A buddy and I have been making a few passes at the track with his ex cab and ran into an interesting debate. We used my drag radials last year a few times and where very consistant 13.92-14.03 pass after pass. This year he is using a full slick that he had purchased and we netted 14.01-14.19. The only changes made where since last year he had 3.73s. This year 4.10s. The 60fts are extemely close but we lost mph and ET. We both expected it to pick up ET, not slow down. So begs my question.... Do you think the softer tire is eating hp? We will be back to the track soon with the dr's from last year and the new slicks.
