I was wondering if any one can help me. Ok, i have a 02 z with full exhaust, air lid, sub frame connectors and strut tower brace. last year at Memphis i ran 12.898@108.63 with a 8.417@86.82 1/8 with 273 gears. I changed my gear to 373's an i ran 7.98@88.54 what should i look for in the 1/4.

 

can someone help

 

I used a 1/8 to 1/4 mile converter and with your 7.98@88.5 in the 1/8th mile I got approx. 12.5xx@109.xxmph.

Nice gains from a gear change BTW. What was your 60'.

 

Your looking @ anywhere between 12.40-12.50.
