I ran a 13. 87@96. 7 with my stock hx35,It does have a 14 housing on it,and i ran it with a G-tech,not at the track,so it may be off a little,from the cars i ve raced,i would say its right on the money,ET wise. I know i could get the hx35 in the 13. 6 range with the new race TC,and an earlier 3-4 shift alone.
