well the debate turned into him saying:



Like I said, make all the excuses you want to glorify it. If it were a better design, more companies would be using it.



Even GM tinkered with making a rotary-powered Corvette many years ago. Thank god that idea never made it to production.

I've got the 3.8 V6. everyone on the Taurus/Sable board says they are lucky to get to 250 with their 3.8's

ahh .. makes sense now.. she has the 3.0... your sable the equivalent of the taurus sho ?

Not that I know of. if I'm not mistaken the 3.8 was just an option they offered, but they are known for faulty head gaskets and like all other merc/fords, shitty auto transmission.



its still fat, heavy, and handles like ****. But it is good enough to cruise around on weekends with friends, take on trips (where it lacks in gas milage it makes up on shitload of room). It gets me through traffic fine and can hang pretty good on the Hwy.

the downfall of the rotary is that

1. it traps some unburned fuel on the trailing side of the rotor

2. the surface to volume ratio of the chamber is such that the rotary puts a lot more heat into the water and oil per hp

Gm bailed because they could not figure out how to pass emissons. Their 1st rotary car was supposed to be the Monza in 1974. The EPA fixed that one. GM panicked and bailed on the engine all together.



When Wankel was selling his patent rights to other companies quite a few bought them. Back then it was a bargain to buy it because it was not a production proven engine. Mazda proved it can work in production.



Imagine how much it costs now.



I am gald no other company came out with a Rotary. Makes our cars so much more unique.

i think if someone else had a rotary, it would be a lot more mainstream, it wouldnt be so weird?

FD3S DRIFT 12-13-2003 07:01 PM

more bang for the buck, and since its so light better chassis dynamics.

also pistons haveto stop at the top and bottom and that doesnt make any sense to me. also less moving parts.

Id rather see it as unique rather than weird, thats mainly the reason I don't even feel like selling my FC because its not like all the others....... its different https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Just to be devils advocate:



The downfalls of the rotary are not so bad. The Renesis engine has zero exhaust/intake overlap so there is no unburnt fuel in the fresh air charge.



And the rotary makes more HP per POUND or per liter of displacement than a reciprocating piston engine. Those may be a couple of the more tolerable reasons why the rotary add more heat to oil and water.



If FORD did not control so much of Mazda we would see more advances in rotaries than imaginable...
