Everyone knows that Mazda won Le Mans with a 4 rotor race car, but with the new MSPRE design, many have discussed that even a triple rotor would not be a simple task for routing of the intake and exhaust ports.

I have had this idea for a while now, but haven't really heard anyone else mention it. How about 2 RENESIS running in parallel with some kind of gear box that would combine the power of the two. In RX-8 form we know that the RENESIS will be able to produce 250HP, 280HP in prototype models. Many are speculating that the larger rotor RX-7 replacement could produce 330HP.

Let's take the larger RX-7 power (330HP) x2 and multiply some fudge factor for race tuning, race fuel and all disregard for emissions and noise, say 50% increase in power. That would make it 990HP. Even without the race tuning fudge factor, a 660HP twin motor, twin rotor Le Mans racer would be competitive.

What are your thoughts?

 

The FIA won't allow 2 engines in one car.

 

A somewhat broad statement that isn't universally true. There are several instances of twin-engined cars competing in the likes of the British Hillclimb Championship, for example.

What I suspect you meant was that twin-engined vehicles are banned in the FIA Sports Car regulations. That I'll grant you, but doesn't the Automobile Club de l'Ouest make up their own rules for Le Mans anyway? I seem to recall that there have been disparities in the past between the FIA and ACO regs.

 

isnt the rotary engine banned from such events as le mans?

nope, one ran last year in the LP675 class... it was a modded, and detuned R26B model, and lost most of the goodies which made that engine so freakin' incredible.

on that note though max, i don't think that Mazda would really keep the side exhaust ports unless absolutely forced to by the regulations, and the same goes for the intake ports: it's no secret that perhipheral porting is easily the best way to make tons of power...
realistically, i don't see how two motors in parallel is somehow better than just a quad rotor motor... i really don't think they'd so anything like that.
if a serious challenge was going to be made at La Cirque de la Sarte again, Mazda would certainly be developping a motor incorperating a lot of the technologies incorporated in the R26B design... and maybe a concept for more efficient expiration?? anyhoo, possibly one of the best all-motor race engines around that circuit ever, the R26B...
