The F.A.S.T. class car's are running in the 10's on reproduction bias ply tread tires.. They aren't joking around. I personally love that class cause it shouldn't be possible what they are doing..
Are you serious they're running stroked engines with big compression that run on race fuel only.. heads that have been hogged out intakes to match.. hugh cams.. carbs that have been tweaked too the max,rollerized transmissions ect ect..and those bias pyl tires are specialy treated too..the guys running in the 10's have more money in their engines then most have in a completely rebuilt car..not impressed.
