Mods Face Off Result: AFE Stage II Intake

This test consisted of testing the AFE Stage II Intake on a completely stock 2005 300C and an extensively modified 2005 300C at the Mods Face Off 5 (MFO5).

Mod Tested: AFE Stage II Intake
Date: 10/12/06 - 10/13/06
Dyno Location: SVS R&D, Sacramento CA
Track Location: Sacramento Raceway, Sacramento CA

***Remember to always review and keep in mind the Mods Face Off Testing Methodology Q&A while reviewing these results.***

The Good:

• For the first time in the history of the MFO events, we have a group of intakes that deliver significant performance increases on a stock 5.7L; and the AFE was the second best performer behind the AirHammer. This guy averaged out a 6.7hp increase.
• The sound is a nice deep growl. Certainly louder than stock, but not something any of us found particularly loud. Probably just enough to have some fun with, but not enough to annoy the neighbors.

The Bad:

• While we did show an increase in hp over stock, we showed essentially no improvement in terms of torque. On the heavily modified 5.7, however, the gains were just opposite; that is we showed nearly no increase of horsepower, however we did see a fairly nice increase in torque.
• Based on past experience, the filter size might be the limiting factor here. We did not test a larger filter, however, to see if it made any difference.

The Numbers:





The Graphs:

These two pulls closely follow the averages for the entire set. This is average vs average, not worst vs best.





COMPARISONS:

Intake STP Horsepower Comparison - Stock 5.7L



Intake STP Torque Comparison - Stock 5.7L


Intake STP Horsepower Comparison - Modded 5.7

Intake STP Torque Comparison - Modded 5.7

nice test, thanks for the info. I only wish there weren't so many variables. I would have been cool if Meister's base test could have been with a stock air box but none the less thanks for all the time and effort.

I've been thinking about getting one of these CAI. what size was the filter being used for this dyno? what's the next size up and will it fit in a Charger? thanks again.

While there are a ton of variables, most really do wash when you're testing like we test. What matters here (as it has always mattered in the 4 previous events like this one over the past year) are the relative differences. Relatively speaking, this intake performs well. What specific HP and TRQ increases will you experience? Only you can test that. But what we can show you is how this intake stacks up, relatively, to other intakes. That is a very powerful concept, the results of which are incredibly useful.

The filter used was the filter that ships with the system. Remember, we're about testing intake "systems". We're not in the business of showing OEMs how to better their products, although many have changed their designs as a direct result of our tests.

Do we have anything that shows us how Meisters custom setup compares to stock.

[CoolVanilla]

Well, we do. But you'd need to dig thru some of the past GIFO test results to find it (which you're welcome to do!).

I'd also suggest that testing a stock box on Meister's car would be almost silly; IMHO few, if any, would make the mods he's made and stick with the stock box. The choice of his intake as the 'baseline' was my choice, and is arbitrary in terms of results (in terms of political correctness, it makes sense as it does not favor any company over another). I suppose we could have thrown on the stock box and base lined off that, but in all honesty, that didn't even occur to me. And upon further thought, I still state it matters not.

As I get to more and more results, and then produce a summary table, it will become clear how each intake rates, relatively speaking. Unfortunately, this takes time though.

your probably right in saying it really doesn't matter that you didn't use a stock air box in Meister's dyno. most people with that many upgrades probably don't have a stock air box. the test you guys performed produced great results.
the only thing I was saying is that since in the second dyno two variables had changed there was in reality two different sets of dyno's. being that the stock air box was not used in the in second dyno the results are not really comparable to the first due to the fact that the custom air intake changed the rate of air flow other than what the stock box would have. since we don't know what the the HP and TRQ would have been with the stock air box in the second dyno we can't really compare it to the first.
of course I know this is incredibly anal of me and I did not mean any disrespect to any of you and the hard work you put in to this project. again I thank you for all the time and effort you guys put in to this, it has been a real service to everyone on these forums.

Ah wait a tick... I get what you're saying now. We aren't actually trying to compare the first to the second. Take a close look at that data... we actually aren't trying to compare stock to Meister's rig.

These are two different tests wrapped into one. Our goal is to show what this intake is worth to someone with a stock 5.7, as well as what this intake is worth to someone else with a modified 5.7. They really are independent things.

Does that help clear things up?

[pdogg57]

absolutly, great tests vanilla, can't wait to see the summary table! thanks for all the numbers man, they really do help.

[broc2238]

That's pretty impressive gains there. While peak TQ doesn;t seem to be up...Look at that dyno curve and see just how much extra torque there is above the curve

[pdogg57]

hey coolv,

what were the manometer results on this intake?

[Kim Hufty]

This intake is making good low end horsepower and torque for a stock RT for every day driving. The airhammer is making more horsepower above 75mph.
Can we make that kind of comparison with the MPH dyno curve to street driving???

First post updated with summary graphs.

thanks coolv! great numbers and graphs!

Do any of these test show a signifigant rise in MPG. Back when I had a 2000 GTP (Pontiac) I used A Thrasher CAI. This netted me around 4 more MPG. Has there been any testing done on this? If not with today's gas prices this would probably sell more CAI's.

[MattRobertson]

While some of our tests involved long drives when we were still looking to see if adaptives played a role (they don't) we were focused on performance.

If we did mileage tests in this day and age the budget for the whole event would go to gasoline :-(

I personally have a 310 mile daily commute so my car would be a perfect test platform... except its nowhere close to a stock motor, and again driving it instead of my gas-sipper would be kind of expensive. The test series would have to fund about $40 per intake tested (thats the diff in fillup costs). And we'd be testing on different days (hence different conditions).

Its worth thinking about but I don't see how we can do it and factor out the difference in weather day-to-day.
