The 2ZZ was built NA! If that dumbass SRT4 guy wants to bash on Boosted Toyotas... Tell him to shove an 800 hp 3S-GTE up his hoo-haa!

...which "SRT-4 guy" are we calling out here? Shouldn't be me, cause I own a Yaris.
...regardless, you'll have to do 2x better than 800 hp on a Toyota 4 cylinder to get my attention.

Info, "The most prominent 4-rotor engine from Mazda was used exclusively for various Mazda-built GT cars (including the 767 and 787B) in replacement of the older 13J. In 1991 this engine in a 787B became the first from outside the U.S. or Western Europe and the first (and so far only) car with a rotary engine to win outright the 24 hours of Le Mans race. It displaced 2622 cc and built 700 hp (522 kW) at 9000RPM. The engine design originates as a single 13B with: an additional rotor and housing added at each end, continually variable geometry intakes, and an additional (third) spark plug. The R26B's engine block can be purchased at retail from Mazdaspeed, but no internal parts are available to the general public." |

Okay. You show me a small displacement rotary and I'll show you a larger displacement engine that can give the same power and more torque with more reliability. You can get more than 700 hp off a cheaper 302 than you can that rotary...with more torque and reliability.
I'm not here to argue that small displacement engines are all that and a bag of chips...what I've been saying is, that there's nothing really that a small displacement engine can do powerwise that a bigger one can't. This isn't to say that I don't think that the rotary engine is an amazing engine...I do! It's just that a lot of people here think that what they have is THE be all and end all to power production (or at least they insinuate that). Hell, we use small engines...but there is a limit to the output. That top fuel celica 4.6 liter 4 is only running low 5's as I remember. The idea that only small displacement engine have R&D put into them is ludicrous beyond reasoning. I don't know what else there is to say.

Can a high-displacement engine rev to ridiculous RPMs like small-displacement sportbike engines? This is a question, I'm not being a prick... I actually want to know.

This is where the rotary will kill everything. Easily revving to well over 10k. Allows you to hold in gear longer and less shifting. To each his own really. Me, I'll take the high revving low torque option anyday. Other might choose a ridiculously large big block. Meh, point is.....do what you want. Anything can be done with the right amount of $$$

This is all application specific I say. You could have a high displacement motor but it be say a V12. In which case I see it being able to rev pretty high due to rotating mass. Now a huge say 502 V8??? Never. Not without spending ridonkulus amounts of money in super exotic light weight materials.

The engine I'm building for my 70 Mach 1 is a 351c (5.8L for those that don't speak old school). Redline is going to be 8000 rpm. It's no sport bike redline, but still real impressive for a street car.

jdub,
I like the way you put that. I completely understand. Honestly, I'm a big fan of ALMS racing, JGTC, DTM, BTC, World Challenge Touring and GT racing. Engine types and sizes vary heavily in those series. I really like the underdog engines...like a rotary or a 6 versus and 8 cylinder. I don't think there's too many things that give me more pleasure than seeing a BMW beat one of those factory backed CTS-V's (although the sound of those CTS's is incredible). One of the cars I enjoyed seeing most was the Volvo S60R in the Speed World Challenge when it came to PIR a couple years back. The sound of that engine's turbo was spectacular! Driving a boosted car at the time, I was more than happy to be wearing my "Death by PSI" shirt at that race. Oh! The sound of the Porsche cup cars downshifting before the chicanes at PIR...oh man! If I could have that sound in my car when I downshifted...I could die a happy man. To those who have seen a Porsche cup race in person, you know what I mean. I more than grasp the idea of why there are rotary fans out there. I just don't like the idea of having to rev the engine up to speeds like that just to make horsepower because of the lack of torque. That's just me. Hell, the NHRA engines can't go past 8400 someodd RPM because it's all tire spin at that point. Safety first eh?

Generally an engine with a stroke longer than it’s bore yields higher torque, but requires a lower rev limit. A larger bore than it’s stroke means less torque but higher max revs… In the end we’re all shooting for more horsepower, and since HP is the sum of TQ x Revs, either route works. Take any motor, add more tq by increasing the stroke and you’ll increase it’s power. Or shorten the stoke to add more revs (as long as your tq curve isn’t falling like a rock) you’ll increase it’s power. The “replacement for displacement” argument really makes me chuckle every time I see it… mainly because both sides of the arguments are correct, it simply depends on the context. For instance if you’re saying modern technology enables smaller engines to make the same or more power than older, larger engines you really don’t have to look far to see that’s very true. Here’s a prime example… the Trans Am featured in Smoky and the Bandit only put out 180hp at the flywheel from 6.5L, while today we’re posting in a thread about a 1.5L engine putting that much to the drive wheels. That’s impressive. On the other hand, if that same technology was applied to a 6.5L engine it’d be making a s#!t ton more than 180whp, unless someone is REALLY bad at tuning. All else being equal, bigger is better… but things aren’t always equal, and technology *can* make all the difference. |

Case in point, ALMS and World Challenge GT racing. My argument was really not about diplacement but rather the idea and insinuation that small engines are the only ones with R&D put into them these days...which is a completely blind and ignorant.
