And no, I do not and never have owned an RX7.

Let's see.. 2.0l in our engine terms would be equivalent to a 4.0L.. making 600hp. I don't think that's all that impressive for a high compression race gas motor..

how many 4.0l do you know that make 600hp? i know alot of 408's (6.6L) who can't make 500 whp.
Efficiancy wise it's a 4.0 but dissplacement it's still only a 2.0 the efficiany gets double because of the second power stroke.

I'm too lazy to describe to a t what we are talking about, but we are talking about if you compare a b20 to a piston engine it would be equivalent to 4.0l engine. A v8 does not fire all 8 of its cylinders in 1 cycle. The b20 uses all of its displacement. This is no advantage really, just different.. If it made exactly 600 hp, it'd be about 150hp/l. Not out of the ordinary for a piston engine race gas high compression engine, exactly like what you are describing. A 800-900hp SBC engine is not abnormal for extreme drag racing or circle track cars.. I can guarantee you there's more SBC 350-357's doing 850 than there is b20's making 600. Just due to the extreme amount of cup engines and pro stock chevy sbc's out there. Just because you've seen some street car ls1's barely make 550hp doesn't really mean a fair comparison. The rotary has no real advantage.. it's torque isn't that great, fuel consumption is high, less reliability, and more emissions with everything being equal. I mean, let's be for real.. if the rotary engine was the best solution out there.. every car in america would now be using a wankel. It's not allowed in 2.0 classes due to the fact it's basically equivalent to our 4.0l engine. it's different... not superior.
Back to the post.. I don't think the cars exist either... if they do, I'd bet on the t/a with equal driver/traction, but I'd say close race as well.
Peace,
Josh

Ask the Japanese about that, they would smack you in the face. Rotaries are very relaible over there, and now they are even getting more relaible over here. We finally have some shops that know how to work on the engnines. They have luxury cars with rotaries in them. Oh, and how do you know? Experience?

Thats what you get for thinking.

1)A B20 is a piston engine. I mean damn.
2)A B20 does not fire all its cylinders in one cycle either. Crap.
3)A B20 and an LS1 are both 4 stroke engines. That means for every 4 strokes, each cylinder fires one power stroke:
Piston at TDC goes down, drawing in air.
Piston goes up, compressing air. (At the end of this, you have rotated the crank once.)
Boom, piston is forced down by ignition of air and fuel.
piston goes back up, expelling exsaust.
The rotary is not the best solution. If your so convinced SBCs are, why id Chevy the only real volume performance car maker using them?
OHCs are cheaper to make. They are easier to assemble from a production engineering standpoint. Neither makes them better motors for performance, but it does mean thats what automakers tend to go with. So it really depends on how you define best solution.

1) I thought the 20b was a tri-rotor?
2) If it's a rotary, then that would mean that while the chevy fires one bank, the rotary has used all its displacment.
3) No pistons in a tri-rotor.
I did not say I was convinced that SBC's are.. I'm just convinced that no rotary is any more superior than any of the other engines out there. I backed up that example with the fact that a race SBC engines make 150 hp/l frequently, not that they are the only one ever to achieve this. In fact, TONS of cars do 150 hp/l, and if you ask me there are a ton of motors better than a tri-rotor for just about every solution.. it's not like a tri-rotor has any type of size, consumption, emissions advantage.
EDIT: Excuse the b20 statement in previous post, I own a honda civic hatch also and was lookin up b20 swaps for torque that same day. It has a little p.o.s. d15 in there now.
Peace,
Josh

20B - Rotors
2 Different engines there bud
And a 3 rotor makes 150 hp per liter in stock form.
SBC's do it in race form.
There are a couple 20B's that make 400 hp per liter in street cars. How many SBC's doing that?
The rotary is a crazy *** motor, known for hp per liter and crazy RPM's. Noone said it was the best motor ever or anything. But a SBC has none of those advantages either. There are much better motors for each application.
And don't be misinformed man, the 20B isn't allowed in small engine classes like those because it destroyed everything thrown at it, it wasn't even fair.
And there are huge debates on whether the 20b/13b are double there rated liters or not. Noone has ever truly won the debate one way or the other. Mazda still wins as of now.
Hold on, what is this arguement even over?
