After around a month waiting for misc parts to show up (well still waiting on my bypasses, chormoly links, and axles) its time for some more progress.

Gotta love when a plan starts coming together.

I've long thought about a supercharger, I just haven't been able to justify it for my needs. If I had the trails with the "room" to let it fly, I could see it. Most places I travel, its tight with no room to let the FJC stretch its legs.

Thanks for sharing, it is surely going to be a well built rig...:beer:
 
Trust me, I've got no real justification for buying one either. With the Aux MAF tank the gas pumps already shut off automatically before I'm completely filled up. This is because it goes over the max Debit or Credit amount that pumps are authorized for (usually ~$100 or $125). Its going to be rediculous pulling out multiple cards to pay for premium gas to fill up the FJ. Won't dive in to the added maintenance, wear on parts which will occur due to a potentially lead foot, or the fact the FJ's shapped like a brick from the get go haha.

Yet somehow I have one sitting in my garage right now haha.
 
I won't have one before summit; however, if I could find an X-1 or similar EMS I hope to get a SC soon.

Let me know your thoughts on the reflash.

I'll keep you posted


The truth is that if you don't snag that one up so quickly, I'd been contacting the seller also...:beer:

lol, my justification to my fiancee was, "it was on sale and I saved $800 over what I could order it online for". Which simply prompted her to ask, "well what does a Supercharger cost?"....:doh:. I guess the same "it was on sale" tactic she always uses on me doesn't work both ways.



Heading up to the shop now to check out the floor which Dave chopped out to tuck the TC away a bit.​

Sweet setup, you gonna race Nick to the top of a something...?
 
I'm racing Nick to see who's FJ actually gets done first. Winner will hopefully get to enjoy their vehicle for more than a couple weeks before the next mod hopefully. Think his has been at the paint shop for a month now.

I'm just fortunate that Nick and Metal Tech went through a lot of the learning curve on the 3 link, so it made the work much easier for Dave even though we changed all of it around. At least provided a good starting point.


There's actually another interesting build going on in your part of town. FJ running a custom hi9 & custom rear frame/4link, 12" coilovers and rear bypass shocks. Neat setup, just a lot of different decisions - guys running a S/C with 10lbs of boost which is MUCH more than TRD S/C comes stock. Said that the reason for the axle upgrade was, so that the drivetrain can handle all that power, but at the same time is running a stock front dif & a lefty case with XD gears. Those are just as big of weak links as the rear axle was, which is something I'd be a bit concerned about.

Some items like that and the shop claiming they get 12" of travel out of the TC 2" LT system, which TC claims 11.5" for, and where several folks now have measured only 10" of true travel on that same suspension, left me scratching my head a bit. They definitely went through some firsts though and came up with unique stuff.

Just nice to see folks starting to push the mods to another level and start toying with the frame, body, and more dramatic suspension systems. Really adds a lot of value back to the community for those who might want to go in a similar direction or further in the future.
 
New cross member for the Atlas coming together. It'll have a bushing tied to the rear of the Atlas.

Substantially modified NWF shifter setup going on the Atlas. What they sent didn't quite work due to the adaptor plate

The one thing on that build that I don't like is how low the frame winds up below the cab (due to the body lift, I assume).
 
Yes, thats due to the body lift. Which is what they will claim gives them more travel on the 2" setup than most. However, the UCA & LCA uniballs are at max misalignment when you get close to 10.75" of travel and the LCA is going through your rotor (with his TRD brake setup it should be even more limiting due to the rotor). I know Nick never got any wheel travel numbers from them, which really makes me doubt they even attempted to measure the wheel travel. Think it is more of a pissing contest based on their writeup.


No doubt the fab work is sweet though and they did a clean job. Just a few things that leave you scratching your head as to why.

I imagine they were just quoting the 12" (rounding up) from TC.

I don't know how much travel I am getting in the front with my 2" kit from TC, but I suspect it can't be much more that 1" beyond my old Icon extended travel with Icon UCAs. I will tell you that my UCA was the limiting factor on my old Icon setup, which is saying alot because that uniball and bolt can go like 60 degrees. The reason I know it was the limiting factor is because when i took it off, I had rubbing on the spindle bolt and the UCA where the bolt hit.

Cam provided a response to my inquiry. Basically they never measured, but will be doing so next time the vehicle is in the shop.

Can you explain how you are getting 12" of travel out of that front TC setup? Just curious since TC says its 11.5" max and those who have installed the TC setups before (2" and 3.5" kits) all measure below advertised. We were just getting around 10" of travel with the TC 2" kit before Dave pulled it off and we went with the Camburg 3.5". The TC 3.5" setup on the SDHQ FJ only got a hair over 10" of travel before they yanked theirs for the camburg as well.

Even with a body lift the upper and lower uniballs would be issues at much more than 10" since they are nearly at max misalignment there. Would there not also be issues with the inboard CV at 12" of travel? With an 1.5" longer axle than what he is running the inner is pulling out of the cup at bump and axle binds on the cup at droop at around ~12-13" camburg kit.


Just trying to understand how you guys are getting 12" out of the TC 2" kit when most other folks haven't even been able to get their claimed 11.5" of travel.



Honestly, we never measured it. Just took the manufacturer's claim. But we did not have any of the issues you had with the bottom bolt hitting the brake rotor, and the upper a-arm never stopped at the inner fender because we had the body lift. I will have to measure the next time it comes in for maintenance. Despite what they say on the TC website, the TRD brake upgrade package had zero clearance issues on our truck.

Had no idea about this CV/shaft bindage problem. I'm interested about what you guys experience with the hybrid CV shafts that will be prototyped on your FJ. I won't spill the beans though.




I just want to see the factual information posted (and if they are getting 12" of travel out of 2" kit thats awesome and hopefully they can educate everyone on how), but if they haven't measured and are claiming that it sets out some potentially false information. The next guy who buys a TC kit because he read you can get 12" of travel might be quite dissapointed with the money which he spent if he only is getting an 1.5" or so over his previous setup.

Well after 4 months of waiting some sexiness showed up at the shop today. Were supposed to be a piggyback, but not a big deal.

I saw your rig at Javier's when I was over there. They are doing some top notch work. I swear they have some of the most beautiful welds.

Dave's fab work makes me drool everytime I'm up there. They definitely do top notch work. I've really come to appreciate how Dave actually puts some significant thought into his builds. Feel like a lot of shops would simply slap on what you give them. Small details like mounting the rear coilovers forward through the wheel wells to leave room on the rear for bypass shocks and mounts (if we choose to do those down the line) makes me :clap:.
 
Been awhile since I updated this thread.

Dave's working on custom shock hoops - which will be completed once we get the geometry on the axles right. We'll be using the bypasses as bumps, so we'll need to axles back to see how much travel were getting before finishing that up.

Should go a bit faster now?

X-runner folks are putting ~340hp & ~360ft/lbs down with same setup on 93. e85 bumps the torque up to ~400 and hp to ~390. Hopefully will get the FJC on the dyno by years end to see what it puts to the wheels for comparison on the drivetrain losses. Should be interesting to see what influence the geared transfer case and crawl box have. Know one guy who dyno'd his on a 4wd dyno put ~270 to the wheels with the basic TRD kit​
