There are a lot of small track carpet guys posting here. This is normal as they are the most vocal....but please keep in mind that MOST ROAR members live and race in CA, FL, TX and other states where we run outdoors most of the year.
In FL we have at least 6 permanent asphalt tracks. The smallest is 120x60. The two tracks in Tampa are 170x50 and 185x85. These are normal size asphalt tracks for 1/10 sedans and 1/12th pan cars.
Many of the issues described in this thread are all about too much power for tracks that are 90x50 or smaller. Sure a 13.5 is fast on a typical 60x40 carpet track but on a bigger outdoor track all of the classes spread out becuase the Mod and 10.5 guys can use their power.
On these tracks Mod is about 2 laps faster than 19T. Thats how it was at the Reedy Race and the 2006 On Road Nats.
Running 13.5 as the 19T would be bad for all the asphalt guys. We like 19T and 10.5 is like 19T. We don't run 23T which is like 13.5.
