I've been working with a buddy of mine out here on his '05 Dakota (4.7L).
Custom ground cams are coming from CompCams (already sent them the specs we
want), Cold-Air (home fab - $60) is installed, Viper Fan has been mounted
(from his old Dakota), and his mileage went up 1mpg with just the Cold-Air
and Viper Fan.
There is a better alternative than the Viper Fan though - less work and
comes with everything ready to install ($240) - BlackMagic "Extreme" 180
electric fan (mounts to the radiator like it was made for it - it's a
3300CFM single 16" fan.

Subject: DML: Dak 05 v8 performance suggestions wanted
Greetings all, I'm new to the DML list - been lurking for a couple weeks,
time to ask a question of you.
I recently traded in my 98 Dak for an 05 (Mineral Grey SLT, quad cab, 4.7l
v8, 5spd Auto) - yes, I know I'm in the minority, but I love the look of the
05's, the body style and retro gauge look reminds me of the first vehicle I
bought back in '76 - a 72 Dodge short bed (360, 30-over 9.5:1 pistons,
Offenhause dual port intake, carter 650, purple shaft cam, 3600 stall
converter, damn that thing screamed). But I digress...
Anyway, I've been working on the improvements I want for my '05 - spray in
bedliner, tonnaue cover, side step rails, etc. The next area I want to
focus
on is performance and/or gas mileage. While I'm pleased with the snap of
the 4.7L, there's always room for improvement - right? Plus, even at best
with the day to day driving I do I'm only able to get around 15.5 mpg (17.5
if I have a long freeway drive). Lots of start/stop on my daily drive, plus
living in SE Wisconsin, we're victims of having to use reformulated gas ..
10% ethanol.
Gotta love the reform gas.. lowers gas mileage (fact), ruins your fuel
injectors (fact), increases gas prices - and basically does nothing to
improve the air quality. And don't get me started on the fact that Wisconsin
has the highest gas tax in the country. Bitter? Maybe, just a bit - but
again, I digress..
Anyway - looking for mods that will help performance and/or mpg, ones that
are
reasonable in cost and won't void my factory warranty. Any suggestions you
might have would be greatly appreciated.
