I got into an argument with my brother about what engine is better: rotary engines or piston engines (since he has an s14 and i have NOTHING). PLEASE tell me some advantages rotary engines have that piston engines don't so i can **** him off.
And yeah i couldn't search because the search engine is down. HA

more horse power per liter

the smoothness of the rotary engine that no piston engines can match...

Yup! A 5.0 litre piston, comon mustang, puts out 265 or something like that, and the rotary turbo 1.3 litre puts out 255 and STILL smokes a GT!

high exhaust temperatures and the overall hot running characteristics of the rotary help spool turbos better. Huge hp from an extremely small engine, making it possible to keep the weight close to the center of the car, giving a front/mid-engine lay out, which gives the rx7 legendary handling and a perfect 50/50 weight distribution. Best bang-for-your-buck when it comes to higher hp...no moving parts to upgrade, unlike a piston engine which has many that need to be upgraded (understandingly so when you consider how everything's being thrown around!). the stock motor can handle as much hp as you can get out of it with proper tuning...a streetport is about 250 bucks and will give you %15-20 more power, bridgeporting is about $350 and will give you even more, but is not street legal.

If you need proof that the rotary engine is the best engine ever created (other than F1 I'd say) then just take a look at 1991 when Mazda developed a rotary race car to compete in the Le Mans 24hour race. Not only did it totally devestate the feild crossing the line 3 hours before any other car...It was banned from any future races! On top of that...the motor was torn apart and could have run another 24hours!! ahh...I digress, the 787B will never be beaten!!

lets not forget about the weight difference to, but also a rotary engine can out rev most piston engines.
i have to say i also get into arguments with friends about how rotary engines are good, its an on goin thing lol

rx7raca

wow that is some great info, why was it banned?

the electric call will rule over all

Rotarx

Cause the Lemans guys thought that the Rotary had to big an advantage over all the other piston engine powered cars.

twint78

you can not describe a turbo motor vs. a n/a motor.this is like apples and oranges.

now describe similarities of the 13b renesis 250hp 1.3l vs a 265hp 5.0.then again which one is about maxed out.the 1.3l.

that small displacement argument is a small ***** argument.

ur advantages are

smoothness.

ability to get away with staying on the throttle a little to long high up in the rpm range.

not the exhuast sound,but the engine sound it makes when it is rotating at 7500 rpms.sounds like it is about to take off as a jumbo jet.very intimidating at a drag race with a 2 step.

This is true!

Rotary engines look much cooler when your hood is up than piston engines. Girls will migrate over to one while they walk past every piston car in your row. Happens all the time at the drag strip.

Michael Eng

hahaha even better

BoostedRex

Also, just the sheer rareness of it. Not that many people have 7's compared to the countless minions of the piston engine world. And as many others have commented the smoothness is the only argument you need to make. Not that any of the others aren't as important, it's just unheard of with any other engine design ever that you could be at redline and still have virtually no engine vibration at the steering wheel. I will never go back to a piston engine for performance the rest of my life. Laterz.

stock 5.0 in mustang=225hp...not 265.....lol..

MichRX7

Or in laymen's terms... At least 10 car lengths behind me in the quarter mile.

Contrary to poplular belief, NA rotary engines are more reliable than equally powerd piston engines. The fewer moving parts along with the constant one way directional rotation of the engine contribute to this. Just look at the many NA rotaries that are pushing 300k+ miles, and still going strong.

Jim Calandrella

First of all, I love my 7. Lets just get that out of the way. Ok.
Now, they are absolutely apples and oranges. The 5.0 puts out 225 hp, which is a little low. But, where the 5.0 motor gets it's revenge is in it's ease to modify it. Also the price for parts is a lot cheaper that stuff for the 7. $1,500 into a 5.0 will get you somewhere(and maybe above) the 300 hp mark. $1,500 won't do that in a 7. Now, I know that there is a weight diffirence in V8 cars as well, so i'm not saying that even with that $1,500 put into the car, that it could beat a stock or a little above stock 7. I really don't think it would. We're just talking engines here, not the car that they're in.
Piston engines are also on the whole more reliable than the rotary is. Now, my 7 is reallt reliable right now, but it wasn't always. I know a lot of people here have great reliable cars, but i'm talking generally.
Basically, all the great points about the rotary are true: weight, smoothness, etc. A good running rotary is truly spectacular.
But the piston engine is still a great thing. LS1's, old 5.0's, 350's(which liven up tremendously with the simple addition of a cam), 383's, 454's, blah blah blah, are all great engines.
I don't truly believe one to be superior. We're just talking engines remember, not cars. The rotary's power to weight ratio enables near untouchable handling, and furious acceleration. But the piston engine has time and time again proven it's worth.
I agree with the 787 B remark though. That car was unfucking believable.

GentlemenVII

Two words...
POWER OVERLAP!!!!!!!!

a I4 has none there is never more than two pistons at TDC(top dead center) one being a power stroke a Rotary has an infinate Power overlap, also less moving parts(plus no violant change in direction of this movement) smoother, higher RPM's = Kw/HP, well The Rotary is just GOD!!!!!!!!

If we're just talking about the rotary engine, then another side note would be now-defunct British motorcycle manufacturer Norton, whose owners licensed rights to build a rotary engine for their top-of-the-line "sportbike" (it never made it into production) back in the late 80's. They built a few one-off racebikes to run at the famed Isle of Man TT, a race run on the streets of an island in the middle of the Irish Sea (the course is 37.7 miles long). In the 1990 race, with literally no R&D on the chassis, one of the Norton rotaries finished second in the feature Senior TT race, while all three finished in the top ten in the Formula One race (one finished third). It was reported that the Norton rotaries had top speed and acceleration over all the other bikes by a long shot, but the handling bugs weren't fully sorted out, so their overall race performance suffered. The rider who won the race said that he couldn't believe how fast the rotary Nortons were. This, mind you, was against the latest racing motorcycles of the time, with several factory works machines in attendance. The rotaries were outlawed from the Isle of Man TT afterward as well.

Oh yeah, one more thing: it wasn't so much that the 787B was banned from the 24 Hrs of Le Mans, the organizers were trying to keep speeds down, so they limited the entries for the following year to 3.5L engines. Arguments arose as to how to calculate the total displacement of the rotaries, which, in the end, was the beginning of their ban/handicap in car racing(and in other series as well).

Thus endeth the rotary trivia essay for today...

MichRX7

Damn...

Now I want a rotorcycle as well...

Chronos

arguments on handicaps....BULL ****!! They needed an excuse to ban that totally outclassing MONSTER racing machine so they could still sell their pissed-on-engines!!

Have any of you ever seen the 787B in action??? I have an EXCELLENT video on my FTP server that I hope all of you guys watch. I can't even relay to you in words how incredibly ECSTATIC I was when I first say it!!!
