Volant CAI, Underdrive pulley, 4.10 gear(how hard to install)

How much more would i see mpg? I dont know if im gonna keep my 31's on yet or just get regular 16" all terrain tires. Any suggestions

 

your gonna spend more than you will ever save.

 

I drive about 90 miles a day and have to fill up every four days so i spend about 80 bucks a week on gas which kills me. Anything will help. Gears on ebay are 100 bucks, The intake im getting for 85 on here from a member and the pulley i just bid on one on ebay with a belt for 15 bucks. So thats like 200 bucks

 

Don't do it..

it not like your going to get 30 MPG...

 

if your going from 3.73 or another gear around that to the 4.10s you will hate them on the highway. Flat out 4.10s suck costing at freeway speeds... Around town they may be better(less throttle to get up to 40 or w/e) but yeah i wish i had 3.73s on the freeway....

 

scratch the gears then im still buying the 4.10's for the stang but back to the topic.....What can i do to increase my mpg....

 

Electric fan. Exhaust, intake, and best of all, stay off the thottle! But you're mostly chasing a ghost...

 

im not looking for 30mpg... If i can reach 18mpg instead of the 14 im getting ill be happy

 

Put in an Air Conditioning Compressor Switch found in How To's. I turn mine off on the highway. KandN replacement filter if you dont have one. The best thing is just to keep top speed as low as possible like around 60. I also put my tailgate down on the highway but some will say not to. It seems to me that the truck runs better after I spray out the radiator when I wash the truck too. Maybe even run a bottle of fuel system cleaner through when you do oil changes. Ive also heard that Royal Purple 5-30 synthetic oil helps in mpg's but I dont know.

 

i dont think the intake is gonna help. get your stock tires back on it. keep the gears you have, efan, dont run the a/c, or defrost, keep the windows up, get a tuner from doug. maybe underdrive pullies and a magnaflow exhaust

 

i would say, stock tires, throttle body spacer, air intake would be nice but i dont think it will help the mpg, ac used gas so that will hurt you, opening windows causes drag so that will hurt gas,

will a baja net in the back make for better mileage(the legend of better mileage with the tailgate down????)

 

Although it may be counterintuitive to most people, it has been proven that lowering the tailgate increases fuel consumption. The faster you go, the greater the effect.



From best to worst for highway MPG:

Hard tonneau, gate up (best)

Soft tonneau, gate up

Open bed, gate up

Open bed, gate down

Tailgate removed

Tailgate removed, Baja net / air gate (worst)




Constant speed highway fuel economy can be improved with a hard tonneau but any gains in the city would be offset by repeatedly accelerating the added mass.

At first glance, the tailgate appears to be a sail on the back of the truck. In actuality, the tailgate reduces turbulent flow by creating a semi-trapped air pocket that smooths the airflow and reduces the coefficient of drag. Dropping the gate destroys the bubble, increases turbulent flow and exposes the rear of the cab as a very large trailing surface compared to the smaller surface of the tailgate.

Bottom Line:
A pickup truck is still poor aerodynamically compared to most cars but driving with the tailgate up helps. Lots of info on this. Here are a couple of the many sources you can find with Google:

4.10's on a mostly stock fox. Good luck with that. Dont try and launch too hard.

 

A hard cover got me about 2-3 more mph, but larger tires killed that. Even going from the stock steel XLT wheels and tires to the Edge plus ones really did a number on my MPG. That rotating mass will kill ya.

 

A hard tonneau might be good, I've got a soft one, and by my calcualations it'd take me 100,000 miles with it on just to make up the cost I paid for it ($200)

 

This was on Mythbusters too once. Keeping the tailgate up DOES decrease fuel consumption vs. tailgate down. It also keeps you from backing into **** and bashing your tailgate up

 

^^a friend of mine told me about myth busters trying that but i want sure, but the tailgate removed is great for plowing to see behind you

 

I'm almost there then. Less than 10,000 miles to go. Good info.

 

an intake wont help at all. do the efan, go wtih smaller tires, maybe get a tuner. there isnt really much else out there that REALLY helps your gas mileage, other than staying light on the pedal, all the time

 

Ive also heard that Royal Purple 5-30 synthetic oil helps in mpg's but I dont know.

Royal purple synthetic oils are usually recommended for turbo'd 4 cylinders.

 

Dont forget- a bunch of stickers, especially NOS ones, improve horse power!!!!
LOL!
Yeah Im about to put in some Royal Purple so Ill try to post some info when I get it in.

 

I think most everything has been said but

AC mod switch gives me about 1 MPG in winter(well all weather that you don't need A/C)

I think my soft bed cover was worth 1 MPG

Those are the only things I have done that helped me.

Things I have not tried but would bet on : E-fan, underdrive pulley, smaller gears like 3.55's

 

If you want better MPG and you do a lot of driving, face reality.....get a small car. LOL
A truck is crap-tastic on MPG anyway.

 

NOt at all Toyota is the smartest Their tacomas get better mpg than our rangers and their bigger and more powerful
