small update i guess, junk i've been working on this season.
new thermostat and water pump. seams like the water pump might have made a big difference in cooling, no clue what could have been wrong with the other. don't ever buy a motorad thermostat cuz this 180 is actually a 195, same as the reviews.
wouldn't ever buy an android based radio again, the next will be a wireless android auto with a general interface. thinking Kenwood for the XJ.
waxed a 2nd set of 5.13's in the rear axle ... 2 different installers and i trust both, very deliberate break-in this last time. general consensus is either that the supertech 80/90 isn't up to the task of 80mph with that pinion speed, or the case is somehow machined off a bit. i set up a used set of 3.55's and could see the old really good contact, there was NO way i could get anywhere near it in my case so i'm leaning to weird case machining. these really make a lot of noise after a LOT of set-up work.
switching back to 3.55's is WAY better than the 5.13s (on the street)!! with the 3.55's i drive it like a 4spd with a useless OD, with the 5.13s i drive it like a 4spd with a useless crawler gear. but worst case if i throw a 4:1 in the d300 my crawl still works out fine. with 5.13s in actual 1st you redline before even getting past the start line, it's USELESS short on the street.
using the low first as 1st:
3.55 * 5.61 = 19.9 ... 19.9 * 4 = 79.6
3.55 * 3.04 = 10.8
using 2nd as first:
5.13 * 5.61 = 28.8 ... 28.8 * 2.62 = 75.5
5.13 * 3.04 = 15.6
5.13 * 1.67 = 8.6
so really the 3.55s give me 27.5% more torque to ground off a stop sign, and 25.5% more torque in "2nd". way way better.
i'm trying to get a stock 3.55 3rd and swap in a 35sp spool to have a spare 3rd and use in the mean time. then i can wait til spring to order a new big bearing 3rd with the posi.
