Or, just the simple hose from air box to hot area that's been shown to have positive results. Maybe overthinking it, but I do agree if it is an issue keeping cool air out of hose, the atw Intercooler would also be a very viable option to control the warm air. I actually think my atw is too big to fit in this engine bay anyway. A small one would work tho

The I/C would probably extract more heat from the coolant than the heater core due to its size.
Except for the added thermal mass, I don't expect a noticeably longer warm-up. The heat is drawn back into the engine after all. |

That's true, never considered that. Thats why your an engineer ( I think anyway) and I'm not. I'm just a business guy. The technical stuff you guys can explain to me ;-)

Another thing...
Our engines have EGR, so in part-throttle cruising, it's likely that a fair amount of the intake charge is 300F+ exhaust gas. This won't show up at the OBD port since the IAT sensor is integrated with the MAF. You'd probably have to install an IAT sensor in the intake manifold to monitor this. |

intake location. i can actually push it down a bit further if i need too, it looks like it should be blocked from the pics, but if you go look under your hood you will see it is actually open to the back of the engine from here
yesterday morning here is yesterday afternoon after moving the hose in further, as you can see the fuel flow has dropped by nearly 20%afternoon,!!!! no real changes in weather conditions last night on the way home. no real changes again so far it seems to work Ignore MAF readings, they are beta and definitely don't work correctly in cfm mode |

BAM! 29.13 MPG average with this intake setup!!! not quite summertime highway, but summertime average!!!! the 2nd to last fillup was with the scoop for the CAI removed and my first testing with the hose setup. last fillup is 100% with how the pics are now posted. this was 91e0, but only because I was filling my gas tank for the snowblower too. Real test will come on sunday

FlyBoy, where are you located? I know driving conditions such as grades and whatnot do contribute too. Here in the Pittsburgh area, we have lots of hills, so our city mileage is generally worse than if you're somewhere flat too. On my first fill up with 93, I'm hovering right about 29 with average speed being 43 on the on-board reading. It's been between 20-40 on average for this fillup. I wasn't trying the 93 for any potential mileage increases, but to my surprise, it's still right about the same if not a touch better than on 87. Interested to see a few more fills.. CVT here.

The whole tank wasn't e0 so e10 numbers should be close, either way like I said it was like 3% difference so 28.3?. Sunday-wednesday next week no forecast highs warmer than -10F. Eff me, but should be a good test for this setup. |

The car does "seem" to run a little smoother on premium though.. Maybe it's just mind game witchcraft though.. haha I've always had cars that ran 93, so the extra cost doesn't really bother me. I'd rather pay the little extra and the car run top notch.

It is really a waste of money though. I haven't quite figured out the timing advance on this car, sometimes it is 30 degrees at cruise, sometimes it is like 21, same fuel and weather conditions

Should I be actively avoiding e10?

So I was thinking about air density this morning on my way to work, obviously no way to change it, the numbers seem small but the difference between +80 and -10 is an increase of 17%. I suppose that would mean the resistance would also increase by 17% or is there more to it?
I should see about 20% better mpg I think, but instead of say 29 mpg I would see 24 when the temps go stupid again? Ouch, but I guess it is much better than the 18-20mpg I was seeing on the interstate. I might need to drive around town more to boost my mpg Find out soon I guess :/ |

We were running about 9:1, not too high for boost. I think it was around 25 lb boost where it lifted. Just too much timing, they didn't know how to tune for E85 then. It was still new to that market. I had no idea either, that's why they were doing it.

Air becomes more dense as temperatures drop, which increases air resistance. For every 10° F drop in temperature, aerodynamic drag increases by 2%. Thus, fuel efficiency will drop by 1%. Overall, fuel economy tends to be higher in the summer than the winter. This was copied from an article I have from Cummins. |
