Yeah I thought all this was already explained. It's not a 1.3l rotary engine, like the guy said, they call it as 1.3l, but in fact its 1.3 per rotor. Like no hook said, its 1.3 times 2 or 3. Those stats are bull, cuz if they were true then the RX8 would be able to beat the hell out of all those cars in a race, and, it can't.

And 88, what do you know about American muscle? If you want to take a true test start out with two stock cars, a v8 and an import, and if you invest the exact same $$ amounts the v8 would come out on top, why? Cuz your starting out with more power in the first place. You want to turbo your 4 or 6cyl? Fine, I'll turbo my V8. You want to do NOS? Ok let's go with NOS.

In the TOP GEAR episode where they feature the Corvette C6, they do say that the vette isn't made for handling liike the euro built cars are, and that's obvious. America doesn't at all have the same type of roads as Europe does, thats why we have cars that just all out all ass

[Haakon]

im just kiddin,its so fun v8's guys always trip iff you say they got a small penis!

in the usa im sure to have a v8 is kick ass but in norway many off the people that drives em are 40,work as truckers,have a mustash,cowboy hat and boots

dont see many of em in the rest of europe too!

NoHook the volume on each rotor is 650cc not 1.3L

[NickTheTurd]

LOL!! Very cool thread. Nice job, Nohook on making your point.

Haha, by rotard math, my car, a 2000 Trans Am with a couple mods makes 171.282 HP per liter, and even more Torque. At the rear wheels!! Wow!! Kinda cool. I think I'm gonna do rotard math from now on. lol

Anyway......joking aside......what is the big deal about HP per liter?? That doesn't mean shit. All that matters is how fast you can get down the track (or street.) Really!!

thank you, boyd. i got into this thread late, and all i could think of was the first years s2k. at 240hp out of a 2.0l, do the math any way you want. 120hp per liter or by nohook's brilliant math, only two cylinders firing for 240hp at one time=240hp per liter. oh, and naturally aspirated. i like the 13b rotary, but the s2k runs as tight as a sewing machine. wow, and i'm not really a honda guy anymore.

NickTheTurd, nohook is wrong, the volume on each roto is 650cc, therefore the whole rx7 engine really is 1.3L.

sry people but the theory about "firing rotors and not firing rotors" is completely wrong.

the renesis-engine which powers the RX8 has 2 rotors with (i hope the word is correct, me = german ) chamber volumes of 650 cc EACH (calculated as following: maximum volume of a rotary chamber - min volume of a rotary chamber). there are no pistons moving up and down, so you don't have displacement like a normal piston engine. you just can't really compare the values, so the hp/liter thingie is not to be used when talking about wankel-engines.

it's more likely to say that a rotary engine still produces more bhp if you are examining two engines that can be somehow compared in "displacement" (one piston engine, one rotary engine) due to friction losses and rotating parts. a normal 4-stroke-engine has to keep the camshafts rotating, keep pushing valves down and so on. this eats horses. a lot of horses. a rotary engine has no valvetrain, so there are no losses. and then there is also the fact that piston engines have to compensate inertia on every piston dead center (upper and lower). this also eats many many little horses. the rotors in a rotary engine are always in a circular motion, so there is no inertia to compensate and there is also no valvetrain that eats power.

Great insights, Zane. Brings rotarys to a whole new light.

[zenjoe]

rotaries are completely different than piston engines and people really dont account for that. Yes the engine only has 1.3 liters of displacement between its two rotors, that is how it is officially measured. But in piston engine land, they measure displacement by how much displacement is fired per 2 crankshaft rotations (because most engines are 4 stroke, they need 2 complete engine rotations to fire all of its cylinders). This would mean that the rotary is 2.6 liters in displacement.

Now look at some other specifics.

Power to weight ratio? rotary rules
Power to size ratio? rotary is king
Power to displacement? is depends on how you look at rotaries.

There are 4 rotor rotarys, called 26b's (made from 2 13b engines). the official displacement is 2.6 liters, in piston engine terms that would be 5.2 liters. I have seen a couple at 1000whp on 92 octane gas using a monster turbo. There are not to many 5.2 liter v8's that will do that on pump gas. 13b engines will make 500whp on pump gas. will your 2.6 liter anything make that kind of power on pump gas? Some probably, but not to many. Also when going Naturally aspirated, 13b engines will produce close to 350whp when ported correctly.

If you don't believe any of this, all can be confirmed at www.rx7club.com

Here is a vid of evil7 making 1200hp on the chassis dyno

1. Ford 302 with a "monster" turbo will make 100rwhp easily. And that's only 4.9L, not 5.2. Stroke it and turbo it and you have more than 1000hp.

2. RB26 will make 500whp all day long.

3. 350whp out of a 13b is pretty damn impressive.

Way to dig up the past.

The rotary engine has not been around as long, so piston engine math/ capacity measurements are adapted to get some sort of answer.

For a 4 stroke, it only inhales once every 720deg rotation of the crank, so every two revs

For a 2 stroke it only inhales once every 360deg of crank rotation, so every rev.

For a wankel rotary it inhales every 1080deg of crank rotation, so once every three revs.

*** To have a working engine, all faces need to do work *** to apply a wankel rotary to common piston engine formula you need to use 1/3 or 2/3rd's of its actual displacement to make a calcualtion work.

For 2 stroke formula
13B=1308cc

For 4 stroke formula
13B=2616cc

For Wankel forumla
13B=3924cc (654x3- 3 sides of rotor-(equal to piston faces) x2- cos 2 rotors in engine)

Its about TIME. The rotary completes nothing untill 1080deg of crank rotation but you can do a part displacement calcualtion and modify its true rating by 1/3rd's to make it conform to a common equation, same applies for racing bodies (class comparisons to 4 strokes and 2 strokes)

I took some of this from another site. Hopefully it makes sense to you guys.
