How much HP will the 13B twin turbo put out without the turbos and can
they be P ported?

With decent porting, high compression rotors and at about 7500 RPM
close to 200 HP.  Yes they can be p-ported.  P-port HP about 250.

Paul,
    I'm Tim and have been tuned in for about a month.  I've been very
impressed with the diversity, quality and quantity of information being
shared.
My question is, has anyone successfully put a rotary in a BD-5?

That's the little one right? People have fooled around with
a one rotor in BD5's but it is a bit heavy for the HP until someone
comes up with aluminum end housings. The two rotor would be way
too heavy.
