a 8.9 8th mile time wont neccessarily yield a 13.5 1/4 mile. as a matter of fact, i highly doubt that it will. my 13.8 runs had 9.0 8th mile times, and i have more displacement/high end power than you. you cant go claiming times you dont have slips for 
anyways, about the jnmm, you guys might want to know:
its not compatible with the zex system
and its also not compatible with the msd digital 6 (i think)
also, you NEED an aftermarket ignition
