sol740 Posted July 15, 2008 Report Share Posted July 15, 2008 ^ thats the trick right there ... My friend says his STI averages around mid 20's without the lead foot. Quote Link to comment Share on other sites More sharing options...
phil Posted July 15, 2008 Report Share Posted July 15, 2008 I just talked to mike about that today. he's got a few mods and bigger injectors and said he gets around 20ish Quote Link to comment Share on other sites More sharing options...
SpaceGhost Posted July 15, 2008 Report Share Posted July 15, 2008 I have never seen 22mpg on a tank, I'll post proof, I would love to see some documentation for an STI getting 24-25mpg especially with 1000cc injectors. I have High Flow cated DownPipe (Cobb) Axel back exhaust (Prodrive oval tip) Dyno Tune @ Buschur by Tim Bailey of PDX Racing out of Oregon.

sol740 Posted July 15, 2008 Report Share Posted July 15, 2008 ^ my buddies is stock and he drives like a grandma. That said I don't have any real proof he gets that, he just said he did. Quote Link to comment Share on other sites More sharing options...
SpaceGhost Posted July 15, 2008 Report Share Posted July 15, 2008 I drive like a grandma all the time, 25MPH in 4th and all that, you can see when I don't, the 18MPG says it all. The best I have had is 21.65. I have a brand new air filter, and Mobile1 syn oil 0w30 for better fuel economy. Tires are checked and inflated properly every week. As you can see I purchase Shell 93. Started in Mid march recording my stuff, in the beginning, all I had was receipts, so no milage but for the last few months I have proof. I don't think I can give you any more real world info....... I have spent almost 1k on gas since March. And I normally am getting under 300 miles per tank. A couple times I got over 300. I drive mostly highway except for the 5-6 mile drive from Day Care in Westerville to my house in Westerville only 3 times a week. I bought the car in August of 04, so 50K is pretty low Milage. http://www.columbusdiscgolf.com/IMAGES/Fuel_Log_Book.jpg Quote Link to comment Share on other sites More sharing options...

Dyno Tune @ Buschur by Tim Bailey of PDX Racing out of Oregon. Posted above..... Surely I am not putting down 300HP without a tune on IPS's DynoJet. http://www.columbusdiscgolf.com/IMAGES/IPSdyno.jpg Here is at Buschur 93 octane http://www.columbusdiscgolf.com/DynoVids/PumpgasDynosheet.jpg Here is buschur 100 octane http://www.columbusdiscgolf.com/DynoVids/GT100Dynosheet.jpg Quote Link to comment Share on other sites More sharing options...
Buck531 Posted July 15, 2008 Report Share Posted July 15, 2008 You're not getting that kind of mileage racing Honda S2000's though . Quote Link to comment Share on other sites More sharing options...
Dr. Apex Posted July 15, 2008 Report Share Posted July 15, 2008 I know Ray only gets in the real low 20's in hs 2.5i, which is pretty pathetic if you ask me. Quote Link to comment Share on other sites More sharing options...
Rookie84 Posted July 15, 2008 Report Share Posted July 15, 2008 I used to get low 20s with 850cc injectors and GT30R. I have a heavy lead foot. Quote Link to comment Share on other sites More sharing options...
Buteo Posted July 15, 2008 Report Share Posted July 15, 2008 im probably mid 20s, but im driving a 2.0l wrx. Quote Link to comment Share on other sites More sharing options...
Draco-REX Posted July 16, 2008 Report Share Posted July 16, 2008 I'm just Stage 1 tuned. My city average is about 19-20. I'm going Stage 2+ soon, I'm told my mileage should improve (once I get over playing with all the new power. ). The best economy mod you can do to the car is a boost gauge if it doesn't already have one. Keep it in vacuum and you'll get good mileage.

The best economy mod you can do to the car is a boost gauge if it doesn't already have one. Keep it in vacuum and you'll get good mileage. this isnt exactly true either. you want to keep it in vacuum but with pedal to the metal. This keeps the fuel being totally used for energy. so hit the gas hard and shift early. You dont want to creep up the rpm's pulling 0 boost b/c then the fuel doesn't totally get burnt. Do some research on hyper-miling and you'll read what im talking about. saying all that junk, i got around 17-25 in a regular 2.0l wrx. its that all wheel drive that kills you. new plugs, diff oil, clean air filter and free-er exhaust had no effect on fuel milage for me...it just chewed up gas!

SpaceGhost Posted July 16, 2008 Report Share Posted July 16, 2008 You're not getting that kind of mileage racing Honda S2000's though . we will see with the next fill up. My guess is 18MPG. Quote Link to comment Share on other sites More sharing options...
trbmiata Posted July 16, 2008 Report Share Posted July 16, 2008 my guess is that the new models 07-08 will get more considering there ecus have such a lean tune on them. Most people I talk to that own sti's say right about 20. Quote Link to comment Share on other sites More sharing options...
Nitrousbird Posted July 16, 2008 Report Share Posted July 16, 2008 its that all wheel drive that kills you. Then why do the Audi A4 2.0T Quattros get such good mileage? Even modded like Jones's...hell, his gets better mileage than stock putting down numbers approaching 300 to the wheels w/ a downpipe and tune.

silverhatch Posted July 16, 2008 Report Share Posted July 16, 2008 I average between 20-22 mpg. I drive like an old lady most of the time and daily mostly highway commute 20 miles each way. Last summer when traveling on interstate for vacation we averaged 25 mpg. on a few tanks which I thought was pretty decent. Mods: I have aftermarket exhaust and recently bought a Cobb tuner. I haven't noticed alot of difference in mpg. since buying the Cobb though. Quote Link to comment Share on other sites More sharing options...

dragknee66 Posted July 16, 2008 Report Share Posted July 16, 2008 When my 5.7L gets almost the same damn milage as a 2.5L and a 2.0L does... thats sad Im sorry. Quote Link to comment Share on other sites More sharing options...
Orion Posted July 16, 2008 Report Share Posted July 16, 2008 hyper-miling thats gotta be the gayest "new green economy" term of them all. Quote Link to comment Share on other sites More sharing options...
2highpsi Posted July 16, 2008 Report Share Posted July 16, 2008 my guess is that the new models 07-08 will get more considering there ecus have such a lean tune on them. Most people I talk to that own sti's say right about 20. The leaner tune is mainly during spoolup. It will help a little, but if you are driving easy enough to stay in closed loop anyways then it won't. Closed loop idle and low load will still target 14.7 because of emissions.
