Injen = bad mileage?

[~Spadwaller~]

I recently got my injen SRI installed and I think that my car is using up more gasoline is this possible or is it all in my head?

[ThatVietGuy]

I just got mine in and just got a full tank. I know I'm gonna get a really bad MPG because I've been flooring it every chance I get

[PhreakdOut]

In theory, more air in, more fuel needed = more power.

You can't have your cake and eat it too. (What the heck does that crappy saying mean anyway?)

You get the idea. Stop your whining and start enjoying how tough your Solara sounds. Just kidding bro!

Just take it easy on the throttle and you'll be fine.

actually, adding aftermarket intake will get you better gas milage and more horsepower at the same time. All that restriction with the stock intake system kills power.

it is best to do a complete intake/exhaust system rather than just having the intake and leaving the stock exhaust in place.

installing Intake (or performance air filther), headers, and cat back exhaust will make a noticeable difference in performance.

hope this helps

maybe its your s/c

I haven't had a problem with mine since I've had it, and it's been about 4 years now. I also have the Greddy EVO II and wouldn't expect to be conserving as much gas as I use to where it was bone stock.

[99V6solaraSE]

yea i would think that since itd run more efficiently that itd be more gas efficient... but then again maybe im wrong..

[LatinDragonXJC]

I think, because of the new intake, driving habits change, and you begin to floor it every chance you get.

I disagree.

More air movent is beneficial if you want hp/trq gains, TRUE.

However the more power, the more gas is used.

The best gas efficiency you can get, is to remain stock and do basic maintenance.

Think about this, most stock intake/exhaust system are restrictive. The more restrictive it is, the more effort the engine has to put in order to make it work. You put in a less restrictive system, there will be less mechanical inertia therefore more gas is saved and more power is produced.

Think about it this way. The less restriction you have on the intake, the more air you can get in. The more air you can get in, the more fuel you need to use to maintain the same air/fuel ratio.

Fuel is not spent overcoming the intake restriction, that is the intake stroke on the piston, which is a continuation of the exhaust stroke after combustion. Fuel is used to mix with the air at a certain ratio to combust once it hits the cylinders.

[NeFaRiOuS_SLE]

It's almost a weird balancing system... Usually a clogged air filter would rob your gas milage, but it's weird of how I actually noticed better milage after I got my K&N's, and the stock filter was squeaky clean (at the time I thought a drop-in K&N was just as good as an Injen).

[Turbosolara]

I heared therotically since the car runs more efficiecy, it should save more gas. but i blieve this only if you do lot of freeway driving. Since you lost low end torque, it will cost you more power to pick it up in stop and go situation.

have you reset the ecu properly? (10 mintues disconnection waiting and 10 mintues idle)

is your right foot become heavier?

I'm putting the stock back on and only using the injen for dyno-tunes and meets

Thats what i did on my celica. My personal exp with intakes is that they rob you of mpg's, but the power gains are there (minimal...)...but the sound gains are 'SURELY' there.
