not sure why your mph dropped. so you ran 13.3 @ 102-104 with the 8 lb lower? and the only mod since then was a SBTB and your mph dropped?
only thing i can really think of is the weather. are you running in warmer temps now than when you ran the 102? the 8 lber heats the eaton up alot so higher temps will defiantely cause some hurting on the times without a good long cooldown.
also, depending how deep you stage, if you spin or not off the line, etc. can affect your mph more than you'd think. shoot, even if i just fold my mirrors back i pick up a solid MPH in the 1/4 believe it or not
well actually i have not ran the 8# at the track yet....that was a 6#er with a 13.206 at 99.4 mph....was going to the track and test but with the slight poppin coming from the exhaust while at idle and every once in a while when i get on it and then let off...i have been scared to go WOT...til i can figure out what that is...l was racing at fayetteville track in NC....and that track is just sad for traction....even with my hoosier slicks i would spin a bit...let me see if i can get a &*(^ video..
