I have came up with a port but don't know if its going to work, don't have a drawing or anything to show but u will have to think about it, well its a 13B 4 port on the side plate the port remains the same, now adding a monster port without crossing the O ring line so when i put the housing on it u will never see the monster port, not to put a hole the size of the stock exhaust or little holes (almost like a PP port ) where the monster port is,...... now what do you people think preferred pros if there is any in this forum???? is it going to work and i haven't figured out weather i am going to open or close late on it...... thanks for the help no B/S please

so basically a port in the water jacket? so like a PP fed frm the side ports via the rotor housing? The only thing i would think that could be goof for was cheating in a racing class that doesnt alow PP's or something. It would flow less than a true PP , most likly ingest some coolent no mater how much rtv you used and have all the down sides of a PP without the same power,..

you got it drago like a PP port but not a Full PP port but the water jacket is not gonna be working, also i know there is guys out there that has custom ports cuz i dont think im the only guy to come up with this idea and if i am then Jim Mederer from Racing Beat better hire me on his team gimme a hug Jimmy ol Boy

i need proof, and i have alot more ideas but its costing time and main thing money to do it

Heck, I'm not even allowed to see it. I just know its there and makes more HP than a big bridge. 170ish RWHP on a 12A with a Nikki.





(And I know that is a lame answer, but I cannot divulge any more)

Uhhh you should wait to see how well it works before you make a claim to fame, there, buddy..

bill shurvinton

Doesn't really have a name. Its an engine FFS.



Nothing is really new, everything has been tried, sometimes published, sometimes kept secret, often by Mazda engineers. Probably before Master dren was born.



But think about topologies. If you make a big PP eventually you need more support for the apex seal as it passes over. So you put a bridge in the middle of the rotor housing (something being tried by Guru racing according to an article on their website) so effectively have 2 PPs on the same housing.
