unless you have a very nice GPS, and i mean, very nice, the variability is to high.still fail......
you have to have reliability to get concrete data.sorry ben, but your rigs are not reliable.(proven by your own posts, not bashing)
the driveability is better with a 5 spd period.
and the rpm's drop about 500 rpms throughout the range....this was tested on a 1986 brat with 185/80/13's,205/75/14's, and 235/75/15's.on a 1983 wagon with 175/70/ 13's and 235/75/15's.
you originally stated"maybe a little higher"......
that is what i went off of.cheers, brian
