this is so great, I hope there will be a video of it running soon.

It looks so nice to, you spent some time on this one.

@RedStaryPuu Yes, but in this video, it is a Mazda 20B, not a foreign engine of some kind. If the Russian engines are of poor quality, why bother with them when doing a conversion? The Mazda 20B in this video is very reliable and doesn't have balance problems. Then a larger multi-rotor (5+ rotors) from any manufacturer is going to have the same issues just due to its length. Look at the Mazda 4 rotor: they have a bearing at every iron due to shaft length.

@aaroncake true but that dos not mean evry one makes wankels to mazdas standerds , mazda makes rly good wankels i deal with wankels evry once in a while but there not from mazdas there from russian vehicles and tripels over around here in the balkans "im Albanian" rattel alot and 2 and 4 seem to be fine russians if you did not know made quite a bit of stuff with wankels in them and still make lots of replacement parts

[aaroncake]

So here's part 1 posted 3 years ago...Any more parts?

[aaroncake]

@RedStaryPuu This is a production Mazda engine, the 20B. There are no balancing issues. And it's not exactly trivial to build a 4 (or 6, or 8) rotor either. Large rotor count engines (and there have been very few, mostly prototypes) carry their own problems like eccentric shaft flex and lack of torsional ridgitity.

@Gavinlance Easy answer: 20B Vintage Cosmo.

god they are one ugly car

uneven numbers of rotors seem to have lots of problems balancing problems mainly at lest from i noticed so id just stik with pairs of 2 4 if your even crazyer and what far past 1500hp you could go to 6 .... maby even 8
