hayward rotary 20b peripheral port

[22ness0hayden]

4 years old this vid and haven't seen the car since the old school meet in 2007. I can only assume it was shelved?

[johgurette]

what is the difference between bridge and periphial port?????

what do they mean anyway???

Instead of the side ports there's a port going through the rotor housing. Much bigger.

[TakadaGenbe]

normal rotary engines run a swept side facing port for intaking the air/fuel mix, the periperhal port is a large port thats moved off the face and is bored into the housing like the exhaust port. it allows for MUCH more air to move into the engine. a Bridgeport is where the side port is extended out with a "bridge" that allows the apex seal to ride on so it wont fall into the port and snap.

Its for the corner seal, not apex seal.

Wow that idle is street worthy. I've thought about building at PP for years but thought the idle would need to hover around 1300rpm. This gives me hope.

20b w/ peri.ports would be a great setup.. and this is a very nice setup you have.. but it sounds weird..

[TynanMaaka]

lol yeh tru does sound like a boat

[porkblapper]

dont get me wrong i am a rotary/mazda fan, just teh tri rotor pp sounds really jetski like

[ADHD20B]

@porkblapper thats because its a piss poor quality video and shit sound. 20B PP's sound probably the best, nothin like a jetski. though i take it that was a first startup and needed tuning too so yeah

[thunkrd]

where are you located

[rotarymiata]

what type of ignition system did you use.

[mazdamadrx4]

I tend to agree, this is built for desimation, love to see this in full song around the track.

I have only one gripe and thats Hayward rotary's email address on their website.. it doesn't work... so much for bringing in potential business.

[rotaryenthusiast]

that would destroy
