New Mod Made ***7mpg***
Stock, I could not get over 35-36mpg even with an empty car on the highway. Around town, driving agressively, I've gotten as low as 20mpg.
A few days ago I put on my home made $40 short ram. I was on the road today for 8 hours heading down here to Gulf Shores from Memphis. At one point with some slowing and speeding (and a burst to 100mph to pass a couple trucks) but setting cruise at 75mph, I got 40.5 mpg with about 500lbs total baggage and people. AMAZING!! I never got over 36mpg before this. Then after that, on a more stable portion about 150 miles long, set at 75mph, I got 43.8mpg!!!!!! I am shocked and amazed. Here is the thread about my SRI: https://www.fitfreak.net/forums/fit-...am-intake.html http://www.speedsoutheast.com/pp/data/589/DSC_25591.JPG |
Another Memphian?! I didn't think anyone else here lived where I live. We needa meet up some time.
And I wish I had thought of doing a piece-together intake. So much cheaper price-wise... |

Are you Kidding!!
Not for nothing... you simply can NOT double you miles per gallon by simply replacing the air box with a cone filter...
Plain and simply, its not possible.... |

So two threads about a sri? This one in the wrong section. Cool
|
even so, I can understand gains of 3 to 5mpg from variability of driving behavior, but i can't comprehend a 7mpg gain on just this cone filter mod...
I can see 1 to 3mpg gain Cold Air Induction or Ram Air Induction, but not this mod.. Infact, you're probably hurting performance. All the air your sucking into your combustion chamber is HOT air from the engine bay... |
who said Double???? yeah true I can probably drive in first and second all day and get 15mpg pooo, and then suddenly use 5th and get 30mpg!
I probably would have put this in the mpg thingy thread...maybe a mod can move it. Congrats on the findings, I would like for you too keep us posted (are you buy chance planing on getting a scangauge? That would be an interestng combination, that might clarify some results for ppl. |

Heck even some of the FI guys are saying higher MPG's (which makes some sense, but still blows my mind:eek: ) maybe its not so bad, as the grill (i think...have to go check) is right infront of the filter so maybe its constantly getting a decently cooler flow of air....whadduya guys think? And it is probably breathing easier...hmmm... Heck it even sounds like a fun to do mod. If you are not getting lower (average) mpg's and the car is not "over heating?" or sucking in crud....no harm no foul right?:o |

Plain and simply, its not possible.... And I have 5 people as witnesses to this mileage. I am amazed and shocked as I stated. I have been in the retail performance parts business for 10 years and I have heard of very few cases of helping out mileage like this. But it is in the realm of possibility. It can happen. Now if I said I was getting 55mpg, then I could understand you calling BS. But this is the truth. And how is this in the wrong section? This thread is about mileage gain, correct? Which forum should this be in then? |
Did you test your city mpg with this installed. I may have to get this if your city mpgs went up a lot.
|
I haven't driven it in the city yet, but I will let you guys know when I do.
|
i figure it increases you highway mpg but your city it think will see a drop. My reasoning, highway is pretty steady driving unless passing,
but city its going from neutral to 3000 lots of shifts and down shifts (esp with revmatching) and speed changing. |
OH...I was just thinking it could go here-
https://www.fitfreak.net/forums/eco-fit/ it sounds like a good fit for that forum;) |

I can see how someone might see these gains with an improved intake over a stock/restrictive intake, it would reduce pumping losses and increase the ability to suck more air. Pumping losses are a very large part why intakes improve power output, because if an engine has a restrictive intake it takes more power to suck air. He is claiming ~13 to 19% increase in fuel economy which I can easily see happening from an intake, expecially one that is as restrictive as the stock fit.

Thanks for the props.

Back to subject, cool findings with the short ram |

Actually, colder air is denser, increasing the air to fuel ration, requiring the ECU to respond with more fuel to even out the mixture...therefore increasing fuel consumption.
WIth this mod, although your increasing the surface area of the filter, you're sucking in Hot air, which will give a less complete combustion. This will lead to unburnt gasses... On another note, the way the ECU responds is differrent from what you stated. If you do a mod like CAI and don't reset the ECU, the air to fuel ratio will be the same. If you reset the ECU, then you will remap you A/F ratio.. |
