Another ZC Question

Ok...this doesnt make sense to me. This is a 2nd post to my 1st one about a ZC. Anyways....my friend has a ZC in his CRX with ZC everything (engine, tranny, ecu). I beat his with my moms 97 Accord EX. I was wondering if i had the Si tranny(which i do) that if it would make a difference on how I could beat him with my ZC in my CRX. The guy that my friend bought the car from said it runs 15.5 here in colorado. I know that the Accord EX doesnt run that so how did i beat him? We raced from a roll and a dead stop and both times it was about a car length and a half. Thanks for the help.:D

maybe hes just a real shitty driver?:confused:

also, i thought the zc tranny had a little bit better gearing down low...but the final drive was whats shitty about it
