I registered on my first car forum in 2002, I've seen thousands of mods and their dynos. I've also built my own motors, turbo'd my own vehicles, and tuned my own vehicles with standalone ecu's, aftermarket sensors, and widebands.

 

That being said, I see no reason to believe the information was fictitious. Saying you never seen a vehicle gain that much from an intake does not prove anything.

 

Is it "holy shit" yes

Is it so "holy shit" you can consider a test from a reputable source and has nothing to gain by bias to be bullshit, definitely not

 

I mean for ****s sake, they even stated that the intake that performed best needs almost no tuning when their primary source of income is infact tuning. They provided people with an ability to make 36hp and not see a nickel for the sake of honesty.

I'm sorry, but I'm not buying into 36hp from an intake. Maybe a tune and intake.

36hp without tuning for it? That sounds suspect. I hope it isnt because i randomly bought one on a wim while xmas shopping for someone else, and a full morimoto setup for my 15. Just havent got around to putting it in yet.

Peak hp goes from 291 stock to 316 with the AFE. That's 25 hp. And that's at 87 mph.

I'm not buying it, unless these trucks are the only vehicles that respond to a "cold air" intake. If you go to any real performance forum they will all say the same thing, cai's are more for sound, and that's based on hundreds of tests over many years. Like was said earlier, factory intakes and exhausts are not restrictive to what their bolted on to. A 355 hp 5.3 intake and exhaust will flow 355 hp, like wise with a 6.2. Does anybody really think any manufacture would make a 456 hp motor and restrict it to 420 with an intake and by doing so loose gas milaeage at the same time.

I understand what your saying... but I really doubt blackbear would make false dyno runs..

So the airaid tube alone does very little??

It give you a crap ton of room, that's a huge benefit. ;)

GM is not leaving 36 hp on the table. That's just ridiculous. I'm sure Blackbear didn't do anything malicious...but there's something for sure flakey with their data.

Yes I do. That way in a few years they can "tune" things a bit and with that same engine put out more HP and fuel economy, but until then can still milk it for what it is putting out being somewhat more restricted. This has been a common practice for many years, I believe.

25hp and 18lb ft according to the chart. Still the best power producer tested. Timing was pretty advanced compared to the others, that could explain the hp.

Nothing fudged in the data, the dyno graphs are there for proof. Just like all the fellow enthusiasts out there, we too wanted to know if the aftermarket CAIs were providing any benefit to the newer vehicles.

So, no tuning was done, just oem intake off and afe on?

Wow that's impressive considering a stock tune. Maybe the next to do mod if the dealer ever gets the torque converter/transmission issues sorted.

As a reputable tuner, you yourself should question those dyno results. I can't believe anybody that knows much about cars thinks an intake tube would gain 36 hp. A high flowing intake manifold has never gained that much power...a good cam swap gives 50-60 hp and would require tuning...that tube isn't much different than any other tube on the chart...

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.

      Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
