why doing it for MPGs your spending money and will never make your investment back
i find that very hard to believe that you will double your MPGs also did you do the math on running 91+ gad because turbos need the extra octaneWell if I double my MPGs like the vq motors do, then I would only have to burn through 50 tanks to get my money back.
I did my math at $2.99 a gallon, which is about average where in live for 91.i find that very hard to believe that you will double your MPGs also did you do the math on running 91+ gad because turbos need the extra octane
if your parents are barely getting 16 on the highway then they must be driving with the overdrive off or something. i'm guessing you mean as their average they barely get 16 which you have to factor in alot there, like how much highway and city that is, how much weight they tend to have inside (how many people) your general weather, and driving habits. there are many many people that get over 20 on the highway in their vq40s so you really can't go so far as to say its doubled, and have you though about city driving. the fuel mileage benefits really depend on you staying out of boost. my twin turbo z could manage almost 30 on highway trips (not much over stock mpg of 26 highway) but in the city i generally got in the area of 13. i think my average with driving 50 miles a day (25 to work 25 home) being highway was still only 18Xterrahines gets 30 on the highway. And my parents stock xterra barely gets 16, and I'm sitting at 17.

even with little start and stop those hills aren't going to do you much good when it comes to MPGs on a turbo charged vehicle especially one with the weight of our trucks, your tires, and how little torque the motor itself produces without the assistance of boost will force you into a generous throttle pos when going up hill and you'll most likely see boost of a couple psi quite often in your drive. i really don't think your going to get the result that your wanting, it would be a very cool project none the less. gears would make it easier for your engine to turn those tires by transferring more of your torque to them so you'd be able to be lighter on the throttle to get yourself through the lower gearsThe average is 16, with daily drives going 45-65 average speed. Very little start and stop. I live out in the hills of northern ca.
