Steel City Racing: King of the Hammers 2019 Toyota 4Runner IFS 4600 Build Thread

[snivilous]

It’ll stay in CA till the race is over. We’ll do Cage then Wrap at the end. Then we’re off to JV for ON SITE shock tuning and testing. And we have a pro driver who is going to “immerse” us in all things KOH and The Hammers. I’ll be flying to CA as needed in Sept, Oct, Nov, Dec, and Jan. And of course KOH in Feb.

Most Tuning and Testing will take place beginning around Thanksgiving is my best guess.

Damn bro, you know they make racecars you can rent specifically for KOH

I assume you plan to race the East coast series?

More parts arrived today! These Fiberwerx front Fiberglass 4.5” Bulge fenders will really help us for the 35s while keeping COG low. I plan on installing them when the salvage doors are ready (should be here next Wed).

One step at a time. KOH is the sole focus. Then I'm hoping our sponsors will ask us to race other Ultra4 or even Mint 400 or Baja events in the 4th gen.

But for now, KOH is the only priority. We'll deal with everything else afterward.

 

[Charles4x4]

When I put in the Atlas II, will it automatically eliminate VSC (CDL will be gone)?

For the race, we want VSC Off and ATRAC selectable (with ARBs F/R of course)

For ATRAC, I was planning on adding a switch using this thread:

Took measurements of the cargo area stripped down for the fuel cell and spare tire last night. I'm thinking fuel cell on the platform just behind the rear seats today (removed for KOH) and spare standing straight up or slanted 45 deg toward the front over the rear portion of the cell.

The fuel cell area behind the seats is 42 W x 26 D.

The spare tire area behind the cell before the liftgate is 58 W x 14 D

Max vertical height 39" in center, min right at Liftgate 35.5" - will likely gain another 1" with full teardown.



We'll be using Alltech baffles - no foam. Researching fuel cells later today.

 

[Charles4x4]

Haven't had a ton of time to search, but there seem to be really cheap and really expensive fuel cells. Jaz Pro Sport II seems to be right in the middle with good reviews.

Wide & Short 22 Gal (34-1/2"L, 18-3/4"W, 10-1/2"H):
https://www.jegs.com/i/JAZ/547/280-...vRfKEjKK9AdZMxG7T7j__Q1av8h8U5IhoCCYYQAvD_BwE

Wide & Short 32 Gal (34"L, 17-3/8"W, 14-3/8"H):
https://www.jegs.com/i/JAZ/547/280-...X6XgXeoE5-Fh1pbkEwfyXGFvuseCjG0RoCJiUQAvD_BwE

I can fit either and Artec makes a nice mount for both.

I can see the need for a 32 Gal cell with a blown LS that gets 3-4 MPG. But we're using a slightly modified 4.7L Toyota V8.

- Is the extra capacity of the 32 Gal needed and worth the extra weight?
- Is there high probability that I'm going to need more than 22 Gal between pits at KOH or other Ultra4 races, Mint 400, or even Baja if that dream ever comes true?

 

[Charles4x4]

Stock 2016 V8 MPG is 17/20. Cut that in half for race conditions and power modifications we've done. Maybe 8-10 MPG. 5 MPG worst case scenario.

- 10 MPG and 22 Gal = 220 Miles
- 5 MPG and 22 Gal = 110 Miles

- 10 MPG and 32 Gal = 320 Miles
- 5 MPG and 32 Gal = 160 Miles

2018 KOH Total Distance:
4400 = 202 Miles
4500 / 4800 = 136 Miles
4600 = 124 Miles (us)

Given the Main and Remote Pits - Even at 5 MPG I don't see how I need more than a 22 Gal cell right?

If I ever get to race it at Baja, that's a great excuse to upgrade to 32 Gal.

Why not just run a 32 from the start? Unless there's some major drawback to more fuel, I would run the biggest you can.

Only weight (60 LBS when full) and height (which could affect Spare store fitment). Otherwise it’s a no brainer.

 

[Charles4x4]

Just Curious - why would the Pioneer head unit be wired into the harness in the back near the factory JBL sub?

Saw it while tearing out the cargo area and had to ask.

I’m going to try and keep the head unit as I can turn camera view on full time, which may come in handy for a camera on the front bumper when we’re strapped in and can’t see over the hood.

 

[Charles4x4]

Anyone know how tall/long the OEM Fuel Sender is? Hoping it’s less than 10” long.

 

[Charles4x4]

We're excited to announce that Cooper Tire and KMC Wheels have signed up to sponsor this King of the Hammers build.

We'll be running 315/70R17 Cooper Discoverer STT Pros:

These will be mounted on 17" KMC XD222 Enduro Beadlock Wheels:

With Cooper and KMC on board, our sponsorship for KOH 2019 is officially full. We'll have more to show on the tires and wheels, and from our other sponsors over the coming months.

Quick Build Update:
- RockSolidToys Rear 4-Link is done and ready to be installed once the front suspension is on
- Currie Rear RockJock 60 is in the middle of being built
- Salvage Doors (4) should be here next week. Evidently they were were stuck in a "rail delay" somewhere between CA and Chicago.
- Salvage Liftgate and Sport Hood will ship out of NY tomorrow.
- Jaz Pro Sport II 22 Gal Fuel cell, Arctec Industries mounts, and Allstar 2.5" filler hose in the mail.
- Still working on Alltec Baffles and plumbing conversion, which I still need to learn a lot about
- AEM Air/Fuel Ratio Gauge, AEM Fuel Pressure Gauge, and URD 170 Deg Thermostat will be installed when URD MAF Calibrator arrives
- PRP Ivan Stewart Pro Seats and Harnesses should be shipped out soon
- Cooper Discoverer STT Pro Tires ordered
- KMC XD222 Enduro Beadlock Wheels will be ordered this week
- ABS (and ATRAC, VSC, and TRAC) Defeat Switch will be finished next week
- Atlas II 3.8 Case and A750F Adapter will likely be ordered next week

The salvage parts arriving next week will literally replace every single removable piece of sheet metal on the 4Runner.

I'm tracking every component of the build in a build-plan and checking things off the list as we go. Still a lot left to do, but having the sponsorship portion of the build completed is a big win!

Keep us posted on dates for the nov-dec prerun. Maybe I'll make a run out to JV to come watch this thing in action. Can't wait to see it finished.

I'd be down for that.

 

[SAC-CA-Runner]

I'd be down for that.

Me too. Another reason to get out and camp/explore/meet new peeps!

I'll start another thread in the So Cal section when there's dates as I'm sure there will be others that would make the trip. I've never been to JV but I know there's some awesome crawling to be done out there in the Cougar Buttes area that I really want to check out this winter. Didn't get the chance this past winter/spring due to rig and medical issues and preplanned trips.

Yep. We could put one in the NorCal forum as well, ya know, for us NorCal'ers that would make the trip. ::biggrin2:
