Jeep Speed Goat TJ, the anti-build thread

If you need to maximize your airflow, keep your dimpled holes in mind. They'll allow airflow to the fan that doesn't pass thru the rad.

Yeah, I figured I could plug them if needed. They are pretty small at 1" and added for rigidity to the flat aluminum plate. As of now with the fan running, I can feel air flow up to 18" in front of the grill... it's currently moving a ton of air!
 
Had a chance to test out the new high CFM Spal fan & new shroud the last couple days with a trip up Cliffhanger and then 21 Road, the next day. The ambient temps weren't too high, 60's and 70's but there was enough low speed crawling and technical driving that the engine was tested on it's ability to stay cool. On both days, the engine temps stayed between 180-190*, never saw the gauge get above 195*... which is a massive change. The new fan is super loud, but it keeps the engine happy!

Another change I made was a smaller idler pulley.... last Summer in Moab when it was 100*'s out, the serp belt would contact the thermostat housing and sounded like a damn rod knock! It would also rattle every time I shut off the engine. I used a smaller aftermarket idler and put on a new belt and now it doesn't contact the thermostat housing!

Wheelin season is right around the corner and I want to make the old Goat a bit better, quieter and more reliable. I started with replacing the 15 gallon fuel cell and it's external fuel pump with the Goat Built 18 gallon fuel cell that takes a factory GM truck internal fuel pump and sending unit. I needed to figure out the fuel cell location, cut out the old mounts, weld up the new mount and space everything so it all works together.

Here's what it looked like to start with... quite the mess.

With the fuel cell change, I decided to relocate transmission cooler. It was mounted horizontally behind the fuel cell with it's own fan and created a lot of noise and heat. When I first got it, I added a piece of sheetmetal to redirect the heat and reduce the noise from the passenger area. I'm going to run a smaller cooler and relocate it in front of the radiator. I do want to upgrade the fan (again) to the Delta PAG that @Bart mentioned in another thread about relocating the trans cooler. I welded up the fuel cell mount on my setup table, then covered it with Seymour Stainless paint.

I also needed to fill in the holes in the floor out back, reorganize my storage layout and make a permanent mount for a Milwaukee Packout lunchbox cooler. Another big job was removing the leftover rear winch mount, built out of thick plate steel. There was a bunch of cleanup needed out back.

I've been running a Milwaukee Packout for tools, parts and oils, but with moving the trans cooler I can lower it down a good 8". I like having the Packouts for secure storage and an easily removable option. I left a cutout around the center-rear sheetmetal for a soft shackle mount, for recoveries.

I also capped off the rear 'bumper' ends that were wide open before. Its been a ton of grinding, cutting and welding and I've made quite the mess... but it's starting to come together.

Here's what it should look like with the Goat Built fuel cell, Packout and Lunch box. Lower COG, better securement and a nice fuel supply upgrade!

Looks like a great upgrade Greg. I was just telling Jared about that GB fuel cell the other day, for Everett's Jeep.

I like the Goat Built tank a lot, using a factory GM pump and sending unit makes getting parts easy, keeps the pump happy and the rotomold tank is beefy. Plus they offer the mount, making that a easy job too! And 18 gallons is nice for a long day with a thirsty LS! 😁
