I changed the rear axle ratio from a 3:55:1, to a 2.76:1 and put a spool in it.. The turbo slant sixes LIKE numerical final-drive ratios in the 2's..... weird, I know, but they run better and faster that way...
Last time out, it went went a 7.6 / 95.5 mph in the eighth. That equates to a quarter-mile of about 12 seconds flat at 112 mph. That was done on 15-pounds of boost.
More boost is coming... maybe 20-pounds, the next time out. That should do something...:banghead:
