Gas mileage, what you getting?
 

In my '89 GTU, (S5 mild port n/a, with RB mufflers an presilencer, emission's removed, AC components removed, aux sleeves an actuating rods removed, vdi open, heat-shielded cone air filter, 1/2oz. per gallon premix.) usually the range is from 18-25 MPG.

But with the latest tank, I got 27.6 MPG! Which is the highest I experienced in this car.

On a regular day, the breakdown is probably...
With city driving, I get about 18-20 mpg.
Hwy & city, I get 20-22 mpg.
Out of town RX7 meet or out of town trip, I get 22-25 mpg.

But the latest tank I did, out of town trip, and hwy & city driving.
Averaging 70 mph on the hwy.
And got 27.6 mpg.

Someday...30mpg...someday. :D

I'm getting 18-20mpg city (15mpg on good days) and up to 25 hwy.

Intake, RB header, midpipe and HKS 52mm catback. Pineapple Aux. sleeves, SAFC (tuned to 11's = ~ 150rwhp), no premix, Avg 75mph.

Good numbers BTW. 30 MPG seems doable.

I'll post up my stats once I'm back on my home comp.

Right about 14 - 15mpg strictly city driving...
It'll creep up to about 17 - 18mpg once I start jumping on the freeway more.

I get about 18mpg combined, 22 on the highway.

s5 13bt + stock turbo
12psi + stock IC
RB turboback
MT LT8-s
~230whp

all hwy driving without opening the secondaries I can get slightly over 20mpg (roughly...I'm converting from Km's) but when I'm denting the floor with the loud pedal its closer to 10 :( But it (was) fast as a scared monkey.

Avg'ing right around 20-24mpg on a stock block with out emissions running a RB header/presilencer and a straight pipe into a cheap ebay muffler, SAFC with about 10% fuel knocked out at idle to -4% at redline(still need too actually tune it better), an intake leak of some kind, either a gasket or one of the lower injector grommets, no ac/ps. And average MPH is 80+ during interstate travels and 60ish around town. 1-2 gear is always redlined before a shift, and sometimes 3rd as well. But i hope to better my numbers soon with a better CAI, instead of the cone on the end of the intake tube in the hot bay. Car also has an FD alternator an a ford escort Efan. Still need to get around to getting a cleaned/flow tested set of injectors installed and tidying up things but its driven everywhere I want it to go.

I call BS, brother.. i bet the gas pump was not calibrated right. the best ive seen is 24.5 which was mostly crusing at 60mph, i usually get 16 mpg city. rtek 2.1

I believe 27.6 all highway. I get 24 mpg all highway and that's on an untuned N/A. A good tuning on a TII that stays out of boost can hit that. Now whether or not he actually got it, who knows. But I say it's possible.

I do not dive mine enough to keep track that well, but on the way back from DGRR, I averaged 28.5 MPG.

S5 TII, no emissions, RB DP & silencer, Apexi N1 EVO catback.

I've gotten 26-27 in all hw driving in my vert. It is possible.

I've gotten calculated 28mpg, and it should've been more like 30mpg cause I didn't drain the gas tank all the way down.
The trip OD hit 400, and typically fill-ups were about 13 gallons - you do the math.
Since I was doing such long distance driving, I wasn't going to take a chance and drain the gas tank that low - i.e. the fuel-low warning light never came on.
If I really wanted to push it, the car would've easily hit 30mpg.
This is driving between Sacramento, CA and Las Vegas, NV 100% freeway at speeds of 60mph to 80mph, just under the point where the secondaries kick in at 3,500RPM.
Back then it was stock ECU (well, reprogrammed G-Force unit) with full exhaust on a 1987 Turbo II.

Side note, I was able to hit 200 miles on a 10 gallon fill-up's.
I only fill up 10 gallons at a time, and it makes calculating mileage easy now.
Still tweaking the Haltech E8...

fellas, hook me up in this thread:
http://rotarycarclub.com/showthread.php?p=35564

well i did some more data entry, check out some of my recent mpg's:
21.6163311
22.7419719
23.6608230
20.9012464
23.6247829

I get 11 mpg.... fuck all of you.

Time to go stand alone and rebuild time.

(The car is running 10's in the AFR range and I am SEVERELY heavy footed. I love my boost.)

You're just a hater.

you're getting a happy 11mpg. If we were to calculate happy MPG we'd be in your boat.

hey! I resent that! That's just my driving style! In town i get 10 to 11 mpg.

yeah and I bet you're smiling everytime you're boosting with the pedal all the way down.

If you're not then those aren't happy mpg.

Well once the engine is back in im sure he will be, it's a little strange boosting with half of the compressor wheel intact.

I would be smiling if I had boost when i pushed the pedal anywhere. I'm NA :(

Oh, I smile alright, then fill her up with premium and I am still smiling.

It's worth it.

Well, I was disappointed with my mpgs last Saturday.
I went to a rx7 meet in the upstate, drove around an in the mountains.
I got gas once when I was up there, then yesterday.
Results: 22.6 and 23.2

Well I guess thats my norm.
I was hoping for 25 or better.

Gosh.. I "feel" like I'm getting 12-14MPG in my T2 vert. If I wasn't so cheap and just top off the tank, I'd find out. Stop putting in 20 bucks at a time! lol

But I like keeping the needle around 4K in 3rd gear.

90 GTUs 4.30 gearing

15-16 city
18-22 fwy

without a tune on my fresh build...umm i say about 5mpg city and 10mpg highway. jeez thats horrible

im getting about 20-25 between city and high-way 13b non turbo. oh yeah does anyone know where i can get a drive shaft with replaceable u-joints

www.mazdatrix.com

305 for their serviceable DS.

22 mpg the same is my f**n millina. BUT runs off of premium plus

my fiancee's vert gets about 20 with the top down all the time. The turbo im not too sure. I think above 20 on the freeway.

My latest fill up, I got 25.6mpg.

Toby you should come by and see the project. He is finally running and we acquried another turbo. Black and fully kited.

I get 12 to the gallon. 90 Turbo with TO4B 60AR ball bearing garrett turbo, 1000 secondary injectors, 680 primaries. Large street port. SAFC 2 with AVCR. 433 gears in the rear. Yeah, not cheap. I go about 200 miles on a full tank. Anyways,,,, yeah.

On average I'm getting about 9/10mpg in the city. about 24 on the highway.

Thats with running excessively rich.

wait what rotary doesn't run rich...LOL

Actually, my '86 ran very lean on the Haltech (16.2:1 while cruising)

I could easily exceed 30 mpg with it.

I got about 28 or 29 running around town (driving it like I stole it).

Not too bad for 165 rwhp!

The '91 gets 20 city and 25 highway (best was 27.2 mpg).

So a couple weeks ago I took a trip up to Durham NC for a rally-x.
Before I left I filled up my tires to 35psi warm.
I got 28.0 MPG!!!
Then the next tank was 26.4 mpg.
I normally don't think of over inflating my tires, but now I do, lol.

My all stock '87 TII gets btwn 13-18mpg. My '83 race car 13b n/a gets about 7mpg est. ALL FUN and SMILIN' ! ! Friend of mine gets 25mpg in his '83 12a n/a. 80mph highway road trip.
