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!

I don't know about a bridge port but I've been told that 450 hp is possible with a peripheral port. I'll be sure to let everyone know when I get mine dynoed.

Pport is the way to go. Basically, it's just changing rotor housings.

A decent BP will produce very simliar power to a PP and will be much cheaper.

PP you will need, custom manifold, New rotor Housings, end plates filled, prob not such a good idea seeing as though you cannot buy centre plates anymore.

Should be able to get 450-500 out of a well sorted 20B BP

They are getting over 350hp (flywheel) out of twin rotor BPs here, add an extra half a motor..

Having run a BP as a daily for 10 years before the 20B I'd say go the BP

BPs sound the same.
