New BTR CAST INTAKE
Question of the year, take a hi-ram chop a few inches out of the runners and take 1/2 of the plenum away and see how it does. I think the answer will come down to if you can fit a hi-ram, run a hi-ram, if you can't then look into something that sacrifices the least power. However, we don't have any comparisons so we don't know what that sacrifice is.
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!

I have a dyno comparison. Months apart though so, weather may have played a small part in the numbers.
The ONLY other factor is that a looser converter was installed before running the BTR intake on the dyno. I can see that also playing a part in power lost, but not 147hp worth.
Same combo each time: SBE LQ9, s485, same camshaft, 317 heads, btr 660 springs, 25 psi boost both times.
Hi ram made 1147
BTR made 1000 on the nose (dyno sheet says 5.3, the two lower power pulls were with a 5.3, but the 1000 hp pull was the 6.0 overlaid
I know they aren't both scaled the same. I will try to get them both scaled in RPM or both in MPH if I can remember next time I go out in the frigid cold to look at the dyno computer. lol
FYI: The MPH scale will naturally look like it made more average power than RPM so without having a graph of both in the same scale you can't judge too much on "average" power.

The 2 lower RPM pulls on the BTR intake were with a 5.3, the highest power pull was his 6.0 overlaid. Probably using the overlay to show the curve differences in displacement for comparison.
Re read the disclaimer on the picture... the higher hp pull on the sheet labeled '5.3' is from the 6.0. That's just how it worked out when I overlaid the 6.0 pull on the 5.3 dyno session.
The car was switched to an aluminum 5.3 mid summer and I ran it on the dyno before and after to see what it would make since we hadn't ran it except at the track with the btr intake.That's the only reason there's a 5.3 mixed in there.

Like the guy on here selling super expensive custom fabbed intakes a year or two ago.
"So and so car went 8.50 with one on low boost with a 427".
That's great, except the stock truck intake has been almost a second faster on a 6.0.
We need COMPARISON data. Not apples to chipotle burritos data.

I'm not sure I follow which pull is which configuration... What intake was used on the 6.0?
The upper picture shows power and torque for hi-ram on 5.3?
The lower picture shows, from top to bottom:
Unspecified intake on 6.0
BTR on 5.3, twice.

Top graph is a hi ram on his 6.0
Bottom graph is BTR on 6.0. Two of the pulls were a 5.3 put on there for overlay purposes.

Its NOT that I think he would skew the results to make the BTR intake look better (I actually think Holdener is a pretty awesome dude that likes facts),
I think that he either wouldn't choose setups for a fair comparison, or would omit the results completely if they weren't favorable.
2 good examples:
1. The intake he wants to test the BTR intake against is a Victor Jr. When he tested the High Ram vs the Jr, the High Ram blew it away. Seems like testing vs the Vic Jr is just a fluffer test.
2. He sent me a dyno sheet from when he tested an LS3 intake on a cathedral setup using adapter plates. It made a lot less power than a TBSS intake, so he never published the results.

To be fair on BTR...even the graphs they posted before its release, were very disappointing, so their marketing seemed to change to it's mainly for high rpm users. I just wonder how high you need to go to reap benefits....
It's a cool idea, it has been executed well with the low profile, but ultimately the very short runners are still the issue.

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.
