  • 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?

  • @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

  • Its for the corner seal, not apex seal.

  • 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.

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

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

    what do they mean anyway???

  • 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..

  • lol yeh tru does sound like a boat

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