What Kind of MPG to Expect
Hey guys. Im looking to upgrade the ol PSD in the very near future. Some upgrades Im thinking about doing are some Rosewood Stage II (or possibly III) injectors, upgrade to a D66 turbo, put a 99-03 intake on it (supposedly better) along with my 6637, some sort of tuner (liking Riffraffs) maybe some up-pipes and hook it all up to my 3" DP to 4" exhaust (of course the trannys next)
I don't think this stuff is too radical but Id still like to stay somewhere in the neighborhood of 16+ mpgs. The only thing that scared me was my brother drove a Cummins pulling truck as his DD. Huge injectors, massive turbo, etc etc and he claimed 11 mpgs... That's ridiculous! A 460 can do better than that! (At half the power) |
Your mileage won't change much with upgrades, unless you can't keep your foot out of it.
|
I get 12 with my truck. But it is heavier than stock.
|
I'm getting 15/16 mixed use average with my mods in my sig.
A couple of things about the mods you listed. What are your HP goals? Stage 2's and definitely 3's are a bad idea for the D66. It flat out can't keep up. Do you tow? What do you want out of your truck and we can point you in the right direction. |
Ahh someone asking the right questions lol. Im kinda shooting in the dark on this whole deal.
Here we go: This will be mostly a DD. I have a slide-in camper (one that slides in the back of the truck) that I use occasionally. My father-in-law has a race car that I offer to tow for him a few times a year. And mostly, I want something that is completely reliable but has a good kick in the pants! I have no desire to race or take it to the pulls whatsoever. If I got 400 hp, I would be blown away. That's plenty for what I want I notice your sig says stage IIs but no turbo upgrade? Can our stockers handle stage IIs? |

Every truck is different too, My ole girl loves 2-stroke

Im going to take a different approach after chatting with Mike (aka fordpride)
Stage I Injectors S366 Good Tuner Intercooler Head Studs Springs and Pushrods And of course... do something with the tranny I may try to stick with my stock turbo for now unless its going to be a huge PITA to put in while the engines in the truck. Then it may be worth the extra $1200+ lol And also, Iv heard of E-Fuel mentioned a few times. What is that? |

So is it just an electric fuel pump or is it a whole fuel system upgrade?
|
It's a whole system upgrade, and is necessary if you do the S366. The turbo uses the plunger hole in the block for the oil return.
Why are we discussing a build in two threads?? |
They both kind of got out of hand lol. If it helps, each is teaching me something different lol. I think Ill just start a build thread and go from there lol
|
Hey guys. I have 2 nearly identical threads going on right now so I decided to start a build thread! We can continue this conversation over there. I want to say thanks to everyone who has responded!!
