I know alot of people seem to think that 203 is faster in 12th scale or just in general but this weekend I was able to Tq both super stock Touring 17.5 and 12th scale 13.5 with 212 over some very good drivers.
In 12th scale my motor actually came off almost cool to the touch and I tqed by a lap with my hotlap and finishing laps only .3-.4 different.
Which I think is about as good as you are going to get in 12th scale spec classes.
I also ran 212 in the main at Cleveland and finished 2nd in 17.5 boosted 12th scale.
There are settings that are not perfected by any means just things I am throwing at the car and they are working decently. I think once I hit the sweet spot the lowered temps in 212 will actually produce faster runs and cooler motors overall.
