of 140*. At 100+mph, it came down to the low low 130's. I think the lowest we ever saw it was 128*.

Some design shots:
Looking through the C6 Z06 hood (skin hidden) w/ top of intake taken off:
Cross-section down middle of C6 Z06 showing firewall (tight fit) and hood clearances:
Mockup on engine (custom CNC fuel rails):

Thanks all for your comments. Will let you know how it goes as soon as I test it on a modded engine.
The LS3 variant should be done in about 3-4weeks also.

By the way how is KB doing with the LS7 blower kits? Have you seen MTI's TVS blower for the Z06 that they just introduced?

I know you guys are giving him **** about the price but you should see the cost of "hard tooling" . A simple mold will set you back $15-20K . What you've made is awesome , I just think you need to spend more time developing your manifold design to achieve more power . I'll be doing something similar when my time arrives . I recently finished training on a brand new Hurco and I'm pretty excited .

The fact that you made 8 horsepower over the LS7 stock intake that appears to be nicely matched to the LS7 heads and cam is encouraging.
Hopefully your new intake will be better positioned to take advantage of the greater airflow requirements imposed by a bigger cam and/or head porting.
