New BTR CAST INTAKE

I made 1049whp with this intake. SBE 5.3, billet s476, 24.5psi, TR6060, BTR Stage 2 cam. It peaked at 7200-7300, fell off rather quickly but then flatlined to 7500. I can post the dyno graph a little later. On the street, I pulled it to 7800 and it never felt like it dropped off.
Here is a 1194 wheel dyno pull on a T4 billet S476 at about the same boost at less than 7K RPM with a smaller cam and a stock gen 3 truck intake through an auto trans.
See why comparison data matters?

Never said it didn't. Just offered what I had.

Ordered mine about a month ago and now it's looking like at least another month. I can't wait for this thing!
Car currently has a bad vacuum leak and isn't too happy. I suspect I've got a cracked FAST 92, but haven't taken it off yet to confirm. Honestly, don't really want to know until I get the BTR Equalizer in my hands. All the boost!

Anybody have more results on this? Engine Masters did an episode on Blower Manifolds S4E46 where they tested different runner lengths that concluded the difference between them wasn't so great under boost.
Previous episode on Intercooler vs Water/Meth injection S4E45 was eye opening that it showed a big difference is cooling between cylinders when using water/meth into LS6 style intakes. Basically the rear cylinders got the most of it and the front ones didn't get much at all. Wonder how a short runner ram intake like the BTR does on cylinder distribution of fluid injection like water/meth or plate nitrous/fuel.

Here are some overlays that I said I'd post a few months ago. Lol
Smoothing is as low as it goes. Trying to show as plain/real numbers as possible. Remember the hi ram was also paired with a converter that was tighter. This is as close of a comparison as I can provide.
1000 hp pull on both graphs is the same pull with the BTR intake
The first sheet has a hi ram overlay on the same boost level (both seem to have maxed out the turbo as in both cases more boost made negligible power gains)
The second being the closest peak power made with the hi ram vs btr to show the curve differences. The pull with the hi ram was 22 psi vs 25 with the BTR manifold.

That makes no sense, as at the low end you'd expect the HiRam to shine far above the BTR. So on the top graph the green trace looks odd below 5.5k. Unless there is some reason for not operating below 5.5k ?
And TBH...I'd expect the HiRam to shine over the BTR above 5.5k too.
The lower graph may make sense if the lighter coloured trace is the HiRam

You sure are hard to please. Both times I've posted clear descriptions you have to question it.
I don't understand what was so difficult about the way it was explained
There is one line on each graph that is the same pull. That's the BTR intake. BLUE
GREEN is the hi ram on the same boost level
LIGHT BLUE is the hi ram on 3psi less boost FOR A CURVE COMPARISON

Which does seem expected. It's a pity as a lot of work did go into it
It just seems that it would take an exceptional combination...and very high rpm's for any short runner intake to really shine on an LS.
If anything, the 6-7" or so of the HiRam or maybe ProFlo or whatever the exact number is, is around the sweet spot for a normal high rpm motor, and the 10"+ of the factory types the sweet spot for everything under 7k.

Here were our results with the BTR Equalizer 3 intake on a n/a application. To be fair, the cam on this car (BTR LS3 Stage 4) peaks at around 6800rpm, so it wasnt the best setup for the E3 intake. However we were curious how it would do against a ported LS3 intake on your average cammed street car.
Our first test on this car with the ported LS3 inatek and 102mm tb,
