The silver cans are slow, for sure.. lol. I've never had a brushless motor in my car yet (just returned to the hobby after a 13 year lay off). When I see FDR's that low my eyes get huge. The silver can gets to about 100-110 degrees after a five minute run. I could try another tooth. Maybe two.
Right now the fast guys can not pass me in the tight section when keeping the car as wide as possible and lines tight ( ie. careful, respectful blocking). But coming out of this is a right hand sweeper followed by the long straight. When the chassis' of the cars level out and the load of cornering is gone they can pull me on the straight and usually beat me to the next corner.
