ummh.. its all driving and pipe choice.. i was able to go 9 dry on my stock .25 with 2096/21 combo.... which is good for a 7.5 pit stop in my neck of teh woods... i will try the new carb on it.. next season see what that does...

on my X7 same track i was able to go 10.5 with fuel in the tank

i had a OS 28 that i was able to go 9 on also with fuel remaining... but that one was modified... and man did it run great...
