P-Ported engines are streetable. There is a R-100 12a with a P-Port in California. A P-Port would not last long at all, would suck up a **** load of gas, super ******* loud. But if you just racing it at the track, I would go with it. But if is gonna be a street driven car, I would do a 20b. A 20b N/A. That is just my .02 cents. There is somebody on this forum with a 20b FD. Name is Dragon. Look him up. CYM 20b FD.

Aren't peripheral ports loud as hell? Would that pass w/ the loudness?

Not with I am intending to do with it, besides any car is loud when you get on it. I will prolly run a few silencers on the street..



BTW where can I find some good audio/video clips of peripheral ported engine?

A P-Port 20b N/A.

Hmm I don't even know why you would want to do that. The P-port is really pointless unless your at the drag strip with the car. The 20b N/A would also be silly IMO. I mean you say it would be difficult to fit it but yet you go through all this trouble to figure out if you can rig the damn thing to do what you want. I am not saying that you shouldn't do it. I am saying that I know you won't. And rightfully so.

the problem with pports is none really has one thats streetable/quite, most of them are setup for the 1/4 or road racing. i am workign on haveign a streetable one so i shoudl know soon

it is possible to make a pp with sane port timing and thus sane idle/ low end

Maybe we can help each other out, what type of power and rpms are you looking at running?

Unless I missed something,



how loud a rotary is going to be has to do with the muffler system(s) involved, and almost nothing to do with the style of intake ports used.



There are a number of bridge ported engines running around and with little trouble or noise. It isn't easy, and one muffler is not enough, but it is being done.



The bridge port has much more overlap and intake opening time than a Pport, so the Pport is better at slow speeds than the bridge ported engine. That is not to say that it is a bag of fun at low speed, it just isn't as lame as the bridge port.



Both are poor off idle and can just pull the car along, not blast out of the hole. Getting to the false grid is just a bit easyer with the Pport. We just get it rolling about 5 MPH slipping the clutch, then drop the clutch and motor away slowly just off idle.



It is a long way from off idle to 6,500 RPM where any good power is starting to show. But you could drive it to the track and back, but I doubt if it would be much fun for either port style.



You might want to start with a big street port, but limit cutting much off the intake manifold side of the port. If that isn't enough, go back in later, and make it a full bridge port.

anyways.....goodluck with that project

its hard to guess what you want, even simple streetport coul dbe setup in so many ways that it will either make u want it or not. with pport its even more so. thre is much more to it then just the port, it sthe whole setup if you know what u are doing then i would say go ahead and do this.
