Mr Pilkington

Has anyone here ever been brave enough to do yon upgrade to 10A (4 rotor)? Or for that matter the ever rare, and even more powerful 21A? (FC only please!) I ran across these monsters while doing research on a supercharger for my prospect 20B upgrade, and was just interested in seeing other peoples work in motion. I haven?t been able to find a 21A installed; but a few pictures of assembled models, working without actual install. And the only working 10A I found in an FC was in drag car with twin turbo. Post your pics or possible mods!

um i thought the 10a was the 996cc engine used in old rotary vehicles like the R100. I'm pretty sure the 10a is not a 4 rotor. There is the 26G and the 26B (4 13b rotors) but i've never heard of a 1.0 liter 4 rotor!

Sounds bogus, I have never heard of either of those engines. I would re-examine your sources.

I think he may be refereing to what would be called a 20A I've seen pictures of one but thats it.

10A is a small two rotor from the old RX100 (RX1)
And the 21A was an experimental engine from back in 1972.

Perhaps you are confusing the 20B and 26B/G, as the 20B is a 3 rotor, and the 26B and 26G are 4 rotors made for racing only.

Here is one list for Rotary Engines don't know if you even care, http://www.monito.com/wankel/engines.html. Interesting read regardless.

The 10A wasn't a four rotor, but there was a 4 rotor containing a 10A it was the 2002 engine. It was made in 1971 and it was rated at 180bhp, it was made by joining two 10A's with a Curvic Coupling.

Three separate fan-sites say the 10A was 4 rotor AS WELL AS the 26G. Not to say they are right, which is why I ask. I see footage of a 4 rotor FD, and have pics here of a twin turbo 4 rotor FC (However now that look the drag car it says 26B 4 rotor.) Also here is the 4 rotor used in the Le Mans race. It wouldn't too tough for many of you with the technical prowess to build a 4 rotor. But the 21A I am aware was experimental. However lets face it, that never stopped anyone before. I see a couple of fan sites claiming to have pieces therefore wondered is anyone had the brass to actually run one. A mere inquiry.

IceMark is never wrong.

Icemark

It is amazing the number of "fan" sites that do not have correct information posted. I know of three that list the GTUs having a "turbo" tranny, when the R-type (turbo) tranny was never used in a GTU or GTUs model.

Any site saying the 10A was a 4 rotor, I would avoid like a computer virus. For if they have something that simple wrong... well what else would they have wrong.

ah when the 20B was created it was radically better than the 21A, The 21A was simply an experiment that never left the proving grounds (unlike the 20B or 26B/26G, both of which were produced for racing, and the 20B was also available in street cars (infact there was talk back in 88 of the S5 coming standard on the top line models with the 20B).

Icemark

Now that is not quite true... Kevin corrected me just last week on rotor weights

Swolbynos

notice that it says 26B?

Mr Pilkington

We all have our moments, more off than on in my case but... meh







I just need to have you come teach me this car inside and out. Too bad I can barely afford my own time let alone a pro's. And the tickets to get down here... then again I could set up a Fed Ex.... how many air holes do you need? Or I could learn the way I learned the 350! "Hmmmmmm This bolt looks important. I guess that's the noise I've been hearing the past couple of months."

4 Rotor engine as in the engine that was in the 787B????? Where do you get one of those? I didn't know that was a production engine.

mz-n10

um....is it just me or is the 4 rotor fc really a 4 rotor bmw 3 series?

PureSephiroth

well i don't know if its a bmw but it definately is no RX-7!

Tessai

Yup, IIRC the car was originally a 323i, but I am not sure... it is deffinately a 3-series Bimmer though.
