(Not an RBV) My Dakota.

Out on Long Beach on Monday. Truck got about 17MPG on the trip. It would be 18+ if I didn't drive 80 on the freeway, didn't drive on the beach, and kept my foot out of it

The Dak passed emissions today. Numbers are slightly better than stock! The cruise limit for HCs is 200 and the idle limit is 220. Stock cruise and idle were 124 and 119 respectively, now both the cruise and idle were 104.

I'm so glad we only have to pass the sniffer and there's no visual here

AFR was hovering between 14-14.7 at idle and around 15-15.3 at cruise.

That powerbrake vid is a tease! MOAAARRRRR!!!

My dad would kick my ass if I dug nice divots in the driveway And I just put "new" tires on, my last set was kind of abused so I wanna be a little nicer to these ones

So today I bought a fuel pressure gauge and finally got to the bottom of my leaning out under "high RPM" boost. The fuel pressure does in fact drop to 20PSI under "high RPM" boost, effectively turning 42lb injectors into 28lb injectors. Need to get off my ass and get a Walbro 255 in there. Video is first a 4th gear pull to only about 3000RPM (7PSI) and then I drop to third and pull to about 4k (7PSI).

[Professor Farnsworth] Good news everyone![/Professor Farnsworth]

I got the Walbro 255 installed today, not really a direct fit at all, had to dick around a bunch with it (they discontinued the kit for 95 and older Dakotas)

Took it for a quick drive, got into some boost and it pegged rich on the wideband from the huge spike in the VE table where I tried to compensate for lack of fuel pressure. After about 50 miles and a few data logs I've got the AFR about nailed, starts at 12 when hitting boost and works it's way down to mid 11s as I hit 5 PSI. Being able to use all my RPMs under boost rocks

Wewt...how did you end up fixing the snap ring this time around?

 

[Hahnsb2]

Got the proper snap ring and burned the bastard on.

Well I got around to installing an electric fan. It's controlled by Megaquirt and also runs when the AC is on. It's an OEM Jeep WJ fan, 19" across, 3" thick, and S-blades. It moves a LOT of air and is quiet.

Here's a couple pics. I also used some 1/8" aluminum plate to make a bracket to hold the overflow tank because A: I broke the fan shroud which normally holds it a long time ago, B: I no longer would have the shroud with the E-fan anyways and C: zip-ties holding it on was ghetto.

Someday I'd love to have a V8, 5-speed etx cab dakota, I like the 2nd and 3rd gen ones, a friend of mine is getting a 98 v8 5-speed and its a blast to drive lol

 

[Blake.]

i have one of these as my daily. cept mine isn't 4x4, a 5-speed or turbo'd.

Like i've said before on other boards, NICE TRUCK BUD!

 

[Hahnsb2]

Thanks guys!

Re-did the downpipe/exhaust exit, originally it went right near the tire pointing almost straight down. A couple months ago I changed it to exit straight out the side but didn't like the way it turned out so I re-did it again. Ignore my ugly welds, the 90s have been cut off and welded a few times, the welds are air tight though. It came out pretty clean and sounds better too. It's amazing how such small differences in pipe length, diameter, and angle can change the sound so much.

Well today I pulled the No-Slip and removed the synchro rings.

The whole idea behind the No-Slip and it's synchro rings is that it keeps the locker unlocked during a corner, so in a truck with a V8 and no weight on the ass end it will just spin the inside tire at hardly any throttle above idle, and to get it to lock you've got to use way more throttle than a corner typically calls for to speed up that inside tire to match the outside tire and then it will lock, which is very clunky and wastes tires. Removing the sycnhro rings eliminates this action and makes it function like a standard auto locker (Lock-Right, Aussie, Detroit), so instead of spinning the inside tire on a corner, it will just lock with no fuss or muss, and I'm certain that scrubbing the inside tire will actually result in less tire wear compared to spinning it. The other lockers I've own(ed) do not see a large increase in rear tire wear compared to the No-Slip.

I took it for a drive and it's SO MUCH NICER! Wish I did this a long time ago.

i need to do this in my dakota.
