powerful, high-revving, n/a rotary engine
Hi guys
I have no project, I'm not gonna build anything, I just wanna ask you this for learning\information for building a powerful, high-revving, naturally aspirated rotary engine what is the best starting point (12/13/20b?) what are the best thing to do to the engine? what would you do? thanks :) |
id love to own a 20B n/a. Reliable 350rwhp. Thats all i have to say about that..
|
wow, that much power from a 20b without turbo? interesting. on what type porting?
|
350 rwhp n/a 20b's are not common by any means, not yet anyway. We are working on changing that as more people see what is possible through the R+D we are doing. A lot more power can be made though, I have dyno'd at 428rwhp n/a. Here is a link for info-

best for what? Power? money? Obviously the bigger engine will be best if all out power is the goal (20B). It's a good bit more expensive than a two rotor.
Barring that (or in most cases including that) the ultimate N/A engine is just like any other engine: highflow, light components. so P-port. Well designed intake/exhaust, S5 na or RX8 rotors, RPM mods, etc. Big N/A ports don't typically street well. All that said, I have a dream check list for cars/motorcycles I will own before I shove off. An N/A 20B is high on the list, but not soon. |
for all around streetability a good 13b 6 port racing beat intake and a good side draft carb like dellorto as well as a header and free flow exhaust will do the trick. if you want to have more do a street port on the engine first, but remember when you start porting for more power the streetability and daily drivability start to deminish. Just find a 13b, carb it well with good exhaust, and take it to 8500 it will work good for ya.
just my .02 worth but been working for me. Joe |

streetport here too, and driven every single day. |
Snivley your view on streetability would apply to those who rely on their 7asa daily driver. For some streetable means it can be run off of pump gas.
|
Even though it's in a relatively heavy chassis, you're not going to beat a Renesis for streetable power and a broad (by n/a rotary standards) torque curve.
