hey ppl, after watching the top gear episode about the bugatti veyron I was wondering what it would take to couple two NA 26B engines together in a car and get a 1000 hp car without the need for 4 turbochargers. Gas mileage aside I think it'd kick *** and sound oh so sweet. anyone think it could be done?

and another question, it seems that all the mazda rotary engines I've seen are of the 600cc displacement for each rotor. is there a reason for the rotors being this size, as in are they an optimum size? I know that engines with more than 2 rotors are a lot more complicated than any 2 rotor engine but I was wondering if you could make the rotors smaller and with more of them as they do with V-12 engines, just to make the engine smoother (as if it's not smooth enough)

 

A 26B redlined at 10,000 rpm is allready making around 900. No turbos needed, and that's *one* 26B. They de-tuned (lowered redline to 9000 rpm) for the Le Mans race to ensure longevity. Turns out they coulda ran it at 10k, and it woulda been fine.

 

you're right about that miss and made a good point

But... that engine was also race tuned and would probably be impossible to drive on the street i.e. not made for stop and go, and tune it up to 10,000 rpm redline and you have an engine that is still fine for racing, but that engine has to last at least 150,000 miles in a street car, which it probably wouldn't.

 

How long is Le Mans, 5000km? If you can run an engine between 6000-9000rpm for 24 hours, I believe it'd last a longgg time on the street, of course another major concern is the engine's drivability below 6000rpm, with peripheral intake and exhaust, oh and also emission haha. But just to get my point across, 5000km on the race track = a lot of street miles !!

Don't think drivability is as bad as you think, if you can afford the engine I think you can tune it for street mode also.

 

I was thinking about this the other day actually. A mid engined, 4-rotor supecar. I would handle like a dream and haul *** like no other rotary. Price is no biggie cuz its a supercar. Mazda should go all out, carbon fiber and all that fun stuff. Like a street legal 787b! That would put mazda in awsome competition with the new NSX and LF-A supercars. Not to mention the awsome publicity of the image of that car would put on the mazda name.

 

I'd like to see that as much as you but it's not based in reality. 720 is the most I've ever heard of.

 

From wikipedia:

Offical is "over 700hp"

"Engine speed (RPM's) were deliberately kept low for longevity under the extreme stresses incurred during a 24-hour automobile endurance race. The 787B was reported to have a redline around 9000rpm. However, interviews with Mazda's 787B race engineers revealed that the power of the quad-rotor increased dramatically above 9000rpm. One engineer stated that the car could develop more than 930hp with a redline around 10,500rpm. Engineers also commented that during the post-race inspection and tear-down of the quad-rotor engine they discovered that all aspects of the engine were still in excellent condition and could have run another 24-hour race. This is a polarizing testament to the reliability and performance of the the modern Wankel rotary engine."

This is the only place I've found the 900+hp claim, it is debatable, I myself however think that the R26B is capable, just increase the rpm the hp should increase because the engine should have no problem flowing the extra air needed with peripheral intake/exhaust.

900 seems a lot..... NA power.... wow... beats F1 engines..... but probably 2or 3 times the weight...
