Are American tracks really THAT small?
I ask because my home track is about basketball court size and despite being very low grip at times can handle 10.5 1s OK when the grip is there and I think would handle 13.5 or 17.5 quite easily. Depending on the layout we choose, lap times can be as low as 9sec and as high as 15sec with 21.5T TC
It varies, but some tracks, like my local track in Jenks, OK, is VERY small, like maybe the size of a 2-car garage(maybe just a bit longer though). We've been trying a number of different motors in a couple of classes(like minis & touring cars), & have actually found that 21.5's seem to be ideal(I've done runs with a 17.5 along with a friend running a 21.5, & I only had a tiny edge at the very end of the straight & into a sweeper that follows it, can only use it for another .1 sec. or so, & then only if I'm not following anyone) so lately, we all just use 21.5's. And in 1/12 scale, no one I know of has had the guts(myself included) to even try anything faster than a 17.5. I think fast laps with 17.5's in TC are about 6.1-6.2 sec., with 21.5's it's more like 6.2-6.3, & for 1/12 scales, we're just recently dipping into the 5.9 range with 17.5's. Very small & tight, but still a LOT of fun....
