Hi! Jerry
Thank you for the information, I was under the impression that P-ports were a established & proven system.
I think that until it is I will stick to street porting (200hp) is what I require 7 should be able to get close with proper inlet & exhaust. Once you have things worked out I'd be interested in building another engine with P-porting. Please keep me posted.
Regards.

Hi George, you are right, you can handle boring of the rotor
housings. It can be done with a hole saw or a boring bar. Location
of the port is critical as is the size: Intake opening and closing
events are determined by these two in combination. I can give you the
information you need. Now, comes the harder part. If you want to
install the butterfly as close to the rotor as possible (which is
recommended), you will have to build a throttle body that is inserted
into the port you have just drilled. I can supply fairly complete
drawings for this but it is not an easy build. I worked with a local
machine shop to produce mine and they did a first class job. They
would like to do more. Lastly, the intake manifold, most specifically
location of the injectors, is another issue yet to be solved and
proven. The good news is that we have one option that we are confident
will work, so if plan A does not make us happy, then plan B will. More
good news is that once we get the intake built and proven, Ed Klepeis
will be able to supply them. I am working on the intake at this time.
I am not going to provide any p port stuff until we can guarantee the
performance. However, if you are talking about 7500 rpm then you can
expect 250 hp. My engine will be limited to 6000 rpm and should
produce 215/220 hp. Regards, Jerry
