Modified Intake Idea! Input welcome
I still think its a really sweet project and awesome craftsmanship. Outside the box thinking is where some of the greatest ideas were founded.
They understand that the internal runners are what change power and make the big difference in a manifold.
Ive done as much intake dyno testing as anyone, this intake would be a fun project and is surely scores points for being different. I dont think it will make much more power if its properly tested against an out of the box intake. He will gain a couple from going to the 90mm and maybe a few if he did a good job removing casting flash and minor porting!
- There isnt a runner difference between the LS1 & LS6 intake, its difference in plenum volume.
- The Weiand/Lingenfelter intake is a revised LS6 intake with a slightly larger plenum and small runner changes. Now this is information straight from Weiand (I have been speaking to them about this project)
- As the "runners" empty out what refills them with air??? The plenum, which is intern filled by??? The throttlebody.
So my entire thought process for this intake has been simple, get air into the intake faster, to get it to the larger cleaner runners faster, to get it into the cylinders faster, and get out of the motor faster. I have been an auto mechanic for 12+ years and have worked on multiple race teams from small dirt cars to large pavement cars. I dont mean to discount anyones thoughts or your dyno results here. But all motors perform differently with different parts. I have built 2 race motors at the same damn time, with all the same parts. 1 had just shy of 1000 hp the other sucked at life and we ended up tearing down.

I dont think its ignorant to buy, say a FAST 102mm, and here is why. Some people dont have fab skills or tools, and the FAST does exactly what your doing. It has a large throttle body opening, just like your trying to accomplish. It has the maximum plenum volume that will physically fit in a Camaro/Corvette, and there is no changing plenum volume on an intake, it is what it is. It also has the bonus of optimised runners as well.
I do think your project is fun and unique. I really like the finish on it as well, looks good in there. I wish my FAST wasnt gray to be honest.
Heres a couple of pics showing intake manifold velocities in the plenum and runner of an LS intake manifold, just for a visual.

When I can I will get numbers up here.

LOOK AT THE PRETTY COLORS!!!

Just trying to give a guy props.
Where did you get that wrinkle black paint? What brand?
I think that intake will do very well under pressure.
But it has alot of metal in the runners, so a skilled porter will be able to accomplish the "magic" in the runners paired with ported cylinder heads, should use up that new tb opening.

It's probably the VHT wrinkle stuff. I seen it the other day at Autozone.
The intake feels really good in the car, Im still having some tuning issues in regards to idle and need to get the car on the dyno as well.
