MPG numbers on highway

[4CYLPOWER92]

My h22 at 60 gets only 31mpg

Thats about what I get also, even up to 70mph with h22 and h22 tranny.

[bcjammerx]

ONLY 31? That's pretty damn good

[MikeW]

Im so happy, lol

I went 350+ miles on a trip this weekend and i averaged 28.5 MPG.

About 250 of those were highway, no AC, the other 100 was city, with 50/50 AC.

Not bad compared to my usual 22mpg City.

[Shag Wagon]

I average around 25 mpg in my wagon. But I have a semi lead foot and automatic. I wonder what the f22b1 with jdm h22a automatic will do.

[MikeW]

Im AT and i used to lead foot, but ive eased up lately. Still getting 22-24. Althought it IS all city. I rarely see anything above 50mph.

yeah for some reason, my city mileage sucks BIG TIME, sometimes its 19, sometimes 21, but idk how other Auto guys manage mid 20s in the city. Its either ALL highway for me and net 30mpg or 19mpg in city lol.

70-75 is where I get the best gas mileage. Trying to do 55-60, just doesn't work out. Kinda baffles me also, knowing the engine's running faster, using more fuel at 70-75 than 55-60. Maybe cause it's a Honda? 1 day they'll start up. One day they won't. Next day, start right up. The fun!

Well it's ALL about distance and fuel used, so if you can go 20% faster but only use 18% more fuel, then you will get better mpgs. It's the 'sweet spot' they always mention.

not just you, mind you we have the heaviest cars aside from wagons, maybe se's..our 93 ex's are about 3100 lbs! I constantly see 21.5 when I have places to go and can't be bothered with hypermiling around the city. However my mpguino shows if I can get it up to 55 or so it will improve to about 25. 35-40 is not such a great spot for my car. And again, with the weight, having to constantly reapply the throttle to regain speed just saps the mileage away.

BUT.....BUT.... I've got a CF hood! lol. Yeah i guess city mileage is sucky for our cars since they're the pot belly pigs of early 90s hondas compared to other civics and CRXs etc. I could inflate my tires to like 44psi, but then they'd wear out quicker. And at 546 dollars a set, i'm not so keen on doing that. I keep em at 35psi right now, about 40 when I take a road trip.

hmmmm, I need a vortex generator like on the Evo 9s lol.

But have you done tests as to which speed the F22 engines are most efficient? I know they won't be all the same, since every engine has its "sweet spot" but what would you think an F22A6 sweet spot would be? like 75ish?

hey losiracer, when you're going say 80 or 85 wat is your rpm at that speed?

Mine is about 3.5k rpm.

Seeing that makes me feel like my car is drinking gas haa.

Just wondering if this is right.

yeah i'm at like 3450rpms so pretty much 3500 at that speed. At 70mph, i'm at like 2900rpms. I was also pondering if I should use a colder plug for my climate. Like a NGK ZFR6F-11 instead of the 5F-11 i've got now. Since it's so hot over here. After I did my HG, my engine seems to run hotter. Maybe b/c the compression is back up to 180psi instead of being at 90psi. Idk. Still some things to figure out. And my cooling fans don't come on anymore after my car is shut off....yeah still messing w/ that sorry for

[ikayto]

oh ok thanks for the confirmation I thought my tcu might have been whacked and I should actually be at 2k rpm or something at that speed.

As for spark plugs, i'm running whatever honda sells at the dealership.

It's funny, when my car was stock my cooling fan would turn on all the time. Ever since i got bolt ons it rarely does.

Header dissipates heat better? Bigger exhaust piping runs out the fumes better? Cold air intake cools engine?

who knows lol.

i drove from maryland to cali this summer and prob averaged around 35 mpg doing abt 80 most of the way cruise control set
