why is everyone so set on the xp when the s1x has outperformed it so many times.
zzp claims highest hp for stock heads. but dyno #'s dont really mean jack. no dyno was created equal. no two dyno's dyno the same. most dyno numbers are a calabrated number/correction. you can make a dyno read whatever you want it to read.
im just sayin...
don't you have to run 130 lb springs with the sx1?:th_scratchhead:
