400+hp guys whats your mpg
i just went for a fairly long drive and noticed i was getting 130 miles on a 1/2 tank driving normal not running to wot or anything just curious what others were getting
street ported motor with r-85 single turbo 850s and 1600 injectors |
i get about 17-18mpg cruise on my 550/1600 setup. when im on it 10-12mpg.
|
mines not good 12-15 i have the same setup as you the 550's 1600s r85 lol... im goin with the 850's soon so i really dread the days ahead! the rotars are filty thersty lil machines ;)
|
Mines mid to low 20's I run 550 and 1200 and a GT35R. Thats just highway driving with no boost involved.
|

|

Most tunes are still way too rich for light cruising. You can easily lean out for some better mileage. It won't hurt anything.

|
i dont know how many gallons our tanks hold but 130 miles out of a 1/2 tank was like 14 mpg, i didnt boost past 5 psi for the 130 mile trip and i dyno at 420whp on pump gas
|
20 gallon tank...
|
WHEN my stocker ran. on a DP and CatBack no seq. 18 ish spritied driving. 21-23 hwy/city mixed like a "normal" human being. If i kept constant WOT i'd get 12-14...
but i kept good plugs in. changed em every 2-3 oil changes. Los |
you can lean out the vaccume section to bump up your MPG a lil bit
|
When I filled up yestarday, 20.75 mpg - right at 300 rwhp - and I boost daily.
|
3.5 mpg 850 1600

Rotarie are thirsty but as s tated , much more into boost. Reason to me is, singles get better mileage because the boost comes up at higher rpm and provide you a wider low rpm range to cruise and stay out of boost.
That's why i'm starting with going non seq and have it properly tuned. |
For the most part your porting and tune is what's going to effect your mileage. Not a particular hp number. Those of you with extra overlap on your primaries and to rich an A/F mixure under vacuum are never gonna have good cruising mpg. Why? Too much of your fuel is being drawn out the exhaust and waisted. You just have to know what your doing and have specific goals in mined when your building these cars.

That's why i'm starting with going non seq and have it properly tuned. So so right. Hell I can't stay off boost with my seq because of the quick spool. As soon as I hit boost (even slightly) my mpg goes to shit. That's why when I rebuild my engine, I'm going Gt-35r with higher compression 9.7 rotors. This should still give me decent bottom end while not hitting boost too soon, therefore giving me better around town fuel economy. |
402HP on 850/1300: T04S,...
I get 15-17 Freeway, and low 11 MPG city driving... |
440 whp, 15 highway and 10 city on a good day
PS: dont buy a FD if you are concerned about gas mileage |
about 20mpg highway when i can keep my foot out of it.
550/1680 |
I get around 260-290km out of one full tank. I have 850cc primaries/1600cc sec, but who cares about mileage it's all about the boost!
|
I was constantly getting 350-400miles from a tank of completely off-boost (ideally no more than -0.2bar) with over 400@wheels (550/1680). Same mpg I got with stock twins on stock injectors for the same driving - it's simply down to the fuel map on cruise and how smoothly you can use the throttle.
|
Damn you guys be getting some good azz gas mileage. I have microtech LT-8 and I even lean it out a lil' bit more to see if gas mileage will make a difference... I'm wandering will the HKS Twin Power help at all or not much of a difference....?
