Paragon's dyno test shows the Halltech Hornet's adding 14hp for $800, and for $2,500($1,700 more) you can get up to 18hp with the latest Eventuri C/F Intake.
Guess at $425 per HP extra for the Eventuri I'll stick with the Halltech, even though the Eventuri's got a nicer design.
The intake comparison dyno video showed single runs from stock versus each intake with variances between 5hp and 12hp.
Now anyone who has dynod this car also knows the bone stock car will show variance of up to 20hp from run to run when you DO control for intake temps. It can ve much higher when you don't control for them.
In other words there is absolutely nothing in that data that would be able to make me choose one intake over another.
I haven't seen this testing completed yet but the proper way to test an intake is on the road where the vehicle will properly show the effects of air moving over the vehicle from zero mile per hour to 130 mph or wherever you stop your test.
A dyno environment will not be able to accomplish this.
You do it on the road doing controlled condition data logging with high accuracy acceleration testing.
I personally went with the Halltech , the manufacturer's reputation and talk about fuel trims being closest to stock is what sealed the deal for me.
Honestly I'm ok with the $$->performance with the stock street stingray setup below 5k RPM; up top is where I think it needs that extra edge so hence the Halltech.
The eventuri intake looks really nice. They did a nice job with make it appealing aside from functional. Time will tell how well it performs on the street and track. You'll hear all kinds of opinions on here but in the end, the decision is yours. Just make sure you are happy.
Look at Paragon's intake shootout video (bottom line results posted above^^^). Halltech returned +7whp, so roughly half of what is claimed. You are not going to see big gains from an intake so manage expectations going in.

Paragon's claiming 14hp on the Halltech's top end:

That said, the price is...hefty.
True that about the Eventuri, although I'd be willing to bet my 2023 C8 that had they ended the left & right air intakes (stacked)above & below one another, instead of side by side going into the Throttle Body, the airflow would've been a bit better via less restriction since a 90 degree bend in any/all airflow is the equivelant to 10' of straight pipe.
Take it from a guy that started in his Family's HVAC company back in 1987 while I was 15, to the highest licensed Commercial/Residential General Contractor since 2003(Not boasting, just reassuring).
Seeing that most in America have been price gouging since 2009's The Obaminator as Prez, maybe I should consider releasing lightweight floormats for the C8 to eliminate approx a pound of weight via pre-cut C8 floormat shaped Home Depot Self-Adhesive Film, and charge $29.99 Shipped. ;-)
Better quarter mile times with better MPG via the weight savings."

seems like the drop-in filters would be the better investments from the information that’s out there.

This. I remember a number of years ago Hot Rod Magazine took a built Mustang to various dynos over several days and compared results. Big variations from one dyno to the next; big variations on the same dyno from one time to the next.
I saw gains from going from a no-rise cast iron manifold to a Medium Rise Aluminum AirGap RPM on my big block 70, but these little claims to HP are nonsense. I’ve been down this road with 5 liter mustangs… this nonsense is a waste of time and money. If Chevy couldn’t get 500hp, you probably won’t.

Chevy easily could if they wanted to; they didn't want to.
Pretty good price on the AWE track dry intake right now. I was going to go Halltech but this price makes it tough. Stinks it’s two weeks out or more tho. Best price I’ve seen on the Awe shipped for less then $800 with tax.
Let's all send our cars to paragon for dyno results.
This is the way
Actually having them do a blind test without knowing if the cars were stock or what intake it had on it would be the way. The data you'd get would be entirely different and confuse most people seeing it because the error variance is what you'd be seeing instead of any consistent gains or losses.
I just wouldn’t bother. Save the money for real mods.
my last C6 made 908whp on 93 octane with SAE correction. This was before adding trickflow heads, a 2.7" pulley and a custom flex fuel setup. Having come from a car with "real mods", I don't have any interest in doing that again with this car.
like I said earlier on this post, you'll hear lots of opinions on here... incliding mine! If your goal is to make a bit more power without breaking the bank on power adders, pick one of these and be happy with your choice. Personally, this car looks fantastic and drives great, as-is. If I were choosing an intake, I'd go with the Eventuri because I think it looks amazing. At a car show, it would look phenomenal. This is because this is what's important to me. If performance per dollar is more important, you might want to look in the direction if a drop-in filter.
