hey dudes how are you, first happy xmax, jejeje look i know this questions is very common but well, do you think the intakes affect the gas economic of the car? i know if i drive like a fast and the furios my gas will be in 2 racing....jejejej but if i drive normal, etc etc...it will be a difference if i use my intake(midpipe, maf, k&n filter) or the stock air box???

 

Intake=cool sounding engine at full throttle

so it makes you waste more gas because you floor it more...

 

Supposedly, a good intake helps your engine breath (a good exhaust also contributes to this), in order to help maximize output.

But once you start getting addicted to the cool sound of the intake/exhaust(and the mod bug), you develop a lead foot and there goes your fuel economy.

 

I can contest to that. I do nothing but give it WOT 90% of the time. Gotta love it thought.

 

Max 002 hit the nail right on the dome piece

 

In theory making your car faster NA should help fuel economy. But as everyone else says, with a lead foot you won't see better fuel economy.

 

hey blaxima is that a grand national next to that pic of the max?

 

Actually its my friends 88 Monte Carlo SS, same car basically.

 

as stated earlier N/A mods are supposed to make your car more efficient, and as a byproduct better fuel economy.

however the realization of more hp causes severe lead foot. i have to make an effort to go easy on the car so i can get some decent milage. , more than 240/tank-city.

 

same here lol,

 

Well, if you are a granny driver, you might get the EPA mileage on your max. But chances are if you add an intake, you drive like what Tom and Ray (Cartalk) call a "wacko" so you will be leadfooting it, killing your gas mileage.

Hehe...count me as one of the wackos. I try to get good fuel economy, but the go pedal is just too much fun to press.

 

i drove from seaside heights NJ to poughkeepsie ny (home) with my intake and exhaust. It was about a 140 mile drive i think. i kept it in the 3-3500 rpm range at like 90 mph all the way down the garden state pkwy and I-87. i checked the milage when i got home and i got 44 MPG/avg. it was a nice cool day out not humid and there was no traffic so it was constant driving. i don' think an intake makes much difference. i think it's the lead foot factor. my highway driving MPG is probably double my city driving

 

Wow 44mpg. My guess is that the gas pump didn't fill your tank all the way. Its hard to guage how much gas you use up when you use up so little of it. Better to take it down to half tank to make sure you minimize the variances of the pump stopping a little to early or a little too late.

One time I drove 60 miles and filled up a little over two gallons. I went woohoo!! Almost 30mpg. But then I realized it was due more to the fact that the less you fill up, the more inaccurate the mpg calculation is.

 

I get better gas mileage on the highway with my intake when I keep it at 75 or under 80. In the city, my gas mileages is lower than in stock form.

 

ya, i hab the same thing since i've put mah intake in
