They have seen decreases in all times (60' and 1/4) but nothing on paper yet. Every single reacts differently to the amount or air it lets in and out, so it would be completely different for each motor.

Yeah I know. Basically I was just looking to see the gains on ANY engine to see if your work was good. What kind of 1/4 mile improvements have you seen? What other mods?
