3-Rotor engines available...
Well, this is a step in the right direction. Please take a look at this post:
http://www.grandamerican.com/Message...ad.asp?ID=1017 This means Mazda has homologated the engine, and it is available to anyone (of course racers will be making most of the purchase). Mazda only has to make a certain number of engines. I don't know how many units exactly. Will it be the old 20B design or will it be based off the Renesis design? I thought you would all like to see this. Could this be a sign of things to come for the future RX-8? I posted this here initially for all to see, but think it belongs in the Racing section at some point. |
Thanks for the link, I had a good time reading the racing regs....is that weird :confused:

I hear that rotary engines are modular, or stackable. This is very costly, which explains why purchasing a 20B costs an arm and a leg. I don't think Mazda wants to dump money into designing a new 3-rotor engine. Besides, I have often thought of the extreme heat transfer occuring in the middle rotor, not to mention the horrible gas mileage and poor thermal efficiency (as if a Wankel doesn't have a bad one :( ). I hope a production 3-rotor never makes it. It's not worth it. I would rather prefer to increase the rotor width by 10 mm to get a 16B.

I think a 3-rotor could be wanted by the exprimental aircraft people,
the old 20B is used already by them. More on www.rotaryaviation.com |

what??? 20B's cost an arm and a leg because there is only a limited supply of them. How many Eunos Cosmo 20B's were manufactured? find that number and you have a pretty good idea of almost exactly how many production 20B's made it to the real world. from what i understand the number is in the 1500 range... that's not very many.
