A Rotary won Le Mans against 7.4 litre V12 Jaguars and 5.0 V8 Turbo Sauber Mercs.  And Three Rotor N/A RX8s have been competing at the Daytona 24 hour for the last 6 years against V8 Corvettes and Porsche 911s so torque\'s not necessary for endurance racing.  

The torque is useful here because you\'re turning four wheels and running on both tarmac and mud, on mud you\'re working to get the car through the mud so more torque is useful.

Apparently putting details of your car spec in your signature means the nice folks on exile-rotorsport think you\'re a fool.  I can think of no higher compliment!

All technical gunf aside.......that car is a rocket!!

Midrange torque isnt a big deal on a racetrack at race speeds providing it has the gearing to stay in the powerband. You\'ll rarely ever see the rpms to need it.
 
But its vital where things go slow fast slow. Road, sprint, rally, drift, etc etc, no matter how good a driver you think you are, and no matter what your gear ratios are.
 
Get in a rotary with a quick spooling turbo and a good boost controller. Drive it once with it running 0.8bar all the way through the rev range. Drive it again where the boost peaks at 1.5bar and slowly tails off to 0.8bar by peak power rpm, so exactly the same peak power level.
Then tell me the difference in real world performance.

Well, my opinion is that torque is needed. :)

Our supercar rules dont allow to use rotary engines at the moment. But we will try to change it some day. After all, we managed to change rules in autocross class, so original displacement rotaries can be used.

I did talk with driver of that RX in last summer. Car was very new, they have just finished it. They had some minor problems with it, but other than that, its going just nicely. Like because of that 4wd drivesystem, he cant use handbrake in turns. But ill bet  that all those minor problems are gone now. Looking forward to see it run in next season! :)
Power is nothing without control. Weight is enemy of performance, handling and braking.

What Grant Said about the technical aspects however that man is about as malignant and electronically aggressive as you\'ll find on the internet.  Probably the only reason he\'s not been banned from that forum is that he owns it.
