LOD Speed works Manifold ...
Looks interesting for sure.
Since no text was included, I’m going to do my part and be too lazy to google... but what is the purpose of the 2 piece design here? Is it really for easy cleaning?

It's made out of three pieces because it is 100% machined, not cast. You start with a chunk of aluminum and run a bunch of spinning tools into it. Ha Ha.
Nice machine work though. Generous plenum size, but I'm not a fan of that short of a runner for a "street/track" car. maybe a drag car with a 1500 RPM range, that's about it.

Just looking at the inside, and outside, I don't see a lot of draft angles, so it probably isn't a sand cast piece. I'd hate to know what the tooling cost for that if it is in fact investment cast.
Speedworks says double digit hp and torque gains on an LS3 over the factory intake on their website. They also said it fits under a factory Camaro hood without modification, I'm guessing they mean 5th Gen Camaro. Would be nice to see a dyno graph with the intake vs an LS3 intake and a LSXR.
looks like good, classic plenum design to me. the plenum tapers off at the end and gets smaller, as well as looking like it extends past the last two ports. you'll notice a lot of log style and sheet metal intakes do this, and i'm fairly sure it's to try to ensure all runners get fed equally. stock manifolds don't do this, and purportedly run into issues with the last two runners running leaner than the rest.

77hp from just that intake on an already H/C LS3? No other mods, just additional NA tuning? Im skeptical of those numbers to say the least. Looks like my Performance Design LS7 carbon fiber intake is going up for sale. Only 50 more hp and thats on fully built max effort NA set ups(typical). Its a twin tb cross ram design with big runners.

25-40hp would be more realistic.

I will let you know how it does on a bolt on LS3 and then Cam only. Doing some fitting this weekend to stuff it on my C6 and trying to go after the NA stock cam stock head record on the 6th if weather cooperates.

BTW - I think you meant the last two can run rich.
If the last two runners get less air flow, given the same amount of fuel - the last two cylinders would run richer not leaner.
Running too rich can cause temps to rise. Overly rich conditions will cause heat because of excess cylinder pressure due to the extra fuel that is either not burning or partially burning.

As for the intake, it has always looked like a nice product. But they were on some forums maybe 2 years ago advertising....did it ever become available ? Has anyone ever actually used one ?
