not complaining! but I just filled my FB up for the 2nd time and I got 34.8MPG.

/best/ rx7 milage I've ever gotten, BY FAR!

2g dfis seems to have helped, it's otherwise bone stock.

first tank I only managed 24mpg.

 

34 mpg?! I'll believe it when I see it

 

ya that sounds way too high. 2nd gen ignition helps... but not that much!

 

that cant be right. thats 7 mpg more that ive heard any rx7 getting and about 12 higher than ive seen personally. are you sure you caclulated that right?check it a few more times to see if you continue to get these results.

 

Is that 4.5 liters per gallon or 3.78 liters per gallon?

I've done 30 miles per 3.78 liters before, and I considered that to be extreme asskickery...

24mpg is on the high side of bone stock, too.

 

Wow, that.....doesn't seem quite right. Are you sure someone's not putting gas in your tank when you're not looking?

 

ya, no kidding. way too high. I've gotten ~24 on the highway, and when i'm pounding on her i get ~6mpg, but it's worth it.

 

you didnt happen to coast for 100 miles or so downhill with the clutch in and the engine off did you? damn, my car gets about 18, even with the 2gcdfis. Congrats if its true.

 

My dad's racecar got 26 highway... probably better now (but more illegal).

 

i'm still calling "wrong gallons".

34mpg Imperial (4.5l/gal) is 27.2mpg US (3.78l/gal) which is still rather good for a carbed rotary.

24mpg Imperial is 19.2mpgUS which is about average for a carbed rotary.

Common problem to deal with. It's why cars you read about in magazines from the UK seem to get such good fuel economy, Imperial gallons are larger!

edit: those numbers are imprecise, i used the wrong conversion factor, but they are close enough for illustrative purposes, running late for work no time to fix

 

Perhaps if you were idling on the back of a truck which was driving down the freeway...

 

Wow, impressive. I manage that while my car is in the driveway. So what do you get on the road?

 

i'm calling shenanigans! he was towed behind another vehicle! keep getting that kind of mileage and it's time to swap out your mazda logos w/honda's...nobody desires that..so here's to getting back to lousy mpg! cheers!

 

as my girl sits she is getting 19mpg w/ a sterling carb and straight pipes. Tho car has been shaved by 250lbs. I am hoping to get over 20 with the 2GIDFISwTT. Before doing anything with the car I got 24mpg. You pay the price for preformance. Also to note initially when I did the sterling swap I was getting 15mpg w/ stock exhaust and untuned carb (great fireballs and backfires).

 

Ah your car wouldnt happen to made out of carbon fiber would it?

 

yea that's a bit insaine, i get 19mpg's on my stock 84 se

 

well according to my lil mile tracker, i get a good couple hundred miles to the gallon.. also that in 15 minutes at 60mph i can go about a hundred miles, hows that math for ya, hehe

 

Gr8 work i manage 1mpg backing out of my driveway and 0.3 on the highway
LOL

nathan

 

I put gas in when the gauge tells me too...

 

exactly
