Debating on where to put this post. It is about both. I'm making this post more to say/show that you can have good performance and still have great gas mileage. This is about my car 2001 Z24. Mods are in my registry (pretty much every bolt on N/A mod). My car has always gotten pretty good gas mileage with the mods I have. I lot of it has to do with how you drive the car. I use to get about 300 in city driving, and close to 400 on the highway. Usually around 30 mpg. Have gotten 34mpg on a highway trip. I now have HPT and got my own wideband for tuning. My car was running super rich!!! 11.5's. Leaned that out (shooting for 13.0), currently at 12.6-12.8. Since these changes my gas mileage has went up!!!! I have not got a chance to figure it out as for MPG's. I filled up for the first time 2 weeks ago. Did a lot of city driving, and then made a 100 mile road trip. at half a tank I had 279 miles. At halfway between 1/2 and half a tank I was around 330miles to the tank. Once I got to where I was going it was city driving and I let someone else drive my car (who does not get to play with a manual car much). We were beating on it. When gas was needed it was 399.8. I truly feel with a complete road trip it will hit 500 miles to a tank. Worse case it will get 450. I just wanted to show that you can have a good performance car and still have good gas mileage. I also have found that shifting around 3500 RPM's works better than shifting at 3000RPM's. Mainly because it keeps the RPMS up enough to not put much load on it in the next gear.
FU Tuning
That's awesome. I've been watching my injector pulsewidth as I drive, and if I shift when my indicator light comes on, the pulsewidth goes up. Meaning, it's burning more fuel. Shifting around 3k rpm seems optimal so the pulsewidth and fuel consumption goes down. Also, driving a few mph slower on the interstate seems to help it too.
My mods are in my profile.
By making the engine more efficient you are making more power, and moving the same weight. As long as your not on the gas more than you should be. My z24 was getting about 33-34 mpg on average, but when I beat on it ALL the time I got about 15-17mpg.
Makes perfect sense to me.
