HUH? If I had known you were there I would have brought over your present.

Sitting on tires, everything moved a bit further along. Rebuilt 4L80E from Tranny Tom is hooked up to the Atlas 2.0 and installed in the rig. Trying to get as much done around the engine as we can.

Looks awesome! Any concerns with the higher first gear of the 4L80E coupled with the higher low range of the Atlas not being low enough for crawling? Obviously it's light enough and powerful enough that it shouldn't be a huge issue, just wondered if it's a concern at all

Hopefully not. In most of the races, the obstacles aren't the same as a competiton rock crawl where there's a lot more technical driving. Most of the obstacles require getting through an area quickly with less restrictions on the line you have to take, so it should not be an issue.

The hope is to be able to run all or portions of a race staying in low range to limit shifting in and out of gear. This is an especially good strategy at races like Rausch Creek where there aren't long high speed stretches, so he can run 4th gear in low range near red-line up near 70-90 mph, depending on how the new engine mods like hanging up there for short bursts.

Shifts into and out of low range can take 10-30 seconds depending on if the shifters bind up, so it can be quite an advantage to roll up to an obstacle, clear it, and get back up to race speeds. Sometimes making the pass going into an obstacle due to them not getting a clean shift could mean a big speed advantage.

As a comparison, Randy Slawson in his Bomber buggy tends to run most of KOH in low range, but runs 4.10 gears vs Mike's 5.40; so he has even worse crawl capabilities.

Our hope is to get some good prerunning in out at KOH so we can nail down the strategy. For RCQ we had marks dropped on the GPS that showed when to shift in and out so the co-driver could call it out, hopefully we have very few of those.

...that is no joke... I don't think I'm going to bother shifting in the qualifier.

We got the engine back on Friday night after a couple of frustrating days at the dyno, and no run time. Mike had a new harness made that turned out 99% awesome, but was lacking one power wire that caused the dyno guys to not be able to tune the engine.

Within an hour of getting the engine and harness, Mike and I were able to track down the issue and patch in the missing wire. It should be good to run when we get to that point, but it looks like we'll tune the engine in on a local chasis dyno instead of the engine dyno.

We re-flipped the intake to fit in the chassis and tried to install the engine on Friday night. We figured out that pulling the crank pulley was gonna be the ticket, and called it a night.



After some sleep and with a smaller 3-jaw puller on hand, Mike and were able to drop the engine back in the chassis on our first shot. Two tabs were in the way, but no big issue.



WhiteRhino stopped by and he and I made up some new engine plates that raised the engine about 1" to allow a bit more uptravel. Meanwhile Craig (Vu14TJ) and Mike laid out the wiring harness and adding heat shield where needed.

I guess I forgot about the new torque convertor. Before we married the engine and trans, we installed Mike's new TCS torque convertor. He ran last year with a stock 4L80E TC, but he wanted to take advantage of the cam and head upgrades so he stepped up. There's no lock-up and it's about 2800rpm stall.

He also picked up this trans cooler. With the radiator in back, we can fit it in the retrurn line from the radiator to engine to cool the trans. Come to find out, it's not much easier to package than a air cooler, but now that a spot has been found, it should be sweet.

The radiator got to the shop on Saturday night and we got to work installing it. It's a BeCool 36x19 with two 16" SPAL fans. It should have no problems keeping the motor cool, as last year he ran a 26x19 with to two 11" SPAL fans.



PAC also made up some new posters. These turned out sweet.



On Sunday, Mike and Craig continued to knock out tons of stuff from the list. Engine should be ready to for first fire soon.

Yesterday we spent some time getting the remote oil cooler mounted with a new bracket. Also got the power steering cooler and oil surge tank mounted. Had to make new lines for the remote trans cooler.

I'm hoping to make the new switch panel labels tonight.

Keep awn it guys, tick tock tick tock.

I'm rooting for you to have a trouble free fire-up and some quality tune time with hopefully a few hours of relaxation before race day.
