run #3 best one and last one for me

6.175
8.791
9.364 1/8mile @78.52mph


my previous best w/o 17* 1/8: 9.374@ 77.60mph

with 17* 1/8 9.364@ 78.52mph it really makes a difference in octane and timing advance

 

Judging by your previous time without 17*, not much of a difference than with the 17*, maybe you were probably getting some detonation and knock sensor was taking back timing.

 

gained one mph on the 1/8 by doing the 17*.. and if i had some time i wouldve pulled 9.2 if it wasnt for the 87. im going back to track again on friday with 93 octane.
