Who here has a race/peripheral ported 1st gen? I know mine is race ported, it just doesn't fire up and i wanna hear one. Post some vid clips or sound.

lmao, epic^^^
How did you do that? |
|
ive seen like 3-5 vids on youtube with a peripheral ported 12a, and not too many are good. i just thought that there wuld be a whole bunch of ppl on here with a first gen 12a peripheral port and they wuld have vids of it.

WTF is a "race port" anyway? I see people saying that all the time, but I have no idea what it's supposed to mean. Bridgeport? Peripheral port? Large streetport?
|
beautiful response!!
|
it's a port, but larger than a bridgeport. u have lower torque from 1000 rpms to like 4500/5000 rpms untill the other 2 valves open to let more air into the engine, thats when the torque kicks in and u can hear the difference in the engine, watch some vids and when they hit 5000 rpms, u can hear the change, its sik.

Still trying to figure out what you're talking about. Sounds like you're describing the secondary butterflies of a progressive throttle body, or maybe the auxiliary ports of a 6-port engine. "Larger than a bridgeport"? Maybe you mean a J-bridge?

a peripheral port is bigger than a streetport or bridge port, correct? heres a vid of what they sound like. http://www.youtube.com/watch?v=pXEMaw6ul04

That's just your everyday peripheral port engine. They have only one intake port per rotor (unless it's a semi-peripheral port, in which case the side ports are retained in combination with a smaller peripheral port).

Howdy boys.... a race port is any intake or exaust that is modified (opened up (street Port s are usually ground out to a open sooner , or usually made taller to allow the engine to suck more fuel longer before closing in or in the case of a bridge port, they drill and grind a eyebrow next to the original beside the original one so as to allow more fuel and air inside because it opens with larger port volume alot like a high performance cam does it keeps the fuel flowing longer before the PORT closes which increase s the amount of horsepower the car can make (remember you also have to pump up your fuel as well with larer injecters or more fuel pump volume and pressure to compensate for the increase in air you pull in with the larger ports ............street ports are done to create the best overall perfomance ,race and street then they use bridge ports, which also includes cutting into your water jackets which shortens the engines life and can create leaks, then when you don't need the car to idle around town or,try for gas mileage the serious racers go for huge ports cut into the face of the rotor housings about where your intake waterjacket is located they cut a hole into the rotor housing about 2.5 inchesas well as cut the same size for the exaust to exit. they also close the original intake ports of or fill them with devcon epoxy to seal them.but the larger the hole the less efficent the engine is at low speeds typical p (ports turn at8500 to 10,000 rpm but only really make high rpm power and are not usefull on the street so pick your race ports according to your typical useage for the engine pump your fuel up open up the exaust and beat the can of that rotary...good luck

thanks for the info on porting and stuff, all i know is that the guy before me said he had it raceported, but i wuld have to ask him the exact size of the hole and stuff, but what i wanna see/ hear a port that a racer wuld do, a large port or something like that.

What about a Rallye Port?
Or a Cheese Port? |
or the peninsula port?
|
aite...

2.5" wouldn't work on a 12a, I would love to see it rev just once (then spitting the apex's out)
