The octane was raised about 7/10s of a point in c11 c23 somewere from 7to 9 and the c25 was raised about a full point. The pro stock motors were having a problem with detination so the change to c 25. C11 was always for a little lower compresion motors and when ran in higher compresion motors it to had its problems. It maybe just to bring things more in line with todays motors higher rpms. I think the prices will be about the same but if car gas goes to 5 dollars race gas will follow. Tom
