What's the slowest car you've raced in the 1/4 ?

13.6 at BIR in a 92 Stealth RT-Twin Turbo. I blew the intercooler piping coupler off the throttle body when I shifted into second so it had no power for the rest of the 1/4 mile. At that time I was using worm gear clamps instead of T-bolts so we slapped a second worm gear clamp on it and it still blew the coupler off. Never was able to get a decent run in that time.
