Talking na 20b with bridge port....

hey guys,

im no big expert on naturally aspirated rotaries....so i was wondering ya'lls input on

the power potential of a three rotor with high compression rotors, bridge port, ITB's

and race gas? this will be a track only car so any other input on na performance

would be great. thanks guys! rotor on!

400+bhp is a very realistic estimate.

That's actually being conservative. N/a twin-rotors are making well over 350hp at the flywheel with J-ports.

judge ito is running 305 rwhp in his rx3 with a big bridge 13b.So a 20b could be left up to the imagination or a very good builder.....hannover can hit 250 bhp in a 12a with a bridge.I have not built very many rotaries and was at 225 on a half bridge 6 port in my first gen.20b full bridge =allot of potential.
