modding for increased fuel economy?

[Kookykrispy]

yessir, I'd like to know what I can do to increase my fuel economy.

I already have a K&N filter, UICP, Apex BOV, 3" tanabe catback, soon to be a 3" turboback when I get my hi-flow cat.

What else can be done to increase mpg?

Nobody did any thing wrong for starting or participating in this thread. Go away if you dont like it.

Also, when did I or anyone say that you did anything wrong? We said if you can't handle the extra gas consumption that comes with modding, well then your pretty much stuck. Never said that you broke a rule.

i am not battling any thing. Where do You get off telling me I am battling?


As far as performance goes, I think this fits firmly into it, and has nothing to do with loud blow off valves. How could you even confuse the 2. By increasing the efficiency of air flow, and ve to effectivly produce more power consuming less gas sounds like a performance aspect to me. Why dont you go tell interior and exterior mods forum to kick rocks, this is a performance site, or the hang out, or the entire community section by your logics. How about the next guy that has a reliability question, tell them who cares as long as it's fast right?




What ever, and enough off topic BS, unless you would like to help some fellow dsmer's out with some questions here, go massage your ego some where else, slim.

You're right, Hissy Fit would better describe what you are doing

You threw out a bunch of rules that didn't relate to anything that was said. I threw one out there as well.

look at 99% of my posts. Does it look like I have some kinda ego? I kindly help everyone out. That is until some pup tries to call me out by saying stuff like "Who are you to say I was battling". Got me there ya sure did. Ouch. Anyway, go find some real numbers showing the improved gas milage. I know with every mod I've ever done, my driving habits became a little more aggresive because the car becomes more fun to drive. That alone is going to kill your milage. If you don't drive a lil harder after doing mods, well then maybe, just maybe, you'll see a couple mpg increase. You could save that same amount of money by skipping lunch once every 2 weeks.

The max pressure listed for my tires (on a different car) was 51 psi, so I put about 45 in them (up from the 35 I was running) and noticed about a 1 MPG difference. For naturally aspirated engines reducing the parasitic losses (pumping losses) by opening up the intake and exhaust can yield noticable differences, but the blower motors aren't as simple. You might get better mileage if you rig the wastegate open all the time, but what fun is that??

just smile and wave, uh huh! just smile and wave

No. Opening the exhaust up more will reduce the velocity and force the engine to work harder to achieve the same power. At low RPM, the last thing you want is a super-free-flowing exhaust.

40 minutes after you posted this, you edited it and that's what you came up with? Let's just stop this now. You win OK? My ego has been crushed cuz I'm the one that has one right? I'm sure you'll attempt to make another crack at me, which is fine because you win bud, enjoy yourself. To the guy who started this post, sorry for all this nonsense. Just make sure your car is in tip top shape maintenance wise, and watch your driving habits. Hopefully you aren't trying to reach for 30mpg because it prolly won't happen. The best milage I've ever gotten on my talon was 26, and that was pure freeway driving, windows up, no a/c on, from Arizona to Minnesota. Around the city, I average around 20 because I normally have windows down, and i usually drive fairly spirited. Windows closed made about a 1 mpg difference on my trip. Don't expect civic type numbers. Good luck in your voyage!!

What are you talking about?

Well, I wasn't talking to you, but I'll play.

Do you race your car every where you go or some thing,

Um.... yes, I pretty much do.

is that why you dont care about milage?

Where did I not care about mileage? What

Well i grew out of that stage around 18 and drive like a civil citizen 99 percent of the time (accept after 1 am) so i wouldn't mind having some decent fuel milage.

Goodie. I always drive civilly, I just drive real fast.

Seems like ive seen you all too much chiming in to say some thing negative about how you dont like a topic, opinion, or thread.

So make my posts invisible to you. Won't matter to me any.

What gives defiant?

What "gives" is that every third post is somone with a non-turbo wanting a turbo, or an FWD wanting AWD, or someone who's bought X finding out they want Y. And now we have someone with turbo/AWD wanting mileage. It won't much be happening in something with the performance output of the turbo/AWD DSM. With luck, cruise control and flat roads, you might get 23mpg. Hardly a winner in the Mobilgas Economy Run. And modifications aren't going to do anything about the DSM's extra half-ton of weight.

C an't we all just get along?

Sure, suits me. What did you sit on?

What if you bought a manual boost controller, and a boost guage. For well under 100 bucks I think you would have the biggest possible effect. Normal driving, highway driving, long trips you could turn your boost way down. Less air, less power, less fuel. When you hit the rocky mountains, or want to get on it a little bit take it back up to stock, or a smidge above and take advantage of those other mods.
I dont understand where this thread went wrong, it seemed to me like defiant made a decent sugestion one rout to better mileage and then it turned into some crazy non dsm related :laugh: . Hopefully it's all resolved now though

 

[clownface]

Under normal driving conditions your hardly even in the boost anyway....or at least thats the way i drive usually, light to light or interstate. On the stock fuel system, unless you drive like a mad man, i dont think turning up the boost is gonna lower your mpg to much cause if your like me your only in the boost for short periods of time no matter if its 10 or 15 psi.

Im not 100% sure on this one but i dont think you can turn the boost lower then what the wastegate is set for and that would be like 10 psi or something.....unless you disconected the waste gate then you can only boost like 1 or 2 psi.

You can't turn it down less than stock.

It really all boils down to what is more important. If MPG is one of the more important things then maybe you need to look into some other cars. Having a turbo car isn't really for people who are worried about MPG. There is really no way to have your cake and eat it too in this situation, science won't allow it (yet).

Well considering wrx has no problem seeing 25mpg, as well as lancer evo wich well over powers the mitsubihi eclipe, along with other member on this very site who are getting considerably better milage than myself, I have taken an interest in getting better milage, atleast until I am on par with every one else. To say that some thing can't be done and is not teknologically possible yet is pretty humerous at best.


I think I am done with this one.................

 

[14.5 drift]

errr,... just.....can't......resist



YOUR MOM!!!







Whew, okay, now I 'm done.

 

[DSMX921]

Better, swap the car you don't want with an N/T owner for the car he doesn't want. Then everybody'll be happy.

im down to trade

 

[psychlow]

Probably the best mods you could do would be an electronic boost controller, an SAFCII, and an external wastegate.

You could run 0-5PSI when you want good gas mileage on one fuel map tuned to lean it out (it's pretty rich from the factory), and when you want to get into it, change fuel maps and run 15PSI.

Well until your car turns into a WRX or Lancer EVO then you may have to accept the fact that it's an eclipse > a car that has probably never been on any "fuel friendly" list. So if your money is that tight you may need to go browse the toyota prius forums. And until you can show and prove it can be done then what i said still stands "You can't have your cake and eat it too". So if it can be done w/o sacrafice WITH THE CAR THAT WE ARE TALKING ABOUT ...then you should do it.

 

[14.5 drift]

I think I am hearing you, I will guage my mods and mpg to see if one has any effect. Will post my personal results later in the next few years, .

 

[jdurston]

Would raising the compression increase MPG because of increased thermodynamic efficency?
Not very cost effective though. But it would give you more bottom end torque and maybe you could be happy with less boost.

 

[psychlow]

Thought of another one....

Removing the balance shafts. Also, remove the A/C and power steering if you don't need them for some reason. Purchase lighter wheel/tire combos.
