What type of problems usually occur with high horsepower 20B motors? What needs to be strenghened, what can be left alone?

 

the smartass answer: everything behind the motor

the rear answer: you are looking at the same things as a 13b. the rotor tips flexing, breaking dowel pins, getting the rotors to hit the side housings. the only additional things i can think of are, breaking the e shaft. and since the whole engine is more plates you have more chance of them moving around, on the 787b 4 rotor mazda used a big cf plate to keep the engine more stable. this is also why the 1st and second gen break dowel pins on the rear housing. the front is mounted to the car and the rear has to handle all of the power.

I was more curious as to bearings and Eshaft. I ws told that the stock Eshaft cant spin well past 8500 rpms and cant handle more than 1000 bhp.

 

That's what I've been told by several 3 rotor racers. If you want more, you need a custom EC from New Zealand.... my 2 cents..

 

i dunno about that, but it has an extra bearing, shouldnt that help?

I may be wrong here, but I think that Pepe Loco's new engine is running a stock EC... Ito, if you're out there, am I right? Or is this top secret
