Well there isn't a 1/4 track to close to me but my old 1/8 equals around a 12.6 on the motor so I am hoping to stay in the 12's with the C4. I use to run 8.10 in the 1/8th and my buddy runs 8.30 in the 1/8th and insists that I will still be able to beat him on the spray (75hp) I should be able to stay in the 11's I'm hoping I might go a hair faster with the C4.
I'll post track times
