Here's a guestion for all you guys that have added bigger turbos and better injuectors and fuel systems. Have these mods helped you fuel milage in any way.
Thanks

only if i can keep my foot out of it.

some of the aftermarket injectors have produced some improvements in economy. the bigger turbos need more fuel to spool, so generally it goes down.

in my case i lost about 1 mpg after installing the bigger hairdryer.

 

I was wondering about that. I have already installed guages and a box and exhaust and I have been thinking about what else to do to get some more millage.(Already planning the intake) So I was just wondering. I've heard that injectors help. Also I heard that trying a boost fooler might be good. I'm kinda wondering about the boost fooler becasue right now I can hit 44psi and I thought 45 was about the most you wanted on a stock trubo.
Thanks
Jimmy

 

20k miles of 44 psi on my stock turbo. When i upgraded it, I just happened to look at the original, there is alot of shaft movement, both axially and radially. It was pretty close to commiting suicide.

 

The stock turbo is out of its effiecency range long before 44PSI. With my truck putting my twins on along with the fuel system and all the other mods in my signiture did help my fuel millage a little bit...if i keep out of it. But the cost of all these will probably never be canceled out by fuel savings...

 

i changed my turbo out only for egt reduction. which it did big time. i didnt do it for mileage or power increase. Just the ability to use the power I have without having to either back out of the pedal or risk engine damage from the excessive egt.

 

Thanks guys. I hardly ever hit 44 usually run around 25-30psi. Thats just the max I've seen. I just use a fuel millage increase to justify the power toys if you know what I mean!!!:

 

you can tell her whatever you like about the economy savings to justify your mods.

seriously though. even my wife has noticed the improved economy from stock until now. Last summer we went to cour d alene idaho to the water park. halfway across washington(moses lake) we were on fumes and had to refuel. we were stock except for the pacbrake.

This summer same trip, same trailer made it to cour d alene and then got fuel. she doesnt notice mpg, she sees how often i have to spend $100 to fill up. she commented and asked why we went so much further. I told her all the mods.

 

Cool thanks. My wife is pretty understanding she let's me get away with just about anything as long as we have the money.

 

mine has not been too understanding as of late. maybe the tires, wheels, and turbo i bought on 1 day. followed with the south bend. wait until she finds out i am ordering my smarty this week.

 

After having all those mods the smile on your face will compensate the money you lose in fuel economy.... It's worth it!

 

About how much is a good turbo. New injectors, fuel system. Also what is an upgraded tranny running. I'm pretty sure I don't really want to know but hey I'm interested!!

 

Now I'm jealous My wife was furious when I drove into the driveway with the new truck... I didn't tell her about the Quad Xzillaraider I bought that day too.

 

Dyno just let here drive it a couple of times and I bet she'll be smilin after!

 

She doesn't know how to drive a stick, and she's afraid to learn. I told her that it's easy in this truck, but she still doesn't want to try.

She's getting over it now, I bought it in July, and she's getting her revenge by spending a lot for Christmas.
