This is the thread for all those rotary engine lovers out there. Post pics of your rotary-engined car or ask questions about them.


Personally, I'm a huge fan of 86-91 rx7s, and Im working on acqiring one.

Hey, look what I just found, It's a free downloadable rotary simulator, and you can make custom ones. Its pretty fun to mess with.

So, I'm not familiar with rotaries. What exactly is 'rotary?' What rotates, what sets it apart? Pros, cons?
#17
I have a former co-worker of some sorts whom probably was in the neighborhood of 100 rotary blocks in his shop. Everything from 12A's all the way up to various 3 rotors and 4 rotors. I love the way they sound for sure, nothing but love here.

Wankel rotary engines are more powerful then piston engines, but use more gas



i wouldn't say more powerful.

plus there apex seals always fail where as a piston rings last soooooo much longer

it really depends on how many cylinders you compare it to

but damn do they love to wind lol.

I knew Mazda used them a lot, but I didn't get what was special. Thanks.

Basically instead of the up-and-down motion of a piston engine, which requires a lot of force to convert the combustion motion into torque, the engine's natural movement is to rotate, which means that the torque is direct. The piston engine has to start and stop and start and stop twice per rev, and the rotary just spins...

13B-REW's and 20B's are pretty righteous, but I still like my regular Combustions.

For a daily driver, especially in the winter, I prefer something with a simple piston engine... but when it comes to actually enjoying the drive, it has to be a rotary. I'm obsessed.

Good explanation man. Most folks that understand it can't explain it that well. You done good.
I still prefer a radial engine myself. God I love the sound.

They are alright, I guess. As long as everything is balanced, knife-edged, etc, you can rev them up to as far as you want. Major pro is being able to wind your gear out to how tall it actually is. Id rather work on my 4 strokes though.

Rotaries suck ass. They are too damn tempermental. First of all, there are too many intricacies of rotaries. You cant over heat them at all, and they push out way more heat then piston engines. The are designed to burn oil. The horsepower rating on the older ones is sh*t. The only thing that gives them any bit of coolness is the torque band. The older designs of the rotaries that were in the 2nd Gen RX's were severely flawed. The were too heavy and had too many parts that werent required for operation, such as the OMP pump. That was the dumbest way to sucker people out of money when they broke down.

Personally I hate rotaries, just because I have had to rebuild one. But other then that, I love RX-7's. lol

i had an old 86 rx-7, the engine was ****ing awesome but the car itself was a death trap (really bad shape)

ive heard of dune buggies liking rotary engines due to thier great power to weight ratio

I agree with the first two but it is not more fuel efficient than other 1.3L cars out there. Granted those other cars dont make 240hp N/A, The design is ingenious, gotta love down shifting and hitting the powerband at like 7K.
