That's an oldie, so it probably is a repost, but freaking 99.9% of the stuff I post is a repost...so I'll just shut up. :wink:

Isn't the 20b the 4 rotor motor? :?:

Re: Three Rotor AE86
 

LOL and yes it is a repost....

No...it's a 3-rotor, the number in the designation of each rotary engine is a characterization of its displacement. Hence, the RX7's engine was a 13B (1.3L). The 20B (2.0L) was available in the Eunos Cosmo in Japan in the '80's and early '90's. Each rotary chamber is a bit under 700cc, so if you think about it when you have a two-rotor you get around 1.3L, for a 3 rotor, you get about 2.0L, and for a 4-rotor (which as yet has only been available in the Mazda LM cars, or as an aftermarket concoction) would be a 2.6L.

No its the three rotor sequential twin turbo out of the cosmo

that thing was fast as hell though.. heh,just flew off, good to see it again..

i seen the video, but i'm still wondering where it came from. what it from an Option2 video or BM hotversion?

-Without the sequential turbos.

My god what an annoying video.

actually they are sequential

Thanks Vansquish, very educational.

Another question, does anyone know what Mazda rotary car had the Dynamic Supercharging System, and how much psi does it produce? :?:

i don't know of any mazda rotary engine with a supercharger, but i know of a mazda with a miller cycle engine with a supercharger

A Dynamic Supercharging System doesn't use a Turbo or Supercharger, this is something unique of the wankel motor. It uses pressure waves generated inside the intake tracts by the sudden opening and closing of the ports using a Dynamic Chamber.

But still, does anyone know what Mazda rotary car had the Dynamic Supercharging System, and how much psi does it produce?
