My main reference on what guys in Brazil run is from Douglas.
IIRC,going off memory, the top 250 CI guy that runs in a street radial class (no drag radials) is 11.70 ET & his engine along w/Douglas' 250 were bored to 4.0" running 13-15:1 compression & up 10% nitromethane & the top guy makes 490ish HP, again going from memory.
He is planning on making 700 HP w/a 292 N/A currently.
