went from 18 to 26 mpg with nissan pickup
 

hey im Brent i have a 97 nissan pickup with 300,000 miles on it :) when i got it i was getting 18 mpg!
here is a list of mods i have done to get me to 26 mpg in town! that is a 44.4 Percent Increase
oh and by the way there cheap mods!
------------you don't need to spend a lot for better mpg-------------------

free mods Ive done

mug flap delete

i turned in my side mirrors

i taped up some vents for the ac system there on the top of the hood

i had a rubber matt in the back and i took it out it was huge every bit of 50 lbs it was 1/2 thick


tail gate delete


pay mods

i went from 225/75/14 tires to 205/75/14 tires
80 each but needed tires any way

i have a k&n air filter but it came with the truck ;) but i had to buy cleaning kit 12 bucks

i shorted the intake on my truck and used 2inch pvc pipe and i drilled 4 holes in the intake
free i had the stuff laying around but if i had to pay for it it would be like 10 bucks

any ideas? im not thinking off?

Welcome to the forum.

FYI, the tailgate delete may be hurting your mileage.

Anyone with a pickup should study this chart:

http://ecomodder.com/forum/attachmen...1&d=1334841255

I hope you adjust odometer reading when you calculate the MPG.
there's fairly large difference in circumferences between two sizes. about 4.5%

If you didn't you still got about 25mpg. Since your tires are about 4.3% off, next time you fill up multiply your mileage by .957 like this; because your new tires are 95.7% the diameter as your old set.

260miles/10gallons=26mpg. - wrong
260miles*.957=252.2. 252.2/10gallons=25.2mpg

Although, if the old tires on the truck aren't the original size, find the original size and google search a tire size calculator to find out the percentage they're off. I have to do the same thing with my ford ranger except backwards cuz I put taller tires on to bring the rpm's lower while cruising.

cool math!!!! but i know how may miles i have gone because of my gps

nice chart but the mythbusters test say i will get better mpg with out my tail gate

Before you buy a new electric fan look at junkyards. Most FWD cars have them, and that is what most cars have been for the last 30 years. You should be able to get one close in size for $20.

test it your self
 

thats the only way to know for sure i dont have a scan tool

you know what i will do that :) thank you

I would say: skip the tailgate stuff and proceed directly to more effective bed solutions.

Tailgate effects are also dependent on cab & box design - especially respective length of each - something Mythbusters probably didn't mention.

SAE has also studied this and concluded differently from Mythbusters. I wonder who does better science...

The KA series of engines are awesome...keep the numbers coming and get yourself an ultragauge or scanguage. Well worth it!

they are!!!!!!!! mine has 300,000 miles on it!!! every one always talks highly of them! and i never get sick of hearing it!!!!

and ya a scanguage would rock lol

true true :) and know they didnt and for the test they where useing a 2000ish ford f-150 my bed is smaller then that (5ft w 6ft L) i really didnt think of that so thank you:D:D:D:D:D:D

That's a moot point if you bend up about 6 sticks of EMT tubing, and skin it with something. an aeroshell kicks butt :)

The best electric fan IMO is from a 90's taurus. I have one in my ranger they come with a shroud attached and are 2 speeds so if you off road you can wire up high speed to a switch for when your stuck in the mud and spinning your tires.

As far as tailgate removal, it definitely varies model to model. My ranger gets about 2 mpg better without the tailgate but my 2011 Tacoma gets about a little less than 1mpg worse. Also, one of the best aero mods IMO that you can do to a truck is an underbelly tray. Cars, generally speaking, are mostly flat underneath due to there uni-body construction whereas trucks have a full frame so the floor pans are atleast 6 inches above the frame and the beds are even farther up while the axles, exhaust, spare tire, cross members, drivetrain, etc. hang down all producing drag. When I put my ranger back on the road it's one of the first things I'm going to do to it plus depending on what material you use they can be free or close to it

what air pressure are you running in your tires? I have a 95 nissan 4x4 pickup and I get 26 mpg with 50 psi in tires. no other mods except coasting when possible.

in the front 44 psi max side wall in the back i have trailer tires 50 psi max side wall all 205/75/14's
