Okay... Massive update. Lol. MY JEEP NOW HAS A TWIN!!!!!!!!!!!!!!!



My dad ordered a winch for it so I got the task of putting it on the new Jeep... That winch was surprisingly heavy.

Old and rusty.

New hotness. (MIB II reference.
)

Mounted.

And this is what happens when you use a ratchet to undo the positive battery terminal and let it touch something that is grounded...


Covered.
Okay... Back to my XJ. Got the meth (washer fluid) injection installed and working. My charge temp is now down to a more reasonable # under boost. Still might look into adding a 25 shot of nitrous right after the filter element to cool the temps even more (since I'm running on the rich side under boost).




You can just barely see where the meth nozzle enters the inlet side of the supercharger.

Had to take a break since it started to rain...

Tried to keep the wiring and tubing as clean as I could.


Aaaaaand I found a good place to store one of my fire extinguishers and a can of WD40.

Not much to update...
Went to get groceries (chinese food) with my dad after we picked his Jeep up from having its brakes done (my red xj on the right and his red xj on the left) and I saw a "stock" xj so I had to try and park as close as I possibly could to it. Lol. It had a nice sounding exhaust system on it (not sure what brand).

And I finally got around to putting my "supercharged" decal/sticker on. Matches the color and font of the "4.0" quite well.

Might be getting TNT long arms in the somewhat near future...

Wonder how the 4.0 would take to a turbo. I def couldnt buy a super charger but i can come across turbos pretty regular in my line of work. Not to mention i could prob make my own plumbing. You might have me on to something here my friend lol.

I'm actually going to turn up the boost on mine a little bit (bought 2 smaller pulleys, 2.25" & 2"). The 2" pulley will probably put me at about 8 lbs of boost which makes me a bit nervous because I don't think the stock head gasket will be able to handle that much boost....
Here's something interesting. Absolute monster. Lol.

Haha!! It would take to a turbo just fine (there have been several variations on turbo 4.0s). These engines really seem to like boost.

Definitely sub'd.. I've been watching for ages for cheap LED headlights.. I'm beyond jealous. And you're ridiculously lucky that your parents will help you pay for stuff, I'm running purely on my minimum wage budget!

I don't want to blow my motor JUST yet. Lol.

Yeah... My dad found such a good deal on the TruckLites that I have. If it wasn't for that, I probably would have had to make my own. LOL.
I am in love with LEDs (which is why I made my own LED blinkers). I might eventually upgrade my fogs to LED (DIY) using some 3w LEDs from Sparkfun Electronics... And then maybe upgrade my cheapo HF fogs to LEDs. I kinda wanna go LED crazy...

I'll make sure I get a couple vids of some sort when I go to Rausch Creek at the end of the month for Rocktoberfest.

Hey. If I get a rear locker or LSD soon, I'll make a burnout video.

Pretty much. Lol.

n/a 4.56 vs. s/c 3.55 will be pretty even off the line, but once the supercharged one gets going it just takes off and leaves the n/a in the dust. Lol.
