I am running 6:1, 35" boggers, and locked 529 gears in Yota axles. I drive it around town all the time. I can peg the speedo at 90 and still have pull left, it is at about 5200 on the tach. It is a little scary at that speed, but is hilarios to watch peoples face when you fly by them. I do not know the REAL speed with that combo it is not 90.
With the 16 valve 4:56 gears in Zuk axles and stock tcase, the speedo would hit 100 and have a little left. Does anybody know how to figure speed by RPM with my current setup? How about crawl ratio?
