iv been trying to get the best mpgs i can. just did the hub convertion, now looking at injectors and some trany work. i was thinking of getting a triple disk converter, new valve bady (any sudjestions on brands) and f1 mach 1.6 injectors. i tow and haul alot so i have to worry about egts. sudjestions? ideas?

I think driving habbits will help alot and tire choice.

Have you noticed any change with the hub converion?

If you don't do any towing, pull the fan, clutch, and shroud off. Change to Evans NPG coolant so if/when you are stuck going slow for 20 minutes non-stop in 100F weather, the resulting 230F coolant temps won't hurt a thing.

Been running fanless for almost a year now and never had a problem. Picked up 2-3MPG, was a big change.

theres also the electric fan kit from flexalite. I'd like to try one out on my truck, but they are super expensive.

so was the hub kit, and so far iv seen about 2 mpg difference, im hopeing that holds true. i do alot of towing and hauling, i have about 5000lbs in the bed of my truck as we speek. anyone know a price on the electric fans?

bullboy85

anyone elce done anything thats made a big difference on mpgs? got any little easy things to try? feedback on the injectors and trany work idea?

I think the electric fans are not that expensive:
It looks like it's $550 from Jeg's here.

Here's my recipe for maximum mpg:
1) M1 or 1.6 injectors.
2) Quad XZT+ module
3) 235/85r16 tires at high pressure
4) tonneau cover
5) free-spin hubs
6) Tight 91% DTT converter in a DTT trans
7) Synthetic lubes in all gearboxes and differentials.
8) Larger turbine housing on stock turbo
9) 4" exhaust
10) Helix 2 cam
11) FASS or Airdog fuel system


Obviously, most of these mods will never pay for themselves, but I think the freespin hubs and electric fans have a good chance of paying for themselves reasonably soon.

How ard was it to install the hub kit if you did it, How much was it, and could you give me a link please?

I picked up about 1-2 mpg going from stock injectors to a set of DD Super Mentals(140hp). I have since lost that 1-2mpg buy going to M6's and then M7's I still get 17-18 most of the time.

sounds like ur the guy i want to bounce some things off of then. im not going to do the tires cuz i want the truck to look good, im going to end up with some 33s on it but i figer that shouldnt set me back to far as long as i drive it right and do everything elce practical to get my mpgs up. i need to chang all my geabox oil, any better brand to go with? have a flat bed so no tonneau, u say larger turbine houseing on stock turbo? wont that slow my spool up a little? or would the injectors counter that? any good housing i should be looking at? i know ill have more questions after i do some research

bullboy85

i spent about $1500 after all said and done, theres 2 threads talking about just them. one i started called hub convertion. it has a link and a bunch of info from a few of us that did it. now i had to do the cad delete too u might not have to or want to do it. it was really pritty easy. not any harder then changing barings on the same type of set up. all in all i needed new barings and rotors this kit came with everything. so i might of still made it out ahead. ill go get that link and post it here too

ok i do have another question, i have horses so am i going to need the livestock valve body or will the towing be ok? can i get the tc and vb first and get the bult up trans later?

RAM2940

I think a set of RV275 injectors would go nice with what you are doing. I'm running a DTT Torque converter and valve body with 275 injectors, my trans was in good shape so i did not need a complete rebuild. The livestock vb i beleive is a real smooth shifting so not to jerk trailer. Therre were a couple other parts installed in tranny to make it down shift in first (around 10mph)when coasting down to a stop. The 275 injectors did increase mileage slightly.

bullboy85

im lacking on hp too, thats y i was looking at the f1s, iv been told they do pritty good on mpgs and are great for towing, got to admit that 90 hp looks pritty good

wcbcruzer

HOHN's got a pretty good list. I'd say don't get a triple disk if you want to maximize mileage. They weigh more = more rotating mass.
