It has been pretty enlightening hanging around the shop as the build continues. Yes, there were drawings, from detailed (IFS) to a rough frame with seats, rear links, etc. But, as you will see there is a lot of in-process scoping from the builders and crew to get it right. Work, back-off, work, back-off, etc. What you might also see is the relatively simple ways that the parts are put into place. What you are not seeing are the bending, coping, cut-off, and other special tools that keep the tolerances tight. Plus the Masterfabber to adapt from the drawings the small changes.

Here, is about Mid March, as parts start to be positioned in-place and should encourage "above normal" builders that they could really do it "at home." Today it is non-photogenic as it looks like meatballs and spaghetti with out the sauce and parmigiana. The story and recent pics are being created and I do hear some roller/dyno scheduling dates being thrown around so...

I think that it should also be said that Jason and Dan have "builit" several winning cars, and know where they are going with this build. In the early years of KOH Jason would build, race/test, and come home to cut out what they had built the weekend before. Many of his rigs had multiple re-works, looking for learning and perfection. J's comment about more scrub to search for traction when stuck in the rocks, is learning from previous (crawler) builds, and maybe not needing 0 scrub in the fast, as was thought. " Intended compromises."

To try to keep J in the shop and our cameras have been banned, I will try to answer. Actually Dallas or Tim should. They had to work extra hard to get the geometry to work with the uniballs. The top uniball actually covers over the fastener at full articulation. But, I believe the short answer is turning. There wasn't a way to get the turning that this design is capable of with vertical balls.

On desert cars, where turning is minimal and articulation is the greatest, they probably prefer vertical omniballs for more strength and best wear. When the race leaves the ball at the flats, it accumulates crud and wears quickly.

Full load on the front end at full lock and articulation doesn't happen that often...Hopefully. Horizontal balls are now common on the top to get good geometry with a reasonable upright design. It is the lower uniball that gets re-oriented depending on steering. (As I see it)

Can't wait to see Loren's build also!!!! It is interesting that the top teams seem to be using the pro's to design the 4X4 IFS geometry and parts. I tried to do it myself, and I am now on Dallas' list.

Sitting beside the transmission, now that's what I'm talking about! I like what I'm seeing here, and as always Trout's fab is second to none

Doug, the limiting factor in my last car was the uniballs / amount of misalignment. Figure about 32' of angle for those, then cycle the suspension and find out that if you have to limit those almost 5 degrees with the Ackerman and bump steer and you have a whopping 27' of steering. When we finally bought the rezeppa style outer 30 series cv's from RCV we found they turned 45' stock. So the new design was based around maximizing the steering while still having the same or more travel. It's looking awesome but it's a lot more work to get a arm clearance, strength and geometry than just traditional arms.

awesome build i cant wait to see how it turns out, ive always been on the fence about the ifs cars but after reading through a few build threads on here im becoming a believer. i sure hope one day i can build at a caliper close to that of this build.

More pics and Part 3 of the series is up and running. We've been having a few issues fight us but the solutions are pretty solid...loving the way it's coming out.
Fingers crossed we can fire this motor off Wednesday night and get on the dyno Saturday to get it tuned...then it's off to testing and testing and testing.

We have a few items we are trying that might not work...and we know it...but we have to try. If they don't work we've got some late nights to get ready for Stampede but if they do it's going to be a cool setup. One of them is the severe angle from the trans to the t-case. The angles will cancel but the joints will work pretty hard. If they get hotter than about 200 degrees we have to move the t-case....the dyno runs should tell us

whats special about 200 degrees for ujoint temp? grease or seals? if you're interested I know a grease guy there in southern California that makes grease all day that lives at 200 and above. i'll get you his info if interested.

great looking build, thanks for sharing on pirate!

You know that's a good question...I think the number was thrown out there.

What it needs is a good 45 minute WFO session and then full inspection. Maybe do a 15 minute run first and check to make sure it's not melting the seals and rollers out first but you are spot on, the temp is arbitrary, its the damage that occurs if it gets to that unknown temp. Either way it's something we need to go test and that should be able to happen in about 8 days!

Yesterday was awesome...everyone pitched in and we got a ton of little lose ends done and fired it off. It was pretty awesome to see it fire on the first push, then it took a little throttle as the TPS either needs a little tuning or I need to throw a hole in the butterfly but either way it runs perfect and everything looks great....oh and it sounds Angry

Great evening guys! J SPARED the neighbors from a 10PM ear splitting. I am sure it will sound different on the DYNO!
