when the field mice eat a hole in your stock intake........It's it's time for a CAI regardless of Brand or advertised results...........

Damned mice, cost me a small fortune.......Intake, radiator hose, windshield washer reservoir, insulated jacket on PCV line.

I'm curious, any independently generated, comparable before and after dyno figures... not supplied by the company selling the product? I asked because my dyno guy said it's easy to "tweak" the dyno output to produce whatever you want it to look like, if one should wish to do so.

Ratman, that sounds like solid logic!

Wow ............. Almost two years since the last post to this thread ..........

We use a SuperFlow wyndyn dyno. Anything can be tweaked I am sure, but it would not be smart since everyone and their grandmother is on social media. We are not the manufacturer of the Green but helped them in getting the diameter right. For us it didn't really matter at the end of the day as long as it was right.

I'm in possession of the latest VARARAM! C7 test unit. I'm always impressed with the products that Patrick @ Vararam puts together.

Hey holds them back and plays with them till their perfect.

Hopefully over the holidays I'll have time to do a before and after comparison.


Keep watch!

Chuck, Veterans do not get ID cards. The only ID cards are for active,
reserve or retired. Not really sure why but any veteran does not have them. They have a DD214 but there is not a picture on it.
I was replying to what is in your signature.

ID cards for Veterans are supposed to be available this month. Just as vets can now shop at the BX online. Retired have ID cards also, btw. Haven't seen details on how to get the IDs as of yet, hopefully coming soon. A lot easier than carrying a 214.

MikeyTX

As bad as trying to carry a DD215.

C.A.I. they do make a huge difference on HP and sound on a S.C. engine but no difference on a N.A. engine.

Actually they do make some difference. I believe the gain is worth the expense but not everyone does. I have spent more for less so I guess it's a personal opinion. The fact is that the car will pick up at least for the Green and the Attack Blue that I tested.

When NPP was an option in 2014 I paid $1100 for 5 hp and “noise.” Most think the NPP 5hp and “noise” is a good value.

I paid <$500 for my low restriction larger air filter and reduced restriction inlet air duct. The minimum I got is 10hp using data from another poster who had his car dynoed before and after install of the same low restriction system with that companies more restrictive paper filter versus the lower restriction oiled cotton filter I purchased. I problably got 12 to 15 hp and perhaps not the ~17 hp they advertise and for which they show dyno proof.

So even if I got only 10hp that’s 4 times the hp value and the intake makes almost the same “noise” as NPP at WOT!


PROOF OF LOW RESTRICTION INTAKE NOISE

Tadge in a forum post said aftermarket intake folks don’t have to live by the noise restrictions they do for every State and counties overseas. He said intake noise is the next loudest they have to deal with in drive-by noise tests!

For the 8.2 Liter BB in my ProStreet Rod the 14 inch diameter, 5 inch high K&N oiled cotton air filter makes as much “noise” at WOT as it’s long tube headers going through 3 inch pipes and straight through Borla mufflers!

I agree with the last sports car had a CAI on it! They didn't do anything to a 2002 Z06.. The C7 Z06 is different. Not worried about results on a C7 since I don't have one. But on the Z06 the intake is a big thing and nets more hp than any bolt-on.

Around 40 rwhp plus from a Halltech intake with every unit installed on the C7 Z06. If you say different you don't know what you are talking about!

From reports others have said the same, BUT they also say it requires a tune! With that much power increase can see the existing air/fuel MAP cannot adjust for the needed change automatically.

That is not an issue with the 10 to 12 hp gain in a NA LT1. Had my aFe for 3 years in my 2014 and now ~6 months in my Grand Sport (same system removed from my 2014 before it was sold.). No CEL and car runs great. Great “sucking” sound at WOT as well!

Tune means warranty issue, no tune no problem (at least as I am concerned.)

Just a point of clarification, all C7’s have CAI, (cold air intake.) Air comes from outside the inner fender panel. There is a passage between it and the outer fender well that comes from the front of the car before the rad! Cold as it gets! Best called lower restriction systems (LRS, my coined word) Mine uses a larger oiled cotton air filter that requires a large filter enclosure. The aFe also has a less restrictive air tube.

I'm just going back to the original question I had... It's a freaking pipe and a filter. All this money they are charging and no one is willing to produce one that is CARB legal. $500? You gotta be out of your damn mind to buy one of these?

NmtMev

might as well but one of these. Save some coin. Instead of a window it has a filter life gauge. It come with a dyno sheet to prove it makes power. And you will get your sucking sound!

village idiot

I've said this a few times- running at the track for 30 min sessions, my stock air intake temps never went above ~5 degrees of ambient.

Any gain is coming from a less restrictive air filter- which means it's also letting more **** into your engine. Tadge said they tested these filters and they didn't pass for just this reason.

That and the "tune." The reason you need a tune to see gains with a CAI is because the tune is the thing creating power. There is no reason why a CAI would need a tune- everything is before the MAF/MAP/etc. It's like saying you need a tune for when it gets a few degrees colder outside.

JerryU

Hmm, guess you didn't opt for that $1100 NPP that gave you 5 hp and "noise!" Can't understand "how you can say it's just a filter and a pipe!" Pay ~$60,000 for a car and obviously don't understand engineering, design, testing, manufacturing and other costs or business!

From my other post:
When NPP was an option in 2014 I paid $1100 for 5 hp and “noise.”

I paid <$500 for my low restriction larger oiled cotton air filter with molded larger filter housing and reduced restriction molded inlet air duct with integrated helmholtz resonator (like the OEM) with required stainless clamps etc.

The minimum I got is ~10hp and "noise!" Got about the same "noise" level as NPP when at WOT! 4 times the hp value!

Some of the new filters have tested better in the ash test than the factory filter. So that statement is not true for all of the aftermarket.
