GM High Tech - CAI Testing

I wasn't sure if anyone posted this yet.

The intakes involved in the test were ADM Street, Advanced Flow Engineering, Airaid, Cold Air Inductions, Fastlane, Late Model Racecraft, New Era Peformance

It was a pretty good read. They tested IAT, rpm acceleration, rwhp, tq, etc.

But looking strickly at max HP and TQ numbers here are the results:

1. Cold Air Inductions -(409.66 rwhp, 408.32 rwtq)
2. Airraid -(405.55 rwhp, 407.36 rwtq)
3. Late Model Racecraft -(404.39 rwhp, 407.03 rwtq)
4. Fastlane - (401.22 rwhp, 398.11 rwtq)
5. New Era Performance - (398.18 rwhp, 402.39 rwtq)
6. Advanced Flow Engineering - (391 rwhp, 387 rwtq)
7. ADM Street - (389.77 rwhp, 399.09 rwtq)
8. Baseline stock intake - (393.37 rwhp, 395.45 rwtq)

In the acceleration test (3500 - 6500 rpm range) Fastlane was the fastest followed by the stock airbox.

Interesting... I google'd this with no success, do you have a link? This is the second test that has the CAI at the top... Also interesting that mid pack HP intakes were faster in acceleration???

The test is in the May 2010 Issue of GM High Tech Performance Magazine. Its a 10 page spread with a lot of information about each intake (intake pictures, easy of installation, fit and finish, etc).

The baseline stock is the highest stock dyno I've ever seen...am I missing something here?

I believe the test was done at AntiVenom in Tampa Fl. They must have a very generous dyno.

Did the article say whether or not they did a tune to go with each CAI installation, or did they just add the CAI and run it on a dyno?

So my question is the hp gain by a cai is just for sound and bragging rights that your car makes more hp but in general everyday driving your car will be slower?

Cold Air Incuctions won Jannettys tests and now GM high perf. Maybe they have something figured out down there.

Hmmm. I need to read this article, because nothing about those numbers look right.

No mention of tuning done for dyno numbers. They did try to downplay the dyno numbers saying "that there is no way to accurately replicate real-world conditions for intake testing." Basically because the dyno doesn't show any "ram air" properties of each design.

Hmmmm, I was set on the ADM Street as well. Looks like the CAI is the way to go.

Damn! I just got my April mag!!

WTF!?!! lmao

How does the NE OTR "Feel" faster when strapped to a dyno?? That's what I wanna know.

Goes to show you that "peak horsepower" isn't always what people are looking for. Most of us won't be running in the 6000k RPM levels when cruising to work. lol

And yes, we need to see if these tests included any kind of tune or were just thrown on. The article is NOT online as of yet. I'll be watching for it.

They did an acceleration test from 3500 rpms - 6500 rpms. They timed how long it took for the car to go through that rpm range.
What they did is data logged runs (driving) from 3500 - 6500 rpms in 2nd gear (basically 40- 75 mph).

With each intakes it took the car around 3.8 sec (some slightly faster than the other) to go from 3500 - 6500 rpms. But all of the intakes were really close (within a few hundreds of second or so).

But this test leaves a lot on the table. Its not a real 1/4 mile run where you're going through all the gears from a dead stop to 110 mph.

I've seen that dyno. They put lots of stickers on it so it adds horsepower to your car.

If you look at the ambient temps you'll notice they were different for the road test. Stock was tested at 60.8 degrees ours was tested at 71.6. This makes a big difference in power.

I noticed that. It must have taken them a while to test all the intakes. They probably started out early in the morning and it got warmer throughout the day.

The temperatures ranged from 46 degrees (Fastlane) up to 73 degrees (LMR).

When the numbers don't make sense, there's usually an answer. I think we found it.

Yeah, but some of the intakes performed really well even though they were tested in warmer air?

But Fastlane did have the fastest single acelleration run. It also had the coldest temps (go figure).
