LOL.

33s and 3.55s was not that bad at all honestly on road.

on trail it sort of sucked.

You must have failed HS algebra then. Your crawl ratios are wrong. Garbage in, garbage out......

My BA is in Applied math and MA in Economics and Applied stats ... The order doesn't matter in multiplication. AxBxC = CxBxA = BxCxA. Its the Associative property of multiplication. I think the issue you might be stuck on is some rounding between calculations. I could care less about the second decimal place in an application like this. As for those gear/tire and weight ratios, those are just my brainstorming for a random 30 second time period and though other folks might like to see some of the break even points between tcase, axle gears, tire size and weight, just by plugging and chugging a handful of cases. To normalize for tire size and weight, so its not a "thing" anywhere, I was just showing that the same crawl ratio on a heavier rig with bigger tires is not the same as one that weighs less with smaller tires, thats all. I think you multiplied by 2.7 and not 2.72. I think some of the cells were set to 1 and some set to show 2 decimal places even though the value was 2.72. thats no big deal.

I have a BA in BS and my GPA was so low that I am now SOL and my carreer is DOA. :dunce:

At least your calculations were consistently off, so comparativly it is correct. But, if you want to get super technical, the torque converter has a multiplication or slip flactor of 1.7:1. While you are correct to compare apples to apples, there are some variables that will skew your numbers when comparing to a manual trans rig.

This is kind of like watching Jon make cornbread. :gee:

yeah I was ignoring the torque converter in this case, but that could be another line item.
Where did you get that 1.7:1 anyway? Ive never actually known what the factor is for the AW4 or any tranny, only that the TC helps crawling......

I learnt that in school. :D

Apparently that is the engineering spec that the factory uses for its final drive calculations. I know lots of useless information about Jeeps, math not so much....
 
I'm very impatient and impulsive and these 2 things often overpower my rational side. Coupled with enthusiasm and the occasional strong focus on a task.

The first step is admitting you have a problem



So... Did your atlas come in? Why is it not installed yet? It's been roughly 48hrs since you've been home. I'm starting to get worried.
 
atlas is here....
I have been so tired and catching up on just regular life and work. I need some help installing it. Im being lazy. I need a kick in the butt. I was hoping to install it by now.

Rudolph,
if you need help in calc 1,2,3 or linear algebra, number theory, statistics, differential equations, complex analysis , real analysis, abstract algebra, real analysis, upper division geometry, econ, econometrics, statistics, statistical inference, applied statistics, research methods, data mining, factor analysis, multi dimensional scaling, discrete choice analysis, survival analysis, and maybe some calc based physics I can help ya out. Or R, SQL, SAS, Tableau, teradata SQL, SPSS.
Ive been working in data mining and applied statistics and forecasting for the last 8 years. I used to tutor math for like 10 years.

I never went to classes before 10am so if you are taking history of math or chemistry I cant help you out...

dude. Lou.
If you are serious ill take you up on that.
And I will owe ya one too.

I'm down. Last day of vacation, might as well spend it doing something fun. Let me know what time you want to start.
Click to expand...

well, ill be on your schedule. what time is good for you? you're the one making the long haul. I can be out there any time you want to show up. Actually, I can start earlier to get tools ready and stuff.
 
You know reading your threads makes me love my xj and want to build it more. But right now I have it dialed in perfectly. Loving the 4ds they are sexy.
 





 
Upgraded headlights to rampage h4s off amazon and putco wiring harnesses . Easy install and looking forward to being able to see at night while
Driving a Xj based rig.

Mj is getting a putco harness and Sylvania silverstars sealed beams .'

Got everything on Amazon for dirt cheap
