that car should be running low 13's or less, in the 1/4mile at about 105+
it only went to about 43 in first
it's not off, 0 to 100 in abot 11 to 12 seg, that's normal, remember, the car is a little old, so the speedo may not be working perfect...!!
never seen a five liter pull to 50 or so in 1st......what gears do you have? check this website out for calibrating your speedometer, works good. http://www.hanlonmotorsports.com/t5speedo.asp
