Peripheral ports- ideas/pictures
There is more than one way to cook a chicken and more than one way to make a peripheral port. What are some of the things you have seen and/or tried? Pictures are even better. Carb types, throttle bodies, etc.
Anybody out there ever tried perpheral ports as secondaries on a street (wink-wink) engine.
I have seen some interesting stories of sliding throttle mechanisms and telescopic ports.
Show and tell.

man you are really going all out on some of these projects. it's nice to see some people go away from the norm. even if it doens't work you might get ideas for somehting else. i don't really have anyhting but try talking to rob @pineapple racing. that guy knows his **** and has built every kind of rotary there is. he is also a cool guy just to bullshit with

This is an area that people have really spent a lot of time on. When I start resurfacing housings for others I will probably see some wild things come in. I'm sure that alot of people will not want pictures of their porting posted. You have to honor that. But here people that are will to show their work off can give us a view of their creativity.

A peripheral port is cut into the periphery (hence the name) of the rotor housing and not in the end housings. The exhaust ports are peripheral ports. The standard intake ports are side ports. Peripheral ports are open for a longer duration and flow much better. They are fantastic for high rpm use. The downside is that they have zero low-mid range power, and have a very high idle. A peripheral port also need little to no muffling of the exhaust to work good. There is also a very high amount of port overlap which dilutes the incoming air with exhaust gasses at lower rpms. This is what contributes to the poor low end. Great for race use but unusable for street use unless you are an Australian! Gotta love those guys. Naturally aspirated peripheral port engines can get up to about 350hp but they have to send the redline sky high to do it.

As for the side port, you can't quite tell in the pic but it's obviously been filled in.

There is definately a story behind that. There is just too much nice work on that motor for the cardboard to be passed as part of the finished work.
It is a nice looking motor.

why's the side port still there?

With the e shaft out of it it was not being assembled at this poiny obviously. Maybe the plenum was being worked out. Cardboard makes for good modeling material.
