I saw a 3-4 psi increase on the YSi as a result of the pulley swap. I also did chage to 1 7/8 LT over the previous 1 3/4 LT last year with the 8 rib setup. So that may account for 1 of the 3-4 psi gain
I really didn't want to go to cogs as my car is street driven.
My best 60' on the YSi and TKO was 1.40 on 26" MT Drags.
My best 60' on the YSi and AOD this year was 1.53 on 275/60 MT DR.
