How much longer can you hold off running the A/C?

Seriously, I think we live pretty close and we have flirted with 80 a couple times now

I can hold off year round, even in 85+ degree weather. I just take my shirt off. Having cold water ready makes this a lot easier. The weak point is actually my dashcam which requires air to be blasted at it periodically or it may overheat and start looping the audio and randomly corrupting files. Now, when it does get that hot I will turn on the A/C during deceleration because its "free", but that does complicate fuel cut deceleration. With the A/C on, the fuel cut stops at 1200 RPM, A/C off and it stops at 950 RPM. I also open the windows at lower speeds in these temperatures, but that really doesn't hurt as much as the A/C.

I'll try putting some reflective material over the dashcam at some point to keep direct sunlight off it.

Indeed we do! I see you have already added yourself to the user map. I think I have seen as high as 84 according to my car's temperature gauge.

Gotta schedule another georgia meetup, we have plenty of people this time around.

Oh come on guys! You have to try harder than that!



What is going to happen when(if) I start engine off coasting, and doing the much more serious and visible mods?


Older brother wants to go on a 4000 mile road trip(and its not to pick up a motorcycle this time!), I support this, in my car of course. Ideally I will try to reign in speed and potential A/C use to keep mileage at or above 38 MPG, but we'll see. I don't know if work will let me take a whole week off without much notice...

I’m trying my best to catch you, lol... my commute sucks in that I have three hills to cross, one of which has an unavoidable drop to 4th gear(can’t take turn at bottom fast enough to use 5th)...

However I’ve still got some missing to do yet...

I am number five?! The only modification on my Accord is Gorilla Tape on the grill. I was thinking of finally doing modifications, but now that my brother dented my roof, it flexes above 50 MPH, so I am wondering for how long I keep this car, because that is an annoying noise to annoy this oyster.

Today was the start of me and my older brother's trip to Montana to visit family. It is supposedly something like 4000 miles round trip. Today we did around 900 miles. Since my brother is decidedly NOT a hypermiler, but is somewhat willing to compromise, we have mostly been driving the speed limit(70 mph usually) without A/C. The only tank so far yielded 39.1 MPG. I inadvertently adjusted the scangauge towards the wrong direction(pessimistic), but my despite that, my next shift of driving ended at 40.3 MPG(indicated). We'll find out tomorrow what the tank ends up being.

The grill block came off pretty early in the trip due to traffic and overheating, and will likely stay off for the foreseeable future. Thankfully my undertray has been holding up very well at high speeds. I don't even know its there!

Speaking of things I didn't know were there...



That would be the outline from a pair of pliers which have been hiding under the seat for about 5 months.

We stopped in Carbondale Illinois for lunch at Quatro's pizza. I neglected to take pictures of the pizza cause it was too tasty. Really looking forward to some Portillos on the way back.




After pizza we detoured to the Kinkaid lake spillway, climbed the path around the waterfall, and took some pictures.(can't access pictures yet)


Some scenery shots: (More will be added when I get back, some pictures were taken with a camera whose memory we can't access right now)







I have finally been shown the light as far as making pictures full size in forum posts, so enjoy the full size pictures!


5/10 edit: I INTENDED on updating the trip every day, but will probably wait until later.

5/17 edit: Made it back alive. We did 4805 miles in 8 days, and averaged 41.45 MPG over the fillups that are recorded thus far(about ready for another fillup as we got back).

I joined the warm air intake club today. That is 4" dryer hose. It was quite a challenge to stuff that hose in there, not much room in the engine bay with the V6. The hose is sucking air from right by the pre-cat.




Someone with previous experience with warm air intakes should chime in, but I expected to see the intake temperature rise fairly quickly. It was 55F outside and I hit 100F coolant temperature before the intake temperature even moved. The highest temperature I saw was 57F over ambient, which is definitely higher than normal, but not by much. My usual scangauge setup does not include the intake temperature, but I have run it before and saw 40-50F over ambient when frequently coasting in neutral.

I only took it on a short drive, so I will have to report back later with the full results. The tube wasn't as close as it could be to the pre-cat, so I moved it a little closer, but I probably need a shroud to get the full effect of the exhaust heat.

I admire the car. Think it a very nice choice.

As to 50-mpg? (Shrug).

The game is against one’s self. The recorded average. Consistency is planning. Planning is simply reasoned steps. Each one. But it’s done badly where cars are concerned. Short versus long term focus (as long term hasn’t the emotional content).

Example: 900-miles in a day. (Not good). Doesn’t matter there’s two drivers. Driver or passenger, 600-miles is the wall. Thus the plan takes place inside the legs of the trip. Each stop is beginning and end. Each stop is time & distance related. (Safety; an alertness fill up).

Best performance is in maintaining distance from others. This comes from cruising below the cars, and is awareness of the idiot packs. Cruise control is cancelled when that happens. Drift down fairly quickly. Re-accelerate on a downslope.

This is a rhythm that can be kept up all day. It’s a graduated response to conditions. (I do this for a living. Already past 120k miles this year).

I know it’s tempting to control every single possible action. But that is fruitless. The basics suffice. No lane changes at a constant speed. Never a barrier to others (watch mirrors and manage flow of others). Count acceleration and deceleration events. Don’t minimize so much as taper into & out of.

Look at your average speed. That’s the reality check for getting the most out of the 600-miles. Total trip time, and total drive time. They aren’t the same.

Find the reasonable time/distance equation for your car. What IT wants.

There’s a zen moment that hasn’t anything to do with MPG. The catbird seat.

My 9,000lb pickup can do 33-mpg at Interstate legal speeds. So what? (The average is from 24-27. What matters to me is that my average speed stays above 50-mph; though that isn’t at all the travel speed).

There are penalties for faster or slower. Neither gains me so much as hurts me (or my loved ones). Find the catbird seat. Let the miles take care of themselves.

Good luck
